• Can GPU capabilities impact virtual machine performance?

  - by Dave White

  While this many not seem like a programming question directly, it impacts my development activities and so it seems like it belongs here. It seems that more and more developers are turning to virtual environments for development activities on their computers, SharePoint development being a prime example. Also, as a trainer, I have virtual training environments for all of the classes that I teach. I recently purchased a new Dell E6510 to travel around with. It has the i7 620M (Dual core, HyperThreaded cpu running at 2.66GHz) and 8 GB of memory. Reading the spec sheet, it sounded like it would be a great laptop to carry around and run virtual machines on. Getting the laptop though, I've been pretty disappointed with the user experience of developing in a virtual machine. Giving the Virtual Machine 4 GB of memory, it was slow and I could type complete sentences and watch the VM "catchup". My company has training laptops that we provide for our classes. They are Dell Precision M6400 Intel Core 2 Duo P8700 running at 2.54Ghz with 8 GB of memory and the experience on this laptops is night and day compared to the E6510. They are crisp and you barely aware that you are running in a virtual environment. Since the E6510 should be faster in all categories than the M6400, I couldn't understand why the new laptop was slower, so I did a component by component comparison and the only place where the E6510 is less performant than the M6400 is the graphics department. The M6400 is running a nVidia FX 2700m GPU and the E6510 is running a nVidia 3100M GPU. Looking at benchmarks of the two GPUs suggest that the FX 2700M is twice as fast as the 3100M. http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html 3100M = 111th (E6510) FX 2700m = 47th (Precision M6400) Radeon HD 5870 = 8th (Alienware) The host OS is Windows 7 64bit as is the guest OS, running in Virtual Box 3.1.8 with Guest Additions installed on the guest. The IDE being used in the virtual environment is VS 2010 Premium. So after that long setup, my question is: Is the GPU significantly impacting the virtual machine's performance or are there other factors that I'm not looking at that I can use to boost the vm's performance? Do we now have to consider GPU performance when purchasing laptops where we expect to use virtualized development environments? Thanks in advance. Cheers, Dave

• Pattern filters in Laravel 4

  - by ali A

  I want to make a pattern route, to redirect users to login page when they are not logged in. I searched but couldn't find a solution. as always Laravel's Documentation is useless! I have this in my filter.php Route::filter('auth', function() { if (Auth::guest()) return Redirect::guest('login'); }); Route::filter('auth.basic', function() { return Auth::basic(); }); And this route in my routes.php Route::when('/*', 'auth' ); but It's not working. How can I do that?

• When compiling programs to run inside a VM, what should march and mtune be set to?

  - by Russ

  With VMs being slave to whatever the host machine is providing, what compiler flags should be provided to gcc? I would normally think that -march=native would be what you would use when compiling for a dedicated box, but the fine detail that -march=native is going to as indicated in this article makes me extremely wary of using it. So... what to set -march and -mtune to inside a VM? For a specific example... My specific case right now is compiling python (and more) in a linux guest inside a KVM-based "cloud" host that I have no real control over the host hardware (aside from 'simple' stuff like CPU GHz m CPU count, and available RAM). Currently, cpuinfo tells me I've got an "AMD Opteron(tm) Processor 6176" but I honestly don't know (yet) if that is reliable and whether the guest can get moved around to different architectures on me to meet the host's infrastructure shuffling needs (sounds hairy/unlikely). All I can really guarantee is my OS, which is a 64-bit linux kernel where uname -m yields x86_64.

• VMWare Tools StartUp Script

  - by Horst Walter

  I am on the latest version of VMWare Workstation. In my VMWareTools I have configrued an individual script file (start.bat) to be started when the (guest) OS is booted. Unfortuantely it does not run when starting the guest system as intended. When pressing "run now" it works Running the script from CMD works as well I have changed the service (VMWareTools service) to run under different users - no success All Users (of the service) have had Administrator privileges I have no idea what is going wrong. Maybe someone is having an idea ....

