SUMMARY = "Linux-based partitioning hypervisor"
DESCRIPTION = "Jailhouse is a partitioning Hypervisor based on Linux. It is able to run bare-metal applications or (adapted) \
operating systems besides Linux. For this purpose, it configures CPU and device virtualization features of the hardware \
platform in a way that none of these domains, called 'cells' here, can interfere with each other in an unacceptable way."
