I've only done text-based installations of CentOS under KVM, so I 
can't comment on VNC options. Here's an edited form of a standard 
virt-install script:

virt-install \
   --name="VMName" --ram="1024" --vcpus="1" \
   --nographics --accelerate \
   --os-type="linux" --os-variant="rhel5.4" \
   --network="bridge:br0" --mac="54:52:00:12:34:56" \
   --disk="path=/var/lib/libvirt/images/VMName.dsk,size=20" \
   --location="http://some-mirror/centos/5/os/x86_64" \

As always, double-check to make sure that, e.g., the network option is 
configured appropriately for your environment.

If you're doing a kickstart installation, the "ks=..." stuff goes 
within the extra-args option.
