lxc

I just noticed that in the default configuration of newly created LXC container, the TTY count defaults to 2. I changed it to 1 and nothing bad happens :p. Using web console and pct enter simultaneously doesn't break either. Just curious why it defaults to 2, I thought there might be a reason.

Strange question, and honestly not a big deal, but just got me wondering. When I do an nslookup or a ping -a xxx.xxx.xxx.xxx, my plex LXC doesn't return a hostname. My router shows its name as UNKNOWN (where other IPs would show a hostname), even though I've confirmed the hostname within the...

Hi I'm having a zfs pool RAIDZ1, which includes 4 x 10TB disk. When using this pool in a file server (SMB and NFS) for different purposes, which is better way to share it in LXC or in VM: mount the whole pool as a one big disk (mp1), and use directory structure to share the resource, like...

Hello All! I have been experiencing some LXC with small memory allocation stops, randomly dies silently without any trace of cause. Watching over time, I found that the most probably reason is out of memory. Allocating more memory allows it to run longer, but it fails anyway. When I try to find...

Hey everyone, I'm having fileystem permission issues with LXC in Proxmox VE, 8.3.3, which I know has been discussed to death. I've read a lot of the threads, tried a bunch of the suggested solutions, and I'm still facing the same issue. Scenario I have a Proxmox VE 8.3.3 machine, and I've...

Hey everyone, I'm trying to set up an SMB mount in an unprivileged LXC container on Proxmox, but I’m struggling to understand how UID and GID work in this context. I've read multiple guides, including this one: Proxmox: Bind SMB Mount to Unprivileged LXC Container the Easy Way, and searched...

After a recent Proxmox update, my LXC container (ID 109, running Plex) fails to start. I attempted to restore from a backup, but the issue persists. Below are the debug logs: lxc-start: 109: ../src/lxc/sync.c: sync_wait: 34 An error occurred in another process (expected sequence number 7)...

First, I want to just hands up state that my setup is very much unsupported, I know that. But I have been playing with getting proxmox running on the Oracle Free tier ampere server and that works just swell. I want to play with it to see if I can get it running reliably on OCI, with a IPsec...

Good day all, Short description of the issue: inability to start containers consistently. Context in which the problem arose: 7-node cluster recently upgraded from version 7 to 8 (I believe the issue did not occur before the upgrade); no PVE subscription. Scope: All the containers (three in...

Hi community, I am trying to set up Gluetun to be used with my Surfshark VPN so I can use it as with Prowlarr. I'm following these guides in order: https://pve.proxmox.com/wiki/OpenVPN_in_LXC https://github.com/qdm12/gluetun/discussions/1482 I know I could run this as a docker container but...

I have a NAS (truenas scale) set up with an SMB shared directory called Backups. I added the SMB share to PVE using the web GUI. I also have Proxmox Backup Server running as an LXC in PVE. I created a bind mount to get the share to the LXC. So far everything is working and I can access the...

Hello, I've installed Debian 12 turnkey Linux with Postgresql 18.1 from the repository, but the PostgreSQL version is 15.1 and Debian 15.10. Is the image bad? Or what am I doing wrong? Thank you. EDIT: I've upgraded to version 17.2 and its working..Its just for test purpuses. Regards

I have this single node Proxmox and recently it froze out of the blue. I could not access its web interface or SSH into it. I ended up having to hard reset it. After the reboot, I went to the logs to try to make some sense of it, and found a bunch of "pveproxy" messages. Jan 22 20:21:05...

I've tried upgrading a Fedora LXC from v40 to v41, but it fails to start, or rather it starts but does nothing. The Proxmox host is updated in full, so should be the latest-and-greatest as of writing. Anyone else seeing this, or can point at what's going wrong? root@pve:~# pveversion...

hi guys, i have moved a vol of a lxc (working good) to larger disk. i still have subvol-10*-disc-0 (the good target) but also subvol-10*-disc-1 which is taking too much space. on ZFS when i enter to subvol-10*-disc-0 all is good but the subvol-10*-disc-1 is empty. I can't remove the...

hi I plan to install some internet facing services on LXC, and I 'm reviewing the security. The scenario is the worst case: the attacker has RCE with root privileges on the LXC. will he be contained there? The LXC is of course unprivileged. I'm not considering any 0days of the kernel/OS...

Hello I have no idea what happened, but my LXCs are no longer getting any IP addresses. My VMs are getting IPs just fine and are fully online, its just the LXCs. I have a Unifi UDM as my DHCP server. Here is my hosts /etc/network/interfaces root@rdu-pve01:~# cat /etc/network/interfaces #...

Hello all, I am a newbie in the Proxmox world or with VMs generally (and Linux generally), and would like to know if there are some advices to follow now before setting all in a wrong way. Here is my project with an old laptop as server (8 GB RAM, dual core): MQTT, Zigbee2MQTT and HA...
