I can't seem to get a RHEL4 i386 HVM guest to boot on RHEL5.2 x86_64  
when using the PV vbd either.
The initrd contains the xen-vbd driver and xen-platform-pci but it  
dies when trying to boot:
ACPI: (supports S5)

It seems to see the devices and the xen-vnif ethernet device works  
well. Have I missed something simple?

Tom
