Thanks for the suggestion about modifying the graphic drive, I'll give that a shot. In the meantime, downgrading to the QEMU package before the current one fixed the problem so it's something in the updated package. I've filed a bug report and will follow up there.In virt-managers viewer window, under details, there is a the performance view where you can see if the vm is alive. You could send keystrokes to the vm, like Ctrl-Alt-Delete, and check if the host can pause, resume, shutdown and generally communicate with the vm assuming you have the agent installed in W10. In this way determine if it is a host issue or if the guest has simply froze. If the guest interface has froze and the guest is still alive, the graphic driver could be the issue. I've seen some recent issues with QXL video, so maybe change the vm's video type - disregard performance differences and assess graphics stability. This may get you into a degraded, but stable desktop to at least check things within the guest.
If downgrading the host returned the guest to operation, then the recent logs within the guest should be attainable. The host journal may show errors, grep for qxl and vdagent which may show issue, if in use.
