• Good reasons to keep 32-bit Microsoft Windows desktop OSes

  - by Mark Henderson

  Server software has been 64-bit only for a while now (Since Server 2008 R2 for Windows, even earlier for Exchange and Sharepoint) and even Ubuntu are pushing you away from 32-bit versions for their server OSes. But is there any good, quantifiable reason to keep a 32-bit desktop operating system maintained? We're preparing our Windows 8 images for the (unfortunate?) few that will be early adopters. The majority of our desktop computers have 4gb or less of RAM, but I would love to not have to bother supporting a 32-bit flavoured operating system any more. Any reason why I should?

• One bigger Virtual Machine in Cloud

  - by flyer

  I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with e.g. 12 cores? ------------------------------- | VM (12c) | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | VM (4c) | VM (4c) | VM (4c) | ------------------------------- | Bare Metal (8c) | ------------------------------- I need this information to have a bigger picture to continue.

• Choosing between cloud (Cloudfoundry ) and virtual servers - for developers

  - by Mike Z

  I just came across some articles on how to setup your own cloud using Cloudfoundry and Ubuntu, this got me thinking, choosing our infrastructure, if we want to use our own servers what's the advantage of cloud on virtual servers vs just using virtual servers, VPN? If we now develop for the cloud later if we need help we can quickly move on to a cloud provider, but other than that what's the advantage and disadvantage of private cloud in these areas? speed of development, testing, deployment server management security having an extra layer (cloud) will that have a hit on server performance, how big? any other advantage/disadvantage?

• Migrated Virtual Machine Shows Up in Both Datastores

  - by Backstage

  Hi, We're using Vsphere client 4.0.0 Build 208111 with Virtual Center Server same version and same build. I have one vm with only one disk that is shown on 2 different datastores. If I look through VMs and Templates I see only 1 vm. If I look through Datastores screen, I see it in datastore-002 and datastore-003. If I go to settings of the virtual machine on datastore-002 and check the disk, I see the path as datastore-003. How can I fix this ?

• Virtual fiber channel HBA in Solaris

  - by Phil

  We are trying to set up some virtual Fibre Channel HBA's in Solaris. This seems to be possible with NPIV. Creating NPIV's in a Solaris global zone works fine, but passing that NPIV to a zone didn't work at all. We tried to pass the NPIV as following: # zonecfg -z zone1 'info' zonename: studentz1 [...] device: match: /devices/pci@0,0/pci8086,25f9@6/pci8086,350c@0,3/pci1077,140@4/fp@1,0:devctl allow-partition not specified allow-raw-io not specified Wat we want to do is, set up an environment for SAN exercises. We don't have a physical host per student, so we try to virtualise that in some way (Solaris zones or VMware). It should be possible to display the WWN of the virtual HBA and mount the storage presented by the disk subsystem. Any ideas to pass the NPIV to a solaris zone or to virtualise this with vmware?

• Server 2008 blue screen after login - no desktop

  - by Jake

  I came into work today to find that our Windows Server 2008 used as a terminal server for the Thin Clients was not loading the users desktops. What I have found out is that when I login via Remote Desktop, after applying user settings, it gets to the stage of 'Preaparing your desktop', but then the screen just goes blue. I have tried rebooting several times with no luck, and logging in locally at the server with no luck. Does anyone have any suggestions? I do not think that it could be a virus attack as we run antivirus on the server with OpenDNS filtering. Yesterday a software restriction policy was set up to only allow programs in the following directories to run if that could be the problem, although it was working fine all day yesterday. C:\program files C:\programdata C:\windows Thank you. Jake

• Supply username and password to mstsc

  - by Will

  In previous versions of the remote desktop client there were methods of passing in the password through various methods. Has anybody found a good method using the latest remote desktop client? I'm aware of LaunchRDP but that doesn't meet our needs. Perhaps somebody knows the algorithm so I can dynamically assemble RDP connection files?

