The kvm plugin allows you to convert your virtualbox drives to qcow2 (kvm format). You could create a tiny OMV VM and attach that drive to it. Then share it via nfs or samba.
A sharedfolder OR smb/nfs share OR something else?
shares/shared folders are just folders on a filesystem. You wouldn't actually delete the filesystem. If you want to remove a folder, just delete it.
Try the filebrowser plugin or use WinSCP to connect via ssh.
It's just a regular shared folder but you answered my question, thanks.
I didn't realize the KVM plugin could do that. That does sound useful. I have a bit to think about in how I'm going to approach things now.
Overall, I like the idea of converting my Windows install to a VM. I know I've seen some convoluted directions somewhere before on how to do that. As an alternative, I can install Windows from scratch, which would probably take a while longer.
My current thoughts are that I'll do this:
Copy the appdata share I made for docker containers in a VDI on the host OS SSD directly to the SSD. This step will take a while.
Reinstall Docker and the Plex, Jellyfin and Shoko containers in Manjaro using the config data that I copied in the previous step.
Prepare and copy Windows into a virtual disk. I'm a little fuzzy on the details involved.
Install and setup OMV on the old server. Install the KVM plugin and add the Windows VM.
Delete the OMV VM from the new server, clean up anything leftover and carry on from there.
That's about as far ahead as I've thought at the moment.
I read this guide but it doesn't really mention how to add an existing VM or set one up from an existing install. [How-To] Use the Openmediavault-KVM plugin
