In a recent blog post I wrote about my efforts to implement IPv6 in my hosted virtual lab. This is working all fine for my VMs now, but to complete the picture I also wanted to configure IPv6 for the public management / VMkernel interface of the physical ESXi host (Please note: you do not need IPv6 support for the management interface if you just want to use IPv6 with your VMs - these are really two different networks!)
To come to the point: I am currently not able to make my ESXi host use IPv6!

HP releases Service Pack 2013.02.0 for ProLiant and updated software for ESXi 5.x
Yesterday HP released version 2013.02.0 of their Service Pack for ProLiant (SPP). This is a (bootable) ISO file that contains the latest firmware and driver packages for ProLiant servers. What's new:
On http://vibsdepot.hp.com/ there are updated Offline bundles and drivers for VMware ESXi 5.x available (see the feb2013 directory for downloads).
The latest versions of the HP customized installation ISOs are available for ESXi 5.0 U2 and ESXi 5.1. As usual they do not include the latest ESXi patch level. For instructions on how to build a custom ISO with the latest VMware patch level and the latest HP stuff please see this blog post.
I have updated my HP & VMware Links page to include the new releases.
- Added online deployment of a select set of firmware components to systems running VMware ESXi 5.x (that means you can now deploy Smart Components through HP SUM!)
- Support for new hardware devices and OS versions
- Support for PXE booting the SPP ISO
- Updated HP Smart Update Manager (SUM) to version 5.3.5
Additional information:
- Full release notes
- February 2013 VMware FW and Software Recipe (Recommended Firmware and software versions)

Implementing IPv6 in a hosted virtual lab
Did you know that the IPv6 standard was drafted more than 14 years ago, in Dec 1998? Adoption grew very slowly since then, but with today's ongoing exhaustion of IPv4 addresses IPv6 is gaining momentum:
- Almost all important ISPs (Internet Service Providers) and big companies that make business on the Internet already use and support IPv6.
- More an more other companies and institutions look into implementing IPv6 for their Internet-facing services (mainly public web sites).
- All modern Operating Systems have built-in support for IPv6. Many of them (inlcuding Windows 7/8) have it enabled by default.
IPv6 is inescapable. It's here. It's here to stay. It matters. Are you ready?
My ownCloud adventures, Part 2: Certificates and Windows access
This is the second part of my postings about ownCloud, an Open source solution for managing your data in the cloud. The first part covered the installation and initial configuration of the BitNami ownCloud stack virtual appliance. I will continue with explaining how to secure access to your data with SSL certificates and using WebDAV in Windows to access your ownCloud files.
A common misconception about resource pools
In vSphere resource pools are a great way to divide your overall compute resources into multiple independent pools and prioritize resources among different VMs. But before you create and use them you should make sure that you have fully understood how resource pools work, and what effect their settings have. In the vSphere Resource Management Guide there is a long chapter about Managing Resource Pools that describes how to set them up and how they work using some real world examples. And still it looks like this information is not clear enough (or maybe there is just a part missing in the documentation that explains how resource pools do not work), because there are surprisingly many vSphere environments that use them in the following way:
