This took me quite a while to track this down so I decided to post a quick article on it.
Symptom: Getting page cannot be displayed errors when attempting to access a virtual machine’s (VM) console while using Safari, Firefox, or Chrome on a mac. This only applies for people using the VCSA (VMware vCenter Server Appliance) and running version 5.5.

After running an update on my Macbook Pro, my linux VMs stopped allowing me to login and would simply crash. I contacted VMware support and they advised that the update, along with Fusion update 5.02, don’t play very well together due to a graphics driver issue. See the short post: http://blogs.vmware.com/teamfusion/2012/11/macbook-air-and-macbook-pro-update-2-0-and-vmware-fusion-5.html.
The workaround requires that you go into Settings > Display and turn off “Accelerate 3D Graphics”. While this fix works just fine, it hampers your ability to work in the Linux VM due to the fact that you can’t resize the VM’s work area.

I ran into this error the other night and wanted to make a quick post on it while installing VMware tools into Backtrack Linux.
Unable to create symlink “/etc/cups/ppd/VMware_Virtual_Printer.ppd” pointing to file “/usr/lib/vmware-tools/configurator/thinprint.ppd”.
There’s a really quick solution to this. Backtrack (5 R2) has cups installed by default so that’s not the problem, but for some reason the tools can’t create the ppd directory. Create the ppd directory in /etc/cups manually and you should be good-to-go. This occurred with VMware tools 8.8 and the KDE 64-bit build of Backtrack.
Good luck and hope this helps someone get a quick fix.
I recently found a feature that allows you to quickly migrate the management network from a Distributed Virtual Switch (dvSwitch) to a vStandard Switch (vSwitch). It’s really simple actually. Just log on to a host physically or via iLO, not through the vSphere Client, and select “Restore Standard Switch”.

I recently set out to recreate my vCenter installation since I was still running on Windows Server 2003 R2 64-bit and wanted to the set it up on Windows Server 2008 R2. The problem here was that my Management Network was attached to a dvSwitch (Distributed Virtual Switch). I’ll briefly outline the process of how I removed each host (3 hosts in total) from vCenter, attaching the host to the brand new vCenter installation with only about 10 minutes total virtual machine (VM) downtime. This can actually be done with no downtime if planned properly and aware of the possible hiccups.
The new environment is now up and running, and after refining the process (poking around a lot), it only takes about 10 minutes to move each host. This was done on vSphere 5 (moving from vSphere 5 to Update 1).

I’ve been running a vSphere lab of my since ESX 2.x. Over the years, I’ve used both local and NAS based storage with varying degrees of satisfaction with the results. In the case of NAS storage, which is required since I can’t afford a SAN, I looked at Synology devices over the last year trying to gain the motivation to make the investment.
Needless to say, I dove in with both feet, and maxed out a Synology DS1511+ with 3TB drives. I purchased my Synology DS1511+ from SimplyNas with the drives included, including their burn-in testing, and I haven’t looked back. The device has been up and running since October 2011.

VMware is distributing a limited usage vCloud Director virtual appliance to facilitate and support evaluation of the product. I wanted to stand it up in my lab as a test-bed and to get to know the product better, but after checking into it, it’s not just the eval licenses that will expire. The http certificates will also expire within 60 days of the certificates being generated since it uses the Java ‘keytool’ utility and it’s configured to. As a VMware partner and I have access to licenses to extend the life of the appliance but due to my environment, I cannot work with expired certificates.

I’ve been using a few Iomega StorCenter IX4-200D’s as storage targets for vSphere 4 ESXi and have been a little disappointed at the performance. This disappointment really only comes when VMs are booting, I’m using Storage VMotion, or consolidating snapshots. For the price point, it’s still a great piece of equipment and I can honestly say that I’ve had 17+ active VMs running off the unit with no problem once the VMs are up and running. Keep in mind this is a lab implementation and those VMs weren’t under heavy utilization.
I’ll keep this post updated with anything else I come up with or that is submitted in comments.
Edited 10/23/2011 – No longer recommending use of NFS as a vSphere target on this unit.

I’ve been using an Iomega IX4-200D as a storage target for vSphere and have to say that for the most part it works well. I’ve used it both as an iSCSI target and as NFS storage.
You can and should expect it to suffer typical storage performance issues. It runs on 4 hard drives, mine in a RAID 5 array which is not the most performant, but best in case of disk failure and who wants to lose VMs. It’s still a limited set of spindles to work with and keeping that in mind will save you troubles down the road.
At one point, I had 17 VMs running on a single IX4-200D.
Still interested? Keep reading…
