Any chance you can run 'git bisect' to find the offending patch? Or just try reverting a few, you can ignore the ppc ones, so that only leaves you 7 different commits.
Does this same test pass in 5.3-rc1?
Yes. same test pass on 5.3-rc1 kvm unit test always fetching master branch and at tip runs the latest test code on all branches mainline 5.3-rc1 and stable-rc-5.2 branch
Anders, are you running the same kvm-unit-tests commit that passed for 5.2.2? My suspicion is that your previous test didn't have this commit
No. I see two extra test code commits for 5.2.3 Re-tested 5.2.2 with tip of kvm unit tests sources and vmx test FAILED [1].
Greg, This investigation confirms it is a new test code failure on stable-rc 5.2.3
No, it only confirms that kvm-unit-tests/master fails on 5.2.*. To confirm a new failure in 5.2.3 you would need to show a test that passes on 5.2.2 and fails on 5.2.3.
As Paolo suspected, kvm-unit-tests/master fails on 5.2.* and passes if commit 95d6d2c ("nVMX: Test Host Segment Registers and Descriptor Tables on vmentry of nested guests") is reverted (from kvm-unit-tests).
The failures are quite clearly in the new test(s).
