      Does the VM I want to work from need to be offline?

        When attaching the disk? yes.

            Just creating a VM to test with and will update shortly.

                At least in 99% of all cases 😉

                But yes, what Scott told you should work out of the box. You just need another VM or something else that can read the filesystem. Depending on the disk image format, you could also use a loop-mount for example.

                  Would be useful to have xs drivers installed to the test system..

                    Probably a good idea.

                      Yep, that should work and I don't have to fuss with trying to pass USB through the host to a VM.

                        It's really just like pulling the hard drive out of one desktop and plugging it into another.

                          why? You can add new disks to VMWare while a VM is running without any issues. I'm pretty sure you can attach a pre-existing partition as well.

                            You can do the same in XenServer. At least with Windows as the guest. I haven't tried it with Linux.

                              You can't however do this if the source drive is running on a separate VM. (That VM must be powered off).

                              Which is what I did in order to do this.

                                Linux can do that, just needs a SCSI Scan run.

                                    VMware can do it reliably on its side, but it would still hose the data inside the drive.

                                      Sure, as scott said before, I totally understand why you don't mount a VHD to two running VMs - boom!

                                          Does the VM I want to work from need to be offline?

                                          When attaching the disk? yes.

                                          why? You can add new disks to VMWare while a VM is running without any issues. I'm pretty sure you can attach a pre-existing partition as well.

                                          You can do the same in XenServer. At least with Windows as the guest. I haven't tried it with Linux.

                                          You can't however do this if the source drive is running on a separate VM. (That VM must be powered off).

                                          Which is what I did in order to do this.

                                          Right, unless you unmount the source drive first. I don't even think VMWare can reliably do this.

                                          VMware can do it reliably on its side, but it would still hose the data inside the drive.

                                          If you unmounted it first? Or was this a system drive?

                                            Just cluster aware filesystem. GFS2, OCFS, VxFS would all work fine.
