So no block device detected, and no xen-related module loaded. That's weird.
Two parts of this problem.
The first part is why would the emulated block device be missing. It
should still be there if PV drivers was not loaded.
Are you using the same dom0 (xen and dom0 kernel) and domU config file
for both the working F14 and F15? If yes, try:
- "xen_emul_unplug=never" on kernel command line. See
http://www.kernel.org/doc/Documentation/kernel-parameters.txt
- make sure you use "hda" on domU config file
Second part, F15's boot/config-2.6.38.6-26.rc1.fc15.x86_64 has these entries:
CONFIG_XEN_PLATFORM_PCI=m
CONFIG_XEN_BLKDEV_FRONTEND=m
So if you could add xen-platform-pci.ko and xen-blkfront.ko to the
install initrd, you should be able to use PV drivers directly. Not
sure what's the easiest way to do it though (maybe unpack initrd, add
some files, and repack it).
