The illumos project develops a Unix operating system core that was originally derived from OpenSolaris, providing next-generation features for downstream distributions, including advanced system debugging, next generation filesystem, networking, and virtualization options.
illumos is developed by both volunteers and companies building products based on the illumos system.
illumos is an excellent base for both traditional and cloud-native deployments.
We'll try to be around in the FOSDEM Matrix chat, but if you're like us and prefer IRC, please visit us on #illumos-fosdem on freenode. If you don't have an IRC client, try freenode's webchat.
Since last FOSDEM we had a couple of larger updates:
bhyve is a hypervisor running on Intel and AMD CPUs, providing fast networking and disk access to guest machines. On Intel systems it also supports PCI passthrough.
Zones are a lightweight virtualization mechanism allowing running another, completely isolated instance of the native OS on the same kernel. They were introduced back in 2005, designed from the ground up to be secure.
