Simplest way to destroy a VM from CLI in a cluster with HA ?

[YAGA]

Hello,

In a cluster with HA, a VM that was created on a node may have changed nodes.

What is the simplest way to destroy a VM by its VMID from CLI when you do not know on which node it was automatically migrated by HA?

I haven't found anything simple with just one command line

You won't be able to do that with one command. There is no central endpoint with Proxmox VE. You will first have to pull the list of all VMs to see which node it is running on.

Thank you @sb-jw for your answer, I will look into this but maybe someone has already done this with one or more simple CLI commands.

All you have to do is replace 9999 with your desired ID and you will have the node on which the VM is currently running.
pvesh get /cluster/resources --type=vm --output-format=json | jq -r '.[] | select(.vmid==9999).node'

Hi,

Sorry @sb-jw for not responding sooner and many thanks for your input.

Based on your suggestion I have written a one-line command to convert VMID number to host IP, but I don't like my code.

9999 is the VMID and the result is the host IP.

pvesh get /nodes/`pvesh get /cluster/resources --type=vm --noborder --noheader | grep "/9999" | awk -F ' ' '{print $14}'`/network --noborder --noheader | grep "vmbr0" | awk -F ' ' '{print $2}'

Does anyone have a better solution?

You could just use json:

pvesh get /nodes/`pvesh get /cluster/resources --type=vm --output-format json|jq -r '.[]|select(.vmid == 3002)|.node'`/network --output-format json|jq -r '.[]|select(.iface == "vmbr0")|.address'
172.16.100.201

But I dont understand why you need the node IP? Once you know the node "owner" of the VM, you can just send the PVESH to that node from any other node.

echo pvesh get /nodes/`pvesh get /cluster/resources --type=vm --output-format json|jq -r '.[]|select(.vmid == 3002)|.node'`/qemu/3002
pvesh get /nodes/pve7demo1/qemu/3002
