[Xen-users] Graphics Pass-Through: Reboot Doesn't Work



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):
  File "/usr/lib64/python2.6/site-packages/xen/xend/XendDomainInfo.py", line 
471, in start
    XendTask.log_progress(0, 30, self._constructDomain)
  File "/usr/lib64/python2.6/site-packages/xen/xend/XendTask.py", line 209, in 
log_progress
    retval = func(*args, **kwds)
  File "/usr/lib64/python2.6/site-packages/xen/xend/XendDomainInfo.py", line 
2705, in _constructDomain
    " it doesn't exist." % (bus, dev, func))
VmError: failed to assign device 00:02.0: maybe it has already been assigned to 
other domain, or maybe it doesn't exist.
[2010-04-15 15:24:15 17820] DEBUG (XendDomainInfo:3107) XendDomainInfo.destroy: 
domid=32
[2010-04-15 15:24:15 17820] DEBUG (XendDomainInfo:2451) No device model

[2010-04-15 15:24:15 17820] ERROR (XendDomainInfo:130) Domain construction 
failed

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
