vSphere Web Client: Organising your VMs

It is common for large customers with multiple clusters to use Resource Pool to organise their VMs. The reason is the VM folder spans across clusters. The folder is at the datacenter level. The screenshot below (vCenter 5.5) shows the folder. I use folders a lot. A limitation here is I cannot filter them by cluster. The Datacenter actually has 2 clusters. That’s not visible here.

vSphere web client makes it a little easier. It still does not have the folder structure. This means I cannot see a folder hierarchy (parent folder, child folder). However, I can now show my VM by cluster. In addition, I can filter the list, as can be seen on the right.

As a bonus, you see that under “Related Objects”, there are objects beyond VM. This means I can list other objects. For example, I can choose datastore. The filter on the right changes accordingly.

I think the Filter features are very useful in large environment. Cool!

Migrating your WordPress blog to GoDaddy – part 1

[e1: Updated on 23 Feb 2015. I had to repeat the entire process! The Nameserver was pointing to the old hosting provider]

I had to migrate my blog from the current provider it went down several times. I chose GoDaddy as my domain is also registered with them. Because my blog is based on WordPress, I chose the WordPress package. GoDaddy provides a migration tool, which makes the process much easier. There are still things to prepare.

GoDaddy will need an FTP site, user and password. The problem is the Path value. As you can see from the screenshot below, the value has to be Undefined. That actually means the “root” directory. I did not know that, and GoDaddy Support did not provide advice that it had to be at the top directory. I had to create a new ID, as the existing ID has a password that I do not know. In the directory field, type “/”, and this would set it to root directory. [23 Feb update: I could have modified the password of the existing ID. There is no need to create a new ID]

0 site migration

You also need to know your WordPress admin. The screenshot below shows that.

0 site migration 1

Once you did the above, you are ready to migrate. You click the Migrate choice.

1 site migration

It will take you to the screenshot below, where you fill it with the info that you’ve prepared earlier. Notice that GoDaddy provides you with a temporary host name, which is great.

2 site migration

Clicking the submit button will get you the screenshot below.

3 site migration

If you check with the All Hosting Accounts page, it will show you that your site is being updated.

4 site migration

You then get the status below. If your site is pretty small, this is done within the 30 minutes.

5 site migration

You can actually check what it looks like. This is what it looks like before it’s updated

6 site migration

And… after it’s updated! So it’s basically all copied! Thank you GoDaddy!

7 site migration

Now, because of the temporary address, I need to migrate the hostname too. This is not easily shown in the migration wizard. If you do not do this step, the domain is not associated with the migrated content. Click the “Add Domain” button.

8 site migration

Since my domain is with GoDaddy, I can easily just choose from a drop down.

9 site migration

Once you submit, you can see that the status is now reflected, as you can see below:

9 site migration - 1

I gave it around 1-2 hours, and it’s done!

9 site migration - 2

This is much easier and a lot less scary than what I thought 🙂

23 Feb 2015 update

…. and that was the beginning of my nightmare. Little did I know that the DNS is still pointing to This is because the Name Servers are not modified by GoDaddy migration tool. The tool does not inform that you need to do it. Please read this for details.

Why a 40 minute presentation takes 4 days to prepare

As a VMware SE, I present a lot. It can be public speaking in events, or present to a small group. Certainly, all of us who have been doing VMmare for a long time can just stand up and present, especially if it’s a technical topic. After all, the content is all in the brain.

However, I learned that the difference between a great presentation and a good presentation is much larger than what I thought. Much larger than the different between a good presentation and an average presentation.

A great presentation has that lasting impact. It goes beyond educating. It changes paradigm. They also remember the key message long after they forget the content. It gets put deep in their heart. Another word, you’ve calibrated their thinking with yours.

So what makes a great presentation?

A great presentation… looks natural (as if you speak from your heart, not your brain)…, is both humble and authoritative…., is both funny and deep…., is both engaging and relaxing….., is both entertaining and enlightening…, and truly leaves a moment of truth.

I find that delivering a great presentation is very hard. I normally take around 40 hours to prepare 40 minutes presentation. The less technical the topic, the longer it takes. The less technical the audience, the longer it takes. The less interaction I have (e.g. due to large size), the longer it takes.

I created all the slides manually, I typed every word I want to say in the speaker notes section of Power Point, Then I rehearsed, rehearsed and rehearsed. I time myself if time is a constraint. For an important event, you are right to guess, pretty much the whole thing is memorised from so much of darn rehearsal! 🙂

So anytime you see me speak naturally, it was more like virtually natural 🙂

To me, a great presentation is like an entertainment. How long does a singer practice and rehearse for that 4 minute song?

Here is an article that I find useful.

All the best in your presentation!