• PHP MySQL Zend-ACL - Find all inherited items (Children / Parents)

  - by Scoobler

  I have one MySQL DB table like the following, the resources table: id | name | type 1 | guest | user 2 | member | user 3 | moderator | user 4 | owner | user 5 | admin | user 6 | index | controller Onto the next table, the rules table: id | user_id | rule | resource_id | extras 1 | 2 | 3 | 1 | null 2 | 3 | 3 | 2 | null 3 | 4 | 3 | 3 | null 4 | 5 | 3 | 4 | null 5 | 6 | 1 | 1 | index,login,register 6 | 6 | 2 | 2 | login,register 7 | 6 | 1 | 2 | logout OK, sorry for the length, but I am trying to give a full picture of what I am trying to do. So the way it works, a role (aka user) can be granted (rule: 1) access to a controller, a role can inherit (rule: 3) access from another role or a role and be denied (rule: 2) access to a controller. (A user is a resource and a controller is a resource) Access to actions are granted / denied using the extras column. This all works, its not a problem with setting up the ACL within zend. What I am now trying to do is show the relationships; to do that I need to find the lowest level a role is granted access to a controller stopping if it has explicitly been removed. I plan on listing the roles. When I click a role, I want it to show all the controllers that role has access to. Then clicking on a controller shows the actions the role is allowed to do. So in the example above, a guest is allowed to view the index action of the index controller along with the login action. A member inherits the same access, but is then denied access to the login action and register action. A moderator inherits the rules of a member. So if I were to select the role moderator. I want to see the controller index listed. If I click on the controller, it should show the allowed actions as being action: index. (which was originally granted to the guest, but hasn't since been dissallowed) Is there any examples to doing this. I am obviously working with the Zend MVC (PHP) and MySQL. Even just a persudo code example would be a helpful starting point - this is one of the last parts of the jigsaw I am putting together. P.S. Obviously I have the ACL object - is it going to be easier to interigate that or is it better to do it my self via PHP/MySQL? The aim will be, show what a role can access which will then allow me to add or edit a role, controller and action in a GUI style (that is somewhat the easy bit) - currently I am updating the DB manually as I have been building the site.

• Secure way to run other people code (sandbox) on my server?

  - by amikazmi

  I want to make a web service that run other people code locally... Naturally, I want to limit their code access to certain "sandbox" directory, and that they wont be able to connect to other parts of my server (DB, main webserver, etc) Whats the best way to do it? Run VMware/Virtualbox: (+) I guess it's as secure as it gets.. even if someone manage to "hack".. they only hack the guest machine (+) can limit the cpu & memory the process uses (+) easy to setup.. just create the VM (-) harder to "connect" the sandbox directory from the host to the guest (-) wasting extra memory and cpu for managing the VM Run underprivileged user: (+) doesnt waste extra resources (+) sandbox directory is just a plain directory (?) cant limit cpu and memory? (?) dont know if it's secure enough... Any other way? Server running Fedora Core 8, the "other" codes written in Java & C++

• Windows can see Ubuntu Server printer, but can't print to it

  - by Mike

  I have an old desktop that I'm trying to set up as a home backup/print server. Backup was trivial, but am having issues getting the printing to work. The printer is connected to the server running Ubuntu Server 9.10 (no gui). If I access the printer via http://hostname:631/printers/, I am able to print a test page, so I know the printer is working; however, I am having no luck from Windows. Windows can see the printer when browsed via \hostname\, but I am unable to connect. Windows says "Windows cannot connect to the printer" without indicating why. Any suggestions?

