I´ve men­tioned this ear­lier, VMware hands-in labs going pub­lic in 2012, but finally it seems like some­thing is hap­pen­ing in that regard!

Scott Sauer has announced the avail­abil­ity of “VMware Vir­tual Cus­tomer Labs” (vCL) where he walks us through the setup and deliv­ery of the new vCL offering.

At the moment it´s only avail­able to “selected cus­tomers”, sup­ported by a VMware pre-sales engi­neer, and the num­ber of labs are lim­ited. It´s still a work in progress, and I´m sure great things will come out of this!

Now, how do I get access to it as a part­ner? Also, I won­der what pos­si­bil­i­ties that lies in this with regards to alter­na­tive VCP require­ments?

In a recent arti­cle, VCP 5 cer­ti­fi­ca­tion course dead­line looms over VMware pros both vNinja.net con­trib­u­tors (Chris­t­ian and Ed) are quoted in rela­tion to the VCP 5 cer­ti­fi­ca­tion upgrade dead­line of Feb­ru­ary 29th 2012.

While I can´t speak for Ed, I can clar­ify my own com­ments a bit. The fol­low­ing is a quote from VMware, taken from the arti­cle in question:

That require­ment is in place to main­tain the integrity of the cer­ti­fi­ca­tion. If peo­ple could pass the VCP 5 with­out expo­sure to and hands-on expe­ri­ence with vSphere 5, it would devalue the cer­ti­fi­ca­tion,” a VMware spokesper­son wrote in an email.

While I do see why VMware has that stance, and why they try to keep the exam “real”, my prob­lem is that there is no way for any­one to do the VCP cer­ti­fi­ca­tion with­out class­room train­ing. I don´t mind that VMware has a train­ing require­ment, and I don´t mind that you have to pay for it. What I do have a prob­lem with is that I´m required to sit a 5 day train­ing class. Why not offer an online VCP-prep course that you can com­plete in your own pace, com­plete with a pre-exam test that you can use to val­i­date your skill set? That way VMware can still require a min­i­mum of train­ing pre-exam, get paid for it, and stu­dents can do their train­ing in their own pace and when they have avail­able time for it. Seems like a win-win (bingo!) sit­u­a­tion to me?

As far as I´ve heard the VCP5 exam focuses less on min­i­mum and max­i­mum con­fig­u­ra­tion lim­its than the VCP4 which is a good thing, but at the same time I don´t think the Install, Con­fig­ure and Man­age course by itself is enough to pass the exam, so in essence VMware is already “devalu­ing” their own exam by requir­ing train­ing that does not cover the entire curriculum.

The hands-on require­ment is a good one, and I applaud it, the best way to ensure that would be to turn the VCP exam into a hands-on-lab envi­ron­ment where you get tasks to com­plete, instead of mul­ti­ple choice questions.

Dis­claimer: I have not yet tried to do the VCP 5 exam and I´m only com­ment­ing based on feed­back pro­vided by oth­ers who have.

As far as the time avail­able for exist­ing VCPs to upgrade from VCP4 to VCP5, I also believe the time­frame is too short, and to be com­pletely hon­est I don´t really see why there should be a time limit at all? After all, if you have the VCP4, you pretty much know what you´re in for with regards to the VCP5. Why rush it, and have peo­ple attempt to upgrade before they are ready? Let peo­ple do this on their own, in their own sched­ule, I don´t see how VMware ben­e­fits from enforc­ing a time­frame at all. Unless the moti­va­tion is sell­ing more train­ing, of course.

Votes for vNinja.net and vSoup.net would be greatly appre­ci­ated, but since we´re not affil­i­ated with the Dutch vMaf­fia we promise that you will not have to wear con­crete boots or wake up to a horses head in your bed if you don´t vote for us.

We think.

As Mr. Simon Sea­grave has pointed out, there is a fix avail­able to enable OSX Lion Time Machine sup­port for Iomega IX2 and IX4 NAS stor­age devices.

