Oracle Solaris introduced kernel zones feature in Oracle Solaris 11.2, which provides the flexibility, efficiency and isolation of Oracle Solaris Zones while adding the capability for each kernel zone to run in an independent kernel. Each kernel zone running on a host can be at a different kernel level and be updated individually. This allows application requiring different kernel version requirements to safely run side by side on the same system.
Veritas Cluster Server supports Oracle Solaris Kernel zones from VCS 6.2 onwards.
The article attached provides an overview of different scnearios in which Veritas Cluster Server provides availability to the applications running inside Kernel Zones and the Kernel Zone itself.
