My maximum screen resolution in the (Alpine Linux) VM is stuck at 1024x768 ?

After having "googled" and finding myself chasing my own t(r)ail, have come
here for advice.

phase 1 :
- installed Alpine Linux v3.9 on Lenovo Carbon X1 (rev 5) and  X11, DWM,
KVM,...
- installed Alpine Linux v3.9 in a VM and X11, DWM, KVM,...
- installed Windows 10
=> everything worked fine (remote-viewer)

phase 2 :
- update/upgrade Alpine Linux v3.9 on host and guest
=> screen resolution on Alpine Linux VM limited to 1024x768, Windows 10 fine

experiments, experiments, experiments (several weeks of...)
- also upgraded everything to Alpine Linux 3.10, also tried edge, nothing
helps
- also tried installing another linux distro (in a VM), same problem

What stomps me is that Windows 10 VM is working fine (except for the one
time I installed the "latest and greatest" spice-guest-tools => also 1024 x
768)

Any help/pointers appreciated

What kind of virtualization are you using? Qemu? VMware?
Check the video driver you are passing into the Alpine instance.
For example, I use `qxl` often with qemu.

I'm using KVM with Spice and QXL.  And it did work fine until I upgraded
Alpine (no other packages installed or anything changed otherwise)

Found the solution

try : replace (in the qemu command to fire up the vm) -vga qxl by -device
qxl-vga,max_outputs=1
close your eyes, click your heels 3 times and whisper "I  want to go home"
