 This is the actual error, the LVM errors turned out to be a red herring.

---------
XENBUS: Device with no driver: device/vbd/2049
XENBUS: Device with no driver: device/vbd/2050
XENBUS: Device with no driver: device/vif/0

 You were actually right. It appears the LVm errors were non-critical and the critical error is the lack of xen device drivers in the kernel or the initrd. I tried with --with=xenblk.ko, but didn't work. I will try once more and report back.

 Thanks for the solution.
