[Release] ESXi-Customizer-PS version 2.0

I just released a new major version of my ESXi-Customizer-PS PowerCLI script that greatly simplifies and automates the process of creating fully patched and customized ESXi 5.x installation ISOs using the ImageBuilder snapin.What's new: A new operational mode (-update) allows to update a locally existing ESXi Offline bundle with the latest patch level from the VMware Online depot. This way you can easily bring a vendor supplied ESXi installation ISO (like the HP Customized ISO) to the most recent ESXi patch level. ... [Lire la suite]

How to create shared iSCSI storage for ESXi using StarWind’s iSCSI SAN Software

How to create shared iSCSI storage for ESXi using StarWind’s iSCSI SAN Software In my previous post, I mentioned that I use StarWind Software’s iSCSI SAN software to provide iSCSI LUNs for my home lab.  In this post, I’ll document the process to create a simple shared iSCSI LUN setup.  Using that, one can provide as many LUNs as required to an ESXi setup, possibly with multipathing – very useful if one doesn’t have expensive network storage and virtual appliances don’t seen flexible enough.  I should apologise in...

Using ImageBuilder to make custom ESXi ISO

On a previous post, I’ve write on how build custom ESXi ISO with 3rd part tools. Those tools are not mentioned by VMware so probably are not supported. But you need a custom ISO in order to install ESXi on a host where the network drivers are missing (storage could be not an issue if you install it on a USB/Flash card). The other solutions are use a vendor related custom ISO or the embedded version that probably already include the right drivers. But in order to build your custom ISO you could use the same...

ALERT: Login issue after updating to vCenter 5.1 Update 1

VMware has become aware of an issue that may occur after upgrading to vCenter Server 5.1 Update 1.   Specifically: You are unable to log in using the vSphere Web Client or domain username/password credentials via the vSphere Client. This issue can occur if the specified vCenter Server login domain user account is associated with a large number of domain groups and multiple domains are configured as SSO identity sources. The precise number of groups at which this issue can occur varies due to the nature of Active... [Lire la suite]

vSphere 5.1 Update 1 Released!

VMware has just released the much anticipated Update 1 patch for vSphere 5.1 which includes several updates and bug fixes for both ESXi and vCenter Server 5.1. I highly encourage everyone to review the release notes for the complete list of resolved issues. While going through the ESXi 5.1 Update 1 release notes myself, I noticed a few resolved bugs that I had been following and thought I would highlight a few of them: Reinstallation of ESXi 5.1 does not remove the Datastore label of the local VMFS of an...

Easily Rescan All ESXi Host Storage

I'm what you might call a contradiction. I'm definitely not a fan of the repetitive task, but am also coincidentally too lazy to learn how to script this very same task. Sometimes I luck out and a quick Web search will point me in the right direction, or other times my laziness takes me to built-in functions that can help me out just as well. The vSphere Client (and Web Client!) have helped me avoid scripting one more time! Whew! The repetitive task of the day is adding a VMFS volume to a vSphere cluster. Before I found this little...

Understanding ESXi Patches – Size & Patch Bundles

Patch management for ESXi is very different compared to traditional operating system patches, where incremental updates are made to the base operating system and thus increasing the disk footprint for each patch update. For the ESXi hypervisor, when a patch is applied, the entire ESXi image also known as an Image Profile is replaced. This means that each time you patch or upgrade your ESXi host, you are not adding on top of the original installation size. As part of the ESXi architecture, there are two... [Lire la suite]

ESXi 5.1 Free – how to run nested Hyper-V

How-to run nested Hyper-V 2012 Server on latest version of ESXi 5.1 If you want to test the latest Microsoft Hyper-V running as a VM on ESXi 5.1 free version, you might run into a following error: “Hyper-V cannot be installed: A hypervisor is already running.” when trying to install the Hyper-V role. In ESXi 5.1 free version the tweak slightly changed (compared to ESXi 5.0) and it’s much easier to install the Hyper-V role, to actually enable Hyper-V as a VM with the possibility to run second level nested 64bit VMs inside of that...
