My guest OS sometimes unexpectedly reboots.
After I back to my PC and recover from sleeping, the host OS sometimes shows as the OS just started: all having run applications are not started; or host OS shows only black screen except blinking underscore: any input is not accepted and it makes me shutdown the host forcibly...
It sometimes occurs very short time sleeping even though according to my PC's setting about the time for sleep system, only display sleeps, on the other hand sometimes though I fold my host laptop guest OS lives. The trouble occur not always and I don't know when it does.
Are there any helps about this?
My environment:
Host PC: HP Spectre x360 13inch(2018) & Windows 10 1809
Guest OS: Ubuntu 18.04 LTS
Regards,
