Due to the popularity of the “Mythbusters Goes Virtual” session and survey results, it will be repeated Thursday at 12:30 the session it will take place in San Polo 3404.
When you run across Mythbusters Goes Virtual, keep in mind I will guarantee that after attending this session, you will take your notes and change a thing or two in your own data-center – promise :-) Please join Mattias Sundling and Eric Sloof Thursday at 12:30
Some things never change, or do they? vSphere is getting new and improved features with every release. These features change the characteristics and performance of the virtual machines. If you are not up to speed, you will probably manage your environment based on old and inaccurate information. The vMythbusters have collected a series of interesting hot topics that we have seen widely discussed in virtualization communities, on blogs and on Twitter. We’ve put these topics to the test in our lab to determine if they are a myth or not.

In this video you can see the PowerCLI hero coming to the rescue when Luc Dekens got into trouble.
VMware is rolling out new VCP upgrade paths to promote vSphere 5 training as a way to upgrade from VCP 3 to VCP 5. Listed below are the key points on the new upgrade paths:
- VCP 3’s can take the What’s New 5 ILT to qualify to take the VCP 5 exam
- Upgrade path is valid until Feb 29th, 2012
- After Feb 29th, VCP 3’s will have to take ICM 5 to qualify for the VCP 5 exam
- Students in What’s New 5 ILT classes will receive access to the What’s New 4 eLearning to assist them in transition to vSphere 5
- Students do not have to take the eLearning course to qualify for the upgrade path
- Students who have taken a VCP 4 qualifying course, can attend the WN 5 ILT to satisfy the VCP 5 training requirement
- The upgrade path involving taking WN 4 to achieve a VCP 4 and then follow the VCP 4 to 5 upgrade path is still valid
Join us for our very first VMware ESXi™ Quiz Show, where teams of vExperts and VMware engineers will match expertise on technical facts and trivia related to VMware ESXi and related products. We will cover topics related to ESXi migration, storage, networking security and VMware products. As an attendee, you will get to see the experts battle each other. For the very first time at VMworld, you will decide who leaves the stage as a winner: The audience gets 40 percent of the vote.

VMware has filed an intresting IETF internet draft.This document describes Virtual eXtensible Local Area Network (VXLAN), which is used to address the need for overlay networks within virtualized data centers accommodating multiple tenants. The scheme and the related protocols can be used in cloud service provider and enterprise data center networks.
VXLAN: A Framework for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks.

I’m very excited about this year’s VMworld conference to be held in Las Vegas at the 29th of August 2011. Not only because it’s the first time I’m attending as a speaker but also because I’ll try to capture all the excitement in and around the Las Vegas Venetian hotel with my new HD Video Camera. I’ve created a short teaser trailer. The cool thing about this trailer is that the voice over is done by Jeroen van Inkel. He’s a famous Dutch DJ who created this jingle for me when I was the host at my own weekly radio show called the Twilightzone years ago. Hope you enjoy it and see ya in Las Vegas.

This video will show you an new vSphere 5 feature which enables you to get access to the Direct Console User Interface (DCUI) through SSH instead of the ESXi physical console. Only users that are assigned the Administrator role can log in to the Direct Console User Interface (DCUI). To allow access to the direct console, add the user to the local administrators group. Enabling or disabling lockdown mode affects which types of users are authorized to access host services, but it does not affect the availability of those services. In other words, if the ESXi Shell, SSH, or Direct Console User Interface (DCUI) services are enabled, they will continue to run whether or not the host is in lockdown mode.
Configure Lockdown Mode
To increase the security of your ESXi hosts, you can put them in lockdown mode. When you enable lockdown mode, no users other than vpxuser have authentication permissions, nor can they perform operations against the host directly. Lockdown mode forces all operations to be performed through vCenter Server.
When a host is in lockdown mode, you cannot run vSphere CLI commands from an administration server,vfrom a script, or from vMA against the host. External software or management tools might not be able to retrieve or modify information from the ESXi host.
The root user is still authorized to log in to the direct console user interface when lockdown mode is enabled. Enabling or disabling lockdown mode affects which types of users are authorized to access host services, but it does not affect the availability of those services. In other words, if the ESXi Shell, SSH, or Direct Console User Interface (DCUI) services are enabled, they will continue to run whether or not the host is in lockdown mode.

vSphere High Availability greatly simplifes virtual machine provisioning, resource allocation, load balancing and migration while also providing an easy-to-use, cost-efective high-availability and failover solution for applications running in virtual machines. Using VMware vSphere 5.0 and VMware HA helps eliminate single points of failure in the deployment of business-critical applications in virtual machines. It also enables you to maintain other inherent virtualization benefts such as higher system utilization; closer alignment of IT resources with business goals and priorities; and more streamlined, simplifed and automated administration of larger infrastructure installations and systems.

