You should try "jailhouse cell linux" first, instead of the open-coded
approach (the latter was removed from docs in master). It automates the
steps a prevents some of the common mistakes along this.
The next question would then be where you got the kernel from
(queues/jailhouse from my tree?) and which config you are using.
