CentOS virt - Apr 2008 - full virtualisation on centos5.1 with a F7 guest

Hi

I m trying to install a full virtualized guest on my dell poweredge 1950 
with centos 5.1 64 bits.
I just launched the following command

virt-install -n elaphe -r 4096 -f /var/lib/xen/images/elaphe -s 40 -b 
vlanbr15 --hvm

Would you like to enable graphics support? (yes or no) yes
What is the virtual CD image, CD device or install location? 
/var/lib/xen/F-7-i386-DVD.iso
