Free Veeam Monitor

In the event you haven’t heard elsewhere already, the special Christmas present that Veeam had in store for the virtualization community was a new, free version of Veeam Monitor. The addition of this free solution gives system administrators a new option for real-time monitoring of VMware Infrastructure environments.

That’s right, VMware has finally settled on a new name for would have been called VMware Infrastructure 4. The new name? VMware vSphere.

VMware ESX Networking Articles

Over the past few years—almost four years now that I’ve been writing here on this site—I’ve written quite a few articles on VMware ESX networking. Here’s a collection of links to some of the more notable, and hopefully more useful, articles in that group.

Using vmware-vim-cmd to Modify a Portgroup

While creating a command-line configuration guide for a design that I’d prepared, I found myself in need of a command that sets the NIC failover order explicitly for a portgroup. I suspected—and was correct—that vmware-vim-cmd would do the job, but was having a hard time finding documentation on the correct syntax. Even the extensive XtraVirt vimsh white paper did not have information on the syntax. After a little bit of digging around, I found the information for which I was looking. Here it is for future benefit.

Enabling Enhanced VMXNet

I’ve been doing some additional digging into jumbo frames and other networking configurations, and along the way I came across references to VMware’s Enhanced VMXNet network adapters. These were apparently introduced in VMware ESX 3.5 and are necessary in order for virtual machines to take advantage of features like TCP Segmentation Offload (TSO) or jumbo frames.

Virtualization Short Take #24

There’s lots of good information flowing around the Internet, and it’s becoming increasingly difficult to sort through all the useless stuff to find the valuable gems. Hopefully, some of the links that I have collected here will prove to be more useful than useless!

VMware HA Problem with Update 3

A problem has been identified with VMware ESX 3.5 Update 3 when using VMware HA and VM failure monitoring. This problem results from a delay in the transmission of a heartbeat from a VM to VMware HA; VMware HA then detects this as a VM failure and restarts the VM. It appears that this problem affects both VMware ESX and VMware ESXi.

Google Apps Doesn't Play Nice with MailTags

One of my most used and most useful applications (add-ons?) is MailTags, by Scott Morrison. It’s an add-on to Mail.app that allows for tagging e-mail messages with keywords, projects, notes, etc., and then saving that information in IMAP headers—if you are so inclined—so that it persists from one IMAP client to another. It’s a fantastic add-on. I highly recommend it.
