Out of the box you are not going to be able to run virsh commands on the cli as root. Libvirt, Virsh, and KVM are just not that tightly integrated in RHEV.

You can however, follow the procedure below, and create a user and password to use for authentication.

# saslpasswd2 -a libvirt fatmin
Password:
Again (for verification):

Now enter the credentials you entered above.

# virsh list –all
Please enter your authentication name: fatmin
Please enter your password:
Id Name State

10 HostedEngine running

Now you can shut down or start a VM. Here I am shutting down my RHEV HostedEngine.

# virsh destroy HostedEngine
Please enter your authentication name: fatmin
Please enter your password:
Domain HostedEngine destroyed
