Combining power-safe filesystem images

I am working on 2 separate projects. They both are built to each produce a power-safe filesystem image. These images (*.img) are built with different BSPs. I want to run both images simultaneously, initially on the x86 QNX virtual machine target. The programs will talk to each other using inter-process comms.
I am still a relative newbie with QNX so I don't know how to do this. So far I have built one application that I can debug on the x86 QNX Virtual machine target using momentics. This didn't involve images - bootable or otherwise.
Do I just need to add the 2 applications to a build file, or do I need to use diskimage or something else?
I'd really appreciate any help!
Thanks.
