    struggle with new 5.3 LXC "features"

    5.3 and unprivileged containers: docker works, mount nfs does not

    I upgraded from 5.2 to 5.3 and am trying to re-deploy self service unprivileged containers where users create an LXC container and then can do whatever they need to do (mostly installing docker, mounting file systems etc) First I am disabling all the magic hacks that were required to run docker...

    Cannot change LXC Features (nesting, nfs) as PVEAdmin

    I give users the role PVEAdmin for their pool to do self service. Now that there are Features for container nesting and nfs I would like to allow them change that. Unfortunatelty the PVE admin role does not seem to have permissions to change this. Is there a way to enable this globally ? I used...

    prox: tool to rapidly deploy LXC containers via REST API

    if anyone finds this useful: This tool allows you to deploy and manage many LXC containers very quickly. It requires a mechanism for dynamic dns with your virtual appliance. https://pypi.python.org/pypi/proxmox-tools issue tracker: https://github.com/FredHutch/proxmox-tools/issues

    maximum number users?

    Hi, I am trying to add about 2500 users (looping over a text file and executing pveum each time ) and at some point pveum reports that user.cfg is too large. Is there any specific size limitation or max number of users that I have to consider? Thanks D.

    LXC roadmap ?

    Being reasonably happy with a newly installed 4.1 cluster I'd be interested what the plans and priorities are for LXC for the next PVE release. We don't seem to have the issues others reported (e.g. snapshots / backups ---- we use local ZFS) and saw only one smallish bug so far...

    running docker inside LXC

    our developers and researchers need docker (they collaborate using images from dockerhub). We can configure proxmox to allow for deployment of self service KVM images which works well ....but it still seems silly because the performance of containers is much better and they use fewer resources...

    CentOS and Ubuntu LTS not really supported

    OpenVZ seems like a great concept but if you install the CentOS and Ubuntu appliances they don't work out of the Box. This is quite de-motivating to new users who want to try out the concept. I see that Debian is fully supported but many users won't understand that that means the other won't...
