I don't know about that one, sorry.  IIRC I got the lxc-ssh container to
DTRT on 10.04, but it's entirely possible I was getting those dmesg
errors and not seeing them, because I wasn't on a local tty.

UPDATE: oh, I see you're just using lxc-veth for bash... I dunno
anything about that.  I guess you could be getting that when bash tries
to initialize itself (e.g. setting $HOSTNAME)?  Do you get the same
problems with /bin/dash or (say) /bin/pwd instead?

The bracketed number is the number of seconds since boot.
The message is being emitted by the kernel.

Show us your .conf.
Maybe show us some diagnostics, too

    lxc-ps auxf
    lxc-netstat --name "foo" -nlp
    netstat -nlp
    ip l
    ip a
    ip r
