Xen users - Feb 2007 - Any largeish deployments of Xen? References?

Hi.

I''ve been using Xen for about two years now and I''m a very
happy user.
For the last year we''ve been using Xen in production environments and
it''s been performing well. We''ve now started pushing Xen for
projects
involving 10-20 servers but we are facing a bit of resistance. It
reminds me of pushing Linux in Unix environments a few years back. :-) A
customer of ours is quite skeptical and he wonders if there are any
other users out there with large installations of Xen? If someone could
send me an email and be willing to say to this guy "Yes, we''re
using Xen
in an Enterprise enviroment and its been performing good" I would be
eternally grateful.

TIA

Per.

Oracle Austin Data Center. Although you''ll have to contact them
directly
to get the verification goodness that you are looking for....

BTW, your customers are right to be cautious about "data center
readiness"
of Xen in immediate time frames. The software is still a baking cake,
and
the community is still becoming a community.

Could you elaborate on that? Would this be due to
 * lack of stability?
 * lack of tools?
 * lack of commercial support?
 * lack of application support?

Agreed. XEN isn''t ready for stable production. If you''ve to
care about
high availiability or guaranteed uptimes XEN shouldn''t be you tool.

Statements like this aren''t particularly productive.

I''ve been running PV Xen in production for almost 2 years with no
problems
for a small set of high load systems.

Xen itself is probably not easily manageable for a large install.  Something
like Virtual Iron which is Xen-based and has a very nice look node PXE boot
management system with HVM live migration might be better right now.

But Xen certainly works well enough for PV based linux server production
work.

If fact there was just some messages on the devel list with some guy talking
about 5 9s with Xen.
