VMware Product Updates – April 2013

VMware has released updates to several products over the past couple weeks.  Many of the updates take the version 5.1 products announced at VMworld 2012 to Update 1 (i.e. the first major service pack).  The updates, spanning vSphere (ESXi and vCenter), vCloud Director, vCenter Operations, vCenter Orchestrator, vCenter Site Recovery Manager (SRM), vSphere Data Protection, and the vSphere Storage Appliance, include bug fixes, security fixes, and functionality changes.  Here’s what you need to know about the updates, including a few upgrade bugs that you need to know about before you pull the … [Read more...]

Microsoft KB2661254 and VMware

Microsoft today is pushing an update to Windows via Windows Updates that increases the bit length requirements for RSA certificates.  With this update, Microsoft is requiring RSA certificates to have a key length of 1024 bits.  Some applications do not yet use a 1024 or greater key length and could be impacted by this updated.  Some examples: Internal Microsoft Certificate Authority servers that were built with a less than 1024 key will not start after the update – this will make certification validation for internally generated certs fail (could impact Outlook Web Access, vCenter … [Read more...]

Failed to connect to VMware Lookup Service on VMware vCenter Virtual Appliance

I've been rebuilding my home VMware lab environment recently.  I decided to jump right into vSphere 5.1 with the vCenter Server Virtual Appliance instead of the traditional Windows SQL combo.  Deploying a vApp is much faster and cheaper from a licensing perspective than a full-blown Windows and SQL setup.  After I imported the vCenter Virtual Appliance .OVA,  I logged into the administrative web interface of the appliance (https://vcenterIP:5480) and started to make a few configuration changes.  First up were assigning a hostname, setting the correct time zone, and setting a static IP … [Read more...]

vCenter Crashes After Applying ESXi Patch ESXi410-201010401-SG

My last post described a problem I experienced with VMware HA after upgrading to vSphere 4.1.  Here is my experience with a similar issue after applying the ESXi410-201010401-SG patch to one of my test/dev ESXi clusters.  The patch, released on November 15th and weighing in at a hefty 212MB, fixes a number of issues from Likewise authentication on ESXi hosts to allowing configurable NOOP timout and interval values for faster failover of certain iSCSI arrays (like the DS3300 or MD3000i). The environment where this problem occured has a single vCenter server managing both a production cluster … [Read more...]

Installing PowerPath/VE using VMware Update Manager

I am finishing up an installation of an EMC Clariion CX4 SAN. One of the final steps of the installation is to configure PowerPath/VE on the ESXi hosts. PowerPath/VE is EMC's multipathing extension module for VMware (and Hyper-V), designed to replace the Native Multipathing Plugin (NMP) for increased I/O performance and failover management.  To simplify and automate the installation of PowerPath/VE, I decided to use VMware Update Manager (VUM) to push the extension to the ESXi 4.x hosts in the environment. The process of setting up an additional VUM patch repository to host PowerPath/VE … [Read more...]

vCenter Database Stats Rollup Troubleshooting

VMware vCenter collects performance statistics, tasks and events for historical performance analysis and auditing.  The collection level and retention of performance statistics can be controlled through the vCenter GUI (see Administration | vCenter Server Settings | Statistics).   The level of statistics collection and retention periods can have a dramatic impact on your vCenter Server's performance if not carefully planned and monitored.  In particular, the vCenter database can grow quite large and the database server required to support the increase in statistics increases in size and … [Read more...]

vCenter Client Passthrough Authentication

I started this blog for a couple reasons: 1.) To help you, my readers, with your virtualization projects, and 2.) To help myself by: a.) raising my online profile as an expert in the community, and b.) To give myself somewhere to keep tidbits of knowledge that I find myself going back to look for over and over again. This post is a 2b. I just built up a new laptop and couldn't remember how to set up pass-through authentication on my VI3 Client. A quick Google search gave me the answer, courtesy of Stu Radnidge's post on nothing other than VirtualCenter 2.5 Passthrough Authentication.  This … [Read more...]
