Doc Text:
The use of multicast MAC addresses is not supported by libvirt. Previously, the hosted engine deployment wizard was not verifying the validity of a provided MAC address and the wizard was failing with an unexpected error. Now, MAC addresses are verified and the user is prompted to enter the address again if it is not valid.

Comment 2 Jiri Moskovcak 2014-07-07 10:55:10 UTC 
As it turned out, I made a typo when entering a mac address and entered multicast mac. As it seems libvirt doesn't allow multicast mac address which lead to this error. So I think the right place to fix this is in the setup and prevent user from entering wrong mac. This [1] is the commit in libvirt which adds the check, so you can use the same pattern to validate the mac in the setup.

Verified in ovirt-hosted-engine-setup-1.2.1-3.el6ev.noarch

You may specify a unicast MAC address for the VM or accept a randomly generated default [00:16:3e:02:ef:e0]: 01:1A:4C:10:3F:11
[ ERROR ] Invalid unicast MAC address specified: '01:1A:4C:10:3F:11'
