Ok, I remove the mirror when submit job, but things same. 

BTW, I see this, http://git.linaro.org/lava/lava-lxc-mocker.git/tree/lxc-create

it will not use release or mirror, it just a simulate, so I guess the issue not related with what you said I afraid. I not use lxc in fact, But lxc mocker...

I use lxc-mocker in docker container, everything is ok.

Just if the package did not install in advance, then next command will hang in
web:

lxc-create -t ubuntu -n test_lava -- --release xenial --mirror http://
mirror.bytemark.co.uk/debian --packages systemd,systemd-sysv --arch amd64

I've not tried to directly reproduce your problem, but this command
line looks suspect. You're telling lxc-create to make an Ubuntu image
(with Xenial) but you're pointing it at a Debian mirror. I would never
expect that to work. What are you trying to do?


Cheers,
