Re: [Xen-users] mac addresses domUs

AFAIK every NIC manaufacturer is allocated a 2 (or is it 3?) byte prefix for

guidelines on what macs
to assign to domU devices? Or is this even something that one needs to
consider?
Mike, the Users Manual (located at
http://www.cl.cam.ac.uk/Research/SRG/netos/xen/readmes/user/user.html )
says the following:
"You may also want to edit the vif variable in order to choose the MAC
address of the virtual ethernet interface yourself. For example:
vif = ['mac=00:16:3E:F6:BB:B3']
If you do not set this variable, xend will automatically generate a
random MAC address from the range 00:16:3E:xx:xx:xx, assigned by IEEE to
XenSource as an OUI (organizationally unique identifier). XenSource Inc.
gives permission for anyone to use addresses randomly allocated from
this range for use by their Xen domains."

UNIX was not designed to stop you from doing stupid things, because that
would also stop you from doing clever things.