I decided to take this a lit­tle step fur­ther, and try to upgrade my old (and dis­con­tin­ued) Iomega IX2-200 to the new IX2-200 Cloud Edi­tion firmware.

Ini­tially this was a big fail­ure, as I seem­ingly man­aged to brick my device. It was only respond­ing to pings (so the TCP/IP stack was loaded and work­ing), but I could not bring up the web based man­age­ment tool nor con­nect via tel­net or SSH.

Thank­fully Will van Antwer­pen had inves­ti­gated the firmware upgrade to cloud edi­tion a bit more than I had, and pointed me to the Gen­eral NAS-Central Forums where I found a link to a great HowTo explain­ing the entire process: Upgrad­ing Iomega ix2-200 to Cloud Edi­tion.

As that arti­cle also men­tions, I had to do the process twice to get it to kick in and un-brick my IX2-200 and get it run­ning with the new Cloud Edi­tion firmware.

After con­fig­ur­ing the IX2 with secu­rity and set­ting up Time Machine on the Mac­book Air, Time Machine seems to be run­ning with­out problems.

My new col­league Olav Tvedt asked me if I could test his method of enabling Bit­locker in a VM, on VMware vSphere. Of course, I was happy to oblige.

I fol­lowed the same steps as he did in his Run­ning Bit­locker on a Vir­tual com­puter post, and it worked perfectly.

The only real dif­fer­ence between doing this in Hyper-V and on ESXi, is that the vir­tual floppy drive on ESXi by default doesn’t emu­late an empty floppy. So, in order to mount a vir­tual floppy you need to cre­ate a new floppy image. Thank­fully the vSphere Client can do this for you!

To use the vSphere Client to cre­ate a floppy image you can later mount in a VM, you need to edit a VM’s set­tings. Find the floppy drive, if the VM doesn’t have one add one, close the win­dow and return to the VM set­tings once the floppy drive has been added, and select “Cre­ate new floppy image in datastore: “.

Click on the Browse but­ton and browse to your pre­ferred loca­tion for the floppy image. Name it, and click on Ok.

Click on Ok again to close the VM set­tings win­dow and return to the vSphere Client.

There you go, an empty vir­tual floppy image that you can mount in a VM is now created.

To mount the image, find the floppy drive icon in the vSphere client and select the Con­nect to floppy image on a data­s­tore option.

Browse to the loca­tion where you cre­ated the floppy image, and select it.

Now, the VM has an empty floppy that you’ll need to for­mat before you can use it.

Fol­low Olav’s guide to encrypt the boot drive with Bit­locker, with­out the need for a TPM chip or USB device con­nected to the VM!

And yes, it works as you can see here:

So much for never need­ing a floppy disk again. Oh, and by the way, you can of course do this is VMware Work­sta­tion 8 as well.

Sammy Bogaert has posted a 12 part series called “Build­ing The Ulti­mate vSphere Lab”, which knocks the socks of my pre­vi­ous vSphere 4.x series.

In real­ity this means that my planned series for vSphere 5.x is now can­celled, as there is no need to dupli­cate Sammy’s efforts. Be sure to check the series out!

Yes, this is YAEo­tYP, so if you’ve already read tons of them I apologize.

2011 — My per­sonal view

2011 has been a steam­roller of a year.The vSoup Vir­tu­al­iza­tion Pod­cast got aired the first time, and we’ve recorded and pub­lished 19 full episodes in the inau­gural year. I was awarded the vEx­pert title for the first time, and even got invited to Tech Field Day #6 in Boston.

In addi­tion to this, I wrote a white paper for Veeam, was included in the Server Vir­tu­al­iza­tion Advi­sory Board, joined Rick Vanover for a Veeam Com­mu­nity Pod­cast, and appeared in two video interviews.

One with Mike Lav­er­ick about the #VMTNSub­scrip­tion­Move­ment and one where Eric Sloof ambushed me with a cam­era while vis­it­ing Bergen.

