Hi
I have configured KVM with Fedora Core 13 by enabling the KVM virtualization
option while installing OS.
I have successfully created the guest OS by using the virt-install API

/usr/sbin/virt-install --name centos5 --ram 512 --disk
path=/var/lib/libvirt/images/
centos.img,size=5 --network network:default --accelerate --vnc -c
/tmp/CentOS-5.3-i386-bin-DVD.iso

Os installed successfully and after rebooting am able to login to the guest
OS using the virt-viewer command using vnc viewer ..It shows

Booting from Hard Disk...
GRUB Loading stage2.....

But the guest os is not booted

I want to the create the guest os from existing configured disk
/var/lib/libvirt/images/centos.img.. What modifications should be done with
my configuration file ??
Pleas help me to solve this.

[root@kvmcluster ~]# virsh dumpxml centos5
