List of Useful Proxmox Command

It's been some time since i wrote something in this blog. I've been pretty busy with product building till i lose track of time. Time sure pass quickly. Recently i've a chance to work on Proxmox again. It is still as powerful as ever and many more version came up and so are the problems. Hence, i figured to list down those command that i come across that might be useful one day. I'll bring it into a few sections for easy navigation in the future.

  9. View sorted list of VMs like vmid proxmox_host type: cat /etc/pve/.vmlist | grep node | tr -d '":,'| awk '{print $1" "$4" "$6 }' | sort -n | column -t
  10. View sorted list of vmid: cat /etc/pve/.vmlist | grep node | cut -d '"' -f2 | sort -n
