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.

VisualEsxtop can connect to VMware vCenter Server or ESX hosts, and display ESX server stats... [Lire la suite]

Reporting on RPO Violations From vSphere Replication

A commonly requested thing that people ask for from vSphere Replication is more consolidated reporting.  You can set alerts in vCenter to key off of various things that surface from vSphere Replication, but it is not exactly a consolidated list when doing so.  What people are looking for is a common interface to pull together *just* vSphere Replication alerts for things like RPO violations. My good friends and colleagues Alan Renouf and Lee Dilworth have identified a really elegant way to pull this... [Lire la suite]

Symantec Endpoint Protection Integration with VMware Horizon View – Part1

In one of my recent VDI projects I was working with Symantec Endpoint Protection as the choice of AV solution.

I worked my way across the design and implementation by reading various whitepapers both by VMware and Symantec. This prompted me to work on a series of blog articles which covers the Symantec SEP integration with... [Lire la suite]
