Today’s blog post discusses how the OpenStack metadata service works, and it was written by Michael Crane, the OpenStack Lead in VMware’s Global Support Services(GSS).
OpenStack provides a metadata service for cloud instances. This metadata is useful for accessing instance-specific information from within the instance. The primary purpose of this capability is to apply customizations to the instance during boot time if cloud-init or cloudbase-init is configured on your Linux or Windows image, respectively. However, instance metadata can be accessed at any time after the instance boots by the user or by applications running on the instance. In this article, we will describe how the metadata service is implemented in VIO, how to access the metadata from instances, and how to leverage the metadata for in-guest customization.

Today’s blog post discusses how VMware NSX supports Neutron Subnet Pools. This article was written by Marcos Hernandez, one of the OpenStack specialists in VMware’s Networking & Security Business Unit (NSBU).
Neutron, the OpenStack networking project, continues to evolve to support use cases that are relevant for the Enterprise. Early on, OpenStack networking was focused on delivering overlapping IP support for tenant subnets. Over time, more complex topologies have been added to Neutron. In some cases, the network administrators may want to be in charge of the IP scheme used by the consumers of an OpenStack private cloud. These and other options, are discussed in a recent SuperUser article published by Wells Fargo, as well as in the Neutron-NSX integration documentation.
Cloud administrators need a simple way to update the OpenStack control plane as features are patched. The VMware Integrated OpenStack team included a simplified update utility in the platform to accomplish just that. Patches are applied using either the command line interface on the VIO management server or the VIO plugin in the VMware vSphere web client. Continue reading
Ease of management operations is key to a successful cloud deployment. VMware aims to simplify common OpenStack administration tasks such as compute and storage capacity expansion through innovations in our OpenStack management framework. Continue reading
