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...

Building a driver library in VMware Horizon Mirage

Here’s a guest post by Robert Tindall who explains the process one would go through to build a driver Library in Horizon Mirage. This is commonly done when working with Horizon Mirage Base Layers, Restores, and Reverting to snapshots. the following guides you through the process of extracting drivers from the manufacture and gives examples of how you can logically structure your device drivers folders for that manufacture, Model, OS Type etc. To add a driver to your driver library, we suggest you download the driver from...

VMware Horizon View 5.2 Feature Pack 2 released

VMware Horizon View 5.2 Feature Pack 2 includes the following new features: Flash URL Redirection - Customers can now use Adobe Media Server and multicast to deliver live video events in a virtual desktop infrastructure (VDI) environment. To deliver multicast live video streams within a VDI environment, the media stream should be sent directly from the media source to the endpoints, bypassing the virtual desktops. The Flash URL Redirection feature supports this capability by intercepting and redirecting the ShockWave Flash... [Lire la suite]

Multiple vCenter Servers, SSO, and How To Design for Failure

Internally within my company, there is usually a lot of discussion about how a customer goes about managing multiple vCenter servers. With the vSphere 5.1 addition of Single Sign-On (SSO), it dramatically complicates the design itself. This topic won't mean much for SMBs because you should be pretty well off with a single vCenter and SSO instance. This is primarily going to be focused on large enterprise designs.   WARNING::: these are MY design considerations and recommendations, use at your own risk. All depicted... [Lire la suite]

Updating SSL certificates on View Connection servers

While playing with SSL certs on View servers I found one of my Connection servers would start all of its services, but not start listening on 443. Note that netstat can be used to determine if something listening on 443: C:\Users\administrator>netstat -ano |find "443" TCP 0.0.0.0:443 0.0.0.0:0 LISTENING 3096 TCP 0.0.0.0:8443 0.0.0.0:0 LISTENING 3320 TCP [::]:443 [::]:0 LISTENING 3096 TCP [::1]:443 [::1]:56154 ESTABLISHED 3096 TCP [::1]:443 [::1]:56155 ESTABLISHED 3096 TCP [::1]:56154 [::1]:443 ESTABLISHED...

VMware Knowledge Base (KB) - Linux 2.6 kernel-based virtual machines experience slow disk I/O performance (2011861)

If you're using Linux 2.6 kernel-based virtual machines and you're experiencing slow storage performance as compared to physical hosts, the might be a problem with the I/O Scheduler. As of the Linux 2.6 kernel, the default I/O Scheduler is Completely Fair Queuing (CFQ). The default scheduler will affect all disk I/O for VMDK and RDM-based virtual storage solutions. In virtualized environments, it is often not beneficial to schedule I/O at both the host and guest layers. --> The rest is on the blog... [Lire la suite]

Be carefull with VMware SSO Master password bug

This week I installed a fresh vSphere 5.1 Update 1 environment and I wanted to configure it will real world certificates to get rid of all those “Do you really really reeeeeally accept this insecure website” messages. Using the VMware SSL Certificate Automation Tool I generated all the new certificates and then started changing the certificate on the VMware SSO server. When doing this, you’ll be asked for the Master password. Since I learned a while ago in a very painful way that the Admin@System-domain password is not equal to... [Lire la suite]

Cool Tool: VisualEsxtop

My ESXTOP page is still one of the most visited pages I have, it actually comes in on a second spot just right after the HA Deepdive. Every once in a while I revise the page and this week it was time to add VisualEsxtop to the list of tools people should use. I figured I would write a regular blog post first and roll it up in to the page at the same time. So what is VisualEsxtop? VisualEsxtop is an enhanced version of resxtop and esxtop. VisualEsxtop can connect to VMware vCenter Server or ESX hosts, and display ESX server stats... [Lire la suite]
