Today, at some ungodly hour of the morning, VMware updated two security announcements: VMSA-2008-0017.1 – Was updated to change some CVE numbers VMSA-2008-0016.2 – Was updated to include information about update 3 As last time you can get all security advisories from VMware’s site: http://www.vmware.com/security/advisories/ Technorati : ESX, ESXi, Security, VMware, VMware Security Del.icio.us :

If like me you accepted most of the defaults the first go around when installing VMware’s Update Manager, you may have found yourself in a situation where there is not enough disk space to contain all of the files. Should this happen, and you need to change the location, you can edit the settings XML

I didn’t know this until today, but according to KB 1687 both soft and hard page faults will cause a context switch into the virtualization layer, which in turn causes additional overhead. This was clued in by a VMware engineer looking over a case of horrid performance that we’ve been encountering. Hard page faults involve

After much exploring, I’ve found a nice little PDF that describes the communication flow, and IP port use. This is brought to you by the Virtualization Evangelist VMware VI network communications and port usage diagram
Came across this in my browsing, figured it was worth repeating here for my own future reference: RPMS for VMWare ESX 3.5 Technorati : 3rd Party RPMs for ESX, ESX, ESX RPMs, VMware Del.icio.us : 3rd Party RPMs for ESX, ESX, ESX RPMs, VMware Zooomr : 3rd Party RPMs for ESX, ESX, ESX RPMs, VMware

Despite all of the time you spent planning your virtual machine deployment, inevitably someone will want to make a change to their VM. While some of these may be straight forward, change the CPU allocation, increase the memory allotment, some of these will not be. Say the accounting team had determined they needed 450GB for

So I wanted to talk on best practices for your Service Console, what it’s for, and why and how to make it redundant. As that’s a lot of information, we’ll break it out in some parts. This first part we’ll talk about what the service console is, and what it does. So what is the

Straight from the VMware Security announcement mailing list: http://www.vmware.com/security/advisories/VMSA-2008-0018.html VMware Hosted products and patches for ESX and ESXi resolve multiple security issues. A flaw in the CPU hardware emulation may allow for a privilege escalation on virtual machine guest operating systems. In addition a directory traversal issue is resolved. Read that over again… A flaw

I have a confession to make. It is dire in nature, and will likely surprise most of you. I’m lazy. So much so, that I’m a professional at it. I suppose that sounds pretty bad, and if my boss is reading this (I doubt he is), it’s also quite incriminating, so lets qualify a bit.

I wanted to share some of the various certification resources out there for VMware. It is one of the HOT IT Certifications right now, up there with the CISSP and RHCE, and it’s quite useful as well. At least the class & test were not 100% fluff like some other vendors produce. Right now VMware

So I had typed up this epic intro into this pre-review, but then deleted for the sake of brevity. I received in the mail today, via USPS shipment from Amazon.com, my copy of VMware Infrastructure 3 Advanced Technical Design Guide & Advanced Operations Guide (VI3ATG). The book weighs in at about 2-2.5lbs, and is about

So, this is a bit of old news, and you have likely heard it from no fewer than thirty other places so far, but I feel I need to chime in too. ESX 3.5 update 3 is now available! The release notes mention a pretty cool feature that’s been added, that will help make life

One of the great things about VM’s is how quickly they boot. This however can be a problem when you need to access a bios setting, say to have it boot a cd drive first. In your favorite editor, open your vmx file, and add the following line if it is not already there: bios.bootDelay

Welcome indeed. My hope here is to build a running log(blog) of ideas, best practices, and other useful VMWare information, that can be used both at home for practice, and at work in a professional context.
