Are you sure you use a HVMPV kernel then, and not plain PV loaded directly
by Xen ?
AFAIK, the BIOS started in the HVM domU, as well as the OS bootloader started
from this BIOS, only knows how to access the virtual disk via the emulated
PCIIDE controller. If you start a HVM domU with no ioemu virtual disk,
then the HVM's BIOS doesn't have a disk to boot from.
