Subnet Pools with VMware NSX

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.

VMware Integrated OpenStack Video Series: Software Update

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

CVE-2015-7547

VMware Integrated OpenStack administrators should be aware of a vulnerability in glibc that needs to be addressed in the Linux VMs that run the OpenStack control plane.

The details of the vulnerability and the associated resolution can be found at the following locations:

VMware Integrated OpenStack version 2.0.x – https://kb.vmware.com/selfservice/search.do?cmd=displayKC&docType=kc&docTypeID=DT_KB_1_1&externalId=2144193

VMware Integrated OpenStack version 1.0.x – https://kb.vmware.com/selfservice/search.do?cmd=displayKC&docType=kc&docTypeID=DT_KB_1_1&externalId=2144192

If you have any concerns about the correct steps to implement the resolution, please contact contact VMware Support.

VMware Integrated OpenStack Video Series: Cost Analysis with vRealize Business

Cloud computing allows IT administrators to give their users near-unbridled access to IT resources. However, to maintain control over growth and capacity utilization, it is important to make users aware of the costs of the resources that they consume. This can be a challenge for OpenStack cloud operators since available solutions may require customization to correctly interpret OpenStack data points. Continue reading

Windows Images in Your OpenStack Cloud

Linux is not the only operating system in cloud computing; your OpenStack users may want to utilize Windows images too! Today, we discuss how to create your Windows VM for OpenStack and how to import that VM with the Glance service. Continue reading

OpenStack CLI Utilities On Your Windows Desktop

It seems like the majority of OpenStack users tend to work with a Linux or Mac desktop. What about the Windows users? Fortunately, the OpenStack CLI utilities we know and love (like python-novaclient, python-glanceclient, etc.) run just as well on Windows as they do on Mac and Linux. Although, there are a few differences in setting your environment variables as well as in how you format your commands. Continue reading

VMware Integrated OpenStack Video Series: OpenStack Log Analysis with vRealize Log Insight

OpenStack is a great Infrastructure-as-a-Service (IaaS) platform, but what happens when components in the control plane don’t act the way we expect them to? Well, OpenStack is capable of generating a significant amount of syslog messages to assist you with troubleshooting. How do we make sense of them all? Consider VMware vRealize Log Insight!

The vRealize team partnered with the experts in-house who operate our OpenStack development cloud to classify log messages according to each control plane component. The end product of that work is a free Content Pack for Log Insight that automatically adds OpenStack intelligence to the solution.

My colleague, Yogita Patil, shared a great blog post about the content pack. So, I won’t go into as much detail as she did. Instead, I’ll share the following video that provides a walkthrough of using VMware vRealize Log Insight for OpenStack control plane analysis.

 

Stay tuned for the next installment covering cloud cost analysis with VMware vRealize Business! In the meantime, you can learn more on the VMware Product Walkthrough site and on the VMware Integrated OpenStack product page.

Deploy OpenStack CLI Utilities for Managing Your Cloud

One question that has come up on the VMware Communities is, “How do I configure my desktop with the OpenStack CLI packages?”

Deploy The CLI Binaries

The community documentation has pretty good instructions on getting the various packages installed on Linux, Mac OS X, and even Windows. At a minimum, I recommend installing the following packages using pip:

  • python-novaclient
  • python-neutronclient
  • python-cinderclient
  • python-glanceclient
  • python-heatclient

example:

sudo pip install python-novaclient

If you would like an automated method for deploying the CLI utilities, check out my openstack-client GitHub repo, which leverages Vagrant. I selected Ubuntu 15.04 as my operating system since it comes with Python version 2.7.9.  Ubuntu 14.04 and earlier versions come with older Python versions which generate an annoying, but superficial, InsecurePlatformWarning message when you use the CLI.

Start Consuming OpenStack

Once you have configured your selected platform with the OpenStack CLI tools, it’s time to connect to VMware Integrated OpenStack!

If you have a verified SSL certificate in your installation, you can move forward with the openrc file that you can download from the Horizon Dashboard (see Figure 1).

If your VIO installation still has a self-signed certificate, you will need to work with the VIO administrator to get a copy of the vio.pem file stored on the load balancer VMs (/etc/ssl/vio.pem). Then, add the following line to your openrc file:

export OS_CACERT=/your/path/vio.pem

Be sure to specify the correct path in your file.

Next, load the openrc file contents as environment variables using the source command (Windows users will need to create environment variables that correspond to the openrc file contents using the standard System Properties dialog). You will be prompted for your password. Then, you will be able to run commands like nova list, cinder list, etc.

Let us know if you have any questions about getting the OpenStack CLI utilities working on your desktop!
