Re: [Xen-devel] most of qcow images cannot boot since c/s 16958.

I'm not sure what causes that. Hanging 'xm destroy' is because qemu-dm is
now killed by SIGTERM rather than SIGKILL. I think that was a mistake to
change, so I'll probably revert that. But it doesn't explain why your
qemu-dm went bad in the first place. I think you will have to work out
exactly which changeset caused the problem.
