Boris can probably answer this better, but in general what Xen version
you use can be separated from what kernel you use. So if you have Xen
3.4.1, you can go ahead with libvirt 0.7.0.6 regardess of which kernel
you use.

>From the look of this you're starting vncviewer process on the
server(?) but it does not have correct DISPLAY environment set. Try
"echo $DISPLAY". It should have something like ":0.0". If not, and
you're using ssh to access the server, you need X forwarding.
If it's on your local notebook/PC, then probably you start terminal as
normal user then run "su -". If that's the case, you can run "su -p -"
instead of just "su -". It will preserve necessary environment
variables (including DISPLAY. At least this works on Ubuntu).
Another option is to simply run vncviewer as normal user (you don't
need root for that).

This shows there are two domUs with vnc listening on 5900 and 5901.

You can use LVM or file, your choice. If you use file-based image,
it's best to use tap:aio:/ instead of file:/ or manually using
losetup.
