Can you set the macaddr on your virtualbox nic to something
lower, like something starting with 22: ?

32: sounds really low for a veth peer nic, I'm surprised - mine are
always fe:.  In fact, looking at
src/lxc/conf.c:setup_private_host_hw_addr(), it makes sure to set
0xfe in the first two bytes.  So why are you getting 32: ?  Hmmm.

Could you also try adding '-l info -o lxc.debug' to your lxc-start
command on a failing container, and send the resulting lxc.debug
file?  We're looking for output from:

        DEBUG("mac address of host interface '%s' changed to private "
	              "%02x:%02x:%02x:%02x:%02x:%02x", veth1,
