• In place SQL 2008 upgrade vs. Side by side?

  - by Jim

  I have a SQL 2005 Std edition server with 5 databases in production, 4 db's are used by web-based apps the 5th is a desktop application. My question is should I perform an in-place upgrade or a side-by-side by creating an sql2008 instance on the same box? The machine is a VM on vmware and I'm planning on taking a snapshot before the upgrade and having a 'blackout' window during the upgrade so that I could roll back to the snapshot if things go really bad. Any previous experience and advice is appreciated.

• Change MacOS X guest screen resolution for VirtualBox

  - by Pymoo

  I have tried all alternatives and resources that I found on internet to achieve to change screen resolution in my MacOS X guest. I have the latest VirtualBox version (4.1.22) and I have MacOS X 10.6.3 Snow Leopard running in a vm guest. Some solutions that don't work for me are: Tuning virtual machine settings: Adding and in the .vbox file, or running these two commands: vboxmanage setextradata "MAC OS X" "CustomVideoMode1" "1360x768x32" vboxmanage setextradata "MAC OS X" "GUI/CustomVideoMode1" "1360x768x32" Editing Guest OS boot configuration: Modify /Library/Preferences/SystemConfiguration/com.apple.boot.plist with these lines: <key>Kernel Flags</key> <string>"Graphics Mode"="1360x768x32"</string> <key>Graphics Mode</key> <string>1360x768x32</string> Any other suggestion, something that I was missing. Thanks in advance,

• CPU/RAM usage log over a period of time to file on CentOS

  - by joel_gil

  Hi everyone Im looking for an app pr line of code that could let me observe a process, save the info in a number of variable and then put the gathered info on a file. Ive been trying with variations of top but no luck. I am running several CentOS virtual servers, VM is 2gb ram 2 processor. Maybe a script that works over a specified amount of time while writing lines with the info on a text file so at the end i can have a sort of table with the data. The thing is Im going to stress test the server and I would like to have the data to make some statistics. Any comments and suggestions are most welcome.

• VMware Workstation 7 build 203739 - Capture Movie Mouse Pointer Not Visible

  - by BMIVM

  Hi, I have noticed that whenever I create a Capture Movie, the movie is fine but the mouse pointer is not visible at all. The clicks are on buttons file menus are executed but is hard for a viewer of the capturre movie session to follow the recording smoothly. This was not a problem in previous versions of WorkStation. Is this a bug or is there a setting I can set to see the mouse pointer? Note: VM Tools are installed, Host is Vista Ultimate Edtion SP1, x64 and the guest is a Win XP SP2. Thanks in advance for your help.

• Type 1 Hypervisor on the desktop

  - by Blazemore

  I have a powerful home PC, and I've used VirtualBox to run Linux distros in Windows (and vice versa). I'm interested in trying out a lightweight type 1 hypervisor to run all my operating systems (Windows 7, Debian, Arch) and was looking for suggestions of which to pick and how to implement this. From what I gather, a type 1 hypervisor is a lightweight OS which simply provides VM management functionality. Will I get reasonable performance under each guest OS? Can all the guest OSs have access to a shared data drive, or is is best to have a storage server in another guest OS and mount it over the virtual network? What about gaming, is this feasible, or will I realistically need to run Win7 on bare metal? I'd appreciate any input.

• Autosaving on emacs or xemacs files (preferably on loss of focus)

  - by Spencer

  Ideally I want to replicate with emacs functionality from TextMate, whereby on loss of focus i.e. I click away from the buffer, my file saves. If this isn't possible, I want to customize emacs so that it will autosave the file for every character I write. When I say this I don't mean I want to autosave to the ~ backup files. I want to save the file I am currently working on. I am working on a Fedora VM. Note I am not looking for a backup or autosave. I want the file I am actually in to save, so that if I loaded the html file I am editing in a web browser it would reflect my new changes without me having to explicitly change it.

• Learning Puppet Exercise - Installing httpd package and starting service

  - by Quetzalcoatl

  I'm working my way through the Learning Puppet guide on manifests, and I am stuck on the exercise at the bottom of the page which asks you to install the httpd package and start the httpd service. So far my manifest looks like: package { 'httpd': ensure => present, } service { 'httpd': ensure => running, enable => true, } However, upon trying puppet apply on it, I get: From looking at other examples of similar manifests, I cant quite figure out what the issue is - I presume the attempt at installing the package httpd failed? Unfortunately the error message isn't particularly helpful here. Any assistance anyone can provide would be greatly appreciated. I'm running their VMWare Learning Puppet VM (PE 2.7.0) that was provided for this tutorial.

• How to "debug" a keyboard in Linux? Like pressing a key and seeing a code in a terminal.

