Hi Folks,
I create a file backed vbd to boot a guest VM as described in the Xen's user manual in section 'Using File-backed VBDs". The Dom0 and the VBD contain Suse Linux Enterprise Server 10 (X86_64). I am not able to boot the guest VM. During the boot process the INIT process generates an error saying

I am using the latest unstable Xen tree. Below is the full log. Thanks a lot for any help.
