[Xen-devel] Xen-4.0.0 RC2 Test Report. Xen: #20852 & Dom0: #e65323...
Hi All, Here is the test report for Xen-4.0.0-rc2(Xen C/S 20852). Our testing covers following features, like VT-x/VT-x2, VT-d, SR-IOV, Power Management, RAS, and TXT. There are 8 new bugs exposed in this testing compared with RC1 testing, including 5 P1 bugs. Vcpu hot-add can not work well in guest. Dom0 S3 with TXT can cause Xen hang. And txt-stat tool can cause Pv_ops Dom0 hang. There is one new VT-d bugs found with MSI device, which is fixed in latest c/s 20855. For bug fixing, the VT-d assignment issue cause Xen crash issue is fixed. Two RAS bugs about cpu hotplug and NUMA are fixed also. Guest boot up slow issue on NHM-EX is fixed. And we downgrade Dom0 OOM bug priority to P2 because it seems a normal behavior. We use latest Pv_ops as Dom0 in our testing.
