I am running CentOS 7 and windows 10 guest. Trying to get 4K on Windows resolution. I did the "virsh edit Win10" and found the video setting an changed it to 64M. After shutting down and booting back up (all of virt-manager) my resolution is still not higher the 2560x Anyone gotten 4K on windows guest ? Whats the trick. I am using QXL. Thanks, jerry
