Thanks for this. WRT the need to install virt manager to avoid the
"cannot open shared object file" issue I expect just running "ldconfig"
would have worked instead.

It would also be good to understand why it is necessary to install from
source. Was it just the lack of the xencommons initscript? Debian and
Ubuntu have their own initscripts and don't reuse the xencommons script.
However it should be fairly easy to add the necessary commands to start
qemu to /etc/init.d/xen instead of rebuilding from source.

I'd expect just adding to the end of the "start)" section of the script
to work. e.g. 

                *) log_end_msg 1; exit ;;
        esac
        log_end_msg 0
+       /usr/local/bin/qemu-system-i386 -xen-domid 0 -xen-attach -name dom0 
-nographic -M xenpv -daemonize \
+          -monitor /dev/null -serial /dev/null -parallel /dev/null \
+          -pidfile /var/run/qemu-xen-dom0.pid
        ;;
  stop)
        capability_check
        case "$?" in
                0) ;;

(nb, that's not a real patch, I just typed it into my mail client as is)

If you can confirm that this works then I can try and get this fixed in
Debian at least.

Ian.
