virt-manager general resolution of guest systems

#1 Post by modo72 »

Hello out there, I want to change the general screen resolution of the guest I manage with virt-manager/kvm. I think there was a virt-shell command to do that. The reason is, that I often install guest systems without a X-server and I want to have a higher screen resolution without touching the grub config on these systems each time. Does anyone know how to do it?

THX

Best regards /Chris

Both the built in VMM viewer and the stand alone virt-viewer can scale the guest in the host window, so no need to change the guest resolution. ?

Sorry for the late answer.
  • I evoked the virt-shell (virsh) and edited the domain of my VM.
  • Within the domain document I changed the vgamem from 16384 tp 65536
  • I already changed the screen resolution in /etc/default/grub which are now effective, after this action
