Enables the Fake QEMU support, used mainly for testing - to run vdsm on virtual machines that do not have VT/AMD-V extensions.
This requires a setting in /etc/vdsm/vdsm.conf
fake_kvm_support = True
ovirt-host-deploy should be told not to overwrite this setting. See ovirt-host-deploy README on how to do that.
No requirement for a custom property
