Ars Technica reports that multicore processors and virtualisation will see the (physical) server market shrink. (Not actually a reduction in the number of servers, mind you, but a slowing of growth from 61% over 3 years to 39%).

Turns out this could be good for the planet. As Treehugger says, virtualisation is a good way to green your servers by not over-providing for occasional peak processing loads. Makes sense, especially if the stats are right: that most servers only run at a load of 5-12%, but burn hundreds of dollars worth of power every month.

If you’re more at home with mucking about on Virtual Machines, then you might be interested to know that Virtual PC is now free.

Billy Bragg has applauded MySpace for backing down on their T+Cs imposed on artists who used the site to distribute music. “I am very pleased to see that MySpace have changed their terms of agreement from a declaration of their rights into a declaration of our rights as artists, making it clear that, as creators, we retain ownership of our material.”

A couple of weeks ago Josh posted about virtualising your overloaded, slow, not-rebuilt-for-years PC, and keeping it on standby within a new build in case you need anything on it.

How about the idea of keeping that new build clean — putting on only your most frequently used, essential applications, with everything else going onto a virtual PC?

For me, that would mean Office, Firefox, my usual web-building stuff (Photopaint, UltraEdit, Filezilla), Nero, and one or two others, such as perhaps Trillian. I’d draw a line under them, and anything else not worthy of a permanent spot in my Windows setup would be virtualised, possibly in various separate virtual PCs, setup for different roles: one for Visual Studio, one for trying out freebie apps from mags, a Linux setup for LAMP development, one for stupid software that insists on running as Administrator, etc, etc.

What to use for the virtual machines? There’s a few different options.

The freebie Virtual Server will only support Windows NT 4 and above, and only server OS’s, which to my mind would unnecessarily weigh down your virtual machines with more than they need. (Linux as a guest OS seems to be coming.)

Another option is the free VMWare Server, which will host a wider range of guest OSs.

The non-free Virtual PC will host just about any x86 operating system. If you don’t want to try the 45 day free trial, it’ll set you back A$215 or so, or it’s available via MSDN Universal.

A problem would be performance, of course. It’s not like emulating a 2Mhz 6502 under BeebEm. But then, hopefully it’s not as bad as what I’ve seen on my brother-in-law’s PowerPC Mac trying to run x86 AutoCad in Windows 2000.

Nonetheless games and other performance-intensive apps may not perform well under virtualisation, especially if they require particular hardware. And yet they would benefit the most, as they often have installers that wreak havoc on Windows setups, chucking weird-arse DLLs everywhere. As the “Virtual PC Guy” is fond of telling us, a lot of the older games run okay, but newer ones might be a problem.

Maybe the only solution there is to put them on a completely separate computer, or move up to Intel’s latest chips which have better support for virtualisation.

Or give the whole thing up and resign yourself to a slow computer with rebuilds every year or two.

I think I’ll try Win98 with a couple of recent-ish games (say, Midtown Madness 1 and 2) and see how it goes.

• Installing Win98 on Virtual PC in 7 easy steps (with a download for a VPC boot disk — very handy)
• More Virtual PC boot disks
• How to configure Ubuntu Linux for Virtual PC
• Which OSs work in Virtual PC/Virtual Server, and which don’t
• Comparison: Virtual PC vs VMWare Workstation. In summary: They’re both good, depending on precisely what you want to do. VPC is easier to use, but VMWare has more power and slightly better performance. Includes some good performance figures, which show virtualisation isn’t necessarily mind-numbingly slow.

Apple launches Boot Camp, to allow Intel Macs to run Windows. There’s already some screen grabs of it running.

As one commenter said: Wow - this is GREAT! Now I can combine the overpriced hardware with the inferior software!

As Ed Bott points out running Windows through virtualisation would be even better. MS’s Virtual PC doesn’t currently run on Intel Macs, but evidently they’re working on it.

First VMWare made VM Server free.

Now Microsoft have proven they can copy that idea as well as anybody: MS Virtual Server 2005 R2 is now free.

What if Microsoft was marketing the iPod? (Article about the origins of the video here.)

In case you’ve been living in a virtual cave, VMWare’s basic VMServer product is now free.

Found an old quote of mine:
To me, reading Perl is a little like trying to understand Norwegian. A minority of things - essentials like “Help!” or “Hello” - I can probably understand. The rest is just gobbledygook. (Quoted here, originally posted here.)
