I am running XEN on an debian etch. For clustering purposes I wanted to boot fedora as virtual machine.
That works (except for nfs mounts) fine using the paravortualization features.
But fully virtulalized guests do not even boot, I do not get any sensefull error message, my config file looks like:
<domain type='xen'> <name>werewolf</name>
<os> <type>hvm</type> <loader>/usr/lib/xen-3.0.3-1/boot/hvmloader</loader>
<kernel>/data/virtual/kernel/kvm1/vmlinuz-2.6.18-6-amd64</kernel>
<initrd>/data/virtual/kernel/kvm1/initrd.img-2.6.18-6-amd64</initrd> <cmdline>root=/dev/hda1</cmdline>
Booting fullyvirtualized guests off a kernel+initrd is a very new feature in Xen. Your <loader> path suggests you are using Xen 3.0.3 which is no where near new enough to support this. You need to boot of CDROM or hardisk instead.

Urm, you're trying to use KVM with Xen which just won't work. You need to point to Xen's version of QEMU /usr/lib/xen/bin/qemu-dm or whereever Debian puts it.
all I get when tryin virsh create is:
xend_post: error from xen daemon: (xend.err "Error creating domain: (0, 'Error')")
This looks like a fairly old Xen which didn't know how to give proper error messages. You'll have to check /var/log/xen/ for more details, but it'll certainly be the kernel/initrd stuff that's broken, and the device emulator too.
