The Xen approach uses a OUI that is allocated to Xensource, Inc., so
it would be inappropriate to borrow that.  The LDoms team has an OUI
allocated for this purpose I believe, but I don't know how they plan
to manage it.  The Crossbow project could apply for an OUI.

For the trailing 3 bytes, Xen simply generates random numbers (0x0-0x7f
for the first byte, 0x0-0xff for the other two).  There's no attempt
to detect a clash, even on a single system.

It's very common for administrators to specify the MAC address to use,
which means that the problem of managing the address space moves
elsewhere, obviously.
