Title:
  vmx_mtf_test / vmx_mtf_pdpte_test from ubuntu_kvm_unit_tests failed
  with  Expected VMX_MTF, got VMX_VMCALL.

Status in ubuntu-kernel-tests:
  New

Bug description:
  Issue found in 5.11.0-1009-kvm
  This is not a regression since the test was run with the latest hirsute-WIP branch, with upstream tip c986dbe867053 ("x86/vmx: skip error-code delivery tests for #CP").

  This is a sub test in vmx, however the instruction intercept test will
  stop the whole vmx test (lp:1931956), it will need to be blacklisted
  first with "-instruction*" in x86/unittest.cfg to let vmx test to
  finish. Test log:

  filter = -exit_monitor_from_l2_test, test = vmx_mtf_test

  Test suite: vmx_mtf_test
  PASS: MTF VM-exit after OUT. RIP: 0x4041c7 (expected 0x4041c7)
  PASS: MTF VM-exit after OUT. RIP: 0x4041cc (expected 0x4041cc)
