Eric, sorry about not addressing the list. I don't know what made me
think you had replied off-list.
Thanks for digging into this for me. I'll study the VB forum links you
found and return to the qq I've posted there. Hopefully I'll get some
love there.

Hi,
please keep the discussion on the mailing list (and don't address me

the solution.

Hi Eric,
When I tried to reproduce the original VM by clicking on the .vbox
file, I got this error message:
Failed to open virtual machines located in .../VirtualBox
VMs/Windows10 VM/Windows 10 VM.vbox. Callee RC: NX_ERROR_INVALID_ARG
(0X80070057)
You are probably better off asking in a VirtualBox forum. Reading
through https://forums.virtualbox.org/viewtopic.php?t=110774 I get the
impression that the issue is some expectations on the devices (there
the ISO) being available on the host, which are most probably not part
of the backup.
See especially the comment

Nearly as I can tell from searching, that's a kind of generic error
message that doesn't help much.
You are possibly right, I wouldn't know, I haven't used VirtualBox for
decades.
I think I should also be able to create a new VM by importing the old
.vdi image. But when I try that approach, VirtualBox can't find the
.vdi image, even though it's in the 'VirtualBox VMs' directory.
Somewhere in my vague memory, from years ago when I was more active
with this stuff, there's the idea that copying an image as image is
different from copying the files in an image. Could that be relevant
here? I definitely would have run rdiff-backup with the VM shut down.
Well, you can do backup from within the VM, at the OS level, or from
outside at the VM image level, but apparently here you've done it from
outside.
Sorry I can't help more but it sounds more like a VirtualBox than an
rdiff-backup issue.
KR, Eric
Thanks.

Hi,
I have no clue of virtual box but which error message do you get?
Did you backup the image while the VM was switched off? Else it
could get inconsistent...

I've been backing up my VirtualBox VM as part of my rdiff-backiup
of my Home directory (Fedora 40).
My Window 10 VM got destroyed, and I'm trying to recreate it, but
VirtualBox does not seem to be able to recognize or deal with my
restored rdiff-backup files of the VM. Everything seems to be
there, but VB doesn't seem to recognize the .vdi file at all and I
get an error when I click on the .vbox file, which is supposedly
what retriggers the new VM.
Does anyone know why I can't restore from my rdiff-backup of the
virtual machine? I thought I was being very prudent with backing up
the VM.
