Change existing VM From i440fx to Q35

[r00t9]

I have one Proxmox Cluster and i create VMs with Machine type i440fx. Can i change the Machine type for EXISTING VMs to Q35 or i need to create new VMs ?

If the guest is Linux you probably can just change it. If it is Windows you may need to repair afterward.

Why do you think you need to change them?

Of course you can change the Machine Type of an existing VM.

However you should note the following:

• The change will only be picked up after Shutting down & restarting the VM.
• Changing the machine type is similar to a MB change; so the VM may not run correctly after the change.
• Always have a backup of the VM - so you can always start again.

Not always (as you also imply). I just tested it on a trivial Debian Server VM - and although it booted correctly after changing to q35 from i440fx, it lost it's NW connectivity + GA. So anything is possible!

I’ll leave it for now. I was thinking of buying an internet card and a storage card.

I’ve done it in Windows, it redetects hardware including the network card as mentioned above.
