In the following block, you start saying 3e, but finish the rest with 36. Also, should there be a rhev mac generator added in? 00-1A-4A def randomMAC(type = "xen"): """Generate a random MAC address. 00-16-3E allocated to xensource 54-52-00 used by qemu/kvm The OUI list is available at http://standards.ieee.org/regauth/oui/oui.txt.

Thanks for the report, fixed upstream: http://hg.fedorahosted.org/hg/python-virtinst/rev/0bbec7372924 As far as virtinst is concerned, RHEV == KVM, so we wouldn't use anything other than the default qemu/kvm prefix.
Fixed in python-virtinst-0.400.3-12.el5
You can test by creating a xen guest via virt-install and checking the MAC address we randomly generate (will be in the --debug output). It should now be starting with 00:16:3E when previously it started with 00:16:36

Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: There was a typo in the randomMAC method for the Xen utility defined in the util.py file. The randomly generated MAC addresses incorrectly started with the prefix 00:16:36. This could have caused some tools depending on the expected MAC prefix to not work with guests created by the virt-install tool. This has been fixed and the MAC addresses now correctly start with the prefix 00:16:3E.
