Sometime I’m in a hurry and delete a VM’s disk image before removing it from libvirt/virsh, which leaves a lingering, dead reference to that VM.
The following fixes this:

sudo virsh –connect qemu:///system undefine vm_to_be_removed

Replace vm_to_be_removed with your VM name.

Followed this recipe first, but got bogged down on the home-brew tools and very detailed guest config. However, this blog has the best description and config I’ve ever seen for bridge networking on CentOS – worked like a charm.
Finally got everything working with these (much simpler) instructions using a centos6 guest from the openvz template download site.
