I have a mac virtual machine using vmware with a windows host. I need to install genymotion in my mac vm. The problem is genymotion uses virtualbox and when i try to run the genymotion vm, i get this error from vbox VT-x is not available (VERR_VMX_NO_VMX). This is a nested virtual so i want to know how i can get this to work if it is possible at all. Note: I tried intel hardware acceleration within the mac vm and got a similar error as well.

Is there any reason you cannot run the Genymotion VM alongside the Mac VM as opposed to within it? –  Mokubai Nov 17 '13 at 23:17
    
I want to develop and test my android app from a mac environment. I could use the android emulator but it is really slow. –  Jimi Nov 17 '13 at 23:38
    
I don't see why wanting to develop from within a Mac environment prevents you from running Gennymotion on the host. As far as your dev environment is concerned it will be connecting to a remote machine to do its work and having the machine appear "elsewhere" on the network (i.e. the host rather than the mac guest) should only be a matter of minor configuration work. –  Mokubai Nov 23 '13 at 16:31
    
What configuration change do i have to make? I already tried the "Vitualize intel vt-x or AMD-V/RVI" option in vmware and it didnt work. I also tried to edit the vmx file but i hasn't worked too. –  Jimi Nov 23 '13 at 21:58

No, it's not possible. Only physical machines can support VT-x. If VT-x support is required, the software must run on the physical machine.

Ok. But just out of curiosity, what does this option "Vitualize intel vt-x or AMD-V/RVI" under processor options do. While searching for an answer, someone said that enabling this feature will allow nested virtualization. It didnt work for me but i want to know exactly what it does. –  Jimi Nov 18 '13 at 8:57
    
That is what it is supposed to do, but it doesn't really work. –  David Schwartz Nov 18 '13 at 8:58
