It looks like what's new is the graphical interface.
These days, most X-Series servers are configured with a very
that acts as the "management console" and organizes the other VMs.
it easier to deploy "appliance" versions of popular configurations and
quickly within server farms. IBM has been working with VMWare for
and is now also supporting Xen.
Different flavors of the same concepts.
In the X-Series environments it's possible to mix and match Linux and
Windows servers within a blade array, or even within the same server
Desktop Virtualization has been rapidly gaining popularity, and it's
quite likely that similar types of technology will be used by Lennovo,
Dell, HP, and Toshiba, possibly within the next 2-3 months. This is
one of the reasons Microsoft has been scrambling to cut deals with the
Linux is very good at "playing nice" with Windows, especially Windwos
2000 and Windows XP. It's very easy to take a PC with 1-2 gigabytes
and install both Linux and Windows running concurrently. You can put
the Windows console interface on one of the virtual desktops, and flip
between them easier than flipping between two computers sitting on the
Because Linux can be told how big a VM can/should be, the OS can
quickly grant that much memory. Running VMs under Windows, especially
Windows XP or Vista is a big problem because the OS fights to keep all
of the memory for Windows. This makes the VMs MUCH slower. Microsoft
could fix this if they wanted to, but they were trying so hard to keep
Linux OFF the desktop, that Linux is now the preferred platform for
the HOST operating system instead of the GUEST.
The good news is that the Windows VM runs better under Linux than it
does on native hardware. Linux manages disk more efficiently, and
this is really important when Windows is going out to the hard drive
alot. I have a Windows VM on my Linux PC and it really runs great.
I've been using VMWare, but if IBM can come up with a really good
graphical interface to Xen that makes Xen as easy to use as VMWare,
I'll probably want to generate a Xen appliance too. VMWare and Xen
are working together to try and standardize some of the key components
Microsoft started out trying to bully the VM vendors into giving
Microsoft control of the system as the primary OS, much as they did
with their other Virtualization offering. The VM vendors refused to
cave in completely, but the Microsoft interface to the VM does contain
patented software for interfacing to the Windows Operating System.
I'm not sure how "original" the patent are, one of the problems of not
being required to disclose all of the code when applying for a patent.
Microsoft also seems intent on preventing retail purchasers from
installing Linux and putting Vista on as a VM Client. It would seem
like this is yet another direct violation of the terms of the DOJ
settlement, but then again, Microsoft and law-breaking or judgement
defiance has become so tightly coupled they are almost synonymous.
I wonder how Microsoft would feel if the Linux community organized
massive attacks against Windows users, infesting their computers with
viruses that did serious damage and disabled their computers? The big
difference is that if IBM did that, Microsoft would be filing lawsuits
and demanding $billions in damages, or hiring some 3rd rate bit player
company to do it for them (SCO). When Microsoft gets caught red-
handed, the DOJ just says "Yeah, what's the problem". A bit like the
Red Neck sheriff who won't arrest the rich white boy who raped all
three of the Mexican fathers virgin daughters. Instead, the sheriff
takes their green cards or social security cards, puts the whole
family in Jail, and has INS deport them as illegal immigrants.
Not much difference here. Microsoft locks out at least 6 Linux
distributions, multimedia players, antivirus vendors, and search
engines, and the DOJ says "what's the problem", maybe we should ban
OSS software and all non-microsoft software so that you terrorists
won't be able to attack the system.
