Well, I will probably take over an existing Ubuntu 16.04 server, which has lxc and lxd installed. Since there is no really working backupsolution gor lxc / lxd, i am wondering whether i can install cloudmin on top of that. Ubuntu16.04 is running under ZFS, btw.
Do you see any issues? Can i, after installation and setup of cloudmin administer the existing container and replicate/backup them? I do not want to break everything :-)
Thanks and best

Yes, you can install Cloudmin and import the existing LXC containers into Cloudmin's control.

I have an out of the box LXD/LXC/ZFS setup, cloudmin runs on the host machine (ub1604), no extra software. Cloudmin recognizes lxdbr0, finds other physical machines on the network and even sees the used bridged IPs but doesn't find any lxc instance. Is there any known trick that I could apply to register my containers? Thanks and best

Did you try to import them into Cloudmin using the page at Add System -> Add LXC Instance?

sure I did. No ssh since there is none, the right webmin port although there isn't any, the right container name - no luck. But the lxd documentation says somewhere: don't mix lxd lxc with standard lxc.

What error message did you get exactly? Were you even able to select the LXC container on the Add LXC Container page?

No error message. cloudmin said: 0 container found. Tried every option which i could google and even changed the standard directory from lcx to lxd. No avail

Ok, it looks like the version of LXC that you're using there is quite different to what Cloudmin expects. I think we'd need to do some work to support LXD properly - right now, only plain LXC is supported.

i think ZFS is not fully supported, is it?
Submitted by JamieCameron on Thu, 09/22/2016 - 22:33 Comment #13
No, there's no support in Cloudmin for ZFS.
