Proxmox Notes

Disable/Enable virtual machine automatic startup

qm set <VMID> --onboot  [ 0 | 1 ]

Shutdown virtual machine

qm shutdown <VMID>
qm shutdown --forceStop <VMID>

Reboot virtual machine

qm reboot <VMID>

List all virtual machine IDs

qm list | awk '$1 ~ /^[0-9]+$/ { print $1 }'

List virtual machine templates (slow)

for i in $(qm list | awk '$1 ~ /^[0-9]+$/ { print $1 }');
do
   vmconfig=$(qm config $i);
   vmname=$(echo "$vmconfig" | awk -F: '$1 == "name" { print $2}');
   (echo "$vmconfig" | grep 'template: 1' &> /dev/null) && echo $i $vmname;
done

List virtual machine templates (very fast)

for i in $(find -L /etc/pve/nodes/*/qemu-server/ -iname '*.conf');
do
   vmconfig=$(cat $i);
   vmid=$(basename $i | sed 's@\.conf@@');
   vmname=$(echo "$vmconfig" | awk -F: '$1 == "name" { print $2}');
   (echo "$vmconfig" | grep 'template: 1' &> /dev/null) && echo $vmid $vmname;
   rm -f /tmp/${vmid}.conf
done

Create linked-clone VM from existing template VM

qm clone <TEMPLATE VMID> <VMID> --full 0 --name <VM NAME>
