ubuntu_kvm_unit_tests: vmx_cr_load_test: VM-Fail on vmresume: error number is 8

[Stefan Bader]

On host spitfire running focal:linux (5.4) lowlatency for sru-20210816:

DEBUG| [stdout] Test suite: vmx_cr_load_test
DEBUG| [stdout] VM-Fail on vmresume: error number is 8. See Intel 30.4.
DEBUG| [stdout] FAIL vmx

Might not be limited to the lowlatency flavour as spitfire was not selected for generic. This host is also the only one to show this failure.

Interesting, I found this bug https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1936380 you filed last month, before the recent test case change. I think this is something that I need to pull out from vmx again.

I wonder what Intel 30.4 is.

[Po-Hsu Lin (cypressyew)]

Tested with Intel node spitfire and vought, it seems that only spitfire is affected. Pull this test out can make vmx test finish properly. This test case change will be handled in bug 1941830)

kvm-unit-tests source tree updated https://kernel.ubuntu.com/git/ubuntu/kvm-unit-tests/commit/?h=hirsute&id=1593e88af6f925f44df5089ebdfb7549e1cba722

Test retriggered on spitfire, will update the bug title later.

Found with focal/linux-hwe 5.4.0-89.100~18.04.1 lowlatency on spitfire.
