I think we can use 3.4-RCx kernel as dom0 when sending the report next time.

Added the config in the BZ.  It doesn't have any cpu weight in config. 
Some other person also reported this issue in the mailing list several days ago.

OK. Leave it here as a tracking.

Will update this status in next report based on 3.4-RCx.

Yeah, it still exist.  It may be a similar issue with BZ# 1812.
According to our recent testing, it something about VNC console.
Also added some latest info in the BZ.

This is about 32bit Xen.
As we don't test 32bit Xen for a long time, we may update it when we're free.

When doing 'echo 1 >../reset', I get the same error as list in the BZ.
"/sys/bus/pci/devices/0000:09:00.0/reset returned -1: Invalid argument".
This bug only exists when we use 'pcistub' to hide a device.
If using 'pciback' to hide the device, it doesn't show any error info.
If Xen will support both 'pcisback' and 'pcistub' to hide a device, I'll leave 
the bug open in BZ.

Oh, it has been fixed by Jan. Marked as verified.

Not sure about this, because we don't use LVM in our testing.
We're still testing this bug. If any update, we'll add it in the BZ.

We found it is related to 'stdgva' option in guest config file.
If 'stdvga=1' and 'vnc=1', the guest is not slow when shutdown.
If 'stdvga=0' and 'vnc=1', guest shutdown will be very slow.
Also updated BZ, you can get detailed info in BZ.
