5 Linux-based Virtualization Companies to Watch on Ken Hess’s Linux Blog is a post about the 5 main server virtualization platforms based on Linux. Ken also mentions the only non Linux based hypervisor, Microsoft’s Hyper-V.

“There’s only one company that doesn’t use Linux for its server virtualization platform. Can you guess which one it is? If you guessed Microsoft, you’re correct. Microsoft is a newbie in the virtualization space but wants in and may make significant dents in the already well-established market that is significantly owned by VMware. For Windows-only virtualization, there may be some validity to the switch to Hyper-V.

For the rest of us, who are either too stubborn or too smart to make the shift to Hyper-V, what are our choices? The following is a list of 5 of the main players in Linux-based virtualization.”

Use the link above to read all of Ken’s original post for some brief info about each platform, but I am listing the 6 products and the links to their free versions for quick reference here. Ken does not discuss nor am I including free hosted platforms such as Microsoft Virtual PC or VMware Server. Read the rest of this entry »

If you run the free VMware Server on a Linux host then VMTN Communities user phxrider has created a couple of scripts that can make your life a little easier. Phxrider’s clone and rename scripts automate the process of two administrative tasks that are frankly a burden to do manually. Both VMware Server 1.x or 2.0 do not offer any template or cloning abilities from their respective GUI interfaces, so these scripts are an essential tool to have if you want to duplicate VMs or change the VM’s files to match a renamed directory.

Check out either http://communities.vmware.com/docs/DOC-8050 or the VMTN Forum thread at http://communities.vmware.com/thread/168266 to download the scripts. Here’s some brief info from these links:

“The clone script does a straight clone of a VM. It copies the directory, renames the files and tweaks all the text inside the files by using sed to replace the old name with the new one, then sets all the permissions to what they would be if you created a new VM.

The rename script basically does all but copy it. This is handy for if you tried to rename a directory manually or attempted a manual copy and then found it still shows up under the old name in the web console. Remember this one assumes you have already renamed the directory to the new name and it MUST be the same as what you intend for the new name to be.

Both work the same way… scriptname <old name> <new name>”

I am not aware of equivalent scripts for VMware Server hosted on Windows, but if they exist please leave a comment with a link for VM /ETC readers.

The rest of this post is my example of using the clone_vm.sh script to make a template for future VMware Server 2.0 VM cloning. Read the rest of this entry »

So everybody and their mother has a virtualization product now. Too bad all the vendors could not standardize on the same key (or key combinations) that releases the mouse from a virtual machine’s (VM) console window. Until that day happens (don’t hold your breath) this post will be my listing of known host key or key combinations by vendor and product for when your mouse is stuck in a VM.

Please leave a comment on any products I have not included and I’ll update the list.

Updated 10.03.08 – corrected key combination for Mac versions and created separate rows for VMware Fusion and Parallels Workstation

One of the posts I used as a research reference was Common Virtualization Keyboard Shortcuts from x86virtualization.com. Check out this post for a complete listing all keyboard shortcuts for Microsoft and VMware products besides the one for escaping the mouse from the VM console.

This session was my last VMworld 2008 session on Tuesday 9.17. I must have missed it in my notebook Tuesday night, so I am posting my notes now. The session was hosted by Mike DePetrillo, Principal Systems Engineer at VMware. Mike did the entire session on one leg. If you saw one of Mike’s sessions or you know Mike you’ll understand that comment.

This session was designed for companies that are primarily Linux shops and have numerous virtual machines (VMs) on VMware virtual infrastructure. Mike provided general information about Linux as a guest OS as well as some best practices and performance tips for both the VMs and the ESX hosts. The rest of this post is my notes from the session.

Mike started out by talking about general recommendations for building Linux VMs.

I had to miss my 9:30 am scheduled session because I was delayed finishing up the General Session post. Luckily VMworld has different sessions on the top and bottom of each hour this year. I think the staggered availability of sessions is a great idea, and it was perfect for my scenario this morning. I am actually more interested in VMware’s Linux strategy anyways. My power is low on my notebook, so this may start as a live blog but my battery might not make it.

Once again the legal disclaimer about forward technologies, but the presenter tells us he can’t give dates … hmmm.

VMware’s Linux strategy is focused along 2 vectors:

• Ensure it is the best platform for linux workloads
• Ensure customers have a wide variety of platform choices to deploy VMware

Here’s the Linux Initiatives at VMware Read the rest of this entry »

I am getting ready for the VMworld 2008 Day 2 General Session and sitting at the official bloggers table this morning. Thanks to John Troyer and the team over at VMTN and Planet v12n for getting this set up. We even have a solid wi fi connection so live blogging looks promising. Look for updates to this post every 15 minutes or so.

Lights are down and the opening video is rolling. Today promises to be more about the new technical features.

Stephen Herrod, CTO of VMware, takes the stage and has started the session. Stephen confirms that his presentation will be about the technology behind the VDC-OS.

He is starting by going through the 3 infrastructure layers. Read the rest of this entry »

I will not be attempting to live blog the entire Q&A session, but when I find a question and reply interesting I will make a note here. The wireless is still spotty, so once again I will keep updating this post as much as possible. I am paraphrasing the answers unless I provide quotes around the statement.
