Hi Arik,

By "empty" you mean the webadmin reports the host being running 0 VMs? 
If so, that's not the case, actually the VM count seems to be correct in 
relation to "qemu-*" processes (about 32 VMs), I can even see the 
machines in the "Virtual machines" tab of the host, it's just they are 
all marked with the '?' mark.

Thanks.