• KVM + Cloudmin + IpTables

  I have a KVM virtualization on a machine. I use Ubuntu Server + Cloudmin (in order to manage virtual machine instances). On a host system I have four network interfaces: ebadmin@saturn:/var/log$ ifconfig br0 Link encap:Ethernet HWaddr 10:78:d2:ec:16:38 inet addr:192.168.0.253 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::1278:d2ff:feec:1638/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:589337 errors:0 dropped:0 overruns:0 frame:0 TX packets:334357 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:753652448 (753.6 MB) TX bytes:43385198 (43.3 MB) br1 Link encap:Ethernet HWaddr 6e:a4:06:39:26:60 inet addr:192.168.10.1 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::6ca4:6ff:fe39:2660/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16995 errors:0 dropped:0 overruns:0 frame:0 TX packets:13309 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2059264 (2.0 MB) TX bytes:1763980 (1.7 MB) eth0 Link encap:Ethernet HWaddr 10:78:d2:ec:16:38 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:610558 errors:0 dropped:0 overruns:0 frame:0 TX packets:332382 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:769477564 (769.4 MB) TX bytes:44360402 (44.3 MB) Interrupt:20 Memory:fe400000-fe420000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:239632 errors:0 dropped:0 overruns:0 frame:0 TX packets:239632 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:50738052 (50.7 MB) TX bytes:50738052 (50.7 MB) tap0 Link encap:Ethernet HWaddr 6e:a4:06:39:26:60 inet6 addr: fe80::6ca4:6ff:fe39:2660/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:17821 errors:0 dropped:0 overruns:0 frame:0 TX packets:13703 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:2370468 (2.3 MB) TX bytes:1782356 (1.7 MB) br0 is connected to a real network, br1 is used to create a private network shared between guest systems. Now I need to configure iptables for network access. First of all I allow ssh sessions on port 8022 on the host system, then I allow all connections in state RELATED, ESTABLISHED. This is working ok. I install another system as guest, it's IP address is 192.168.10.2, and now I have two problems: I want to allow the access from this host to the outside world, cannot accomplish this. I can ssh from the host. I want to be able to ssh to the guest from the outside world using 8023 port. Cannot accomplish this. Full iptables configuration is following: ebadmin@saturn:/var/log$ sudo iptables --list [sudo] password for ebadmin: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:8022 ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED LOG all -- anywhere anywhere LOG level warning Chain FORWARD (policy ACCEPT) target prot opt source destination LOG all -- anywhere anywhere LOG level warning Chain OUTPUT (policy ACCEPT) target prot opt source destination LOG all -- anywhere anywhere LOG level warning ebadmin@saturn:/var/log$ sudo iptables -t nat --list Chain PREROUTING (policy ACCEPT) target prot opt source destination DNAT tcp -- anywhere anywhere tcp spt:8023 to:192.168.10.2:22 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination The worst of all is that I don't know how to interpret iptables logs. I don't see the final decision of the firewall. Need help urgently.

• How to use more than 3 virtual disks in Linux using CentOS and XenServer

  - by 010110110101

  I've attached 5 virtual disks to a Virtual Machine in Citrix XenServer. The VM has the xs-tools installed. Initially it said that it couldn't add so many disks. After I installed the xs-tools, it let me add all the disks. But /dev doesn't show all the disks. It shows these: /dev/xvda /dev/xvdb /dev/xvdc /dev/cdrom Perhaps it is bound by the limits of an IDE bus? (3 disks + CD-ROM) If so, how does one change the VM to use SCSI? Edit: According to the documentation: 2.6.3. VM Block Devices In the PV Linux case, block devices are passed through as PV devices. XenServer does not attempt to emulate SCSI or IDE, but instead provides a more suitable interface in the virtual environment in the form of xvd* devices. It is also possible to get an sd* device using the same mechanism, where the PV driver inside the VM takes over the SCSI device namespace. This is not desirable so it is best to use xvd* where possible for PV guests (this is the default for Debian and RHEL). For Windows or other fully virtualized guests, XenServer emulates an IDE bus in the form of an hd* device. When using Windows, installing the Citrix Tools for Virtual Machines installs a special PV driver that works in a similar way to Linux, except in the fully virtualized environment. Still, with 5 virtual disks attached, I don't see the other xvd devices. Edit #2: (attached requested info) Host Machine: XenServer 6.1 Linux version 2.6.32.43-0.4.1.xs1.6.10.777.170770xen (geeko@buildhost) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-51)) #1 SMP Wed Apr 17 05:52:03 EDT 2013 Guest Machine: CentOS release 6.4 (Final) Linux version 2.6.32-358.6.2.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Thu May 16 20:59:36 UTC 2013 Output of 'fdisk -l' on Guest Machine: Note, the disk beyond the first 3 attached are not displaying -- there should be 4 100GB disks.

