With containers I might not need nearly as much RAM

LXC or LXD?
LXD is an LXC interface.
Ubuntu is working on live migration with LXD. That will be awesome.

That will be awesome! How do you backup containers?

Just tar the container folder. You can also do file level backups of the containers. LXC by default stores everything in
/var/lib/lxc/so if you want to restore a file tocontainer1you could just cp it back to/var/lib/lxc/container1/root/pathtofolder/ -
@johnhooks Can I do that with the containers running?
-
Can I run different Distros in containers or just the same as the host?

Which file level restore or using tar?

You can run different distros. But I think you need to match systemd and init between host and container though.
-
@johnhooks tar. I assume rsync would work too?

I think you have to stop the container to do that. Ya rsync works also.

How would check that? I am a huge CentOS7 fan

@johnhooks should be super easy to write a script to stop containers, tar them and start them again.

I know Ubuntu 15.10 is systemd, CentOS 7 is also systemd. So if you run a CentOS 7 host you can run Ubuntu 15.10 containers (what I'm doing for my XO container).

ya. I use Ansible, but you can script it also.

I will be using Ubuntu as the host. CentOS7 as the guest

You could always start with CentOS 7 for containers rather than building them on Ubuntu.
