Do i need to upgrade my hardware???
    
        

You need a host system with a HVM-capable CPU and HVM-aware BIOS.


If your hardware does not support HVM, you may use qemu or switch to pv 
mode (needs modification of the LiveCD ISO).

To use qemu just install it and run:

qemu -cdrom livecd.iso

Hi,
   I'm a newbie to Xen.

   I was using VMware until now to work on a guest OS which will 
boot  from a live CD. How to boot the same CD in Xen, and how to 
write a new  configuration file (vmx) file for this.
            
            
1. Create config file /etc/xen/knoppix (you can use any different name)


$ cat /etc/xen/knoppix


kernel = "hvmloader"
builder='hvm'
memory = 128
name = "knoppix"
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/path/to/your/knoppix.iso,hda:cdrom,r' ]
device_model = 'qemu-dm'
sdl=0
vnc=1
vncpasswd=''
stdvga=0
serial='pty'
boot='d'


2. Start the domain 


xm create knoppix


3. Attach to its vnc console:

vncviewer 127.0.0.1:0




Note that bridge xenbr0 must exist!
If your virtual bridge's name differs from xenbr0, specify correct 
name in the config file.




Also you can google for any information related to Xen HVM domains.

        
          
   I'm working on a Intel P4 2.8GHz based Desktop PC with 2GB of 
RAM. Do i need to change my configuration?

   Please give me steps.

Thanks in advance,
Sairam
