Hi,

I have a CentOS 7 VM. Since changing the network setup from Nat to a Nat Network I start getting the GURU errors.
This occurs when I close my VM by either "Power off the machine" or "Save the machine state" and then try to start it. Sometimes it boots ok sometimes not.

I'd much appreciate your help. For more info, I've attached the pertaining logs.

Kind regards,
Andrusa

00:00:00.593528 Console: Machine state changed to 'Restoring'

I'd like to ask you to repeat the log gather after a clean start, not a restore. Discard the saved-state and start from a cold boot, after you've made the changes below.

Shut down the VM. Go to the VM Settings » Display » Screen. Change the Graphics controller from "VMSVGA" to "VBoxVGA". Increase the VRAM to the max 128 MB.
