I will limit my question to two products then, namely Xensource's and
VMWare's products.
Anyone ?

Hi Johan,
XenExpress, XenServer, and XenEnterprise are all products of
XenSource, not RedHat.
They are all "added value" that XenSource adds to Xen.
RedHat starts with Xen and add's their own "added value". Their
limitation of 4 concurrent VM's is a support limitation. Basically
their way of saying "If you do this, and it breaks, don't come runing
to us."
BUT ... there is a hardware limitation that I've been seeing.
Basically if I try to run too many virtual machines on a machine
without enough memory, at some point I get a "Hay ... you don't have
enough memory to squeeze in another virtual machine" message. It
doesn't really say that, but that is what it means.
So back to your questions. I'm not going to answer them, but I am
going to point out that you really are asking to compare 3 different
products, not two.
You want to see the comparison between XenSource's products, VMWare's
products, and RedHat's Virtual Products.

I've posted previously about Xen. But know I have some more specific
questions.
In RHEL5 Xen is limited to 4 concurrent VMs, which could mean that
RHEL5 ships with Xen Express (the free starter package). In one of
the replies on my previous post it was mentioned that there were no
such restrictions on the number of concurrent VMs in SL5. Can someone
give an explanation for the difference in concurrent VMs for Xen in
SL5 versus RHEL5 ?
Without having to rtfm, what is Xen 3.0 in comparison to XenExpress
(free version), XenServer (only Windows) and XenEnterprise (windows
and linux) ? Is Xen 3.0 the basis on which the other 3 are build and
then you just pay for the comfort of someone else having done it for
you, some management tools and the support ?
Can someone compare Xen (free & commercial) with VMware
Infrastructure (starter to enterprise) ? When to use what ?
Difference in features. Because VMWare Infrastructure , especially
the enterprise, has a serious price tag.
We would use virtualization for webservers, files and mysql-database
servers, grid-computing, ease of setting up test and development
servers.
thanx,
Johan
