[!! SPAM] RE: Virtualization recommendation

[Gilad Ben-Yossef]

Hi,

We developed and support for years now a software product for tech support
centers that uses KVM as a hypervisor.

One installation at Canon in Japan runs 35 concurrent Vista/win2k/xp and
soon Win7 instances.

Each session is about a minute long (it is used by tech support people to
help them guide clients to solve problems over phone/email. Sessions are
accessed by users via VNC in their browser. There are 2000 such sessions a
day.

The start time for a new session with Vista (the heaviest OS) and an
application ona loaded is between 6 to 9 seconds (well, let's say we are
also have some  resposability to this specific ability as upstream KVM
doesn't do that.

The perfomance, stability and flexability are unparalleled. They enabled us
to develop a unique enterprise ready virtualization platform in record time
and a cost which is lower then the license fees of a big installation of
propritery solution for a single year.

Xen and VirtualBox are nice and have their uses, but KVM is amazing.

Care to give more details? Especially compared to Xen?
I googled for "kvm vs. xen" but all the links I found so far talk
about KVM's potential (and are a bit outdated).
A view by someone who actually got their hands on it would be valuable.

We use CentOS almost exclusively, though being able to run the odd
Windows Server 2003 instance might be interesting to support legacy
parts of our system.

Thanks,
