How to get Windows 10 VM to work with WQXGA resolution?
I am using SEA-BIOS.
This bios does not support WQXGA (2560x1080)
I found a modified vgabios-qxl.bin file on the internet. The file can be copied to / user / share / qemu / and you can get more resolutions. Unfortunately, restarting UNRAID overwrites the standard file

file vga

vgabios-qxl.bin

The change is not persistent because unraid loads in ram, all the system files are in the compressed bzroot file and extracted into ram at each boot.

Moreover, as far as I know it is not possible to load a custom rom (romfile) in libvirt for the <video></video> block.

The only solution I see is to automate the copy/replace of that file when the array starts with a user script.

Could you please send us a sample of such a script?
I am not very strong at writing scripts

Something like this should work, set it to run at array start:

#!/bin/bash

#DEFINE VARIABLES#

SourceFile='/ABSOLUTE/PATH/TO/YOUR/vgabios-qxl.bin'
TargetFolder='/user/share/qemu/'

#COPY VBIOS#

cp "$SourceFile" "$TargetFolder"

 

Copy your vgabios.qxl.bin somewhere accessibile to unraid

Modify the path of SourceFile

Check TargetFolder is correct
