Well, I did know that, actually. The problem is that when configured
this way using raw disks, the VM *won't boot*. The configuration that I
had working in F11 before the disk rebuild had the controller type
changed to IDE because otherwise it doesn't work.
BTW, the CD-ROM shows up in VMware as being IDE.
I have a grub floppy image that I use as a boot loader for the VM. The
boot loader starts and chains to the WinXP loader, then the VM hangs. I
should point out that the WinXP system disk was not changed when I
repartitioned. The grub on the bare metal machine dual boots just fine.
If I replace the controller type in the .vmdk file, I get a message that
the controller type is changed. The boot starts, but it bluescreens.
