VMware just announced a new addition to their vCloud product family; vCloud Integration Manager.

vCloud Integration Manager was developed to provide a simple and standardized way for service providers to provision vCloud Director, vShield and vSphere in order to more quickly get new customers up and running on a cloud service. Until now, service providers either had to do these tasks manually, or redirect valuable software development resources to writing undifferentiated “glue code” and/or automation scripts.

Integration Manager reduces operational costs by automatically stepping through the configuration process for vCloud Director to set up Virtual Data Centers, virtual networks, administrator … Read more


Twitter is one of the webservices I deeply admire; simple, easy and scaled to the heavens. They did a review of 2011 with statistics that reaffirm that scalability. A few examples:

  • UEFA Champions League: 6,303 tweets per second
  • MTV VMA: 8,868 tweets per second
  • Steve Jobs’ passing: 6,049 tweets per second

Check the entire list and other 2011 highlights here: http://yearinreview.twitter.com/en/tps.html

A lot of people are saying the VCAP4-DCA and VCP5 are hard to pass. After taking the VCAP4-DCA late October and the VCP5 late December, I was wondering why there are so many warnings; passing didn’t seem too hard. Maybe it’s the practical vs. theoretical clubs, but if you administer an enterprise or service provider VMware environment using several basic techniques like HA, DRS, network or fiber-channel storage, both are really doable.

Either way, to pass these exams, you definitely need to have handson experience. If a test environment is not an option, explore on the environment you do have … Read more


When installing various VMware products that link into vCenter (vShield, vCloud Connector, vChargeback, I could go on..), you often have minimal control over what URL is actually used to browse to the plugin and you usually can’t change it later on. This can screw up your SSL certificate plans.

After a little digging, I found these tables in the SQL database:

– VPX_EXT_CLIENT
– VPX_EXT_SERVER

Both have a field called ‘URL’ which has the URL (doh) to the plugin.

Two things; this is not supported by VMware and could break something. I hasn’t on my setup, but it might on … Read more


A love for Apple’s OSX and computing devices brings some side effects. One of them is that you’re stuck with VMware Fusion which is way behind it’s Windows counterpart, VMware Workstation. Fusion cannot import .ovf VMs, just .vmx VMs. In my case, I needed to convert the vSphere Management Appliance to a VM that could run in VMware Fusion.

It took me a while to this neat tool: http://communities.vmware.com/community/vmtn/server/vsphere/automationtools/ovf – ovftool is a utility that can convert virtual machines between certain formats.

Once you have it downloaded and installed, you can use the commandline tool to convert the .ovf to … Read more


When you’re like me, you just go ahead and install stuff without taking the time to read if the software you’re installing can be upgraded later. Dive head first. 😉

Often with beta software, an upgrade path to a release build is lacking or problematic. Same goes for vCloud Director 1.5 beta to the release build of 1.5. When I upgraded to the release build, I did so without ‘Unpreparing’ the ESXi hosts that were being used by vCloud Director. That causes some problems when you want to link a new vCloud Director to these ESXi hosts, as the vCloud … Read more


For some reason a Cisco ME3400 doesn’t have both IPv4 and IPv6 routing enabled. Still wondering why, but this is how you enable it:

 

conf t
sdm prefer dual-ipv4-and-ipv6 routing
exit
wr mem
reload
