A few things to try: - Sync the mac addresses - Add <model type='rtl8139'/> to the <interface> block - Make sure acpi + apic, memory, vcpu settings are the same It could also be that the jump from f7 to f12 is just too drastic, and behavior has changed enough at the qemu/kvm level to upset the guest. Not really sure though. - Cole -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
