Actually VMware Server 1.0 is free as of about a month ago.
We have it running on a Fedora FC3 box.
Free as in beer perhaps, but not free as in speech.
My goal was to have it install as easily as possible. I
haven't put a whole lot of time into exploring XEN, but so
far it is def a lot harder to configure and since vmware is
free I decided to start with this.
I'm running Xen and adding a new host is as simple as carrying out a few
simple steps:
1. Add 2 new LVMs, one for the root partition and one for the swap.
2. Run mkswap on the new swap LVM
3. Copy over my "template" partition to the new root LVM (I happen to
use dd for this)
4. Create a config file (again, I just copy a template and change a few
lines)
The biggest problems I had with my initial Xen install were:
1. Setting up Xen's bridge interface. My workaround was to disable Xen's
bundled script and just do this work on the host OS itself. If you'd
like, I can send that script to you.
2. Adding support for more than 4GB of RAM to the Xen kernel.
I'd certainly be open to XEN if someone can figure out the
details of the install keeping it very simple. If it is too
difficult to install then it kind of defeats the purpose of
an easy dbmail install. But again I'd love to keep
everything on open software.
IMO, providing what appears to be "ease of use" (a subjective issue at
best btw), does not justify promoting the agendas of companies who
promote freedom-restricting wares like VMware.
I know this is starting to border on off-topic so feel free to contact
me directly if you'd like to continue this thread.
All the best,

So I've been working on a simple way to scale / install
the
DBmail-Postfix system we put together. The idea being
that
it takes just to many steps to configure a complete new
system, thus too long and prone to mistakes in
situations
where we might really need a new box in a matter of
hours
not days.
I've explored a bunch of options including imaging and
current free/open virtualization solutions.
I selected VMware's free virtualization server for the
solution. The idea is to create a complete working
install
of dbmail/postfix as a virtual server that can be
simply
deployed to new machines as our hardware requirements
grow.
So now rather than taking the time to build a
completely
new box, about 4 hours, I can build a new box by simply
installing vmware and copying an my virtual server
over, 15
mins. Works GREAT!
There are definite sacrifices on performance when using
a
virtual server, but for us it is worth the ease to
deployment and scalability options.
I strongly considered XEN and still might go back to
it,
but its configuration was a bit much kinda defeating
the
purpose. I can have a VMmware server up and running off
of
one rpm a couple minutes. Not open, but still free.
To setup a new server, I just install mysql/vmware on
host
os, copy the virtual dbmail appliance into vmware,
startup
and run a quick iptables config script. done :)
Anyway I thought people might be interested in this. I
would like to start a project on source forge or other
that
is linked to vmware's community virtual appliance site.
The
project would hopefully follow a release schedule with
updates to the various servers contained in the virtual
dbmail appliance. Anyone interested?
