Thanks for your help. However, how can I make the VM visible to libvirt of that kind.? Even with third party tools?

I am puzzled , can someone help me? Running a VM directly via qemu-kvm makes the VM invisible to libvirt, unless you first run 'virsh qemu-attach'. There are certain restrictions for this to work, such as having a socket-based monitor on the guest. 'virsh list' can only list VMs known to libvirt. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
