KVM: Starting / Stopping Guest Operating Systems With virsh Command

Posted on in Categories , , , last updated May 6, 2017

The virsh command can be used to mange local or remote guest operating systems. The program can be used to create, pause, and shutdown domains. It can also be used to list current domains.

List Running VMS

Type the following command:
# virsh list
Sample outputs:

 Id Name                 State
----------------------------------
  1 centos.nixcraft.in   running
  2 freebsd              running

Shut Down A Guest

# virsh list
# virsh shutdown dominName
# virsh shutdown freebsd
# virsh shutdown 3

Rebooting A Guest

# virsh list
# virsh reboot domaiName
# virsh reboot 3
# virsh reboot win2008biz

Forcefully Stop A Guest

Force a guest to stop with the virsh command if it is not responding or crashed
# virsh list
# virsh destroy domainName
# virsh destroy openbsd.nixcraft.in

Get Information About Guest

# virsh list
# virsh dominfo dominName
# virsh dominfo 2
# virsh dominfo freebsd

  1. I have been looking for this article. I was wanting to set up a virtual lab to practice for my RHCE and this article totally covers the pieces I was missing to make it work.

    Thank you.

  2. Any chance you can add an index to all of the articles in this series, linking them together?

    Would make it easy to navigate in order, rather than having to search the site and piece the order together.

    Not critical, but would put the series together. Good write-ups!

  3. Starting / Stopping Guest Operating Systems With virsh Command >>> I don’t see how the helll you start another dead end seriously waste of time here
