Hi Dave, I uploaded some screen captures that paint a better picture of what's going on. Please see the attachments to my above comments.
You suggested that I attempt to ssh into the frozen VM and, if possible, look at relevant logs. I was able to access my VM when its desktop was frozen, but honestly, I don't know what logs I should be looking for. I did, however, run "top" and noticed that one root process was at over 100% cpu usage while the desktop was frozen. Please see "top.png" attached to Comment #19. With regard to the QEMU logs on my host, I found nothing noteworthy. I'm just a hobbyist, and tracking down bugs is a bit beyond my skill level. With that in mind, I hope maybe you or someone else who is more capable than me would be willing to create an Ubuntu 15.04 VM and look a little further into this. Who knows, maybe this is just a quirk of my system. But if someone else can reproduce what I'm seeing, then this is probably a pretty big issue, even if not always noticeable.
