many qemu-dm process but only a few domain exist.

Hi,

I have a non-VT enabled machine and some domains run on it. After
running various domain operations(shutdown, reboot, resume, suspend ...)
 for 3 days. I find that there are many qemu-dm vnc process, much more
than the domain processes.

what the problem? It looks like an error occured when xen try to get
vncpasswd. Where this vncpasswd stored?

thanks!
