Open Stack

Hi Georgios,

1. I haven't seen that problem in my environment using pre-build cloud
images. But I haven't build an image from scratch myself except using the
magic "build-openstack-debian-image" command in debian.
   But this is certainly not the expected behavior. A well-built cloud
image should create the exact number of NICs according to nova/libvirt's
request.

2. Resizing the root filesystem is done using file system specific tools
like resize2fs and xfs_growfs. You can check the source code of cloud-init
at:
http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/cloudinit/config/cc_resizefs.py

Are you building the image for studying or for production use?



*YY Inc. is hiring openstack and python developers. Interested? Check
