However, if you start the cowd daemon ahead of time

My current dom0 was compiled from xen-3.0.2-2 source + dm patches. I cannot find the cowd daemon. I wonder if it is something I need to compile separately.

and point your
domain's disk at the target device (/dev/mapper/something), then it
should work.

 Which device do you mean for the target device? Previously, my installation configuration file was like disk = ["file:/xenimages/windowsbase.img,ioemu:hda,w" ]. Then, I changed to disk = ["dmu:dscow:/tmp/windowsbase.dscow:/xenimages/windowsbase.img,ioemu:hda,w" ]. Is the /tmp/windowsbase.dscow what you meant?

Thank you.

Note that qemu-dm should be able to use qcow files like qemu does, so
that may be the best option for you, if you're mostly interested in
HVM domains.
