Virtualization in RHEL5

-
In Rhel 5 virtualization can be done in two ways

Para Virtualization
Full Virtualization

Para virtualization : Min 512 MB Ram and CPU must support PAE Flag

Full Virtualization :  Min 512 MB Ram and CPU which supports VMX (Intel Processors and vm AMD)

We must install xen Kernel, which supports virtualization to be supported in the server
and we should install virt-manager, Just like Vmware in windows

#yum install kernel-xen-2.6.*****
#yum install virt-manager


Whenever we install the xen kernel the following services will start

libvirtd
xend

Now to open virt manager in the server type the following command :

#virt-manager

click on New --> forward
-->VM1 (Guest os name)
 --> forward --> ftp://server1.example.com/pub (path that we have copied the RHEL5 DVD )
--> Normal Disk Partition (Seperate partition) ...and follow the on screen instructions


Note : to check the cpu info

#cat /proc/cpuinfo

The entire above process is para - virtualization

For Full Virtualization we need to install the package


I will provide the screen shots ASAP.
