FreeBSD OS + Netapp … Switching VBox images between hosts ...

[Hub- FreeBSD]

Have two servers, share a file system through a NetApp … have vBox guest creating on ServerA, want to move it to ServerB … I'm not moving any physical files, the path will be  identical, etc … I just need "register" it on ServerB …

Is there an easy way to do this?   from what I've read, registervm doesn't *seem* to do it … d

Help?
