As far as I can tell it's the Hypervisor extension flags list. The lack
of these extensions/optimisations might explain why your FreeBSD VM runs
slow but their presence also causes the nVidia driver to refuse to run.
(Can't remember where I read this, sorry)
With your change to PCI_EMUL_MEMBASE64 I can boot a CentOS VM without
the "pci=nocrs" kernel option and nVidia card is assigned BARs without
However, even with reapplying the changes to vmm.ko to hide/remove the
0x40000000 CPUID support and CPUID2_HV, I still have the same
"RmInitAdapter failed" issue.
Allegedly nVidia VM checking came in with driver version 337.88, with
more checking after version 344.11. I couldn't install version 319 as it
failed to build the Linux kernel module. I currently have 370.28
installed which supports both my GT610 and my GTX960.
