Public bug reported:
Hello,
I've a test KVM guest with hostname 'lxdhost'. Latest Ubuntu 14.04 is on
lxdhost with 3.13.0-85-generic kernel. I give 2 GiB RAM and 2 vCPU core
to this host. When I create a Trusty container and set up resource
limits, these do not apply to the container.
ubuntu@lxdhost:~$ lsb_release -a
No LSB modules are available.

I tried with linux-generic-lts-xenial kernel (4.4.0-22-generic), but
does not solve issue.
Thank you!
