Description of problem: I used xen on my computer (F7) before, but now I would like to try kvm instead (graphic support under kernel-xen sucks). When trying to restart fullvirt guest (host is x86_64, guest i386) using virtual-manager, I get the error mentioned in summary (full Python backtrace is attached). Version-Release number of selected component (if applicable): kernel-2.6.22.5-76.fc7 libvirt-0.3.2-1.fc7 virt-manager-0.4.0-2.fc7 How reproducible: 100% (tried four times) Steps to Reproduce: 1.start virtual-manager -c qemu:///system 2.click on new 3.walk through the wizards as if creating new fullvirt guest (with hardware acceleration) for CentOS 5, using local iso image, and "default" network. Actual results: error happens Expected results: starting CentOS 5 guest in VNC Additional info:

If the network isn't running, it merely needs to be started using virt-manager UI, or 'virsh net-start'
