VMWare Integrated Openstack issues

Standing up the environment with the integrated Database is easy enough however if you want to add Active Directory into the mix it gets more fun.
During this I encountered the following issues:

  1. No way to change without blowing away the deployment and re-deploying.
  2. Error messages were often misleading.
  3. AD Structure very Important
  4. Forward Slashes in AD “cn” are BAD!!
  5. Users without a UPN cause issues.

Compile Raspberry Pi Kernel

update: 2015-02-10: Removed folder sync as was causing builds to fail

Decided to play about with the Raspberry Pi Kernel but setting up the toolchain for a cross compile was a bit of pain not to mention remembering to download everything.
So I put together a Vagrantfile that should auto do it.

Following Variables can be edited at the top of the Vagrantfile:

Deploy Centos 6 from VMWare Template

This is just a quick gotcha that I found ages ago then forgot about and then had to figure out again. Before you convert the VM to a template.

rm /etc/udev/rules.d/70-persistent-net.rules

sed -i ‘/HWADDR*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

sed -i ‘/UUID*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

 

Update:

This also applies to SLES 11 SP2 (use /etc/sysconfig/network/ifcfg-eth0)

 

 

Good News and Bad!

Bad news is that as of the 2011-12-31 I finished working for my Employer in order to move back to my home country, so I no longer have direct access to (and responsibility for) VMWare (and all the other really cool stuff we had, infini-band, HPC etc.) To top it off I was told before I left they intended to implement vblock (I suspect they just wanted to make me jealous ;) )

Good news is that from the 2012-01-09 I am starting my new job which will be mainly SCCM to start but moving into Citrix as well. So you will likely see no more VMWare posts, however I intend to make it up to you all by posting lots more

Clone-VMFromSnapshot

This is a function that allows you to clone a VM from a specified snapshot. The only way to do this in the UI would be to take a snapshot of the current state, revert to the one you wish to clone, clone, revert to latest snapshot and then delete latest snapshot. As you can see that is time consuming and takes numerous mouse clicks.

I recommend adding this function to your powershell profile so you always have access to it.

As always feel free to comment.

Update Custom Attributes for VMhosts in vCenter

Yet another role added to my Job description, Now I am managing our Virtual Servers. So true to form I’ve dived headfirst into powershell / powercli to see what I can do. Some of the posts coming up on this will likely be similar to others around the web as I reinvent the wheel while I learn. But you never know one of you might find me 1st or I might do it in a way that suits you better.

First up is a simple script to read data from an xml file and then update custom attributes on the vmhosts.
