Jailhouse: A Linux-based Partitioning Hypervisor

The official announce email ( <a href="https://lwn.net/Articles/574273/" rel="nofollow">https:&#x2F;&#x2F;lwn.net&#x2F;Articles&#x2F;574273&#x2F;</a> ) provides a bit more detail, including a link to the Jailhouse presentation at this year&#x27;s KVM Forum for the differences between KVM and Jailhouse: <a href="https://docs.google.com/file/d/0B6HTUUWSPdd-Zl93MVhlMnRJRjg" rel="nofollow">https:&#x2F;&#x2F;docs.google.com&#x2F;file&#x2F;d&#x2F;0B6HTUUWSPdd-Zl93MVhlMnRJRjg</a>

This is the most exciting kind of virtualization I&#x27;ve seen. I wish it was ready for prime time so I could use it for real!

This is interesting, in that it seems to be in compeiting space to LXC.. but makes use of VMX for machine isolation rather than using namespace &#x2F; cgroups.<p>It&#x27;s a shame they haven&#x27;t provided some benchmarks...

How do guests (ehm, inmates?) get access to shared hardware?

I&#x27;ve been working with FreeBSD Jails for quite a while now and this looks like a clone for Linux.<p>For those who don&#x27;t know, a FreeBSD Jail is a virtualization on the OS level (rather than Hardware level as provided by VirtualBox et al). It&#x27;s similar in concept to creating a chroot, but you&#x27;re also locking down processes.<p><a href="http://www.freebsd.org/doc/handbook/jails.html" rel="nofollow">http:&#x2F;&#x2F;www.freebsd.org&#x2F;doc&#x2F;handbook&#x2F;jails.html</a>
