These messages are not very surprising. Is it working ?
No, when try to start HVM on Xen unstable with pv_ops kernel I get this error:
Ah. This is rather odd. Normally I would hope that xend would report
an exit status. (I haven't tried pvops with qemu.)
Hm, I'm getting:
[2009-02-23 15:26:18 4380] WARNING (image:482) domain win7: device model
failure: pid 5409: died due to signal 7; see /var/log/xen/qemu-dm-win7.log
Hm, signal 7 - SIGBUS. I wonder if
Using stub domains doesn't work either.
I would suggest running qemu-dm under strace. This can be done easily
enough with a simple wrapper script, something like:
#!/bin/sh
set -e
exec strace -vvs500 -f -o /root/qemu-dm.strace \
/usr/lib/xen/bin/qemu-dm "$@"
and then give the name of the script as device_model in your config file.
I see:
