Phoronix: Jailhouse v0.8 Linux Hypervisor Released

The past few years Siemens has been working on Jailhouse as a Linux-based partitioning hypervisor that has aimed to be a lighter alternative to KVM. It's been seven months since the last update, but now Jailhouse 0.8 is now available...

TLDR: the current state of this hypervisor is alpa. 2 ARM boards are well supported. X86 is well supported. Well supported means that you hand-configure memory and PCI reservations, hand-assign cores, hand-assign UARTs for TTY access, build host and guest kernels and intrd's, and don't use grub2 to boot guests. What you get in exchange is true bare-metal performance and true isolation of guests, but you also lose out on sharing underutilized resources between guests and host.

For those interested in learning about JailHouse, Here's a PDF describing bootstrapping and usage:

PS: if you come from pre-Plug'n'Play days this won't scare you. I was reminded of early days running DOSEMU on 1.x kernels and hand-configuring devices for real-mode access with DMA... lots of reboots lol.
