After booting my system and logging into my account, if I don't launch Gnome Boxes and select and start a VM immediately, it will hang and not present a list of VMs. Also, if I exit a VM to return to the main Gnome Boxes window and allow the app to sit in that state for a prolonged period of time, and then I attempt to relaunch a VM, Gnome Boxes will hang. Basically, hang means that I see a twirling cursor. To recover, I must reboot, login immediately after seeing the login screen, open Gnome Boxes immediately, and start a VM immediately. Otherwise, if I wait too long -- some indeterminate amount of time -- I see the hang again. Reproducible: Always Steps to Reproduce: 1. Reboot your computer. 2. Login to the Gnome desktop. 3. Wait about 10 minutes. 4. Now, open Gnome Boxes to see whether it presents the list of VMs. It won't probably. Actual Results: Gnome Boxes hangs with a twirling cursor. Expected Results: Gnome Boxes should present my list of VMs and be able to start them successfully.

I think that this issue might have been fixed. I rebooted my computer about 23 hours ago, and after this long period of time, I was able to launch gnome-boxes, see my list of VMs, and start a VM successfully. No more twirling cursor -- at least not this time anyway.
