Important Notice: This post has been updated using a newer, easier method. Read more here.

I’ve had a really hard time trying to find the way to get VMware Tools on Linux virtual machines, but I’ve got it down to just a few steps. If you’re using a ‘big name’ distribution with a graphical interface, it’s not hard to install. But, I like to use Debian or Ubuntu, without X11 (the aforementioned “graphical interface”), so it’s a pain in the butt.

How to install Vmware Tools on Ubuntu without X11:

  1. Install Ubuntu Server
  2. Login
  3. Create a root shell:sudo bash
  4. Update your sources:apt-get update
  5. Upgrade your installed packages (dist-upgrade to force kernel upgrade):apt-get dist-upgrade
  6. Reboot
  7. Create a root shell again:sudo bash
  8. Install packages VMware Tools needs:apt-get install linux-headers-server build-essential
  9. Install VMware tools
  10. Mount the VMware Tools CD ISO:mount /cdrom
  11. Copy VMware Tools to home:cp /cdrom/VmwareTools-x.x.x-xxxxx.tar.gz ~
  12. Go home:cd ~
  13. Untar/Gzip the install:tar -zxf VmwareTools-x.x.x-xxxxx.tar.gz
  14. Go into the resulting directory:cd vmware-tools-distrib
  15. Start the installer:./vmware-install.pl
  16. Install will ask you questions, the defaults should work fine.
  17. Remove the basic AMD PCnet module (if you get errors about building the ethernet driver, run this command and start at step 14 again):rmmod pcnet32
  18. Rebuild module dependancies:depmod -a
  19. Install the VMware accelerated network interface:modprobe vmxnet
  20. Restart network service:/etc/init.d/networking restart
  21. Reboot

I wish I had been told about the caveats of importing your old VMware Workstation or Server virtual machines into ESX. VMware always talks about how portable their virtual machines are. They aren’t lying, but once you switch to ESX, it’s not nearly as easy as it is with all of their other products.

I had a few Ubuntu or Debian virtual machines that I had been running on VMware Server. I also tried to copy my Windows XP virtual machine template to the ESX host. No dice. But why?

VMware ESX does not support virtual machine disk files that are IDE. You may only use SCSI disk files with ESX.

There’s not even an official migration or conversion path from IDE to SCSI, or even a reasonable unsupported one.

I wish that fact would have been posted somewhere. I’ve been using VMware Workstation for a long time now and I’ve never read about the IDE disk problem with ESX.

Now I did have a SCSI disk based virtual machine, and it imported pretty easily.

Update: I found two sites to try. I’ll update again if they actually work.

Fingers crossed.

My boss and I have been thinking the same thing apparently. Last week our ‘big server project’ was implemented and now we have to live with it. We installed a 2 server VMware Infrastucture 3 cluster complete with SAN. The real deal. I have a feeling it is just the start of much more. I’m very, very excited about it all. (Can you tell?)

It’s a big move for us, previous to this we had 8 independent servers, and a NAS (basically a normal server with more drives than the other ones). It wasn’t bad, but it was very inflexible. Now, we can be nimble.

Today my boss and I were looking at VMware training. It only seems natural to get more training on what you’ve gone head first into. We had confidence in the vendor we chose to implement the project, and I think we chose well. So far it has been as smooth as I expected. Now we have to take over the torch, it’s our baby now.

With training generally comes certification. I’m very interested in becoming a VCP after taking the official training sessions. Not for some professional reason, or to make me more ‘marketable.’ I just feel like it’s a topic I’m passionate about, and it would be nice to be able to prove “hey, this guy might just know a thing or two.”

So I’m thinking, sure, I get the knowledge. But then what? At some point I’m going to have our infrastructure needing very low maintenance. There’s going to be a limit of what I can implement in-house.

After having been to a handful of IT and education gatherings, seminars, or conferences, I really have a feeling that my school is just way ahead of others in many ways. Now, I’m only talking at a technology implementation level here. I’ve gotten some dropped jaws describing our previous desktop deployment method to other people in a similar position to mine or my boss. Things we’ve deployed like networking, desktop and application deployment, virtual servers, and wireless are way beyond what some districts have even dabbled with. We’ve been blessed with a large amount of community support and administrators understand the importance of technology. I think the progress we’ve made really illustrates that fact.

Today I made a comment about ’selling’ our service to other districts. I was joking somewhat, but it would be interesting to not be a money pit like the average school district department. A revenue stream in a school district? Who knows. My boss made a comment like it was something she had put some thought into already. We’re both very proud of everything we’ve accomplished so far and even if don’t sell our services and knowledge, we want to show off our stuff. We want to help other school districts, exchange knowledge, and as I said before, perhaps even sell our services.

There lies a problem, she explained. How much support do you give? Where does it end? How much time spent is too much? She thinks it will most likely interfere with the business we need to get done ‘at home’. I don’t disagree, but I think it might be worth it in some way.

It’s a short term goal of mine to offer a session at the eTech Ohio Educational Technology Conference. The whole event is 3 days of seminars/panels/displays from other districts, educators, or vendors. There’s a large exhibition hall where you can see all kinds of products. I was pretty disappointed at the selection last year. It had a lot of vendors, but nothing I actually thought was cool. Cisco was demonstrating products we’ve been using for 2 years already, and didn’t know about products we would actually want. There was a session that focused somewhat on VMware, but only 5 people showed up. 3 of those people were myself, boss, and a coworker.

I think I want to somehow demonstrate how we do things on the IT side of things. How we do it, why we do it that way, and what mistakes we’ve made along the way. I’d like to include desktop and software deployment, virtualization, and web-based software we use. I could also like to describe our next steps into other areas we’re dabbling in, like content and document management.

Shannon was just telling me about some bad customer service she has to put up with at work. It seems that:

  1. Her mouse doesn’t work, which causes mistakes.
  2. It takes 3 reboots to properly login, making her ‘late’ in the morning.

To me, these things are unacceptable. The “IT” staff have replaced the mouse a few times. These issues would never fly if I knew one of my customers (teachers) had these sorts of problems.

What’s worse? She’s complained to her boss about it any got yelled at with “there’s nothing I can do about it!” Awful. Stick up for your people, man.

Query: What kind of IT support do you receive at work?

I never thought I would be ‘blogging’ but here I am. I’m not sure what direction the content on this site will go, but I suppose nobody does initially. I hope to update it often with little tidbits instead of monster posts. Feel free to subscribe to it using the Entries RSS feed.

My idea is to combine the topics of Computing (What’s cool, What’s new), Information Technology (Stories from the life of a network admin), and Instructional Technology (Supporting teachers using technology in the classroom and helping our students get ahead)

If you want to know more about who I am, and what it is I actually do, check out the “About” link at the top.
