Holy moly, that did the trick! Thanks!

With HVM, phy: disks on LVs won't work, although the same host has many PV CentOS hosts running no problem from LVs. The file: disks work with no problems. The disk configurations I've tried: Neither works: disk = [ 'phy:domU/w2k30.root,ioemu:hda,w' ] disk = [ 'phy:domU/w2k30.root,hda,w' ] Selected logs: [2008-12-19 12:00:11 3365] INFO (XendDomainInfo:1504) createDevice: vbd : \ {'uuid': 'dada2695-5fdd-85c9-3990-8d1978a35782', 'bootable': 1, 'driver': 'ioemu', \ 'dev': 'ioemu:hda', 'uname': 'phy:domU/w2k30.root', 'mode': 'w'} [2008-12-19 12:00:12 3365] INFO (XendDomainInfo:1273) Domain has shutdown: name=w2k30 id=63 reason=poweroff.

The phy: disk image was created by dding the file from the installed file: image into the blank phy: LV. If booted from the win2k3 install CD (cdrom specified as file:, disk as phy:), the install hangs forever at "Setup is starting Windows", presumably as it's trying to grok the hard drive configuration. I managed to get the domain to pause during the Plex86/Bocks Bios, and see the disk detection as follows: ata0 master: QEMU HARDDISK ATA-7 Hard-Disk ( 0 MBytes) ata0 slave: Unknown device Booting from Hard Disk... At this point the domain shuts down.
