Then change it. Choose individual email instead of digest. It's
somewhat selfish to expect others to help you when you don't even want
to make such small effort.

It's not supposed to appear. Look at my previous answer, and you
should see that I told you to
"- determine where domU's vnc port is using "virsh vncdisplay winxp"
- connect to it, using something like "vncviewer localhost:n", where
"n" is the number from virsh output."

Note that you can also run "virt-manager" (the GUI is
self-explanatory), or run "virt-viewer domU_name" to connect to domU's
vnc console.

then again, the fact that even "virsh list" doesn't work for you makes
it somewhat complicated.

If "virsh list" shows nothing but "xm list" shows domUs, then
something is definitely wrong with your setup.
At this point my suggestion is to use a known working configuration.
Something like reinstalling your system from scratch, and use Centos
5.3 with bundled Xen.

Another alternative is to dump virsh/libvirtd altogether. In that
case, you could PROBABLY determine the vnc port to connect using
something like

netstat -anp | grep qemu-dm | grep LISTEN

if it shows something like this

tcp        0      0      *
       LISTEN      14977/qemu-dm

then you can see the console using this command

vncviewer localhost:1
