Description of problem:

Performed a DVD clean install (not upgrade) of FC5t3 on my Dual Core Opteron
system. This system already had Windows XP installed on the first partition on
the local SATA disk. Anaconda detected that parition as "pdc_hdcadijdg" (which
is odd, but plausible). The Windows partition is of type NTFS. When I originally
put Windows on the SATA drive, I left the second half of the disk unpartitioned,
for Linux.

I made one partition, of type ext3, in the second half of the disk, mounted at
/. No swap partition (this box has 2GB of memory).

I selected virtualization as one of the options, and the install completed
successfully. Upon rebooting, it had installed the hypervisor kernel (only?),
but when I tried to boot into it, I received a kernel panic.

This is what I could capture from the screen:

Windows XP is still bootable and happy, but FC3t3 is definitely not.
