Description of problem: fedora 25 kvm does not support 2560x1440 screen resolution on Windows 7 VM. Running latest updates of F25, KVM and QEMU but cannot set the screen resolution of 2560x1440 pixels (my screens native resolution) in a Windows 7 Home VM when the Display Adaptor is set to Qxl with 64MB. I checked the "List Extra Modes" as well but its not listed for the adaptor. The host os (F25) is running at 2560x1440 without any problems. HW is Asus P68, i7-2600k, 32GB RAM, 256 SSD and nvidia GTX950. Version-Release number of selected component (if applicable): Linux HOSTNAME 4.9.6-200.fc25.x86_64 #1 SMP DATE x86_64 x86_64 x86_64 GNU/Linux libvirt-daemon-kvm-2.2.0-2.fc25.x86_64 qemu-kvm-2.7.1-2.fc25.x86_64 qemu-common-2.7.1-2.fc25.x86_64 qemu-guest-agent-2.7.1-2.fc25.x86_64 qemu-img-2.7.1-2.fc25.x86_64 qemu-kvm-2.7.1-2.fc25.x86_64 qemu-system-x86-2.7.1-2.fc25.x86_64 spice-glib-0.33-2.fc25.x86_64 spice-gtk3-0.33-2.fc25.x86_64 spice-server-0.13.3-1.fc25.x86_64 spice-vdagent-0.16.0-3.fc24.x86_64 spice-xpi-2.8.90-10.fc24.x86_64 How reproducible: option to set 2560x1440 is not available so reproduciable everytime. 2560x1600 is available but that ruins the screen quality... Steps to Reproduce: 1. 2. 3. Actual results: have to run in 1920x1080 resolution. Expected results: would expect 2560x1440 resolution as host is capable of using it and does. Additional info:
Can you post your VM XML? sudo virsh dumpxml $vmname Are you using any virtio-win drivers inside the guest, or did you use spice-guest-tools.exe? (if you aren't sure, you probably aren't using them)
we took another long look at this problem and were able to fix it. SOLUTION: we installed the latest VirtIO drivers (0.1.130) which contained an QXL driver that supported the 2560x1440 pixel native screen resolution of my monitor. Issue can be closed.
