VMware Hypervisor Static IP

leave a comment »

One of the few frustrating experiences learning VMware Hypervisor has been loosing my server!  At install time, I must have defaulted to automatically getting an IP Address from DHCP.  Twice now, I’ve attempted to login thru vSphere and my server is nowhere to be found.  The hosted VMs are all accessible.  Its just VMware that goes M.I.A leading me to the suspicion that I did something wrong.

My usual fix is to scan my network for devices.

After figuring out which IP Address is my server at now, I proceeded to the servers configuration page on the right and selected networking from the mid-left pane.

Image

Selecting properties from the rightmost panel brings up the networking details for the server.  Here, I can see my new IP Address as well.

Image

Selecting Management Network from the left pane and pressing the edit button brings up the network properties where I can change the IP Address.

Image

Easy enough, I changed my settings to statically set my IP Address.  Done!

Cloning/Backing up a VM in VMware vSphere Hypervisor

leave a comment »

One missing feature of the wonderful free version of VMware vSphere Hypervisor is the auto-magic way of cloning a VM.  Nothing I could find at least on this.  There are features for managing snapshots of VMs, for taking snapshots and related tasks, however, to backup/clone a VM, you have to take matters into your own hands. 

Before you follow this steps, ensure the VM you’re about to clone is off.

First step, on your VMWare GUI, from Storage section, right click/browse the datastore where your VM image is stored.

On the Datastore Browser, create a new folder.  This directory will shortly become your cloned VM directory.

Image(17)

Having created a directory for the VM (to be cloned), click on the folder of the VM you want to clone now.  From the contents of this directory, select all the files, skip the logs and right-click copy.  Notice screen-grab shows .ldk and .vswp files.  The existence of these is because I grabbed the image from a running VM.  Remember the VM to be cloned should be shutdown.  These files should not be part of copy/paste steps.

Image(18)

Having copied all the files, go back to the newly created directory and right-click paste these previously copied items.

Image(19)

From all the copied files, right-click the file with the vmx extension and select ‘Add to Inventory’.

Image(20)

Select a name for your newly created VM

Image(21)

Finally, select the location of new VM.  Here you can see me place all ‘Base’ VMs in their own ‘Resource Pool’.  I am only doing this to group together copies I make of any VM I configure.  I haven’t even looked up why I want to use a resource pool for its intended purpose.

You’re done!

As mentioned at the beginning of this post, there may be an official way of creating/cloning VMs in VMware vSphere Hypervisor but I do not yet know how.  This, however, works like a charm, enjoy.  Thanks for reading.

leave a comment »

Last night’s meeting was a cozy but a good one.

Will Gorman from Pentaho graciously presented on Pentaho’s OLAP Solution (Mondrian) and I presented on MicroStrategy’s equivalent (Intelligent Cubes).

Another worthy note is that we had a announcements for job postings…

Companies present at meet (and recruiters) were looking for one of each:
- Informatica Developer
- MicroStrategy Developer
- Senior BI Developer
- Junior QA/Java Developer

It seems to be a great time to be working in IT in good O-Town. If you want to find out about our next meetings, jpb opportunities and networking, check us out at our CFBI Page and become a member.

2.0 GB Macbook Ram (new)

leave a comment »

I have no use for the original ram (2.0 GB DDR3) that came in MacBook Pro and it is not worth putting up on Ebay.

If the new one I just put in doesn’t blow up and you’re interested, send me an email first and we’ll figure out a way for you to get it free…

Cheap and functional tea steeper

leave a comment »

A nice perk of working in ‘Downtown’ Winter Park is the variety of little shops close by. Nice for walking. I recently visited Spice and Tea a few blocks from Caxiam. I didn’t know we had a tea shop (and more) so close… neat.

Anyways, figured I would mention, I found a very nice tea steeper for the office.

I had never seen one of these before and I am pleased to mention that it works great… definitely better than a tea ball! It is very easy to wash and collapses neatly for storing. It would be nice if it had its own little tray or something but, hey, its cheap and does plenty. :) Green is the best color.

