Proxmox Unlocking VM

I aborted a backup task of one of my VMs. That resulted in Proxmox keeping the VM locked. When wanting to restart a backup, I couldn’t. How does one unlock a VM?

Turns out it’s rather easy.

  1. Click on the node (“pve” in my case, the default)
  2. Click on the shell button (top right)
  3. In the appearing terminal, enter qm unlock <vm number>

That’s it. After closing the terminal, Proxmox refreshed the state automatically and my VM was unlocked.
