IP Change

As Froos announced earlier we moved to a new IP address today. It seems that the site is up and running fine but it is possible that some folks get a “host not found” due to DNS record replication. We hope all will be updated as soon as possible but this is beyond our influence, so please be patient.

- update -

It seems most dutch ISPs have replicated the DNS records correctly already, so you should get the page there. Oversees it might take a wee bit longer. I hope that it will be fully replicated by tomorrow evening.

Cheers,

Low cost shared storage for test/home lab

A few weeks ago I attended the ‘What’s new in VMware vSphere 4‘ course given by Eric Sloof. Eric pointed us to a very nice and cheap shared storage solution from Iomega which he also uses in his home lab, the Iomega Storcenter ix-series.

I have been scouting the local hardware vendors for the Iomega ix2 but I could decide to go for the cheaper 1TB or the more expensive 2TB version. Today I was browsing through the VMware HCL when I remember the dilemma and was wondering if VMware even knew/supported the little Iomega storage box. And what do you know ………… the Iomega ix-series is on the VMware HCL!

The Iomega StorCenter ix2 and the ix4-100 are supported for all versions of VMware ESX 3.5 and the larger rack mountable ix4-200r is even supported on ESX 4.0 as NAS or iSCSI.

So I will be heading for the shops to get my own home shared storage solution.

The Iomega StorCenter ix is available in the following configurations:

Type Capacity List price
Iomega StorCenter ix2 1 TB € 299,-
Iomega StorCenter ix2 2 TB € 419,-
Iomega StorCenter Pro ix4-200r 2 TB € 1.844,-
Iomega StorCenter Pro ix4-200r 4 TB € 2.141,-

Cisco Nexus 1000V released

Last night I received an e-mail from Cisco thanking me for my work in the Nexus 1000V beta program and announcing the availability of the final product.

For those of you that don’t know the Cisco Nexus 1000V, it is a pure software implementation of a Cisco Nexus switch which can be used in vSphere 4. It resides on a server and integrates with the hypervisor to deliver VN-Link virtual machine-aware network services.

The Cisco Nexus 1000V switch takes advantage of the VMware vSphere vNetwork Distributed Switch framework to offer tightly integrated network services as part of both a server virtualization strategy and a broader data center virtualization strategy. In addition, the switch provides operations and management consistency with existing Cisco Nexus and Cisco Catalyst switches.

Cisco VN-Link and the Cisco Nexus 1000V switch provide server virtualization technology to help ensure consistent, policy-based network capabilities to all physical or virtual servers in a customer’s data center.

Enterprise Hypervisor comparison (updated 04-06-09)

April 25th we published our Enterprise Hypervisor comparison and we got very positive comments on it. A few people were kind enough to provide us feedback so we could improve the document, thanks for that.

I collected all comments and feedback and created version 1.3 of our Enterprise Hypervisor comparison which can be found here.

Again, feel free to contact us when you have feedback for us so we can improve the list.

Upgrade VMware View 3.0 to 3.1

This morning I told you that VMware had released VMware View 3.1 and that I would upgrade our 3.0.1 installations to 3.1 as soon as possible and let you know how the improvements work out for us. Well, it is time.

After reading the release notes I couldn’t resist and decided to upgrade the View 3.0.1 installation at our own Service Center to version 3.1. Luckily this VDI environment is not in production yet because we are experiencing some problems with Vista customization and performance.

I downloaded all new View software (build 167577) and installed the new View agent software in all templates, installed the new View client on my laptop and installed the new View Connection server on the View virtual machine. The upgrades were very simple and straightforward. So let the fun begin……

VMware View 3.1 released

As you all have seen on VMGuru.nl we’re very busy implementing VMware View solutions. These solutions were based on VMware View 3.0.1 but yesterday evening VMware released the new version of their VDI solution VMware View 3.1.

So what’s new in VMware View 3.1?

  • Performance Improvements – Login times are significantly improved and server utilization is reduced.
  • Automated LDAP Data and View Composer Database Backup – You can now configure automated backup of LDAP data and View Composer databases in View Administrator, enabling disaster recovery.
  • Client Information – Information about the client device that the end user is connecting from is now provided for the desktop session as registry settings. This enables customers to use third party tools or create custom scripts to map local printers to devices. The information available includes the device name, IP address, and MAC address.

Don’t let Microsoft “Quick” on you again

As you may have noticed, we at VMGuru.nl have been extremely busy the last few week. Tons of work accompanied with the right amount of stress, illness and personally the build of my new house. This certainly shows in the amount of article we posted lately.

But I try to keep up-to-date, certainly with the release of vSphere 4. So today I read a great article on vTeardown by E. Horschman which I did not want to keep from you.

The article describes the quick migration feature in Microsoft’s Hyper-V, compares this to the live migration feature in the new version and warns customers on the  ‘Quick’ features provided in the next version of Hyper-V.

