LXC support for openmediavault-kvm plugin

ryecoaaron · 16. November 2022

That doesn't really help either. I guess you would run the command it is trying as root for a better message:

wget -O- https://images.linuxcontainers.org/images/ubuntu/kinetic/amd64/default/20221115_07:43/rootfs.tar.xz | tar xJ -C /srv/dev-disk-by-uuid-76f4ccf2-ad92-4313-ba2e-259476a90313/lxc/

antsh · 16. November 2022

This is what it returns:

Code

Wow. Your system must not have xz-utils installed. What is the output of:

dpkg -l | grep xz-utils

sudo apt-get install xz-utils

How did you install your system?

antsh · 16. November 2022

That package is indeed missing. This is a vanilla omv6 install, that is very recent (within the last month).

This is a vanilla omv6 install

From the OMV 6 iso?

antsh · 16. November 2022

Yup. I have run apt autoremove at some point, so might have nuked a few packages.

antsh · 16. November 2022

Getting closer, now just getting a 504 timeout after clicking save. I can see that the tar is being decompressed into the destination, and the wget and tar processes are still running after the timeout.

slow system and/or slow internet connection?

prune will do that. docker image prune will probably do a better job cleaning up than a user would.

Thank you very much for your improvement. Today, I received the update of the Compose plug-in and saw the new functions I hope to see. Thank you very much.

Hi there! It's great LXC containers support in kvm plugin! But i have a problem when i try to start container.

"Unable to - poweronошибка службы: GDBus.Error:org.freedesktop.machine1.NoMachineForPID: PID 1231195 does not belong to any known machine

OMV\Exception: Unable to - poweronошибка службы: GDBus.Error:org.freedesktop.machine1.NoMachineForPID: PID 1231195 does not belong to any known machine in /usr/share/openmediavault/engined/rpc/kvm.inc:2180

Stack trace:

What i miss when i create an LXC container?

NoMachineForPID: PID 1231195 does not belong to any known machine - cant understand why there no any machines belong to PID

Did you enable cgroup v1? It isn't enabled by default for debian or proxmox kernels.

Did you enable cgroup v1? It isn't enabled by default for debian or proxmox kernels.

Yeap, i used 3CX docker container and need this. but now i dint use 3CX in docker so i can disable cgroup v1. It helps me?

...but cant find how i can disable v1.

i enabled it by using this:

Code

echo 'GRUB_CMDLINE_LINUX=systemd.unified_cgroup_hierarchy=false' > /etc/default/grub.d/cgroup.cfg

update-grub

Could you tell me how to disable v1?

Thank you very much!

ALEXSANPEDRO · 22. November 2022

Code

echo 'GRUB_CMDLINE_LINUX=systemd.unified_cgroup_hierarchy=true' > /etc/default/grub.d/cgroup.cfg

update-grub


it true to disable v1?

The opposite way you enabled it? Never enabled or disabled it myself. I would have to google for it.
