Have you had any luck getting this to work?
I'm having the same issue.
Despite a slight difference in the error message, this is the exact same failure as discussed in this other thread regarding ESXi on the new MacMini6,2 systems.
ESXi 5.0 will report NOT_REACHED bora/vmkernel/hardware/intel/vtd.c:4463
ESXi 5.1 will report NOT_REACHED bora/vmkernel/hardware/intel/vtd.c:3638
I've filed an internal bug report to investigate the issue.
No, I still face the same issue and this is a big pain for me.
Reason is under Fusion 5 I can install one ESXi v5.X but only limited to 8GB of RAM when I'm running in fact 16GB.
so I have to install a second ESXi 5 to run my demo :-(
In any case, it's a mess to not be able to install ESXi v5 on top of so beautifull and portable Hardware.
I've just found this article focusing on the new Mac Mini facing the same issue
I did not try it yet but it may fixed our issue on rMBP :-)
Here's a possible workaround...
Very early in the boot process, a prompt appears in the bottom-right corner of the screen to press Shift+O to edit boot options. At that time, press Shift+O and you'll get an editable line of text along the bottom of the screen with a cursor at the end. Add a single space followed by:
Then press the Enter key and the system will attempt boot.
