It uses systemd-detect-virt to check for VM environment, and bails out the test with:
 if (tst_is_virt(VIRT_XEN) || tst_is_virt(VIRT_KVM))
  tst_brkm(TCONF, NULL, "This testcase is not supported on this"
          " virtual machine.");

Looks like the test will be skipped from Bionic Azure test result.
But this tool is not available for Trusty and this test failed.
