Host OS rebooting every night

[ssintay]

I believe that some interaction with the host OS and the VMware is causing the host OS to reboot everynight, and as a result the VMware OS goes through a hard reboot.

I am running OSX 10.9.5 on a MacBook Air with VMware fusion 7.1.1. I am running Windows 7 enterprise.

I have verified that the power management settings in windows 7. They are to never turn off the display and never put the computer to sleep.

In OSX the system will sleep after 15 minutes on both the Power Adapter and the Battery.

I do not have a problem with VM or the host system after waking the host system up from sleep. However, at some point over night the host system will reboot with a hard reboot.

When I close VMware it does not reboot over night.

Any ideas?

Thanks

Letting the host sleep while a VM is running can cause all sorts of funky problems.  Best practice is to manually pause the guest in fusion first, then sleep the host.

Thank you. I reset the sleeping and shutdown timing to allow the VM to sleep first. I have been running like this for over a week, and I have not had the host reboot.

Cool - glad it worked!
