Can't migrate VM with local resources: hostpci1

[WonderArn]

I've got two identical hardware nodes running in a cluster right now. I'm adding a third node this weekend and planning on setting up HA.

I've got a Windows 11 VM on one node. i've got GPU passthrough running and working well. However, I don't seem to be able to migrate that VM to another node. I get the error: Can't migrate VM with local resources: hostpci1

Is it possible to migrate VMs in this scenario or because of that local resource do you have to manually remove the hostpci1, migrate and add it back on the new node?

Any suggestions would be appreciated.

If the other nodes have the same device (possibly at a different PCI ID), then use Mapped Device (instead of Raw Device): https://pve.proxmox.com/pve-docs/pve-admin-guide.html#resource_mapping . Note that you first need to setup the Resource Mappings in the Datacenter web GUI.

EDIT: This was added in PVE 8: https://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_8.0 "Create, manage and assign resource mappings for PCI and USB devices"

That'll work. Thank you!
