I used to run docker in a VM, but was tempted to move it to a CT after seeing a number of Youtube videos about it. Actually the saving in resources are incredible: I run 15 containers and docker in 1 GB RAM whereas in a VM I'd use more than 2 GB. I understand there are some small security...

It's a headless server, there is no GPU. I don't need to play games on it, it's only for the windowing environment.

Trying to run ghcr.io/linuxserver/wireguard in docker in a CT, I get the error "apply caps: operation not permitted". Seems to have something to do with CAP_MKNOD capability in CT. I found a couple of refences to it in LXC, but nothing specific for Proxmox. Anyone know how to fix?

# smartctl -i -n idle /dev/sdg smartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.4.106-1-pve] (local build) Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org Device is in IDLE_A mode, exit(2) # smartctl reports the drive is WDC WD80EDAZ-11TA3A0. I don't really have...

I have the same problem. I have only one volume with the CT, and it's not mounted. # pct destroy 250 zfs error: cannot destroy 'poolz/vmdata/subvol-250-disk-0': dataset is busy # zfs list -r -o name,mountpoint,mounted | grep subvol-250 poolz/vmdata/subvol-250-disk-0...

No, I don't use PBS. # smartctl -i -n standby /dev/sdg | grep '^Power mode' Power mode was: IDLE_A # It's still spinning though ...

I use an USB drive for backups, and in the nature of backups of course it only needs to spin during the backup. It seems to spin all the time though, judging by the sound. The dstat command shows zeroes for read/writes for several minutes (as long as I watched it) except for a 20/22k block when...

Yes, keyctl if it's unprivileged. IIRC, USERID remapping became too complicated with unprivileged containers and bind mounts so I skipped that. It's only a homelab with me as the only login user anyway.

I run docker in a Debian LXC container. That runs fine. I had to set options -> features -> nesting on for it to work though, but I also used bind mounts so not sure if that is related to your problem.

Is it possible to install gnome40 in a proxmox container? Like explained here https://www.addictivetips.com/ubuntu-linux-tips/how-to-install-gnome-40-on-linux-early/ I've never installed Linux GUI servers on Proxmox and actually have very little experience with Linux GUI environments (I always...

Is the question not clear, or nobody knows?

If I understand correct it is not possible to encrypt an existing dataset? What other options are there to change a vm on an unencrypted dataset to encrypted? Is it possible to create an encrypted dataset and copy the vm disk - without down time? Maybe by using snapshots?

Ahh, now I think I understand. So i'ts actually 'x from-id-in-container to-id-in-host number-of-id's' I kinda understood it as 'x from-id-in-container to-id-in-container number-of-id's' -- if that makes sense. So, I want 111 and 1000-1009 (10 id's ;)) to link between container and host...

Hehe. At least I was not the only one to fall in that trap ;)

Actually no, that gave the same error I got before. From PVE GUI: "Error: startup for container '251' failed. In /var/log/lxc/lxc-monitord.log: lxc-monitord 20210222231915.892 INFO lxc_monitord - cmd/lxc_monitord.c:lxc_monitord_sock_accept:213 - Accepted client file descriptor 7. Number...

Awesome, exactly what I was looking for !

Yes, the sub*id should be ok: root:100000:65536 root:1000:10 root:111:1 The content look wrong - you mean the mapping details? Wrong in what way? How would the look to be right? I simply need to patch through UID's 111, 1000-1010 I have done it in the way of the example on...

So, next step - I need to link UID 111 and 10 UID's in the range 1000-1910 I'm trying this, but it causes the CT to not start .... and no info anywhere about what is wrong with it.... lxc.idmap: u 0 100000 111 lxc.idmap: g 0 100000 111 lxc.idmap: u 111 111 1 lxc.idmap: g 111 111 1 lxc.idmap: u...

Sharing disks in containers using bind mounts are easy and effective, but as far as I'm informed, not possible with VM's. So what is the best way to get this functionality to VM's? I've not been able to get an nfs server working on the PVE hypervisor so my work around is having a privileged...

After much trial and error, and trying to read the corresponding parts of https://pve.proxmox.com/wiki/Unprivileged_LXC_containers I came here and found this to be correct. As the previous user I'd been trying with UID 1000, and got similar errors as above. Changed to 1005 and suddenly it...
