Issue found after kvm-unit-test repo updated to d8a4f9e5 (ci: Update the list of tests that we run in the Fedora Cirrus-CI),
This debug test failure is slightly different from the debug failure in 3.13 / 4.4 (bug 1821906)

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.

This looks like a HW-dependent issue, node gonzo with B-4.15 is not failing with this test. |
