windows 10 guest dwm crash on default paravirtualization interface

Post by emwaving »

After recent windows 10 host update, virtualbox 6.1.xx running windows 10 guest becomes very slow - the cause is dwm keep crashing, flashing with black screen forever. (Same problem on 6.1.30 or 6.1.38)

The only workaround i found is to use legacy paravirtualization interface.

CPU:Q9550 (very old)
RAM:16GB
Host: Win10
Guest: Win10

Lots of people have VMs which are successfully using the paravirtualization API to talk to VirtualBox, so I'm not satisfied by your suggestion.

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.