This tab shows you the local file system associated with the instance and any shared storage libraries mounted by Ops Center. More detailed information about file system storage is available under the Analytics tab under the sub-tab named Charts. Here, you can select and display the individual mount points of an OS, and export the utilization data if desired: In this example, the OS instance has a basic root file partition and several NFS directories. Each file system mount point can be independently chosen for display in the Ops Center chart. File Systems and Incident  Reporting Every asset managed by Ops Center has a "monitoring policy", which determines what represents a reportable issue with the asset. The policy is made up of a bunch of monitoring rules, where each rule describes An attribute to monitor The conditions which represent an issue The level or levels of severity for the issue When the conditions are met, Ops Center sends a notification and creates an incident. By default, OS instances have three monitoring rules associated with file systems: File System Reachability: Triggers an incident if a file system is not reachable NAS Library Status: Triggers an incident for a value of "WARNING" or "DEGRADED" for a NAS-based file system File System Used Space Percentage: Triggers an incident when file system utilization grows beyond defined thresholds You can view these rules in the Monitoring tab for an OS: Of course, the default monitoring rules is that they apply to every file system associated with an OS instance. As a result, any issue with NAS accessibility or disk utilization will trigger an incident. This can cause incidents for file systems to be reported multiple times if the same shared storage is used by many assets, as shown in this screen shot: Depending on the level of control you'd like, there are a number of ways to fine tune incident reporting. Note that any changes to an asset's monitoring policy will detach it from the default, creating a new monitoring policy for the asset. If you'd like, you can extract a monitoring policy from an asset, which allows you to save it and apply the customized monitoring profile to other OS assets. Solution #1: Modify the Reporting Thresholds In some cases, you may want to modify the basic conditions for incident reporting in your file system. The changes you make to a default monitoring rule will apply to all of the file systems associated with your operating system. Selecting the File Systems Used Space Percentage entry and clicking the "Edit Alert Monitoring Rule Parameters" button opens a pop-up dialog which allows you to modify the rule. The first screen lets you decide when you will check for file system usage, and how long you will wait before opening an incident in Ops Center. By default, Ops Center monitors continuously and reports disk utilization issues which exist for more than 15 minutes. The second screen lets you define actual threshold values. By default, Ops Center opens a Warning level incident is utilization rises above 80%, and a Critical level incident for utilization above 95% Solution #2: Disable Incident Reporting for File System If you'd rather not report file system incidents, you can disable the monitoring rules altogether. In this case, you can select the monitoring rules and click the "Disable Alert Monitoring Rule(s)" button to open the pop-up confirmation dialog. Like the first solution, this option affects all file system monitoring. It allows you to completely disable incident reporting for NAS library status or file system space consumption. Solution #3: Create New Monitoring Rules for Specific File Systems If you'd like to have the greatest flexibility when monitoring file systems, you can create entirely new rules. Clicking the "Add Alert Monitoring Rule" (the icon with the green plus sign) opens a wizard which allows you to define a new rule.  This rule will be based on a threshold, and will be used to monitor operating system assets. We'd like to add a rule to track disk utilization for a specific file system - the /nfs-guest directory. To do this, we specify the following attribute FileSystemUsages.name=/nfs-guest.usedSpacePercentage The value of name in the attribute allows us to define a specific NFS shared directory or file system... in the case of this OS, we could have chosen any of the values shown in the File Systems Utilization chart at the beginning of this article. usedSpacePercentage lets us define a threshold based on the percentage of total disk space used. There are a number of other values that we could use for threshold-based monitoring of FileSystemUsages, including freeSpace freeSpacePercentage totalSpace usedSpace usedSpacePercentage The final sections of the screen allow us to determine when to monitor for disk usage, and how long to wait after utilization reaches a threshold before creating an incident. The next screen lets us define the threshold values and severity levels for the monitoring rule: If historical data is available, Ops Center will display it in the screen. Clicking the Apply button will create the new monitoring rule and active it in your monitoring policy. If you combine this with one of the previous solutions, you can precisely define which file systems will generate incidents and notifications. For example, this monitoring policy has the default "File System Used Space Percentage" rule disabled, but the new rule reports ONLY on utilization for the /nfs-guest directory.