• how to connect virtual box os and local machine

  - by Nrew

  This question is in connection to this question asked by a user before: http://superuser.com/questions/73470/virtualbox-vdi-file-to-vmware On how to convert vdi to vmdk or vmx using vmware converter. How do I connect the windows xp that is in virtual box to the local computer (windows 7) in a network. Because I got this error while I tried following this instruction: Give the IP address, username and password of the remote machine that you would like to convert and then hit next I got this error in vmware converter: Unable to connect the specified host 10.0.2.15 which is the ip address of the xp machine inside virtual box. It also said that there is a network configuration problem. And when I inputted the ip address from whatismyip.com which should be the same as the ip address on local machine. I didn't get the previous error but I got another one, it said that: insufficient permissions to connect to "ip address" What solution can you suggest for this problem?

• Deploy virtual PC based on snapshot using Hyper-V

  - by user27786

  I have a server with Hyper-V configured, it is easy to create a new virtual machine using the management tools, but it can take some time. I often see those hosts that say "We can have your server ready in 5 seconds". And I wonder how do they manage this? I would also like to deploy a full functional clean server in 5 seconds. So how is this done? Is it by first installing a clean server, then take a snapshot of that for later to deploy a new server based on that snapshot? I tried doing this, but I did not find any where to install a new virtual machine based on the snapshot. Anyone got any thoughts to share on this?

• Connect to virtual host computer from within virtualbox

  - by Nicky De Maeyer

  I'm currently developing on an ubuntu karmic. For this I've installed lampp with a virtual host on apache so http://myproject/ is mapped to my project's root directory. Now to test the website in IE I've installed an XP machine on a virtualBox OSE. Ive managed to get the virtual host working on the XP by adding its to the hostfile, like this: 255.255.255.255 myproject where 255.255.255.255 is the ip adress of the host computer (my ubuntu). Now every day when I come to work and plug in my computer to the network, my IP has changed. so When i boot the XP I have to change the IP in the hostfile to my new IP. Is there any way where I can set the ip to somthing the XP will recognise as the host machine? I've tried replacing the IP in the hostfile by the host computer name, but that does not seem to work... This would make my like a bit easier :)

• Virtual NIC on VM couldn't ping externally after Vmotion

  - by ToreTrygg

  Today I vmotioned 5 MS SQL 2005 servers over to a new DRS Cluster. All SQL servers use the "Production_LAN" network and a single virtual NIC of type "VMXNET 3". The first 4 SQL VM (Windows 2003 Standard or Enterprise x32 bit) vmotioned over without a hitch. The last SQL VM I vmotioned (Windows 2003 Standard x64 bit R2) vmotioned over without error, but I upon completion, I could no longer ping the VM. I went into the VM and could not even ping the gateway, however I could ping the loopback. This SQL server is extremely busy in comparison with the previous 4 VM's. I restarted the server and it came back up with the virtual nic working just fine. The build of both servers (vmotioner and vmotionee) is ESX 4.0.0 175625 - So, pre-update 1. Should I suspect the network switch/VM for possibly not updating the mac table on the switch? Anybody else ever have this issue or know what may have caused it? Thank you!

• How to configure cookieless virtual host in Apache2?

  - by xzyfer

  We run over a hundred web applications (growing daily) on a LAMP stack using Apache2 on Ubuntu 10.04. We've would like all requests to static content to be cookieless. We host applications on many different domains, a majority of which as SaSS applications. Many of the domains host instances of the applications on sub domains, ie. myapp.example.com, myapp2.example.com myapp.otherexample.com etc.. At the moment all static content is server relative to the (sub)domain requesting it. As far as I understand the process, I would need to setup a new domain, eg. staticexample.com. In this case is special configuration in the virtual host for this domain required to ensure no cookies are served? Also, would it be possible to instead use static.example.com? In this case what configurations would I need in my virtual host for this subdomain to ensure no cookies are served?

• How to set robots.txt globally in nginx for all virtual hosts

  - by anup

  I am trying to set robots.txt for all virtual hosts under nginx http server. I was able to do it in Apache by putting the following in main httpd.conf: <Location "/robots.txt"> SetHandler None </Location> Alias /robots.txt /var/www/html/robots.txt I tried doing something similar with nginx by adding the lines given below (a) within nginx.conf and (b) as include conf.d/robots.conf location ^~ /robots.txt { alias /var/www/html/robots.txt; } I have tried with '=' and even put it in one of the virtual host to test it. Nothing seemed to work. What am I missing here? Is there another way to achieve this?

