Plain Virtualization

Another high rating of CVSSv3 of 9.8 was released here on VMware Cloud Director appliance. For those not aware, the virtual appliance is a prepackaged virtual machine with added configuration bedded in for easy deployment. This time it is due to authentication bypass vulnerability which allows a user to bypass authenticating on port 22 (ssh) or port 5480 after upgraded to version 10.5 from a previously older version. To resolve this, the updated kb has been released and it provide a script for the workaround to fix this. Do note that this affect only VMware Cloud Director version 10.5 which was upgraded from older version. Not on new deployment or other versions.

One of the many documents that we always refer to for vSphere is the configuration maximum. Back in the days, I still remember VCP was tested on it. Though this document is good to refer to, there are other components such as NSX, vRealize Operations, etc. that have a certain maximum that we would search high and low for it. VMware has released a site that contains all these maximums information. Though this is not complete, this will be the single source of truth when you find that documentation might not be updated. Not only do you get to see the maximum, but you can also even compare previous versions limits. It is very easy to use, Just 1) Choose a product, 2) Select the version, 3) What type of maximum, you can choose more than one, 4) To display the limits. Now head over to try it out.

I am very new to vCloud Director and in such have a hard time learning how to install this.  I have to rely on reading the installation guide but this cannot beat anything that have been written by someone who have gone through the installation and listed down some of the requirements.  This was all done in my home lab in such, the FQDN here may not apply for production case. I am no linux nor oracle expert so I am going to stick most of my work on Windows wherever possible.  As vCD has released to 1.5 that comes with SQL support, I am lucky that I can drop oracle completely.  As for the requirement for linux, I have used RHEL 5.5. Do not that RHEL is supported for 5.4, 5.5 and 5.6 also know as RHEL 5 update 4 to update 6. Here are some of the reference I used to get my vCloud Director working.
