This is the actual Xen hypervisor.

How is this generated ?
I mean if  I get the source code from the git. How should I generate
xen-3.0.gz ?

Xen hypervisor/tools source is only in mercurial repository at xenbits.xen.org.
pvops kernels are in Jeremy's xen.git repository.

Download, configure and compile. Some pre-built kernels are available in
many distros.

3.0 is a pretty old one, you should use 3.4.
You download the code, load some dependencies, compile and install.
For me (debian) the minimal dependencies are :
linssl-dev
zlib-dev
bin86
bcc 
elks-libc
python2.5-dev
python-xml
Many distros have pre-built Xen packages.

You will have to install a whole system in your Virtual Machines, most
kernels are working very well under the Xen hypervisor, you can even
create Windows virtual machines.

Assuming I have all the dependencies installed , how do I generate
xen-3.4.gz ??
is this the bzImage renamed to xen-3.4.gz ??

When you install (after compiling or by package) the Xen-x.x.gz is
installed in the right place (/boot partition), you will have to
configure your boot loader to load :
1) XEN
2) the lminux kernel
3) the "initrd"
Different versions of GRUB (or grub2) does have differences in the
"grub.cfg" file and the automatic generation gives bad results for Xen
installation (at least on Debian) and you will have to "hand craft" the
specific portion (On debian add a nice file in /etc/grub.d) or be ready
to redo the work after each automatic modification.
Many explanations on Internet, beware for GRUB's version as there are
some oddities.
