[Bug 1340836] [NEW] [juju/lxc] juju local deploy on kvm machine using lxc failed with error: error executing "lxc-start"

[Manoj Iyer]

Public bug reported:

Deploying a (mysql) service on a KVM instance using juju local lxc fails
in lxc-start.

 agent-state-info: '(error: error executing "lxc-start": The container fa
iled  to start.; To get more details, run the container in foreground mode.;
Additional  information can be obtained by setting the --logfile and --log-priority options.)'

Here are the steps to reproduce:

* juju switch local
* juju bootstrap
* juju set-constraints mem=2G
* juju add-machine

* (OPTIONAL) ssh to machine and modify network setting, this is because
we want to keep the ip address of the service the same as the ip that
was assigned to the kvm instance. You can skip this part and you will
see the same failure.

* juju ssh 2

sudo rm /etc/network/interfaces.d/eth0.cfg
sudo vi  /etc/network/interfaces.d/lxcbr0.cfg
-------------- lxcbr0.cfg -------------------
auto eth0
iface eth0 inet manual

auto lxcbr0
iface lxcbr0 inet dhcp
    bridge_ports eth0
--------------------------------------------------

* juju deploy mysql --lxc:2
