Sometimes the container needs to be fully stopped, and started again for the

I tried a number of scenario, including restarting the container after
adding the device to it.

Can you post the logs? There should be a dump.log in the directory you
chose to put the images in. The LXC log may also be instructive.

2016-09-08 Thread Nicola Volpini

Thank you all for the tips.

I wasn't aware Ansible introduced the lxd module. I knew they were
working on it, good to know!
It is not a full lifecycle solution but probably better than nothing.
I'd love to see this integrated into Foreman, eventually.

Without knowing what ./tests/testsuite actually do, it's hard to tell. It's
possibly that the code is doing something not available in lxc/lxd (e.g.
loading kernel module), and doesn't handle failure correctly (e.g. keep
waiting instead of saying fail).

A workaround is to edit your SRPM (or possible the makefile, by creating an
additional patch), and comment-out the test code (there should be "make
check" or "make test" somehwere)

Re: [lxc-users] Has anyone ever configured or used LPVS with LXD/LXC before?

2016-09-08 Thread Fajar A. Nugraha

I've used IPVS (with keepalived, which also includes vrrp feature) in the
past with xen. As long as you use bridge networking, with the server's eth
(or vlan) as slave (NOT using lxdbr0, cause it wouldn't make much sense to
loadbalance two or more containers on the same host), I don't see how it
will be any different with lxd.
