I have two VMs that run a DB2 database under a Linux guest OS. Only one database will be active at a time, though I'd like both VMs to be running at the same time.
The database would be stored on a virtual disk image (thinking .img, but open to other formats) backed by a SAN and that disk image would be attached to both VMs
Is it safe to have the virtual disk file configured in each VM if the virtual disk is only mounted by the "active" machine?
