VMworld 2013 Session Voting Open

Ladies and gentlemen, the VMworld 2013 Session Voting has begun!  I have submitted a couple of sessions both by myself and with some fellow colleagues.  You will need a VMworld ID in order to vote.

Bilal Hashmi (cloud-buddy.com) and I will be presenting Session ID 4873, vCenter: The Unsung Hero, where we will dive into the importance of the availability of vCenter and how it affects the services around it that tie into it.  We will touch on some best practices and other solutions to aid in building a resilient vCenter.

Dan Mitchell (vCO Sr. Product Manager) and I will be presenting Session ID 5703, Supercharging vSphere Web Client with vCenter Orchestrator (vCO), where we will dive into how to extend the functionality of the vSphere Web Client with the awesome-sauce of vCO.

Lastly, I will also be presenting Session ID 4875, vCenter Orchestrator: A Beginner’s Guide, where I will embark on the journey of what vCO is and how you can use it to extend your cloud automation and orchestration.  I will be taking the stance of presenting in a manner that will bring light to anyone who is new to vCO!

Here is a screen of the sessions: VMworld 2013 Sessions

If you are interested and want to learn some cool stuff then go vote for the sessions, it would be greatly appreciated!  You can vote by going to VMworld 2013 Public Voting and clicking on the “Thumbs Up” icon by the session name.  Be sure to filter by either Session ID or my name to get the above list.  There are quite a few awesome sessions this year and hopefully, with your help, I will bring some of that awesomeness to the table!

vCenter Certificate Automation Tool 1.0

So for those of us who have experienced the wonderful times of dealing with replacing or updating certificates within our VMware infrastructures, VMware came to the rescue (kind of) and provided a tool for us to use.  This tool has been dubbed vCenter Certificate Automation Tool.  A little excerpt from the release announcement:

Fresh out of development today VMware has a new tool to help everyone with the implementation of custom certificates. The vCenter Certificate Automation Tool 1.0, will help customers update certificates needed for running vCenter Server and supporting components. 

In order to use the tool, you must have the following:

    Administrative privileges on the server(s) you are running the tool on. Although non-administrator users can download and launch the tool, all operations will fail without the proper permissions.

    • Access to each server that has vSphere components for which the SSL certificate will be updated.
    • All vCenter Server components which will have their certificates updated have already been installed and are running.
    • The new certificates already exist and you know the location of the new certificates. For increased security, generate each certificate and private key on the machine where it will be used. The new SSL certificate for each vSphere component must have a unique base DN.

So you don’t have to go around looking, here is a couple of links to KB articles on how to use the vCenter Certificate Automation Tool:


Just wanted to share this with the readers…enjoy!

Host Disconnects from vCenter in a vCloud Director Environment

So I ran into an issue the other day regarding host disconnects within vCenter in a vCD environment.  SSH’d into the host and noticed right off the bat that vmkernel.log was showing the following error:

WARNING: VisorFSObj: 893: Cannot create file tmp:/current.png5557 for process vmx-mks:Cell Profiler x64 (b9d6aa64-d789-4954-bde9-f2875406c159) because the visorfs inode table is full. 2012-10-05T12:38:49.808Z cpu27:6014573)WARNING: VisorFSObj: 893: Cannot create file /etc/vmware/esx.conf.LOCK for process esxcfg-advcfg because the visorfs inode table is full.

And in hostd.log I saw this:
