Hello. After upgrading to FC38 I have the following problem: After some time of inactivity (working in other windows in my FC38 KDE machine), returning to the virt-manager (4.1.0) and guest window does not happen. I see the window capture displaying "Virtual Machine Manager" or the name of my VM, but nothing happens. I still can switch back to the host machine. If I run "systemctl restart libvirtd", close all windows and run virt-manager again, after providing the root password everything returns to its normal state - the guest continues to run (from the same place), manager is working normally. Till the next "time-out" which is rather "long" - about 10-15 minutes. Does someone know what to do in such a case? Thanks Leon
