HE> misc_util.c(70): Connecting to libvirt with uri `qemu:///system' HE> device_parsing.c(818): Unknown domain type -1 Okay, I should start looking at the code before I speak :) It looks to me like you have a KVM domain with XML that doesn't fit with my type detection logic, hence the -1 domain type. Right now, if the <os> block has a type of 'hvm', and the <domain> tag has a type of 'kvm', then we consider it to be a KVM domain. However, I'm assuming you're missing the type in your <os> block, which really shouldn't be necessary (it's needed to determine between Xen PV and FV), so maybe removing that check would fix this problem. I'll submit a patch to do that; please report if it fixes your problem. Thanks! -- Dan Smith IBM Linux Technology Center Open Hypervisor Team email: danms@us.ibm.com