  - by Somebody still uses you MS-DOS

  I didn't have an answer to my problem about adding additional keyboards in my Ubuntu 10.04. Questions mark is not working in my keyboard, only using Alt Gr key + W. So, I don't know if this is a problem with Ubuntu or Virtualbox itself (I'm running it inside a VM). I would like to debug this problem. The keyboard is plugged in, so when I press a key I believe something is being sent to my operating system, some code, I don't know. I would like to digg this problem, find some damn key code and find some damn *.conf file and manually fix my problem. So, do an application like this exist in Linux?

• Is a memory upgrade a viable option to fix performance issues? [closed]

  - by ratchet freak

  I'm currently seeing my PC getting bogged down by Firefox 11.0 alone with only one hundred tabs open. Resulting in a memory use of over 530M , VM size of over 800M and an insane amount of page faults (easily reaching 100 million over the course of the day). The PF delta during normal operation easily reaches 7k with peaks to 15k sometimes reaching over 20k. This leads to a (real) deterioration to response time when switching, opening and closing tabs, opening menus, typing, ... My question is: Am I right in assuming that plugging in more RAM (either adding 2x1GB or replacing the existing RAM with 2x2GB or 4x1GB) will solve this problem? My specs: Windows XP Home Edition SP3 (32 bit) Intel Core Duo 2,4 GHz 2x512MB RAM 800MHz DDR2 (dual channel) 4MB unified cache 320GB HDD Intel G33 (X3100) onboard graphics (no graphics card but PCI express x16 slot is available)

• What is shrink_slab, and why is it showing up in /var/log/messages?

  - by Steve Kehlet

  I'm investigating some application issues on a Linux system and noticed this around the time of the most recent problem, but not close enough to be definitively related: Jun 7 17:51:49 localhost kernel: shrink_slab: nr=-155456000 Jun 7 17:51:49 localhost kernel: shrink_slab: nr=-157859400 Jun 7 17:51:49 localhost kernel: shrink_slab: nr=-157833400 Jun 8 06:20:23 localhost kernel: shrink_slab: nr=-284172800 What is this? Googling isn't helping, I get that it's something with VM, but why is it suddenly showing up in /var/log/messages? Edit: I take it it's showing this because the number of pages it could free ("nr") is negative. Which is presumably a bad thing. I found patches for newer kernels that display a more useful message to this effect. Still not sure what this means though, or what I need to do about it.

• Fusion 3, Windows 7, frequent blue screens

  - by kenny6127

  Is anyone else seeing this problem? A solution would be great (hey, it's Windows, it's gonna blue screen, just gotta deal with it), but it's also nice to know if it's something specific to my configuration, or if a lot of folks are having the same issue. Here's the details: * MacBook Pro 15" unibody, 4 GB, 2.4 GHz, 10.5.8 * Fusion 3.0.1 * Windows 7 Pro, 32-bit (clean install, not migrated from Boot Camp or anything) Blue screens happen nearly every time the MBP cover is closed for a short period of time (< 3 minutes). If the cover is closed for a half hour or longer, the VM is fine. I'm guessing it might be related to sleep, but that's hard to tell, and the Windows crash dump logs are pretty useless. Thanks!

• ESXI 4.0 Slow response in opening anything accross the network on a Virtual Server running Win2008

  - by user40944

  Hi I recently installed a HP ML350G6 Server with Windows Small Business Server 200864bit, Exchange 2007. The server was running fantastically and we transferred all user data onto the new server and no problems for 2 weeks! We then installed SQL2008 and transferred the accounts package onto the server and this is where the problems started. Users are now complaining to open a work document can take 2 minutes and the same with regard to anything else. The server itself seems fine, the virtual server seems fine! No disk performance problems (doesn't go above 50% unless i really copy lots of things), no memory, (12Gb only using 7Gb) cpu (usage is low average about 15%) etc on both the VM and in Windows Task manager. I have made sure disk caching is enabled on the raid controller (which made no difference). Network cards are running 1Gb and plugged into HP GB switch. Please help!

• Hylafax with serial over IP modem

  - by zero_r

  I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

• Move and clone VirtualBox machines with filesystem commands

  - by mit

  I know of 2 ways to clone a VirtualBox machine on a linux host, one is by using the VirtualBox gui and exporting and re-importing as Appliance (in the file menu of VirtualBox). The other is by cloning only the virtual disk containers: VBoxManage clonevdi source.vdi target.vdi (Taken from http://forums.virtualbox.org/viewtopic.php?p=853#p858 ) I would have to create a new VM afterwards and use the cloned virtual disk. Is there a way I can just copy a virtual disk and the and do the rest by hand? I'd have to manually edit the ~/VirtualBox/VirtualBox.xml and insert a new disk and a new machine: Can I just make up UUIDs or how would this work? I would very much prefer this hardcore method of doing things as it allows me to freely and rapdily backup, restore, move or clone machines. Or ist there a better way to do this?

