Disk information are not being flushed from VBoxSVC's memory to the media registry

Reported by: Anderson M. Gomes Owned by:

Description

I have a set of VHD files from a virtual machine that was created in a Hyper-V installation. I am able to attach those files into a new virtual machine in VirtualBox, however I'm unable to use them again after closing the VirtualBox window or rebooting the host computer.

I believe the bug happens because VBoxSVC is not saving information about disks it knows to the media registry. I can reproduce the the bug by invoking a sequence of VBoxManage calls from a script: 

$ bash /tmp/vboxbug.sh 
+ vmname=VHDBUG
+ rootdir='/home/vboxbug/VirtualBox VMs/VHDBUG'
+ wait=true
+ killall -0 -v VBoxSVC

The problem is NOT reproducible on VirtualBox 6.0.0. It has been fixed now, however I am currently unable to close this ticket by myself.
