[SOLVED] VM with multiple monitors

[proxale]

Has anybody tried or is it possible to run a VM that uses multiple monitors for extended desktop? i.e. able to drag an application window from one screen to another. In normal kvm/libvirt, it seems that this is possible by adding QXL devices. However, the ProxMox interface does not appear to allow adding more "displays" to a VM.

If you are connecting to Windows VM you can use this manual - https://www.itechtics.com/use-multiple-monitors-rdc/

I think the same could be achieved with Linux too.

Besides the suggested RDP option, you may give a try to SPICE [1].

Thanks, this looks interesting but seems to be Windows only. However, this gave me a direction to look into and found some other tools that work on Linux.
A few like RemotePC and Nomachine are commercial software but this free and OSS app https://remmina.org/ had been reported on reddit to work like multi-mon rdc.

I think this is the same approach I found previously, which requires multiple QXL devices to added to the VM but ProxMox by default doesn't support this functionality.

p.s. I am blind, missed the part in the doc where it teaches how to enable multiple QXL. The option is to switch the Display type
