KVM Virsh tricks

Using KVM Virsh

log into the rails or sgd-virt
To get into the kvm prompt.
>sudo virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

To see all virtuals running or not on this machine:
>list --all

virsh # list --all
 Id Name                 State
----------------------------------
  1 sgd-vm02             running
  2 sgd-vm03             running
  3 sgd-vm06             running
  4 sgd-vm07             running
  5 cherry-vm08          running
  7 sgd-vm13             running
  9 cherry-vm14          running


To stop a virtual:
>>shutdown sgd-vm02
This will bring the virtual machine down to an off state. You need to do this if you are going to remove it.
To start a virtual that has already been created:
>start sgd-vm03
it will need a minute to come all the way up.

To remove a virtual altogether, this has to be done if youa re rebuilding the same virtual 
>undefine sgd-vm03
This will get rid of all trace of the virtual, unless you saved it or made a backup copy.

To save a copy of the virtual
>save sgd-vm03
this will save a copy of the image and store it for retrieval

To retrieve a copy of a saved virtual:
>restore sgd-vm03
This should work and bring it back up.

To save a copy by hand:
>cd /vm03
>cp  to filename.bak
Now you have a copy of the image of sgd-vm03, keep this in a directory and you can reuse it on any kvm server.

There is a sudo for virsh:
>sudosh
