HVM Domain stops when searching for PCI devices in DOS

HVM Domain stops when searching for PCI devices in DOS

Hi,

I just ran a little test whith xen-3.0.5-rc2 and using an floppy-image
[1] I came across: It contains a bootable Caldera DOS including CD-ROM
drives for various drive types.
On of those drives, in detail the "ASPI8DOS.SYS" scans the PCI bus for
SCSI devices which results in a "stop" of the domain (domain state
changes to "------" even when if "on_crash", "on_poweroff" and
"on_reboot" are set to "destroy")

I used this floppy image previously with xen-3.0.4 and it did not
crashed when loading ASPI8DOS.SYS.

Can somebody reproduce this problem?

I'm not sure it makes any difference, but is this on an AMD or Intel processor?

Yeah, DRDOS in fact revealed *two* bugs. :-) These are fixed by changesets
14902 and 14903. You can pick these up shortly from
http://xenbits.xensource.com/staging/xen-unstable.hg

 Thanks!