With this in the back of my mind the urge to solve it grew by the minute and it almost became an obsession to find a working solution. A few days ago we cracked it! And it works like a charm.
In a nutshell:
- USB targets are not supported by default (we fixed this by disabling the check for it)
- The minimal target size should be 5.1GB (we scaled it down to 3.7GB so SD-Cards are supported)
- The SCRATH partition of 4GB (also scaled that one down to 2 GB)
- VMFS grow partition (VMFS of USB?? Neah….. isn’t going to fly so we removed it completely)
Replace you ienviron.vgz with this file (http://www.screencast.com/t/pusv1KGq3) and happy installing. If your to curious and want to know the exact modification: Unpack the file and search/grep on “ernst” in /usr/lib/vmware/weasel/* and /usr/lib/vmware/weasel/scripted/
If you are using the “PXE manager”, modify the “kickstart” part so that you don’t use Local or Remote but instead use device driver. As device driver you enter usb-storage. Oh…. just one more thing: VMware support urged me to say that this hack is not supported by VMware! So this is a non-supported but very welcome hack. :-)

The new resource pools can be defined at the Distributed Switch level by selecting the resource allocation tab and clicking on new network resource pools. After a new network resource pool is defined with shares and limits parameters, that resource pool can be associated with a port group. This association of a network resource pool with a port group enables customers to allocate I/O resources to a group of virtual machines or workloads.

NetFlow is a general networking tool with multiple uses, including network monitoring and profiling, billing, intrusion detection and prevention, networking forensics, and SOX compliance. NetFlow sends aggregated networking flow data to a third‐party collector (an appliance or server). The collector and analyzer report on various information such as the current top flows consuming the most bandwidth in a particular virtual switch, which IP addresses are behaving irregularly, and the number of bytes a particular virtual machine has sent and received in the past 24 hours. NetFlow is a mature technology, developed by Cisco, that is widely supported by third‐party collectors. NetFlow enables visibility into virtual machine traffic in a virtualized datacenter.
ManageEngine NetFlow Analyzer is a web-based bandwidth monitoring tool that collects NetFlow data exported from routing devices, and uses it to analyze and report on IP traffic across the network. With instant reports on top applications, protocols, conversations, and hosts, NetFlow Analyzer gives you valuable insight into bandwidth usage in your enterprise without the complexity and expense involved in a traditional WAN analysis setup.

Port mirroring is the capability on a network switch to send a copy of network packets seen on a switch port to a network monitoring device connected to another switch port. Port mirroring is also referred to as Switch Port Analyzer (SPAN) on Cisco switches. In VMware vSphere 5.0, a Distributed Switch provides a similar port mirroring capability to that available on a physical network switch. After a port mirror session is configured with a destination—a virtual machine, a vmknic or an uplink port—the Distributed Switch copies packets to the destination. Port mirroring provides visibility into:
• Intrahost virtual machine traffic (virtual machine–to–virtual machine traffic on the same host)
• Interhost virtual machine traffic (virtual machine–to–virtual machine traffic on different hosts)
The port mirroring capability on a Distributed Switch is a valuable tool that helps network administrators in debugging network issues in a virtual infrastructure. The granular control over monitoring ingress, egress or all traffic of a port helps administrators fine-tune what traffic is sent for analysis.
Port mirror configuration can be done at the Distributed Switch level, where a network administrator can create a port mirror session by identifying the traffic source that needs monitoring and the traffic destination where the traffic will be mirrored. The traffic source can be any port with ingress, egress or all traffic selected. The traffic destination can be any virtual machine, vmknic or uplink port.
