Extensive VDI Anti Virtus report released by Project VRC

Today the VRC Team released a new report in a long list of reports regarding Desktop Virtualization. This report goes into detail about how Anti Virus solutions impact you performance for VDI environments. It does not only investigate the traditional methods of doing anti-virus, but also looks at the various offloading (via network and via vSphere vShield API) methods.

Interesting to see is that the vShield offloading method does improve well on Disk i/o, but CPU is not being reduced.

The most important thing is that the document does not just describe the perfomance result with the default behaviour of the most common anti virus solutions, but discusses what kind of optimisations  can be made and what their impact are. So a very useful document for anyone running or building a VDI environment.

New vSphere5 php sample code released

It was a while back I wrote a PHP manual for programming against VMware Virtual Infrastructure 3 (VI3). Assuming most of you run now-a-days vSphere 5.x I finally got around updating the samples 🙂

I am using this code myself for my Raspberry PI analog monitor box for vSphere

You can find my basic explanation in the vSphere 5 PHP guide and the sample files in the download section





Easily copy an ESXi VM to your desktop


I thought I would share with you a simple way to copy a VM from your ESXi servers to your desktop. In my case, my local NAS (qnap) device had a diskfailure, so it is rebuilding its disks for the next 2 days, which slows down IO for my VMs (mainly for my work VM), so I temporary wanted to copy the VM to my local PC and run it in workstation.

Using the build-in download option in the vsphere client sucks. It was super slow. I tried using sftp, again slow (bit faster then vsphere client). My first tought was to google “enable ftp server on esxi”, which I did, and did find ways to get an ftp server installed on my ESXi boxes, but while I opened the ESXi firewall, it still had problems opening a data connection. So after 15 minutes fussing with that I quit that road.

In the forums about FTP on ESXi I came across posts to use Veeam FastSCP, so let’s give that a try. Turns out that the software does not exists anymore and is integrated in a 500mb install of Veeam Backup. I have fast internet, so sure I can download then, but then during the install.. “do you want to install local sql server or use existing??” Hello, I am just trying to copy a single VM, I do not want to screw up my local machine with all that stuff, so cancelled that as well.

Mmm.. what else to do… went googling again and then stumbled on a Freeware bit of software called FreeNFS (http://freenfs.sourceforge.net/) It seems very recent as the note from the developer is from August 14th 2012. It is the most simplest plain NFS server software for windows. its a single executable, click on it, and it runs. done 🙂

So now it was easy. As my local machine suddenly was an NFS server, I add the NFS datastore to my servers and just used a clone VM operation, to thin disk, to my local datastore 🙂

Thank you Lawrence for making this great Free NFS software! Works great with ESXi (version 5).

Heading to VMworld? Are you a geek? Head to booth 1709!!!!!

No worry I am not selling you anyone’s products, but this is a chance you do not want to miss. Veeam is having an awesome competition on their VMworld booth!! A chance to win a DREEAM LAB!!!
– 2 HP ProLiant Servers with memory upgrades
– NETGEAR ReadyNAS storage system with SSD storage
– HP V1410-16G Ethernet switch
…and Microsoft, VMware and Veeam subscription for 1 year!

WOW.. I should be writing, DO NOT go to the VEEAM booth, because I want to win this price, and yes for sure I will be participating in it 🙂 I need a nice upgrade of my home server lab.

Way to go veeam!

2012 List of ways to go for FREE to VMworld

I guess it is time again to start building a list of ways to go for free to VMworld. Every year some vendors have competitions and give-aways for free tickets and even sometimes with free travel.

First to start this year is Veeam. Just by filling in a simple form you can participate in their raffle. It is ‘just’ for the ticket of VMworld, so travel and hotel you need to pay yourself. Competition ends April 18th!

Also VMware is having a competition. Create a video that shows how you are using VMware and you can win a free TRIP (flight plus hotel) to VMworld 2012.


Veeam free pass competition (ends August 9th, 2012, ticket only)

Vkernel session voting competition (ends June 11th, ticket only)
Veeam free pass competition (ends April 18th 2012, Ticket Only)

Create a video for vmware (end April 30th 2012, FULL Trip and 2x Conference passes)



Keep checking this page as I will add any other competitions to this list





Network Acquisitions are hot :-)

Well well, what is going on in the virtualization landscape. I guess more compute virtualization challenges are solved, so it is up to the next challange, network virtualization. Today IP addresses really pose a big problem in creating an agile environment, as it represents both identity and location.

To help start solving some of these network challenges, VMware and Oracle both announced big acquisitions in the networking space.

VMware will acquire Nicira, who is specialized in software-defined networking. Oracle will acquire Xsigo, who as well is specialized in software-defined networking 🙂

More about both deals:
VMware press release
Oracle press release

Is it a coincidence that both virtualization players are getting into software defined networking? Of course not, as I said, most problems around compute virtualization are solved today, while networking is still very much old-school. If we want environments where virtual machines can move from on-premise to off-premise, from one datacenter to another, if we do not want a 1000 cables sticking out of our highly consolidated servers, we need to get the networking on the virtualization bandwagon 🙂

When both companies will integrate these solutions into their stack it will truely be a win for all their customers, who will gain a lot of networking flexibility because of it.

There is progression for Oracle VM -> Gartner releases new Magic Quadrant for x86 Virtualization

Gartner just released an updated Magic Quadrant for x86 Virtualization, and I am happy to read (as I am Oracle Employee) that Oracle is on the way up 🙂 Sure VMware is still leading the pack, followed by Microsoft, but Gartner is seeing customers more often evaluating alternatives to prevent lock-in with VMware.

According to Gartner: “There has been growing interest during the past year in competitive evaluations and creating a separate virtualization footprint with a different technology — typically Microsoft Hyper-V, although Oracle VM use is also growing among VMware customers.”
