If you pick MAC addresses for your VMs, just make sure they are locally
administered ones. See


These have the second least significant bit of the first byte set to
one, so starting with 04 is NG. First byte values matching 0x#2, 0x#3,
0x#6, 0x#7, 0x#a, 0x#b, 0x#e and 0x#f, where # stands for an arbitrary
hexdigit, are fine.

Hope this helps,
