You can check out existing examples and see how their device trees have been translated. It is an iterative process where you need to solve several issues until you have something working. Later could be hardening to remove bits that the root cell maybe should not be allowed to do anymore, once running under jailhouse. But the hypervisor will tell you about problems with reporting access violations, so the process could be called "guided". Maybe your research can be done on a board that is already supported. > - secondly, i'm not sure the linux distro i'll be using, which is the > openstlinux one, can work seamlessly with jailhouse > has anybody tried something similar?

That should not pose a problem for any distro. But again ... taking a problematic distro on a problematic board is not research, it is "BSP doing". For your research just take another board and i.e. jailhouse-images which will give you debian as distro. Or if your sponsor insists, you have to do the "BSP doing", which is not too bad but will cost. regards, Henning -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
