How to configure and install kernel zone on Solaris 11.2
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 […]
How to install solaris 10 branded zone on solaris 11?
Oracle Solaris 10 allows you to create a Solaris 9 and Solaris 8 as branded zone on SPARC environment and not supported on x86.But oracle soalris 11 allows you to create Solaris 10 as a branded zone on both SPARC and X86 environments.For your information Solaris 9 and Solaris 8 branded zones are not supported […]

Solaris Zone(Containers) – Interview Questions
Here I would like to share interview questions regarding Solaris zones which will be normally asked for L2 level candidates in Solaris interviews. Now a days virtualization plays very important role in infrastructure market to reduce the data center space,power and utilizing hardware potentially. The virtualization goal is that utilizing the hardware without scarifying the application performance and reducing the operational cost. We will see some of the interview questions and its […]
