[gentoo-user] LXD

[gentoo-user] LXD

[john]

Hi,

I have set up some containers with LXD which have been running fine up
to about a week ago.

cgmanager no longer works as it crashes out and when I connect to
containers:-

systemctl
Failed to connect to bus: No such file or directory

which also causes network to fail.

My belief is that lxd now relies on systemd to do the cgmanager part.
I don't want to install systemd as this is a Gentoo box.

Can anyone see a way round this or a config option which may help.

John

cgmanager was an Ubuntu project and it was abandoned when Ubuntu chose
to migrate to systemd [1]. The README on [2] says "Please note that
the CGManager project has been deprecated in favor of using the
kernel's CGroup Namespace or lxcfs' simulated cgroupfs." I don't know
what the "in favor of" means or how to take advantage of those two
options, but maybe there's a solution in there.

Thanks Tom,
I have got my containers up and running again. Before when I was using
lxd it was assigning an ip address to the container so I could connect
to outside world. After recent changes this stopped and i believe it was
down to systemd not running in the container (it was before). I now
realised that you could assign a static ip address using lxc exec
command.
