Just as a point of reference it doesn't auto insert the mac address
for me either and generated mac address doesn't seem to follow the
default format. I may be doing something wrong though. My test
involves creating an unprivileged container using the default
template.
Note: My creation command is prefixed by "TMPDIR=/tmp" as it works
around the default secure tmpdir on my installation. I've just never
been bothered to remove the module since it doesn't affect 99% of what
I do. Just redefines TMPDIR as /tmp for the purpose of the script.
Command used: TMPDIR=/tmp lxc-create -t download -n testcont
Container created: Ubuntu Trusty amd64
Result: No default hwaddr defined in the configuration.
I then did a test privileged container and found that used the
lxc-ubuntu template instead. It also had the hwaddr entry everyone
was expecting. I checked the script and there is a line that
explicitly adds it. This isn't present in lxc-download at all.
# if there is exactly one veth network entry, make sure it has an
# associated hwaddr.
nics=`grep -e '^lxc\.network\.type[ \t]*=[ \t]*veth' $path/config | wc -l`
if [ $nics -eq 1 ]; then
grep -q "^lxc.network.hwaddr" $path/config || sed -i -e
"/^lxc\.network\.type[ \t]*=[ \t]*veth/a lxc.network.hwaddr =
00:16:3e:$(openssl rand -hex 3| sed 's/\(..\)/\1:/g; s/.$//')"
$path/config
fi
