Hello everyone, I have a question about templates that I would like to ask. I hope everyone can give me an idea, thank you


Jun 28, 2023
Due to usage scenarios, I cloned many virtual machines using a template within the cluster. However, when I tried to delete the template, I found that too many virtual machines were being cloned, causing the template to be being referenced. It was difficult to find which virtual machines were using the template one by one. Is there any API or command that can identify virtual machines using this template within the cluster and delete them in bulk?
You can grep for the ID of the template in the config files below /etc/pve/nodes.
I can find and obtain the template ID. What I want to know is how to find which virtual machines are using the template based on the template ID
The template ID is part of the storage configuration if the VM is a linked clone.
If the VM is a full clone it is independent and there is no reference to the template.
All of them are linked clones, because a template has been linked and cloned by many machines, so I want to use the template to find out which virtual machines are currently linked and cloned this template
grep -r TEMPLATEID /etc/pve/nodes
Hello, thank you for your command. I can now obtain the list of virtual machines currently using this template, but because it is distributed on different physical machines, deleting it will cause an error. Is there a way to delete it uniformly on one machine?
