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

https://en.wikipedia.org/wiki/MAC_address#Universal_vs._local

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,
