Can't create LXC container: "unable to detect OS distribution"

[joshuapl]

Hello,

I tried to create an LXC container, based on my own template - actually, it is based on a custom Linux distribution named "PLD Linux".

I checked how a template should look like, what files seem to be required etc.
Finally, I've gone through the creation procedure and... almost succeeded.
Unfortunately, at the end I get:

extracting archive '/var/lib/vz/template/cache/pld-mailhoar_amd64.tar.gz'
Total bytes read: 3411630080 (3.2GiB, 134MiB/s)
Detected container architecture: amd64
unknown ID 'pld' in /etc/os-release file, trying fallback detection
unable to create CT 103 - unable to detect OS distribution

Indeed, in /etc/os-release I have:
ID="pld"

I wanted to find out if there is a list of allowed IDs, and found that there is a directory /usr/share/lxc/config with various distros files, like
debian.common.conf
debian.userns.conf

Files *.userns.conf seem to be identical, so I created pld.userns.conf like all other files
For pld.common.conf I tried some simple settings:

# =============================================
# Distribution configuration
lxc.include = /usr/share/lxc/config/common.conf
lxc.arch = linux64

# Container specific configuration
lxc.rootfs.path = dir:/srv/pld/x86_64
lxc.uts.name = builder-x86_64

# Network configuration
lxc.net.0.type = veth
lxc.net.0.link = lxcbr0
lxc.net.0.flags = up
lxc.net.0.hwaddr = 00:16:3e:71:5e:81

lxc.pty.max = 100
lxc.start.auto = 1

lxc.mount.entry = none dev/shm tmpfs rw,nosuid,nodev,create=dir
# ============================================

All done, saved.
However - when I try to create CT, the result is exactly the same:

unknown ID 'pld' in /etc/os-release file, trying fallback detection
TASK ERROR: unable to create CT 103 - unable to detect OS distribution

Any ideas what I'm doing wrong?
Is there some other file where all valid IDs are listed or something?

Best regards,

Jacek

You can find the respective detection in our git repo [1] - hope that helps!

Thanks, that clarified a lot! I changed the id to "unmanaged" and went a little bit further (at least managed to have the subsystem running), although the networking is not functioning. I'll try to find out what's going on.
