[one-users] libvirt and kvm permission problem.

[Idafen Santana Pérez]

I'm on CentOS 5.5. it seems I can connect with virsh under oneadmin account.

[oneadmin at granada ~]$ virsh -c qemu:///system
Welcome to virsh, the virtualization interactive terminal.

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


I've solved the problem, but I am not sure if this is the best/right way.

Regards,
Idafen
