You might also want to see what our code checks, see e.g. [1],
which is part of ovirt-host-deploy and is used also by
ovirt-hosted-engine-setup.

If you want to use it directly, you can do something like:

# yum install ovirt-host-deploy
# python -c 'from ovirt_host_deploy import hardware; v =
hardware.Virtualization(); print "OK" if
v.detect()==v.DETECT_RESULT_SUPPORTED else "Not OK"'