• SQLAuthority News – First SQL Bangalore Event Report – Nov 24, 2012 – SQL Server User Group Bangalore

  - by pinaldave

  A very common question I often receive - Do we have SQL Server User Group in Bangalore? Yes! SQL Bangalore – we had very first meeting on Nov 24, 2012 and very soon we are going to have another User Group meeting. The goal is to keep up a monthly rhythm of User Group meeting. If you are in Bangalore area please join the Facebook page and you will keep on getting regular update about SQL Server. In the very first meeting we have five 30 minute session and had a fantastic time. We had the best of the best speakers presenting all the five sessions. The event was inaugurated by Vinod Kumar M by presenting on T-SQL Pitfalls. His excellent and eye-opening session was followed by Manas Dash. He enlightened everybody with functions introduced in SQL Server 2012. We had a surprise guest from Mumbai – Raj Chaodhary. If you know him he has a very interesting way to present sessions and he presented on SQL Joins. His hard to follow act was followed by Sudeepta who presented on Contained Database. This subject is quite entertaining and interesting. My session was last in order and I was eagerly waiting to present. I had decided to do something new this time so I had created around 52 slides and two demos. I was committed to go over all the 52 slides and both of the demos in 25 minutes of the time. I had interesting story as well. Though, I was a bit nervous I was able to go over a complete slide deck and demo in 25 minutes of the time I had. We also were very fortunate to have international guest Lynn Langit from USA present at the event as well. She presented an overview of the Big Data in very little time – something not everyone can do it efficiently. We are very thankful to our sponsor Pluralsight for awarding USD 300 worth Annual Subscription. It was the most awaited moment of the day. Well, overall we had a great fun with 100+ attendees learning SQL Server.

• Mini Book Review of IronRuby Unleashed by Shay Friedman

  - by Eric Nelson

  When I get some time (and hell starts to look a little chilly) I would love to do a more detailed review. But I wanted to get something “out there” as I really like this book and reviews of it seem a little thin on the ground. In brief: Is it a good book? Yes Would I recommend this book to a .NET developer who was new to Ruby? Yes (This is me by the way) Would I recommend this book to a Ruby developer who was new to .NET ? Yes Would I recommend this book to a developer who sometimes does Ruby and sometimes does .NET? Yes Would I recommend this book to a developer new to .NET and new to Ruby? Yes The above demonstrates how well balanced this book is (IMHO). What I like about it: Its assumes pretty much no knowledge of IronRuby or .NET. All it asks is that you are a developer interested in IronRuby. Yet it manages to cover off the topics in a good degree of detail. If you are a Ruby developer you skip Part 2, if you are a .NET developer you skip some of Part 1 and whizz through the short intros to the individual technologies such as WPF. It is definitely not a “lets makes the manual look pretty” book – this is original content thoughtfully written and presented. It is pretty comprehensive – in 500 pages it packs in  Intro to IronRuby Intro to .NET Intro to Ruby Using IronRuby with Windows Forms, ASP.NET, WPF, Silverlight etc Getting Rails working with IronRuby Unit testing with IronRuby – which I think is an excellent way for a .NET developer to start using IronRuby Embedding IronRuby in a .NET app  - another interesting “first step” for a .NET developer What I didn’t like: Err… nothing yet. Ok, If I am being picky then the start of chapter 2 irked me a little as it went through the history of .NET. “The first version [of the .NET Framework] wasn’t that great”.  Felt pretty good to me compared to Java and C++ development at the time :-) Buy on Amazon UK | Buy on Amazon USA Related Links: Posts from the author Shay Friedman on IronRuby Guest Post: What's IronRuby, and how do I put it on Rails?

