Comment 33 for bug 862136

I have the same problem with 11.10 and switched back to kernel 2.6.38-11 from 11.04.

The next problem I had was, that libvirt couldn't find radvd. It looks like it is no libvirt dependency and the one who compiled the debian packages didn't have it installed, so the path to /usr/sbin/radvd was not embedded in the libvirt library or daemon binary.

I solved this by creating the libvirt package from source package. I didn't modify anything, just a recompile, but with radvd installed before.
