11 Aug 2014 How to configure and install kernel zone on Solaris 11.2 [37795]
By Lingeswaran Rangasamy

"In Oracle Solaris 11.2,we have new type of zone called kernel zone. This zone is almost similar to SPARC VM (LDOM) guests which can run on its own patch level and completely isolated from global zone. These kernel branded zones are support on both SPARC & X86 hardwares. But processors should support virtulization technology(VT) .In X86 hardwares, you have to enable this option in system BIOS,if your hardware is upported for VT. Let's see how we can configure and install kernel zones on Solaris 11.2..."

26 May 2014 Security Access Control With Solaris Virtualization [36634]
By Thierry Manfe

Numerous Solaris customers consolidate multiple applications or servers on a single platform. The resulting configuration consists of many environments hosted on a single infrastructure and security constraints sometimes exist between these environments. Recently, a customer consolidated many virtual machines belonging to both their Intranet and Extranet on a pair of SPARC Solaris servers interconnected through Infiniband. Virtual Machines were mapped to Solaris Zones and one security constraint was to prevent SSH connections between the Intranet and the Extranet. This case study gives us the opportunity to understand how the Oracle Solaris Network Virtualization Technology - a.k.a. Project Crossbow - can be used to control outbound traffic from Solaris Zones.

23 May 2014 Overview of Solaris Zones Security Models [36519]
By Darren Moffat

Darren writes, "Over the years of explaining the security model of Solaris Zones and LDOMs to customers "security people" I've encountered two basic "schools of thought". The first is "shared kernel bad" the second is "shared kernel good".

Which camp is right ? Well both are, because there are advantages to both models.

If you have a shared kernel there the policy engine has more information about what is going on and can make more informed access and data flow decisions, however if an exploit should happen at the kernel level it has the potential to impact multiple (or all) guests.

If you have separate kernels then a kernel level exploit should only impact that single guest, except if it then results in a VM breakout..."

19 May 2014 How to Set Up a Hadoop 2.2 Cluster From the Unified Archive [36518]
By Orgad Kimchi

Orgad writes, "Learn how to combine an Apache Hadoop 2.2 (YARN) cluster using Oracle Solaris Zones, the ZFS file system, and the new Unified Archive capabilities of Oracle Solaris 11.2 to set up a Hadoop cluster on a single system.

Also see how to configure manual or automatic failover, and how to use the Unified Archive to create a 'cloud in a box' and deploy bare-metal system..."
