Jailhouse is a type-1 hypervisor developed by Siemens and released as Open-Source software.

To build ERIKA Enterprise for Jailhouse, you just need to set the JAILHOUSE_DIR environment variable equal to the directory containing the Jailhouse built objects. When running make the build process will create a binary file by linking the ERIKA object file to the Jailhouse inmate library.

In case of cross-compilation, you also need to put the cross-compiler in the PATH and set the JAILHOUSE_AARCH64_GCCPREFIX environment variable equal to the cross-compiler prefix.

The build process will create a .bin file. Once the jailhouse cell for ERIKA has been created (through the jailhouse cell create command), this file can be loaded (through jailhouse cell load <cell_name> <binary_file>) and started (through the jailhouse cell start <binary_file>).
You can refer to [1] for the documentation about running Jailhouse on the Nvidia Jetson TX1 board (already supported by ERIKA Enterprise).