Upgrading your Mac?

leave a comment »

… oh so brief a message. One sentence only!

If you’re thinking about upgrading to a newer Mac and go the refurbished route (I do); buying new from Amazon saves you tax making retail that much more attractive so you may be able to move to a newer lappy with long lasting battery, etc. for the same money (after adding tax) as you would have spent at Apple.

Mingle Lessons Week Two

with one comment

A week and a half into our current project… here’s are my lessons and miss-steps so far. I am certain there are more to come.

  • Originally scheduling 8 hours per developer per day. I should have known better but this one slipped big time. Perhaps I was too enthusiastic about estimating how many tasks we could do. I’ve been re-examining this for the past four days and believe 6 hours (top) per developer per day is realistic.
  • Assuming developers would be allowed to work on project full time. Ha! Sometimes we put up to half our time into project and half into various side tasks that need to be done as well. For other developers, this is much worse; they may have no more than a few hours a day to work on this project. This one is tricky since we cannot choose not to do tasks that need to be done.
  • Ramping up our project has been a bit slower than I expected. I blame myself for this one 100%. This is the first time I work in a project with this established team and this has forced everyone to adjust to each other (yeah because of me :( ). I am fortunate that everyone is very open minded and, at least, entertains my thoughts even if they are way off the current pace.

    Still, this is the most exiting lesson so far. We can sense increasing speed going thru tasks and handling those things we hadn’t thought of. It feels great to be developing a rhythm with my teammates.

  • Clearly, all these lessons are not related to Mingle but to web projects and the management of these… This makes them that much more important to me. I am certain that, taking these into consideration, will greatly improve our development workflow and pace.

    Mingle Project Overviews

    leave a comment »

    A week has passed since our first project using Mingle started at Caxiam. Even thou this was a short week, we have been able to ‘eyeball’ a roadmap out of a mountain of things to do on this project. Provided the team can work seamlessly and each member focuses on his tasks, Mingle will be a great guide as work gets more complicated.

    So far, my favorite feature in Mingle is the ability to set any particular report or ‘view’ as a standard page. This is a bit more than a fancy aggregated report. Any user is able to view current workload broken by resources, priority, iteration, really, any metric shared among all existing tasks.
    It is invaluable to be able to reassign a particular task to a different iteration or assign it to a different developer. All the metrics for a view are then recalculated to provide a quick overview of your actions. Shuffling tasks between iterations recalculates the sum of the hours of work per iteration or reassigning tasks to a different developer recalculates each developer’s workload accordingly. It sure beats weekly re-prioritization meetings.

    A picture would be invaluable to illustrate this point but content of these things is sensitive to both our company and our clients so the best I can do is point to whatever information Thoughtworks has available…

    Project overview

    The illustration above depicts a typical project under Mingle broken down per status (let’s imagine). Imagine a series of aggregates on these different statuses for time allocated, time elapsed, etc. Moving (heavy use of AJAX) cards (boxes) from one status to another automatically recalculates relevant affected metrics.

    This is but one of many features on Mingle. I would say that early in a project, this is one of the most useful ones. The ability to quickly task a team, and reshuffle quickly as things happen is priceless.

    It is worth mentioning that shuffling 20, 30 cards at a time puts these requests in a long queue where one can only sit back and wait until all one’s actions are realize. I think this could be a deal breaker in a big project with a thousand tasks perhaps… My experience here is very limited, perhaps our Mingle server needs more memory.

    Lastly, a lot of the benefits provided by Mingle are greatly diminished if not everyone on the team uses it or runs a parallel number of tasks outside of Mingle. This effectively puts a dent on everyone else’s work. It is most important that each developer updates his tasks and sticks to their queue… it is rather easy for any developer to ‘grab’ more tasks unassigned and stay busy so this should not happen.

    One thing I have barely touched here is how a project is broken into little bits in Mingle. The basic idea is to break down everything into a series of ‘card’. Perhaps that will be my next post.
