I've tried that :-
name = "Ubuntu810HVM"
builder = "hvm"
memory = "2048"
disk = ['phy:/dev/loop0,hdc:cdrom,r','phy:/dev/sdb7,hda,w']
vif = [ 'type=ioemu,bridge=eth0' ]
# device_model = "/usr/lib64/xen/bin/qemu-dm"
device_model = "device_model_wrap.sh"
kernel = "/usr/lib/xen/boot/hvmloader"
vnc=1
boot="d"
usb=1
usbdevice="tablet"
vcpus=1
cat device_model_wrap.sh
#!/bin/sh
set -e
exec strace -vvs500 -f -o ~boris/vm/qemu-dm.strace \
/usr/lib64/xen/bin/qemu-dm "$@"
Same behavior. File qemu-dm.strace has not been created at all.
Content of log file under /var/log/xen is just the same.
xm dmesg is much less informative. Just 2-3 HVM lines

Ah. This is rather odd. Normally I would hope that xend would report
an exit status. (I haven't tried pvops with
qemu.)
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.
Ian.
