VM is Linux with GUI, after few minutes inactivity I see 'guest disabled display' instead of login screen and I can only reboot vm. How to fix it? I didn't set QEMU Guest Agent on that vm.

first i'd update your host to a current version, then maybe it a energy saving feature of your guest? (like suspend or display timeout?) did you try for example installing and ssh server and connecting that way?
