So to fix that I just clicked on the GPU PCI card that I added and clicked the option to "make reserved memory equal" for the OSX guest. Invalid memory setting: memory reservation () should be equal to memsize(xxxxx). I then had some errors when starting up the guest when I boosted the memory from 2GB to 16GB:Īn error occurred while parsing scheduler-specific configuration parameters.
To allow the OSX guest to more memory, you need to adjust some settings on the host: You then can add the GPU to the OSX guest using the "Add PCI device" option. Then you have to reboot your ESXi host for passthrough to take effect.
HOW TO LOAD OSX IN VM INSTALL
I found a Radeon HD6570 for about £40 and set up GPU passthrough in ESXi (I forgot to say that I did install Mountain Lion first without the Radeon card - I don't know if that would make any difference).įrom your host, select the configuration tab, then "Advanced Settings", then "Edit", and select the ATI card.
So I returned the nvidia and spent time researching AMD Radeon cards here: I originally bought a nvidia GT 640, as it looked to be quite compatible with Mountain Lion, but in the end I found out that ESXi passthrough with nvidia cards did not work too well: I spent a lot of time looking at these sites and searching with Google to find the most inexpensive and compatible out of box video card for Mountain Lion:
OK, here is an update of the progress that I've made so far with installing Mountain Lion on my ESXi 5.1 box with GPU passthrough for accelerated graphics.
