Shutdown when complete, change OS to RedHat 5 (32 bit), boot up
Build a fresh 9.1.2 VM using the same OVA in step 3 with the bootable 9.1.2 that you obtained from TAC Licensing.
DRS from the upgraded 9.1.2 to the fresh 9.1.2

Steps 10 & 11 is due to the incompatible version being VM’d in step 5, it causes “partition mis-alignment” and puts it outside of Cisco support if you leave it that way.
Isolating your VMs…
This is messy because you essentially have 3 versions of Call Manager running. 1 on hardware, 1 VM that matches your hardware version that gets upgraded to 9.1.2, and 1 that is the fresh install of 9.1.2. All VMs MUST be able to contact NTP during the install phase!
Here is what I did:
I installed my 6.1.4 VM onto a valid subnet that was fully routable. You’re correct in assuming this did NOT match the IPs of the hardware instance. This allowed me to get past the NTP and Gateway issues during the install.
Then I DRS restored 6.1.4 into my VM, and did the jump upgrade as found in steps 8 & 9.
Then I did a DRS backup of the jumped 9.1.2 VM and shut it down.
Then I built a fresh 9.1.2 VM using the correct IPs and restored the DRS backup.
I know that 6.1.x will give you the option of not using NTP. IF YOU DO THIS, THE INSTALL WILL FAIL RIGHT AT THE VERY END OF THE JUMP UPGRADE WITH A SCRIPT ERROR, APPROX 2-3 HOURS INTO THE UPGRADE DUE TO BUG CSCui85967
