I've been running a Win 7 Ultimate VM on a 2012 MacBook Pro (8 GB RAM, 256 GB flash "drive" for a few generations of the Mac OS. The VM is encrypted by Credant (a requirement of my Electronic Health Records vendor), but that's not caused any troubles with Mac OS updates (Mountain Lion to Mavericks). I'm still at Fusion 5.0.3, simply because it continued to work normally even with the update to Mavericks.
HOWEVER, my VM had grown gradually to use more than half the disk space on the Mac's internal flash memory boot volume, and when current gen MacBook Pros began appearing on Apple's refurb online store, I jumped for a 2.3 GHz Haswell Core i7, 16 GB RAM, 512 GB Flash memory boot "disk", TB2.
I just finished transferring everything from the old Mac to the new one (18 short minutes using Migration Assistant via a Thunderbolt cable!). Everything works fine except my Win 7 VM. The first time I launched Fusion 5.0.3 on the new machine and tried to boot the VM (yes, I had shut it down appropriately on the old machine before transferring it), Fusion asked for my Mac admin user password, then asked me if I'd moved or copied the VM. I answered "moved".
The "Starting Windows" animation of colored dots into the pulsating Windows logo proceeded normally, but hung there and then crashed to a blue alert screen after two minutes, reporting "BAD_SYSTEM_CONFIG_INFO", did a "crash dump", then presented me with a 2-choice window suggesting I try booting into Windows Error Recovery (doesn't work; repaints exactly the same screen instantly) or "Start Windows Normally" (repeats the aborted boot process).
I didn't think the VM should be affected by anything that I've changed, unless it can recognize the different processor and graphics coprocessor.
Any suggestions? Does anyone think a (belated) upgrade to Fusion 6 might help? I can't just reinstall my VM on my laptop when bound to Active Directory on my LAN at work because our EHR server will recognize that it's not encrypted and refuse to allow it on the VPN tunnel to the server. My IT support person is 50 miles away. I would guess he could support me remotely but I doubt he could recreate my VM's "whole disk encryption" remotely.
Thanks so much,
