RE: [Xen-devel] VMX status report. Xen: #17917 & Xen0: #583 -- no new issue

Yes, the bug shows at cpu hot-plug patch. What I mean is that the root cause is 
some improper handling of MSI/MSI-X on domain-destruction path.

Well actually this is not on the domain-destruction path -- it's on the cpu
hotplug path. But anyhow if you have some bugfixes in the pipeline, that's
great!
