vSphere Upgrade – Moving to dvNetworking Take 2? Update 2….

Since I adopted vSphere, I have been meaning to move to distribute virtual networking, but other things got in the way, such as my upgrade to a blade infrastructure as well as just general maintenance.Well I finally gave it a try. I have 4 basic networks, each for their own trust zone. 3 of these 4 migrated quickly and easily, but the last one was proving a bit difficult as it contained the service console of the vSphere ESX hosts as well as the administrative tools to manage the vSphere environment.

Cisco Pushing More vNetwork into Hardware

In the first Virtualization Security Podcast of 2011, we had Brad Hedlund with us once again. Not to talk about the Cisco Virtualization Security Gateway (VSG), but about the security of what I call physical-virtual devices that provide network virtualization within the hardware. Or what Brad Called Network ID Virtualization (NIV). Cisco has taken its VN-Link technology to extend the networking of a VM directly into the core switch when using vSphere.

vNetwork Security: Looking at VLANs

There is nothing like fully understanding the protections inherent within your vNetwork and the Roles and Permissions you can set within the virtualization management tool suites to ensure your vNetwork is secured, audited, and monitored for issues. Just like you do now within the pNetwork. Unlike the pNetwork, the vNetwork provides a certain amount of introspection and capability that is missing from a pNetwork, and this will also help with security.

Rethinking vNetwork Security

Brad Hedlund of Cisco asked the question, should the physical network security policy be different than the virtual network security policy? The answer is obviously no, but why are they treated separately? I and other have pushed the concept that to gain performance, redundancy, and security that you should use multiple network links to your virtualization host to separate traffic. However, does this really give you security?

vSphere Upgrade Saga: vCenter 6.5 Fails – vDS/DRS Issues

The latest vSphere Upgrade Saga happened a week or so after my upgrade to vSphere 6.5. VMware vCenter just up and died on me. I looked at everything and eventually had to call in VMware Support. That is a rare action for me these days, but it is nearly impossible to debug vCenter without their …

VMware NSX Conversations

At VMworld 2013 and on the Virtualization Security Podcast there were many conversations about VMware NSX. These conversations ranged from how will we implement this new technology to security, scale, and other technical questions. In addition, NSX and what was needed to make it a reality may be the answer to a nagging security question. Brad Hedlund, from the VMware NSX team, joined the Virtualization Security Podcast to share with us some of the details around VMware NSX prior to the podcast.
