You mean to use Dolphin on the virtual Mac? You wouldn´t see the true performance on it since:
1- Emulating any OS is hugely demanding (depending on how did you set your VM, of course).
2- The "emulated" OS will use the same components (CPU, GPU) your current machine is using; thus it would limit a lot the posibility to -e.g. get full speed on Dolphin- if your machine isn´t pretty powerful.
It´s not that is impossible to do, it just doesn´t give any benefit at all (in this case, give you a solid idea of how Dolphin would perform in Mavericks) I.M.O.
EDIT: But, if what your friend wants to do is to try Dolphin, the official benchmark would be a good start.