Lots of exit­ing projects were started in 2011, includ­ing my Pow­er­CLI based automa­tion project for ves­sel instal­la­tions, migrat­ing from stand­alone ESX hosts to blade servers (HP c7000 + Vir­tual Connect/Flex10) in addi­tion to the nor­mal day to day oper­a­tions and after 8 years at Seatrans AS, I handed in my papers, mov­ing on to a new role for EDB ErgoGroup.

2011 vNinja.net Statistics

2011 was the first year this site existed, so I can’t really com­pare the traf­fic it has received with 2010, but based on the few months it existed in 2010 the traf­fic increase has been enormous.

2011 Facts


And that’s it for 2011. Per­son­ally 2012 looks even more promis­ing, and hope­fully my expo­sure to more diverse envi­ron­ments should be reflected back on the site as I’m cer­tain it will spur more posts and more inter­est­ing dis­cus­sions. See you in 2012, I think we’re in for a cracker.

One of the last projects I’ve been involved with at Seatrans, is to auto­mate the instal­la­tion and con­fig­u­ra­tion of vSphere ESXi 5 hosts for deploy­ment on ves­sels. I’ve talked a bit about this before, both on vSoup and in Set­ting Up Auto­mated ESXi Deploy­ments where I out­lined my PXE and Pow­er­CLI based instal­la­tion and con­fig­u­ra­tion scheme. Not much has changed since then, except updat­ing the PXE server to offer ESXi 5, instead of ESXi 4 and a lot of work has been put into the script­ing, includ­ing a front-end GUI for the Pow­er­CLI script itself. The end “prod­uct” is now in place for mass deploy­ments for inter­nal use.

The fol­low­ing video shows how the PXE based instal­la­tion works, as well as a run through the now GUI based con­fig­u­ra­tion tool aptly called Seatrans Hyper­vi­sor Instal­la­tion Tool.

The video jumps a bit between two VMs, one run­ning Win­dows Server 2008 R2, that runs the DHCP/PXE ser­vices and the Pow­er­CLI script, and one that gets ESXi installed and configured:

This goes to show that you can cre­ate your own, spe­cial­ized and portable deploy­ment solu­tion with­out requir­ing elab­o­rate net­work con­fig­u­ra­tions or recon­fig­ur­ing of exist­ing infrastructure.

Note: I will not be pro­vid­ing down­load­able ver­sions of the final script at this time. The rea­son for this is quite sim­ple, it’s very spe­cific and tai­lored for a non-generic envi­ron­ment. If I can man­age to find the time, I’ll post a generic ver­sion later but in order for any­one else to uti­lize the Pow­er­CLI scripts I’ve cre­ated, a lot of work is required.

While using Thi­nApp to cre­ate a stand­alone ver­sion of Tweet­Deck 0.38.2, since the newly announced 1.0 ver­sion looks, acts and feels like a 0.1 ver­sion, I posed the fol­low­ing ques­tion on Twitter:

“Hrm, what other apps should i #Thi­nApp while I’m at it?”.

Kevin Kelling imme­di­ately responded with “Doom”.

Nat­u­rally, I decided to give it a go. A quick down­load of ZDoom later, and a quick run through the Thi­nApp Setup Cap­ture later, the fol­low­ing was born (view in full screen for bet­ter viewing):

Thus, DaaS (Doom as a Ser­vice) is born as a concept.

As the title says, it’s been one of my more “pub­lic” weeks ever. Besides my “nor­mal” vSoup engage­ment, this week I’ve also been involved with Mike Laverick’s VMTN Sub­scrip­tion Move­ment Mini­wags to voice some of my views about the #VMTNSub­scrip­tion­Move­ment.

Fair warn­ing: This is video, and please to remem­ber that dur­ing record­ing Movem­ber was near­ing its final phase.

Sec­ondly, I was a guest on the Veeam Com­mu­nity Pod­cast Episode 45 – vSphere 5 Stor­age Pot­pourri.

Third, and last, Search­ServerVir­tu­al­iza­tion posted VMware vSphere Stor­age Appli­ance: Devil’s in the details which also includes some com­men­tary from yours truly regard­ing the VSA.
