Create vm with 2cow format

[Servnet Mexico]

Good morning team, I hope you are very well, I am working to implement an application together with proxmox, however this application only works with qcow2 format, is there any way to create or convert a vm to qcow2? It does not matter if you have to start from a created vm or start a vm from 0.

regards!

When you choose a file level storage then you get a drop-down menu where you can select qcow2 both in the VM create wizard as well as when you add a disk to an existing VM in the GUI.

See the PVE Wiki page about storages.

I have tried to modify it in versions of proxmox 6.2 and 7.0 and this is not possible, it seems that it is blocked, I tried to add a new disk to an existing vm and create a vm but in neither of the two options it allows me, you will know how to unlock that option?

This is blocked on purpose in the GUI because LVM thin storages support only raw in Proxmox VE.

There is a wiki page about storages and on the bottom of it you can go to details for all available storage types. Some of them, for example Directory, will contain qcow2. So you need to set up one of those. Note that the default local storage is a Directory storage and already supports qcow2 as a result.
