Open Source Unix Shell Emulators for Mac

Lakka is a lightweight Linux distribution that transforms a small computer into a full-blown emulation console. Built on top of the famous RetroArch emulator, Lakka is able to emulate a large range of hardware and has some useful features such as Braid-like rewinding, joypad hotplug, and video streaming. Lakka is easy to set up and use. Once installed on your SD card, you just have to put your ROM on the card, plug your joypad, and enjoy your favorite old games. We also support PS3 and XBox360 controllers so you don't have to buy new ones. We try our best to keep the hardware required to run Lakka as cheap as possible. The software is optimized to run fast even on low-end computers. The power can be supplied by any micro USB adapter like the one for your smartphone.

Be warned this project was discontinued in 2013 and has not been updated in years.

OpenXCI is a Xen-based desktop hypervisor. Unlike other desktop hypervisors, it is not targeted at businesses wanting remote provisioning, but rather at individuals who want a high-performance alternative to dual/multi-booting.

EmuExec is the right answer to make emulation on linux as simple as possible. But it is more than a simple multisystem frontend, you just have to see it by yourself.
