I can’t believe people are writing stuff like this. VMware has a product that’s better in VMware Server and it’s free too!
Read this http://www.infoworld.com/article/07/12/ … iew_1.html and see that you should really be using VMware server which is free and better than HyperV!
notes came from here:

Hi,
i managed to get my ESX3.5 to boot and run on a HP ML 115.
onboard raid: yes, this “raid” really sucks, because my rescue cd found 2 controllers/disks -> NO RAID
TODO-List to get ESX-3.5 up and running.
1.) install it from the cd (of course)
2.) reboot with a linux live cd of your choice.
and now i hope that there are no typos…because i created this “script” on my laptop during i tried and tested it on my ESX box!

This is a total load of FUD. Like most of the comments here, I must agree. Even WHEN this so-called HyperV does come out, it still will lack the features that VMware currently HAS! If you’re already running VMware, why would you DOWNGRADE!? If you’re not, why would you adopt an UNPROVEN LOSER 1.0 release!? Just like a lot of people are upgrading from Vista to XP, people will be upgrading from HyperV to VI3, which will be 2 years OLD by the time HyperV comes out. VMware stays atop for at least 5 years as nobody comes close just yet.
Here’s the story:

In the guest, you’ll want to run NTP and not use the VMware tools time sync. It seems to work better. Also, you might also considering Ubuntu 7.1.0 instead as with ESX 3.5, VMware Server 2.0, and Workstation 6.0, it has a VMI option, so that you can run a paravirtualized kernel and get up to 30% better performance. It also doesn’t have the LSILogic scsi driver bug that everyone seems to run into.
If anyone didn’t know, you should know now. I used to just think like … if it worked, why change. Well, there were a lot of videos that I couldn’t watch before and with VLC player, I could! It must be certain bits that are missing or something from the files Windows Media Player wouldn’t play it. VLC will!
You can get VLC Media Player for free here:

NEW YORK (AP) — A Jefferies & Co. analyst downgraded Red Hat Inc., saying competing technologies are nabbing market share and could hurt profit growth, as the software maker deals with rivalry by making acquisitions.
Katherine Egbert in a client note cut her rating on Red Hat to “Hold” from “Buy” and reduced her target price to $19 from $23.
Red Hat will have to work to diversify its business away from its Red Hat Enterprise Linux products, which are based on open-source software, Egbert said. That’s because newer virtualization technologies, which allow businesses to use different computer operating systems on a single server, are replacing Linux servers as companies work to cut costs, Egbert wrote.
Often new servers are shipped with a key competing product from VMware Inc., which is cutting into Linux market share, she added.
But Red Hat is diversifying through acquisitions and could step up this process, Egbert said, which could eat into earnings potential.
This is total bullshit for lack of a better term. What in the hell does VMware have to do with Red Hat? They are new and coming into the Virtualization space! VMware actually allows OS vendors to sell more licenses!
Let’s see here “virtualization technologies, which allow businesses to use different computer operating systems on a single server, are replacing Linux servers as companies work to cut costs” … what the fuck!? So you’re running different operating systems … what operating systems might they be? Windows (costs money), more Linux? Probably! They’ll be running other operating systems … just less computers!
Anyone else with any input on this?[ad#ad-1]
