[libvirt-users] How can a user process be automatically started after the container is started?

[WANG Cheng D]

Dear Daniel,

You said "use a real init system like systemd to spawn off the things", do you mean a full OS distro container?

I installed the container using "yum --installroot=/root/fedora19lxc --releasever=19 install -y openssh, bridge-utils" which is described at https://www.redhat.com/archives/libvirt-users/2013-August/msg00007.html.

I don't know how to make systemd work in my current container. And I don't know how to install a full OS distro container either. Could you give me more guidance?

With my warmest regards,
Cheng

Whatever you specify as the <init>....</init> binary in the container XML file is started when the container is created. If you only want
1 application to run, then this is straightforward. If you want to run multiple applications either point the "init" binary to a shell script to run the many things, or better yet use a real init system like systemd to spawn off the things you need.

Daniel
