[Xen-devel] qemu-3.4-testing problems...

[Mark Johnson <johnson.nh@xxxxxxxxx>]

FYI...

We have a user who's 64-bit Windows 2k8 guest consistently
cores qemu-dm with the latest qemu-3.4-testing.git bits.
I haven't been able to reproduce it with Linux (HVM), Solaris(HVM), or a
64-bit Windows 2k8 guest. Not sure what's different about his guest.

I was able to have him backout the recent changes pushed on 10/20
(with no other changes) and his guest no longer crashes...

Anyone else seeing similar problems?
