Hi Simon,<br>
I recently had this problem when I was using xen with opennebula. This might be worth a try (it worked for me)<br>
1. Make sure qemu-dm is installed (not necessary with xen as it comes in the xen-hypervisor package so I think that's the package name)<br>
2. Locate the correct qemu binary file location<br>
3. Create a symbolic link to the correct qemu binary path<br>
"ln -s /usr/bin/kvm <correct qemu binary path here>"<br>
<br>
Hope this helps and let me know if it works!!!<br>
<br>
Yours Sincerely,<br>
Marc Reilly<br>
