vmx_host_state_area test from ubuntu_kvm_unit_tests crashed with Eoan Azure

[Po-Hsu Lin]

Only Standard_F32s_v2 and Standard_D48_v3 can be tested with KVM unit test.

And it looks like the kvm_unit_test will crash with vmx_host_state_area:

If you run this test manually on those nodes, the instance will stop responding (and nothing will be printed in syslog).

(crashed even earlier here)

This issue a bit hard to spot, as these 2 are the only instances that supports KVM unit test and the test will be interrupted instead of marking as failed, you will have to review the jenkins test report directly to see this.

From the test log it looks like this can be found since 5.3.0-1017.18 (no earlier test report available)

We would need access to the console for debugging this.
