It's a bit of a guesswork:

  1. The space at 'file:/data/ubuntu-12.10-desktop- amd64.iso,hdc:cdrom,r' shouldn't be there. If you copy/pasted your config file, you need to fix that.

  2. Check device_model='/usr/lib/xen-4.1/qemu-dm' to see if qemu-dm is in fact there. In my (Ubuntu-based) Linux Mint 13 distro it's /usr/lib/xen-4.1/bin/qemu-dm

  3. disk = ['phy:/dev/server/ubuntu-hvm,hda,w' seems to specify a regular disk, not a LVM volume. It shouldn't cause a problem, but I believe the partition (or LVM volume) needs to be unformatted.

  4. Don't know if it's related, but vif = ['bridge=eth0'] looks strange. Is eth0 your bridge? Anyway this is the last thing I would check, after everything else fails.

  5. You may want to try virt-manager (a GUI, you need to install libvirt and perhaps some more packages). Make sure you uncomment the

           (xend-unix-server yes)

    line in /etc/xen/xend-config.sxp
