I just added the VirtualBox plugin to my OMV 4.1.12 machine in order to run a small Debian x64 VM. It seems ok but I can't import or export anything.
Initially, I wanted to move a VM over from a VMWare server that I want to shut down, but VirtualBox wouldn't import the OVF, gave 'VirtualBox error: rc=0x80070057'. So I created a new VM and installed Debian 9.5 from scratch; that's up and running fine, but now I want to make a backup copy of it. I shut down the VM and tried to export it, but hit the same error 'VirtualBox error: rc=0x80070057'.
I've attached the full error output (it's too big for a forum post); I can't work out from it what's causing the problem, but perhaps someone can...
Has anyone run into problems with VBox on OMV 4?
