I'd like to build a CentOS 6.3 image with cloud-init. Is there a cloud-init RPM compatible with CentOS 6.3? If so, where can I find it?

How are you creating CentOS images? I am using Boxgrinder meta-appliance for creating CentOS images (qcow2 format). The VM images work fine with Openstack but as soon as I add the cloud-init package, I am unable to ssh to the VM although the VM is ping-able.

At CERN, we just use the cloud-init package from EPEL.If you search for cloud-init and EPEL, you'll find the details. It works well.

I managed to build a CentOS image with cloud-init package from EPEL, everything seems to be working except that when I have ephemeral space allocated, the root filesystem doesn't get resize to the correct allocated space. Have you seen this issue? Thanks for your help.

See, and in particular, the centos-image-resize script which must be installed in the image

Hi Lorin, yes I did follow that instruction and downloaded the script centos-image-resize script. It worked with vm-flavor that doesn't have ephemeral disk allocated but if I select the vm-flavor with ephemeral disk, it creates the correct 2nd partition but the root disk doesn't get resized.

@splca1 See for more details on how to use this script, I also recommend you ask a separate question on about this

I tried executing the instructions from, I can't seem to get my instances to resize. I see the disk size matches the flavor(/dev/vda), however the / partition will only show the qcow image size(2GB). Any special flags needed for glance import?
