Back in 2013 the Jailhouse Hypervisor was announced as a partitioning hypervisor that's lighter-weight than KVM. Last year saw the release of Jailhouse 0.1 and finally coming out today is the next update: Jailhouse 0.5.

In the many months since the previous Jailhouse release, this Linux-based partitioning hypervisor now supports AMD64 (x86_64), ARMv7 architecture support, inter-cell communication foundations, improved isolation on x86, and support for larger x86 machines. The initially supported ARMv7 hardware for this hypervisor is the Banana Pi, NVIDIA Jetson TK1, and Versatile Express.

Those wishing to find out more about Jailhouse 0.5 can read today's release announcement on the Linux kernel mailing list.
