Comment 3 Qunfang Zhang 2013-10-15 06:49:23 UTC

Hi, Eduardo

We plan to run a round of stable guest abi test on RHEL6.5 host after this bug is fixed (no rhel7 involved, juzhang will arrange the rhel7 test). So I want to confirm with you for the following stuff:

(1) Do we need to test both AMD and Intel host? 
(2) Does the guest os type matter? Could we only run with windows guest? Because we ran RHEL guest before and we need to run windows guest this time for the planning test coverage matrix. If rhel guest is needed, please tell me.

Thanks,
Qunfang

Fix included in qemu-kvm-0.12.1.2-2.414.el6

Hi, Eduardo

Could you help check my comment 3? Because we have only one week to verify the bugs in errata, so we need to your help to estimate the test scope to avoid we are testing too many configuration and the time is not enough.

Thanks,
Qunfang

Yes, please. On each vendor, please test at least one model supporting xsave, and at least one model not supporting xsave.

The guest OS shouldn't matter, but some guests may make bugs more visible (e.g. I know Linux can use xsave. I don't know about Windows). It would be interesting to use guest-side software that actually uses xsave and run it while migrating (if you happen to already have a guest-side test case for xsave). On the other hand, considering that xsave migration was already working and the new code didn't touch the xsave section, testing using Windows guests should suffice if you are really short of time/resources.

Okay, thanks for the valuable suggestions.

Comment 11 Qunfang Zhang 2013-10-28 06:03:49 UTC

The bug following bug is verified pass on qemu-kvm-415, so I would like to verified this bug now. QE will continue test a round of stable guest abi test for sanity.

Bug 1022821  - live-migration from RHEL6.5 to RHEL6.4.z fails with "error while loading state for instance 0x0 of device 'cpu'"
