SPICE memory higher than 32MB

Is there a way to increase spice memory to higher than 32MB via gui ? Or would it bring any performance benefit ?

Hello,

Is there a way to increase spice memory to higher than 32MB via gui ?

Yes, you can click on SPICE option in PVE UI -> VM > Hardware then set the size what you want.

Or would it bring any performance benefit ?

This can enable higher resolutions inside the VM, especially with SPICE/QXL.

When I go above 32MB I just get black screen on a guest.

How much MB did you set on the VM?

Can you post the config of your VM qm config <VMID> and the output of pveversion -v?

I turns out I wasn't patient enough, the black screen happens after each change of memory size and can take up to 5 minutes after which it just keeps working without delay on each reboot.
