%description
This package contains the Xen hypervisor and Xen tools, needed to
run virtual machines on x86 systems, together with the kernel-xen*
packages.  Information on how to use Xen can be found at the Xen
project pages.

Virtualisation can be used to run multiple versions or multiple
Linux distributions on one system, or to test untrusted applications
in a sandboxed environment.  Note that the Xen technology is still
in development, and this RPM has received extremely little testing.
Don't be surprised if this RPM eats your data, drinks your coffee
or makes fun of you in front of your friends.

%description devel
This package contains the Xen development libraries and header files
for building addon tools.

%description kernel
The kernel package contains the Linux kernel (vmlinuz), the core of your
Red Hat Linux operating system.  The kernel handles the basic functions
of the operating system:  memory allocation, process allocation, device
input and output, etc.

This kernel has been patched to be a Xen Dom0.

Provides: kernel-source

%description kernel-sourcecode
The xen-kernel-sourcecode package contains the source code files for the Linux
kernel. The source files can be used to build a custom kernel that is
smaller by virtue of only including drivers for your particular hardware, if
you are so inclined (and you know what you're doing). The customisation
guide in the documentation describes in detail how to do this. This package
is neither needed nor usable for building external kernel modules for
linking such modules into the default operating system kernels.
