Yes, just to confirm the XenAPI driver will automatically resize disks
where it can without needing an agent / cloud-init installed in the VM.
It does this by mounting the disk in the domain running nova and
resizing the filesystem/device.

My understanding is that automatic resize will occur if the
following are all true:
* auto_disk_config=True is set as a property on the image in the
Image Registry.
* The disk on the image has only one partition.
* The file system on the one partition is ext3 or ext4.
I think Xen provides some extra help in this area by doing the resize
itself (I *think*). KVM defers the job to the user.
There was a long discussion on the openstack-operators list about
building CentOS images:

The td;dr version would be this post where I link to some scripts that
are able to build a complete CentOS image that resizes as you would
expect:

Hope that helps,
