Package kernel-image-ovz-rhel: Information

This package contains the Linux kernel that is used to boot and run
your system.

Most hardware drivers for this kernel are built as modules.  Some of
these drivers are built separately from the kernel; they are available
in separate packages (kernel-modules-*-ovz-rhel).

The "ovz-rhel" variant of kernel packages is a RHEL5 based OpenVZ kernel.
OpenVZ is container-based virtualization for Linux that creates multiple
secure, isolated containers on a single physical server enabling better
server utilization and ensuring that applications do not conflict.
