I have the VMs in a separate ext3 partition, and the host systems in other partitions on the same internal hard disk. (So that they can repair each other) This should really give enough separation.

I dualboot Mandriva and Ubuntu, and have created several VMs under Ubuntu. Under Mandriva, all the virtual machines and hard disks are listed as inaccessible. I can fix this by unregistering and reregistering one virtual hard disk under Mandriva, and then create a new machine which uses this disk. I...

I tried to use the full path, and now my virtual machine files seem to be found and analyzed, but were found incorrect. Seems the VM files from VirtualBox 2.2 were useless for VirtualBox 3. The output was: ERROR: Could not load the settings file '/home/on/VirtualBox/gOS/gOS.xml'. Element '{http://ww...

(The ls command shows the path was right). As Virtual Media Manager sees these VMs, they cer...

And when I tried to register a VM from a command line, I ...

I tried to use my old VMs, a few months old, on my new computer, and Virtual Media Manager can see them all correctly, but VirtualBox evidently refuses to use transferred VMs. VMware has no problems with using transferred VMs, so it really seems I will be going with VMware, but I will give VirtualBo...

I just installed VB 2.2 under XP, but my virtual machines from August 2007, made by a then quite new VMware, don't appear in the leftmost column of VB. I first tried in Preferences to let Default Machines Folder point to the folder My Documents\My Virtual Machines, in which each virtual machine has ...
