Pimp My Microserver!

I’m not normally in the habit of posting this sort of thing but I do own a number of these MicroServers and they’re great for home lab use. They may only take up to 8Gb RAM and have single, dual-core chips in them but they don’t eat much power and don’t make much noise. They’re also as “cheap as chips” to buy!

Enough about why I have them. ServersPlus are running a competition of sorts to design a cosmetically pimped up MicroServer. If you submit what becomes the winning design you get the first one of the batch for free.

Submissions have to be in on 11th November and voting runs until 30th November.

Bath vBeers 9th December 2011

As many of you in the VMware community will know, there are regular vBeers events held around the country. (See http://www.vBeers.org for more information about the international phenomenon).

This year, I am arranging a vBeers event in Bath, for anyone and everyone who wants to come and have an early festive celebration in our fair city. I have posted more information on the event on the vBeers.org website – have a look here (http://www.vbeers.org/2011/10/26/vbeers-bath-friday-9th-december-2011/) to see full event information, including location and times etc.

In addition to all the main and additional seasonal attractions of Bath, as an added incentive this event is being sponsored by my company Eduserv (http://www.eduserv.org.uk) who will ensure everyone who attends will be furnished with a beverage of their choice!

If you’d like more information, please leave us a comment or post us a mail or tweet either here or on the vBeers site, and we can get back to you.

Hope to see many of you along.

VMware ThinApp BootCamp

Earlier in the year VMware ran a View 4.6 BootCamp that was well received. As a natural follow-up to that, next week sees the start of a six part ThinApp BootCamp.

Starting on Monday 31st October and running for six business days, the ThinApp BootCamp will see the following videos released, one per day:

  • ThinApp Design Best Practices
  • ThinApp Implementation Best Practices
  • ThinApp Performance Enhancing Techniques
  • Scripting within ThinApp
  • Isolation Modes Explained
  • AppLink Fundamentals

At the end of the BootCamp you can register to download an eBook copy of all of the presentations.

If you’re using or thinking of using ThinApp, this BootCamp is a free and self-paced method of learning more. To find out more, head over to the BootCamp’s page here.

VMware VCP 5 Exam Revision

I have the VCP5 exam in a couple of weeks, and am in the midst of revision. A couple of excellent resources for those going through the same process:

TrainSignal VCP revision videos.

- The Simon Long blog (www.simonlong.co.uk/blog/)

Mastering VMware vSphere 5 book by Scott Lowe.

Update: I have been reading more of Scott’s book and am now deep into Chapter 7: High Availability. Can’t recommend it enough – even if you aren’t taking the exam!

- vSphere Clustering 5 Technical Deepdive book by Duncan Epping and Frank Denneman.

- VMware VCP homepage, including the VCP5 exam blueprint, FAQ, VCP Forum and mock exam.

All these are fantastic resources – use them if you are studying for this exam! Any more useful links? Please post comments and add them to this list of resources……

More on results as I take the exam……

HP ESXi 5.0 ISO: Write Failed Error….

I have recently been building a test lab with HP Proliant servers, and came up with an interesting problem.

The VC was built successfully on a VM on one of the hosts, and the hosts were all built using the HP custom ESXi 5.0 ISO image. Interestingly, the hosts all had disconnection issues and an error in the logs detailing:

- Installing license

- A general system error occurred: Write failed file:/etc/vmware/vmware.lic

After some searching around, I found this post on VMware Communities describing the problem – essentially the host license is unable to be written to and needs to be removed before a valid license can be used:

http://communities.vmware.com/thread/326778

…so I thought I’d summarise the solution. Credit to poster ‘sc_2111@vmtn‘ for the solution as posted, via HP Support.

First, check the license.lic file permissions:

-r–r–r–    1 root     root                 30 Aug 19 13:57 vmware.lic

If they are as above, the fix is required, as the permissions should be ’600′ or ‘-rw——T’.

# esxcli software vib remove -n hp-esx-license –no-live-install

Removal ResultMessage: The update completed successfully, but the system needs to be rebooted for the changes to be effective.

Reboot Required: true

VIBs Installed:

VIBs Removed: Hewlett-Packard_bootbank_hp-esx-license_1.0-03

After Power off:

# ls -l /etc/vmware/vmware.lic-rw——T 1 root root 30 Aug 19 01:41 /etc/vmware/vmware.lic

After Connect to VCenter:

 # ls -l /etc/vmware/vmware.lic-rw——- 1 root root 29 Sep 8 09:34 /etc/vmware/vmware.lic
