Please support to share a disk image between two guests

Description

Hi,

at the moment we face the problem that we need to test a cluster FS implementation within virtualbox, therefore we need to share a storage device between several guests. As current workaround we use a Linux guest providing an iscsi target. Things would be much more simple if virtualbox would allow to share one disk image between several guest systems.

Thanks in advance for implementing this feature,

Bernd

Rather dangerous feature for 99.999% of the users. Must be carefully hidden. Otherwise users will treat FAT32 as a cluster filesystem and get after us when they lose data.

Starting with 2.1.0, a disk image can be attached to two VMs at the same time, but only one of these two VMs can be powered on at the same time. Klaus already explained why we wouldn't implement sharing an image between running VMs. Closing.

I think it's a necessary feature for testing cluster configurations. The danger of enabling this feature may be explained in a comment or warning, but I think Virtual Box needs this feature to compete with VMWare.
