Windows VM Some Hardware Greyed Out

[alfcasado]

Hello everyone,

I've ran onto this issue where I cannot seem to add any more USB devices to my VM, nor EFI Disks nor TPM states as the UI has them greyed out.
Has anyone run onto this issue and can provide some input on how to address it?

I'm on Proxmox 8.0.4



Thanks in advance!

The manual states:

usb[n]: [[host=]<HOSTUSBDEVICE|spice>] [,mapping=<mapping-id>] [,usb3=<1|0>]
Configure an USB device (n is 0 to 4, for machine version >= 7.1 and ostype l26 or windows > 7, n can be up to 14).

Looks like you are prevented by an old limit. Please share the VM configuration file (qm config.

nor EFI Disks nor TPM states as the UI has them greyed out.

There are 0 or 1 TPM and EFI disks possible depending on the VM type and you already have one of each. Therefore, no other is possible.

This solves the mistery for these two, but what about the USB devices? It should be fine up to 14 devices

Any idea why this is not working?

Maybe old code in the browser? Try clearing the cache and/or another browser. Maybe (part of) your Proxmox is not up to date? Please show the output of pveversion -v.
The work-around is to manually edit the VM configuration file in /etc/pve/qemu-server/ directory.
