Hi
This is test report on Xen 4.5 RC4, from Intel OTC VMM Team.
Platform: Grantley-EP, Ivytown-EP
We found these issue blow. Hoping corresponding patches can be committed in Xen 4.5 release.
Issue 1 -- detach a vt-d assigned device from guest, then reattach it to guest, will fail.
http://lists.xen.org/archives/html/xen-devel/2014-11/msg01342.html
Issue 2 -- attach/detach vt-d devices (both physical and virtual fucntions) to domain, more than 1 time, will fail with errors
http://lists.xenproject.org/archives/html/xen-devel/2014-12/msg02016.html
Note: this depends on issue 1. need to apply issue 1's patch to get it.
Issue 3 -- 1GB hugepage support on X86_64 with HVM guest requires hacks in the guest config
http://lists.xenproject.org/archives/html/xen-devel/2014-11/msg02624.html
Best Regards,
Robert Ho

This one has been in existence for quite a while so it can go in Xen 4.6
