Multiple users accessing KVM
How can I have multiple users access our kernel-based virtual machine at the same time? Can we use some sort of screen sharing to get around the 1 user at a time limit?

Answer Wiki:
This can easily be done by letting users ssh into a screen session. First, install the screen package:
On RedHat
# yum install screen
On Debian/Ubuntu:
$ sudo apt-get install screen
If you want them to all have the same screen session, then include this in the .bashrc file:
...
if [ ps auxw|grep [s]creen > /dev/null ]; then
screen
else
screen -x
fi
...
If screen is not running.. it will spawn a new screen session. If it already IS running, it will have the new user JOIN the screen session.
Now if you want them to each get their OWN screen session, then you will need to write a custom script to spawn screen with X number of sessions.. and then auto join new people to n+1 screen (where n is the number of users currently logged in).
It's not a perfect solution, but you're asking for a work around here.

Is there really such “one user at a time” limit for any virtual machine, including KVM? May be you are considering a limit of the OS running in virtual machine?
Petoka..
It sounds like he’s on a restricted host config.

@Tweeks: Just my point – “screen” utility is working on OS level, not VM.
@NewnanIT: some more information about your OS – some flavor of Linux, or Windows (as I figure, more probably) will be of utter help for solving the problem…
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It comes with a loadable kernel module, kvm.ko, which provides the core virtualization infrastructure and a processor-specific module, kvm-intel.ko or kvm-amd.ko. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine can have its own private virtualized hardware: a network card, disk, graphics adapter,

@Carlosdl: Carlos, it seems somebody again copy/pasting in the forum like our dear friend Rachil?
I agree Petko, this looks exactly as those posts from Rechil, but he has resurrected with his own name (I saw a couple of answers by him recently), so, maybe he has a … friend ? (please, no)
