Here are some quick tips on creating an OpenStack Glance image based on CentOS.  There is a collection of good in-depth how-to’s on the internet, therefore will not be duplicating it here.

Create a raw image to install OS into:

# kvm-img create -f raw vvl-centos6_4.img 15G

Install the OS (note, this is recommended to be done inside a GNOME desktop where KVM is installed:

# kvm -m 2048 -cdrom <centos ISO> -drive file=vvl-centos6_4.img.img,if=virtio  -net nic,model=virtio -net user

Then choose to install the Operating System. Once it is installed, add it to glance image manager:
