vmx_init_signal_test in ubuntu_kvm_unit_tests fails on bionic/linux amd64 (FAIL: INIT signal blocked when CPU in VMX operation)

[Kleber Sacilotto de Souza]

Issue found on node akis, with bionic/linux 4.15.0-150.155. This is not a regression as the failure can be found on previous releases.

Error:
filter = vmx_init_signal_test, test = vmx_init_signal_test

Test suite: vmx_init_signal_test
FAIL: INIT signal blocked when CPU in VMX operation
filter = vmx_init_signal_test, test = vmx_sipi_signal_test

[Po-Hsu Lin (cypressyew)]

Un-dupe this as the error seems to be different from the one we saw on node kili.

With kvm-unit-test repo updated to d8a4f9e5 (ci: Update the list of tests that we run in the Fedora Cirrus-CI), this test is still failing with the same error message.
