Something I'm experiencing here using graphics/vga pass-through with Xen
4....rebooting the domU does not seem to work. I'm running Windows XP, and,
when I reboot, the domain appears to just shut down. A look at the xend.log
file, however, shows the following entries:
[2010-04-15 15:24:15 17820] DEBUG (XendDomainInfo:2543)
XendDomainInfo.constructDomain
[2010-04-15 15:24:15 17820] ERROR (XendDomainInfo:486) VM start failed
Traceback (most recent call last):

VmError: failed to assign device 00:02.0: maybe it has already been assigned to

So, looks like the graphics PCI device (00:02.0) is not being released in a
timely fashion, and, when Xen tries to boot a new domain, it sees it as already
in use. Anyone know any way around this - even just something like inserting a
reboot delay in so that Xen waits a couple of seconds before trying to restart
the domain?
Also, with regard to my post late last week - if anyone has any insight on
putting the video card into power save mode (or shutting it down completely)
when the domU shuts down, I'd appreciate it!
Thanks - Nick
