What I've done so far is boot from Hackboot_mav.iso then replaced that with the Mavericks .iso, hit F5 and started the install. However the problem seems to be that the computer is stuck on "hfs: mounted OS X Base System on device root_device". It hasn't progressed for 25 min.
Virtualization set enabled in the BIOS
For the VM I gave it 2GB of RAM, 50GB storage, and disabled EFI.
