There are two issues here. One is that currently the CLI doesn't work
correctly with parameters that start with a number, as the lexer splits
it into a number and a word, and then it thinks that there are two
parameters instead of one. We have a bug (a RHEV bug, it it affects
oVirt as well) for that already:

  https://bugzilla.redhat.com/show_bug.cgi?id=1110366

You can workaround this using quotes, either simple or double.

The other issue is that you are probably a *multicast* MAC address. That
is what the server is actually checking, not just that it is
syntactically correct. This basically means that the eight bit can't be
1, as that is what indicates multicast. Just make sure that you use a
MAC address whose second character isn't an odd number. For example,
this will fail:

  # add nic --vm-identifier ov31 --network-name backend --name eth4
--mac-address '01:01:01:01:01:01'

But this will succeed:

  # add nic --vm-identifier ov31 --network-name backend --name eth4
--mac-address '00:01:01:01:01:01'

The error message could be better. You may want to open a bug requesting
an improvement.
