[Xen-devel] Xen4.2-rc1 test result

["Ren, Yongjie" <yongjie.ren@xxxxxxxxx>]

Hi All,
We did a round testing for Xen 4.2 RC1 (CS#25692) with Linux 3.4.7 dom0.
We covered VT-d, SR-IOV, Power Management, TXT, IVB new features, HSW new 
features.
We covered many cases for HVM guests (both Redhat Linux and MS Windows guest).
We tested on Westmere-EP, SandyBridge-EP, IvyBridge desktop, and Haswell 
hardware platforms.
We found no new issues, and verified 1 fixed bug.

Fixed bug (1):
1. parameter 'maxvcpus' causes hvm guest boots up with wrong vcpu number
http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1825
-- Fixed by Yang from Intel.

The following are some of the old issues which we guess are something important.
Some of the old issues:
1. long stop during the guest boot process (too slow bootup)
  http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1821
2. Poor performance when do guest save/restore and migration with linux 3.x dom0
  http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1784
3. 'xl vcpu-set' can't decrease the vCPU number of a HVM guest
  http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1822
4. after detaching a VF from a guest, shutdown the guest is very slow
  http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1812
5. Dom0 cannot be shutdown before PCI detachment from guest and when pci 
assignment conflicts
  (xl allows same PCI device to be assigned to multiple guests)
  http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1826
6. Guest hang after resuming from S3
