Description of problem: Since moving to version 27 of Fedora virtual machines have slow response to mose and keyboard actions. I can not tell if it is screen update not happenig or if the action is not getting to the machine for a while. Machines used to be smooth to run but now are quite frustrating. How reproducible: upgrade host and clients to fedora 27, unfortunately upgrades were all done at the same time and so I can not place blame on host or client end. Steps to Reproduce: 1.Use Boxes or virtual machine manager to open the virtual machine console. 2.browse a web page or edit a document 3.note the delay when performing tasks like typing, moving mouse, selecting or using drop down boxes. Expected results: Same smooth operation as before. Additional info: 2 x Fedora 27 client machines running on well speced F27 host Using Virtio video Gnome Boxes and VMM console used with no difference in latency.
Did you enable 3D acceleration in the Virtio Video details? This greatly improved the speed for my VMs.
Please provide your VM config: virsh --connect qemu:///session dumpxml $VMNAME ~/.cache/libvirt/qemu/log/$VMNAME.log

So you have virtio video with GL passthrough disabled. Maybe in virt-manager try switching to video model=qxl and see if that makes any difference, it will help narrow it down at least
qxl makes it much more responsive, I do not need to move the mouse to see my typing any more. I have GL passthrough disabled as I use this as a VDI solution and GL is not network happy yet, not that I have network running at the moment due to the latency issue.
