The virt-what command that is used in the function runnng_in_vm() in test-framework.sh only exists in RHEL, not in SLES. This makes the behavior of any test that uses this function unpredictable on anything but RHEL distros.

The running_in_vm() function was added in http://review.whamcloud.com/20698, part of the fix for LU-8248.
