For each lxc.network.type = veth, if you DON'T specify an
lxc.network.hwaddr, you get one assigned at random (example below).
Are these assignments made from a reserved range (a la 169.254/16 in
IPv4), or are they randomized across the entire address space? AFAICT,
it MUST be the latter.
Further, when manually allocating a static hwaddr (so I can map it to an
IP within the DHCP server), is there any particular range I should avoid
or stick to?
For example, it wouldn't surprise me if some hardware/software did
things like "hmm, your MAC indicates you're from <vendor>, and I know
<vendor> doesn't implement jumbo frames correctly, so I won't send you
any" -- which could result in bizarro issues because my container isn't
actually a <vendor> NIC.
