Cluster-wide template

[davit]

We have proxmox cluster with 3 nodes. We used to create VM template on each node and later creating new vms from those templates using
"qm clone <template_vmid> <new_vmid>"

In above case we need to keep managing 3 templates (as there are 3 nodes). So trying to see if there is way to have only 1 template which is visible for all 3 nodes and in each node we can use "qm clone" cmd to create new vm using same template ID.

The best way is to get yourself a NAS system where you can store the templates.

I still don't fully understand what exactly you want to achieve with this. Why don't you make a template, then clone the VM and simply move it and the storage to the corresponding node?

 

[davit]

cloning a new vm from template and then migrating to target node is taking too much time. I was trying to achieve faster solution i.e directly clone vm from template to target node (target can be any node in cluster not just node which have template)
So based on above comment we can say there are only 2 ways to do this?
1. attach NAS/NFS shared storage to nodes in cluster and keep templates there or
2. clone a new vm from template then migrate to target node

2. clone a new vm from template then migrate to target node

I think, this approach would be functionally equivalent to what you are doing now. Still moving data from one node to another, just at a different point.

The only way to speed things up is to have Shared Storage. It may be sufficient to have just shared Template storage. However, the template is still "owned" by a node, so you you can only clone to local storage on that node. You'd need two steps, migrate Template to target node, then clone it locally.

If you have Shared Storage for both Template and VM images, then you can make fast clones to any node.
