Well, chroot would pretty much do the same thing though, wouldn't it?

Nginx pretty much yes, but not YABS (aka untrusted programs/code) because it could reboot or mknod the filesystem device (I think) and manipulate/delete the data or load a kernel module.

Well, as long as root permissions are dropped before running the untrusted code there really isn't much it can do but in the end it just depends on what's the most convenient in a given situation. If it works it works

we have left openvz when it was acquired and I think we made a good decision

Why would you choose OpenVZ over LXC here? Genuine question.

LXC does not support 2nd level quotas which is required for shared hosting.
In the absence of 2nd level quotas we cannot count/limit user disk space usage.
As a VPS provider, you cannot limit spam on other virtualization types. The only way is block port 25. However, in OpenVZ you can limit spam based on spam emails.

Well, without having looked into it, i'm pretty sure that should be fixable somewhere on the filesystem level, either directly by using filesystem quotas or with some kind of clever mounting.

You have to look into it. There is no 2nd level quotas at all in LXC.
Comparing with LXC openvz is most stable and widely supported by control panels, yes, however, Openvz still have issues as opevz9 is still in beta since long.
We cannot install cPanel on LXC in a standard way, Need to do manual work at host node (https://docs.cpanel.net/knowledge-base/general-systems-administration/linux-containers/)

LXC is good for development but not suitable for web hosting environment.

I don't think it really matters what LXC does or doesn't when you can archive the desired effect at a lower level. If the filesystem disallows writing data beyond a certain amount LXC won't change that.

That's unfortunate but thinking a little bit outside the box never killed anyone

LXC is good for development but not suitable for web hosting environment.

Tendency wise i'd probably agree but i figure it's more about out of the box support and entering uncharted territory than actual technical limitations.

Just because cPanel won't run inside a non privileged container doesn't mean its not suitable for web hosting.
Webhosting runs just fine within LXC, cPanel is just to inversive.

"We strongly recommend that you use Red Hat® Enterprise Linux® (RHEL) 7 or CentOS 7 as your server’s LXC host. This configuration ensures the best compatibility with cPanel & WHM."

Ha?! Why not Ubuntu 9.04? Really liked that little fella...

It's probably one of those enterprise things dirty plebs fail to understand.

Webhosting runs just fine within LXC, cPanel is just to inversive.

Webhosting runs just fine within windows as well. You can host even using windows with a very small software but it doesnot means windows is suitable for web hosting.

Huge difference there and i hope that's pretty much obvious. I have had a very superficial look into the quota problem though. Seems all it needs is a somewhat recent kernel and an appropriate root device setup anyways. Even if it wasn't fixable (unlikely - at the very worst fuse could realize quotas pretty much no matter what) cPanel is just a panel and not webhosting as a whole.
