QEMU

It took me forever to setup qemu. At least half a day. It was so cumbersome.

It is a free open-source emulator that Blackberry QNX uses to emulate a computer architecture’s processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems.

I use to test my target for open-source projects on QNX 8.0 and 7.1 with architecture x86_64.
