It's not DISPLAY that's the problem.  I don't know exactly what it is,
but when I changed back to gdm from kdm, the root type problems went
away.

It seems to work fine with just a cd-image.

VERY good advice.  From the log file I learned that the startup
problems I had were due to the cdr iso file being on nfs storage.
Once I copied it to the local disk it worked fine.  Changing the
virt_use_nfs, qemu_use_nfs didn't work because virt-manager tries
to set the security label, and that's not supported on this version
of nfs.

I am using whatever the current F11/x86_64 updates has.  I couldn't
find any libvirt in updates-testing.
