When building out a rocking cloud over this past weekend, the topic of networking specific to NFS on vSphere came up. One of the questions that was asked was if the “Management traffic” checkbox on a vmkernel needed to be ticked in order of that specifc vmkernel to communicate to the NFS export. I didn’t believe this to be the case, and after some quick testing, we confirmed its as not needed.

The next question that came up is an important one to consider in your implementations of NFS on vSphere– and it was the question of “which vmkernel will be used to communicate to the NFS export?”. It’s important to keep in mind that once the connection to an NFS mount is made, it will continue over the same vmkernel AND NIC that was used to establish the connection, so if you get it wrong the first time, it’ll stay that way until you break the connection and re-establish it (which in our case, we tested by unmounting the export, making our changes, and then remounting).

What I had learned a ways back that I believed to still be true was that the the IP of the NFS server would determine which vmkernel would be used by using the vmkernel’s route table, and if no specific route (or same subnet vmkernel interface), the default route/gateway would be used.

SRM5 with vSphere 5

One of the newly revamped technologies to come out of the vSphere 5 suite announced this week at VMworld is Site Recovery Manager 5 (SRM5)

This is an anxiously awaited upgrade after the success from SRM with vSphere 4.

I’ll cut right to the chase though. The biggest new feature to me in the Automatic Fail-back. That’s right, automatic fail-back.

This coupled with the newly announced VXLAN (VMware’s new extensible LAN networking) brings home the idea that gone are the days of having to re-ip everything in case of a disaster.

In addition to all this VMware announced that with vSphere 5, vSphere Replication. Which allows you to replicate your VMs with just the SRM licensing.

Exciting things coming out of VMworld!

I see “one-to-one” configurations used for Management and vMotion networks way too often, where a vMotion network will use one physical uplink, and Management will use the other, that’s it–

It’s a common configuration, and exists in environments of all sizes. Unfortunately, it represents a single point of a failure, and the potential for a really bad day if the Management network drops and your HA configuration starts shutting down your virtual machines.

And it’s so easy to fix!! Check out the video below to see the “problem scenario” and how easy the solution is to implement.


Does your company have business issues or questions around operations management in your virtual and cloud environments?

vCenter Operations is a clear a quick way to identify VMware performance problems.  You can maximize ROI by increasing VM density and also reduce the VMware Administrators time spent isolating performance problem by up to 80%. 

VMware vCenter Operations is designed specifically to simplify and automate operations management in virtual and cloud environments. It’s tightly integrated with VMware vSphere and uses patented analytics to provide you with comprehensive and actionable intelligence across the stack. The focus of vCenter Operations is to provide the intelligence and visibility needed to proactively ensure service levels, optimum resource usage and configuration compliance in dynamic virtual and cloud environments.

I wanted to share some new thoughts and a new solution for a known issue when using PVS 5.6 and XenDesktop 5 deployed via vSphere 4.1.

By now we’ve all experienced the issue wherein any templates containing a network adapter configured to used a vNetwork Distributed Switch will cause the XenDesktop Wizard to crash when attempting to query available templates. The real kicker to this issue is that if any storage in the chosen DesktopController host configuration contains a template with a Distributed Switch then the behavior will appear. It does not matter if those templates are part of another vSphere installation, only that they are sharing the same storage.

If you are in vSphere and click on Performance, you may end up running across this error:

After researching the issue I found a couple VMware KB Articles on the subject, but no conclusive fix to the issue that resolved the issue. After digging in I found that troubleshooting futher proved better results. Here’s the fix:

1. In my case the DB resides on a Server 2008 R2 box, so ensure you have the SQL 2008 Native Client Driver in place for your ODBC connection

2. Review the stats.log in the following location: C:ProgramDataVMwareVirtualCenter & look for anything that might catch your eye (failures, etc)

3. Ensure the following services are set to an active domain account (not a local system account):

* VMware VirtualCenter Management Webservices

* VMware VirtualCenter Server

Start those services with the proper network account, then log back into Virtual Center. You should not see the “Performance” tab Overview page displaying correctly.
