VMware Tools Upgrade Execution Aborted

I was doing a vSphere 5.0 to 5.1 upgrade in my home lab tonight and ran into a small issue with upgrading VMware Tools on a Linux VM.   During the install I received an error message 'Unable to create symlink "/etc/cups/ppd/VMware_Virtual_Printer.ppd" pointing to file "/usr/lib/vmware-tools/configurator/thinprint.ppd".  Execution Aborted.' It seemed that CUPS was already present on the server I was upgrading - CUPS is an open source software for modular printing in Unix-like systems.  VMware tools leverages CUPS for ThinPrint / Virtual Printers in Linux systems.  Because the /etc/cups … [Read more...]

VMware View Persona on DFS – Replication Considerations and Issue

I'm presenting this week at the Boston VMware User Group (VMUG) conference on 'What You Didn't Know That You Needed To Know Before Implementing VMware View'.  If you are in the Boston area I hope to see you there! My session abstract is as follows: Don’t be caught unprepared when you make the move to virtual desktops!  This session will provide attendees with an overview of how VMware View integrates with your existing infrastructure, Windows images, applications, and processes.  Building on Clearpath’s experience in implementing VMware View for customers of many sizes in a variety of … [Read more...]

ESXi 5 Won’t Boot From USB

I've been upgrading my home VMware lab to vSphere 5.1 today and ran into an issue that I thought I would share.  I had previously written about my home lab environment - I run HP xw8600 workstations, and because I'm using SATA disks behind a SAS controller they are being seen as 'remote' disks to the ESXi installer.  This means that I need another type of disk that will be seen as a 'local' disk so ESXi can create a scratch partition.  A USB thumb drive was the answer, but not without issues. When I installed ESXi 5.0 on the thumb drive, the install completed without problem, but after the … [Read more...]

Home Lab ESXi Install Problem on HP xw8600 with LSI1068

I recently finished a big basement remodel project (gutted it and started from scratch!), leaving me with a new, bigger office space.   The Townsend Family Director of Standards and Practices (a.k.a. She Who Must Be Obeyed, a.k.a. my wife) thinks she's got a nice new space to do some work in, but I've got better plans! My VMware Home Lab reborn!  I started the rebuild tonight with a pair of HP xw8600 workstations.  They are a nice system for a home lab - dual-socket CPU (Intel Xeon 5400 quad-core series), up to 128GB RAM, 14 channels of on-board LSI 1068 SATA/SAS RAID Controller, PCIe x16, … [Read more...]

Using a CD/DVD drive in VMware View

I've had several people ask me about using CD/DVD drives on VMware View virtual desktops.  Specifically, Can I use a CD or DVD drive with VMware View Desktops? Why doesn't the CD or DVD drive on my re-purposed PC with the VMware View Client pass through to the View desktop? How can I make a CD or DVD drive work on my View Desktop? Are there specific CD/DVD drives that are supported on VMware View? How can I present a CD image (.ISO) to all View Desktops? CD/DVD Devices in a View Environment - What works, what doesn't? First, the bad news.  When using PC over IP (PCoIP) as the … [Read more...]

vSphere 5 Networking Bug #2 Affects Management Network Connectivity

On Wednesday, I wrote about a VMware vSphere 5 networking bug that caused issues with iSCSI networking.  That bug, described in VMware KB 2008144 caused vmk traffic to be sent over the unused vmnic uplink in a team where there is an unused uplink and an explicit failover policy present.  See the diagram below to better understand what was going on there…. The second bug vSphere 5 networking bug I experienced was similar to the first: traffic was sent out of an unexpected interface after upgrading to ESXi 5.  This particular bug surfaced while troubleshooting my iSCSI bug (because why … [Read more...]

vSphere 5 Networking Bug Affects Software iSCSI

Update 1: This issue was fixed as of 3/15/2012 in ESXi 5.0 Update 1 per the original knowledge base article: VMware KB 2008144. To download ESXi 5.0/vCenter Server 5.0 Update 1, see the VMware Download Center.  Update 2 (Nov 7 2012): While VMware says the issue was fixed in vSphere 5.0 Update 1, I have not found this to be the case.  I've had several environments where the bug was still present, and in some cases this nasty bug still appeared when implementing the Failback = NO setting on the vSwitch.  Additionally, setting Failback = No may cause some other problems - see my update here … [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...]

HA Errors after vSphere 4.1 Upgrade

I recently ran into an issue with one of my vSphere clusters after upgrading from vSphere 4.0 to vSphere 4.1 (with ESXi 4.1 and vCenter 4.1).  After the upgrade, I attempted to enable VMware High Availability (HA) on the upgraded cluster.  Each of the ESXi hosts in the cluster appeared to have been properly configured for HA (as observed in the 'Recent Tasks' pane of the vSphere Client).  Despite having appeared to configure HA correctly, I found that each host in the cluster was displaying an error on the Summary tab of the vSphere Client that read 'Error <date> <time> HA agent on … [Read more...]

High CPU Ready, Poor Performance

**Update** January 2013: You've probably found your way here by doing a search for 'High CPU Ready in VMware' or something to that effect.  Welcome, I'm glad you're here.  Give this article a read as it still has relevant content, then check out this newer post on CPU Ready, with some handy quick reference charts and more detailed info on the condition: http://vmtoday.com/2013/01/cpu-ready-revisted-quick-reference-charts/.  Thanks for reading! --Josh I ran into an issue with a customer today where a VM was performing terribly.  From within the guest OS (a Windows 2003 application server … [Read more...]
