Proxmox GUI webpage stuck on loading

by

Connection time out!!!! So boring nah?

I can’t figure out where the problem is. It works and then couple of hours later I’d come back and it keeps on loading forever. SSH works fine, can SSH into containers as well. Just the GUI doesn’t work. Tried full upgrade. Checked for network conflicts, doesn’t seem to be any.

Here’s the tidbit solution to this probelm like similar (BTW works on PVE 6/7 version apparent)-

If browser refresh doesn’t work, then please post the output:

apt update
apt full-upgrade
pveversion -v

Then Run

apt install --reinstall pve-manager proxmox-widget-toolkit
systemctl restart pveproxy pvestatd pvedaemon
systemctl daemon-reload

by

0

In this guide, we will cover a step-by-step installation of Proxmox VE 7 virtualization software on Debian 11 (Bullseye) Linux system. It’s recommended to deploy Proxmox VE server from a Bare-metal_ISO_Installer, but it’s sometimes inevitable to deploy it on a running instance of Debian 11 (Bullseye) server.

Setup Pre-requisites

For the installation of Proxmox VE 7 on Debian 11 (Bullseye), you need the following requirements to be met;

  • A running instance of Debian Bullseye
  • A 64-bit processor with support for the Intel 64 or AMD64 CPU extensions.
  • Access to Debian server terminal as root or standard user with sudo
  • Server needs internet access
  • Enough hardware resources to be used in Virtualizing other operating systems

Proxmox VM auto start VM after found in shutdown state

by

4

I was having this strange issue, where a running busy VM stopeed all of a sudden due to high CPU or Memory overload issue. So manually had to start everythime. In order to avoid this, created a small script to start the VM in case if it’s down.

#!/bin/bash

# Set environment
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

su -

if [[ $(qm status 101) = *"status: stopped"* ]];
then
echo `qm start 101`

Force Stop Proxmox LXC

by

0

First try to unlock the pct (assuming your troubled container is 101):

pct unlock 101

if it works just stop and start again the vm. if it does’nt work (my case) try to stop with this

lxc-stop --name 101

if it’s does’nt work (my case) you can force stop with kill command

ps ax | grep lxc

then kill the process with your id (101 for me) kill pid (replace pid by the process name). After that you can just launch again you’r vm

Fix Proxmox (PVE) “can’t lock file ‘/var/lock/qemu-server/lock-xxx.conf’ – got timeout” (Proxmox can’t shutdown/stop virtual machine) (Proxmox kill/force stop virtual machine)

by

0

The Issue

When trying to “Stop” or “Shutdown” virtual machine from Proxmox (PVE) web gui, the “Cluster log” shows

end task UPID:pve:xxxxxxxx:xxxxxxxx:xxxxxxx:qmstop:xxx:root@pam: can’t lock file ‘/var/lock/qemu-server/lock-xxx.conf’ -got timeout
end task UPID:pve:xxxxxxxx:xxxxxxxx:xxxxxxx:qmreboot:xxx:root@pam: VM quit/powerdown failed

The Fix

We can manually delete the lock from following path

/run/lock/qemu-server
# The file will be
/run/lock/qemu-server/lock-100.conf
/run/lock/qemu-server/lock-102.conf
...

Make sure only delete the correct one!

You can also do it using script from this site-
