OMV hangs at startup on VirtualBox after fresh install

Hi,

I installed OMV 5.6.13 on VirtualBox 5.2.8. (2 GB RAM). The installation succeeded very fast and without issues. However on reboot it hangs after checking the disk and the CPU usage stays at 100%.

I rebooted and changed "quiet" to "single" the Grub boot parameter so that I can see more details.

The startup hangs at activating swap (see attachment).

Why is this happening? Is there an issue with running OMV under VirtualBox?

I am not sure exactly what was wrong, but I managed to fix this by:

1. Upgrading to VirtualBox 6.1
2. Changing the Graphics Controller to VMSVGA (at the GUI's suggestion after the upgrade)

The VM started up very fast.