In the past Microsoft claimed that their Quick Migration feature was enough and Live Migration, as VMware’s vMotion, was not needed.  In vTeardown’s article you can see how quickly Microsoft changes its opinion as soon as they have finally added the feature themselves.

‘Now that Microsoft has live migration on their Hyper-V roadmap, we’re starting to learn that they never really thought much of Quick Migration themselves.  I heard Mark Russinovich, one of their technical luminaries who gave a talk about Hyper-V R2 futures, actually come out and say what we all knew to be true, “Quick Migration was our first attempt to do a live migration, and to put a nice spin on it, we called it Quick Migration. [...] Even though we said, [...] ‘trust us this is really cool, this is what you want, you don’t want instant, that’s not as good as this, this is quick,  but people didn’t seem to buy that, so we ended up [...] implementing live migration, so that Quick Migration stuff is crap, this is really good.’”  Mark’s honesty got some laughs from the packed session, but it puts us on notice that we should be skeptical when Microsoft tags a feature as “Quick”.

Not very trustworthy in my opinion. E. Horschman agrees and adds a warning to beware of Microsoft’s ‘Quick’ features as they now use the same b*lls*!t motivation on their new Quick Storage Migration feature.

So check out ‘When Microsoft Says “Quick”, Do They Really Mean “Crap”?‘.

vSphere4 GA minus 3 days

We are now 3 days from the day we, VMware enthusiasts, have all been waiting for. The general availability of vSphere 4! According to the information that VMware has published officially goes on sale on Thursday May 21st.

As VMware Premier Partner we received numerous e-mails from VMware with fact sheets, specifications and presentations on ‘What’s new in VMware vSphere 4‘, we even attended the ‘What’s new in VMware vSphere 4‘ course by Eric Sloof a few weeks ago. But so far customers have not been calling or e-mailing me to find out what’s new, were and when to purchase it. Don’t get me wrong, I thinks it’s a great new product with many new interesting features and improvements but our customers are not very interested yet.

I don’t now if this is because of the hypervisor battle going on, the economic situation, their great experience with ESX 3.5 or the release date close to the holiday season?

I’m curious to know what your thoughts are on this issue and if you are experiencing the same situation?

Spaces in LDAP

With one of our deployments of VMware View we had problems with the linked clones. Adding the computer accounts to Active Directory failed everytime. Even after recreating the pool it failed. Computer accounts weren’t created in Active Directory.

After a lot of troubleshooting, logfile reading and consulting with VMware Support a colleague said: Why are you entering spaces in the LDAP path?

Website maintenance

Due to an IP address change at our hosting service this website may be temporarily unavailable during the coming two weeks. We will try to limit the disruption as much as possible. Because of the DNS replication time this may take a maximum of two weeks to sort itself out.

Sorry for the inconvenience,

the VMGuru.nl-crew

The name is Epping, Duncan Epping….

This morning I received a tweet from Duncan Epping, Duncan works at VMware Benelux and is the owner of Yellow-Bricks.com. In the community it was a public secret that Duncan was in the USA to defend his case to become one of the fist VCDX (VMware Certified Design Expert) certified professionals worldwide. And this morning he twittered that he had received his VCDX award at the VMware Award dinner last night.

So Duncan, from the crew of VMGuru.nl, congratulations!

Duncan is the 7th VCDX professional worldwide and what a cool number to have, VCDX007.
From now on you can pick up the phone saying, ‘this is Epping, Duncan Epping;)

Duncan, congrats and enjoy!

Short outage

The site has been down for about an hour or so. Due to a shortage on another server in the rack, the powerbar decided to close down the whole rack for damagecontrol. The cause has been found and the machine removed, so we’re back up and running.

Yes, I hear you all think “why is this important webserver not on HA”.. well.. we’re working on that ;) For the time being, let’s hope it just doesn’t happen again.

Cheers,
Froos

Template customization problem solved

As it is VMware View season I ran into a new problem deploying new virtual desktops in the virtual infrastructure I presented to you in this article.

The people who read it know that the infrastructure serves various clients/customers so I have to deploy various virtual machines varying from Windows XP to Vista. Last week I deployed a virtual machine and asked a colleague to install all software and tools needed for this client site. It took him a day to get the virtual machine ready, after that I tweaked and tuned it to run in a VMware View environment and converted it to a template.

When I created a desktop pool with this template the fun started. The deployment went great but when the virtual machine powers on, guest customization should kick in and it didn’t. At first I investigated the obvious things, like correct sysprep version, check the customization specification, vmware tools, etc.

VMware View log viewing

With the addition of VMware View your environment gains complexity. Before adding components like vdmimageVMware View or Lab Manager you only have one point of logging in your virtual enviroment, vCenter Server. Now you have to look into the textfiles itself if you want to do some real troubleshooting.