• Fun with Sun Ray, 3D, Oracle VM x86 and SRIOV

  - by wim.coekaerts

  One of the things I like about my job is that I get to play around with stuff and make use of the technologies we work on in my teams. Sort of my own little playground. It allows me to study the products in great detail and put them to use in ways that individual product teams don't always intend them to be used for :) but that makes it fun. I have a lot of this set up at home because... work is sort of hobby and I just like to tinker with it. Anyway, a few weeks ago I was looking at my sun ray rig at home and how well 3D works. Google Earth and some basic opengl tests like glxspheres combined with virtualgl. It resulted in some very cool demos recorded with my little camera (sorry for the crappy quality of the video :-) : OVDC (soft client) on my mac Sun Ray 2FS Never mind the hickups during zoom, that's because I was using the scrollwheel on my mouse and I can't scroll uninterrupted :) Anyway, this is quite cool ! The setup for this was the following : Sun Ray on LAN, Sun Ray Server 5 latest installed on OL5.5 inside a VM running on Oracle VM 2.2 (hardware virt, with a virtual network (vif)) and the virtualgl rendering happened on another box (wopr5) that runs linux on a little atom D520 with an ION2 gpu. So network goes from Sun Ray to Sun Ray Server to wopr5 and back. Given that this is full screen 3D it puts a good amount of load on the network and it's pretty cool that SRS was just a VM :) So, separately, I had written a little blog entry about using sriov and oracle vm a while back. link to sriov blog entry Last night when I came home I wanted to do some more playing around with SRIOV and live migrate. To do this, I wanted to set up a VM with 2 network interfaces, one virtual network (vif) and then one that's one of the SRIOV virtual functions from my network card. Inside the guest they show as eth0 and eth1, and then bond them using a standard linux bonding device (bond0 here) with active active links. The goal here is that on live migrate, we would detach the VF (eth1 in guest in this case), the bond would then just hum along on eth0 (vif) we can live migrate the VM and then on the other server after the migrate completes we re-attach a VF to the VM there and eth1 pops up again and the bond uses both eth0/eth1 to do its work. So, to set this up, I figured, why not use my sun ray server VM because the 3D work generates a nice network load and is very latency/timing sensitive. In the end, I ran glxspheres on my sunray server (vm) displaying on my sun ray 2 fs and while that was running, I did my live migrate test of this vm (unplug pci VF, migrate, reconnect vf) and guess what, it just kept running :) veryyyyyy cool. now, it was supposed to, but it's always nice to see it actually work, for real. Here's a diagram of it. No gimics - just real technology at work ! enjoy :)

• Debootstrap chroot Installation Error

  - by frogstarr78

  During initial installation of Ubuntu Server 12.04.1 LTS (64-bit) as a guest VM on XenServer 6.1 I'm getting this error: Debootstrap warning Warning: Failure trying to run: chroot /target dpkg --force-depends --install /var/cache/apt/archives/debconf_1.5.42ubuntu1_all.deb Any ideas? Just tried the same ISO on VirtualBox and it errored in the same way, although on different packages: base_files_6.5ubuntu6.2_amd64.deb and base-passwd_3.5.24_amd64.deb I'm redownloading and trying another ISO.