• Accessing SQL Server in Windows XP Mode Virtual Pc

  - by DavidStein

  I have a laptop running 64bit Windows 7 Ultimate. I created a Virtual PC using Microsoft XP Mode. I've installed SQL Server 2000 on the Virtual Machine. I have SQL Server 2008 R2 installed on the Windows 7 machine (laptop). I can browse to the SQL 2000 instance (it sees it), but I cannot successfully connect using either Windows or SQL Server Authentication. I don't get an error, the attempt just times out. I have the Windows XP Mode Firewall turned off, and there doesn't appear to be anything in the Event logs either. Any ideas how I can query the XP Mode SQL Server from the Windows 7 machine?

• Virtual PC - Display Issue with Ubuntu Server

  - by Christopher R

  Hi Everyone, I just did a clean install of Ubuntu Server 9.04 in Virtual PC on the Windows 7 RC, and it seems to be having a bit of an issue with the virtual machine's display adapter. I've tried setting a VGA flag in the GRUB configuration to no avail. This is a guess, but I think it has something to do with the color console mode that gets enabled by default at boot time. The system starts booting just fine (i.e. the console looks "normal" when I'm asked to enter an LVM passphrase, etc.), but then the display goes wonky after a few seconds and I end up with this. Typing commands in bash works just fine: it's not like the system is frozen or anything, I just can't see anything that I type. The console looks exactly the way it does in the image below.

• Virtual Hosting in RHEL 5

  - by Kumar P

  We have a RHEL 5 Linux server with a few Windows XP clients. We provide web development in PHP. Now my developers as for common local PHP server for keep their projects in same place. Currently the proxy server and Samba sharing are running on the RHEL 5 server. I installed httpd, PHP and MySQL in the server. And I would like to configure virtual hosting too for LAN. What I want do for it? We have 2 Ethernet ports in the server, 1 for local connections and another one for Internet. Internet is provided by an ADSL provider. (192.168.0.0 series for ADSL modem connection and 10.1.1.0 for the LAN connection. If I want to use virtual hosting, do I need to setup local DNS server? My requirements are: setup PHP with MySQL server for local clients with multiple hosting, without disturbing proxy and Samba.

• ubuntu server 10 - slow and can't remove desktop environment

  - by Alex

  i'm running ubuntu server 10.10 with the desktop environment. simple page requests are taking over 5 seconds even when connecting to the server through our local network. i believe this is partially related to having the desktop environment installed, as the server worked faster (but not as fast as it should considering that it's on the local network), but tasksel fails every time (aptitude failed 100). my knowledge of networking and linux in general is limited. would really appreciate ideas on how i can troubleshoot this problem. oh also, in the system monitor, one of the processors is almost always around 100%. i doubt this is normal too....

• courier-imap w mysql : share a folder between 2 virtual users on debian

  - by Michael

  Hi I have a working courier-imap server on my Debian Etch private server ; users are virtual, authentificatin goes through mysql. It's been working good for years. I would like to share an imap folder between 2 users. I thought I would just have to do something like this : cd path/to/mailusers/dir ln -s path/to/user1/maildir/.folder_to_be_synched path/to/user2/maildir/ After I entered the command, I found that user2 saw a new folder in its imap client, but the folder appeared empty. It is not a permission problem because all the virtual users have the same permissions on the file system. Any idea what I could do ? thanks

• How to run multiple Linux installations on a single VirtualBox?

  - by NoCatharsis

  I just started playing with VirtualBox to check out different versions of Linux. I was wondering if it would be possible (and recommended) to set up a single virtual machine with multiple partitions - one for each separate version of Linux, one for swap memory, and one fully shared /home partition? Still new to Linux, but I've read this is a good way to partition so you can share common applications between Linux installations, however I think everything I've read is pertaining to literal partitions and not virtual machines.
