Dear Jon,

at the given link, right at the last sentence of the paragraph, you'll find:

> It's recommended to use a MAC address inside the range 00:16:3e:xx:xx:xx. This address range is reserved for use by Xen.


You see, there's no only the reserved prefix 00:50:C2, but there is at least one more official MAC space 00:16:3e reserved by Xen. Why do you don't use this and follow my simple or advanced suggestions

	macaddr=$(echo -n "00:50:C2"; hexdump -n 3 -v -e '/1 ":%02X"' /dev/urandom)

	macaddr=$(echo -n "00:50:C2"; echo "${hostname:0:1}${hostname: -2} $(head -c 3 /dev/urandom) " | hexdump -n 3 -v -e '/1 ":%02X"')

Of corse, the prefix may be replaced by any of this appropriate Prefixes. Probably just Daniel will know, if there is already a MAC space requested by the LXC project.