• Open Source Outlook and Exchange Alternative (for Calendar and Tasks)

  - by Elmar Weber

  We're using an Exchange Server and Outlook in a private context. Since Exchange is getting more and more of a monster to maintain and is basically the only thing running on a Windows VM Server, I'm looking for an alternative with the following properties: Server based back-end that that can be installed / deployed on my machine and is not dependent on any third party services (e.g. Google Calendar). (Easy) import of existing Outlook calendars, either via some feature of Exchange or by ex- and importing from Outlook. Roughly the basic features of the Outlook calendar (categorizations, series, etc) Synchronization with the iPhone over wireless without a hitch (e.g. double or missing entries) Any recommendations?

• Server 2012 file server security - File access through software only?

  - by user1607914

  I have just setup a server 2012 essentials R2 box as a test bed for my small business. Its running Essentials R2 as a VM on a Essentials R2 host. I have set it up to be the DC and DHCP server and joined a client. My next task is to use it as a file server but I am not quite sure how to set it up. All the client interactions with the file server will be through client side software. I therefore do not want any access to the files apart from through the software. I have looked at the ntfs permissions and there is a permission called "List Folder/Read Data" however I am unsure this will do what I want. Is it possible to give access to the files but not allow access through the windows explorer / command line?

• Software RAID underneath ESXi datastore

  - by carlpett

  I'm building an virtual environment for a small business. It is based around a single ESXi 5.1 host, which will host half a dozen or so VMs. I'm having some doubts regarding how to implement the storage though. I naturally want the datastore to be fault tolerant, but I can't get the funds for a separate storage machine, nor expensive hardware RAID solutions, so I would like to use some software RAID (lvm/mdadm, most likely). How can this be implemented? My only idea so far would be to create a VM which has the storage adapter as passthrough, puts some software RAID on top of the disks and then presents the resulting volumes "back" to the ESXi host which then creates a datastore from which other VMs get their storage presented. This does seem kind of round-about, do I have any better options? From my research, passthrough seems to come with quite a few drawbacks, such as no suspend/resume etc.

• Group policy reset upon restart?

  - by sc_ray

  Is it possible for a group policy to revert back to its original state upon server restart? Our servers are hosted as a Virtual Machine on the rack. We had to restart our server for some reason and all of a sudden we cannot remote desktop into the server any more. Pinging the server succeeds but RDPing into it fails. My assumption is that the group policy has reverted back preventing any remote desktop connections from taking place. Is that a possibility? Since the network is managed by another group, we don't have the authority to physically look into what's going on with this particular VM. Can somebody suggest some ideas? Thanks

• Device that connects to a switch via RJ45, that emulates a PC

  - by Mike Christiansen

  One of my co-workers once saw a device that plugged into a RJ45 jack, that emulated a PC. It could be configured with an IP address, and respond to pings. I was wondering if anyone knew about these, or even what they are called? This will be used to simulate a PC in a classroom environment. Thanks in advance. Edit: This is a CCNA classroom, we are looking to simulate a PC connected to an ethernet port on a router. These will be on different subnets, etc. This might be doable with a VM through VLANs and virtual switches, but then we are getting away from configuring the physical ports on the router the way we want to.

• Access Windows VPN DNS from Ubuntu

  - by user46427

  I am using Ubuntu 10.04 to access a Windows VPN. I connect to the VPN from Ubuntu, and when I open a Windows 7 virtual machine (VirtualBox), everything works great ... I can access local network drives, ping local servers, remote into local machines, etc. However, I can do none of this from Ubuntu. With the VPN connected, I cannot even ping anything within the VPN local network. I'm guessing it's a DNS issue that Windows is handling automatically but Ubuntu needs a setting somewhere to tell it to use the DNS servers of the VPN network? Any ideas? I'm a relative novice to Ubuntu, esp. VPN in Ubuntu. [EDIT] Actually, I'm almost positive it is DNS, because if I get the IP address from the Windows VM I can use Terminal Server Client to remote into a machine.

• Disk Management

  - by Mars

  I'd like to know what's with all those unnamed drives. I've always thought they are what they say they are (recoveries and what not), why are there so many of them? and why do they all say 100% Free (i.e. they're all empty!). If that's the case, what happened to my recovery? Info: I'm on Dell Inspiron 7520 Windows 8 Single Language (Had Kali installed on SSD a couple of days ago, now I've just deleted that and will install Kali on VM on SSD, that's drive (S:).

• How do I get `set show-all-if-ambiguous on` in my .inputrc to play nice with the Python interpreter?

  - by ysim

  I noticed that after I added the set show-all-if-ambiguous on line to my ~/.inputrc, whenever I pressed tab to indent a block, it would show me the bash Display all ... possibilities? (y or n) prompt, and leave me unable to indent the actual code. Is there any way to keep that line in my .inputrc but still have the tab key work as expected in the Python interpreter? This is in my VirtualBox Ubuntu 12.04 VM, if it matters. EDIT: Curiously, I now have a different issue with the Python shell that comes with Django -- when I press tab, I get Python tab completion, but only with one Tab press. I've opened a separate question here for it.
