[Xen-users] Xen alternatives

["Pierre \"Le Pierrot\"" <cestpierre@xxxxxxxxx>]

Hello,

I am sending this email out because I would like to know which are the
free alternatives to Xen. The requirements are: Stability/Performance,
preferably free but it can be commercial (like VMWare and Simics), can
support vast amount of virtualized machines running systems Linux and
Windows (XP/2000/2003) for an x86 computer (like a DELL PowerEdge
2850). I would've loved to end up with Xen working, but for some odd
reason, it ceases to work on the server and I can't spend more time
doing hacks on a trial'n'error in attempts to get it working -
deadline knocking on my door.

I've looked at Xen, Ms Virtual Server, Qemu, VMWare, bochs and
would've loved to try out simics but AFAIK they don't have trial
versions, we're seriously in doubt of which one to get. As a basic
analysis, we discarded bochs for stability and because of not being
solid enough. Virtual Server only runs linux with sp1 applied and has
bad performance in comparison to other alternatives. VMWare ESX (what
we were pointing at) license price is kinda high and it would take a
ton for someone of the hierarchical superiors to adjudicate budget for
it, whereas Microsoft it'd be easy, as the firm where I work at, is
like, gold partner and stuff. Last, but not least, Qemu - haven't
tried it and I've not clues about it's performance and what not. As
such, I would love to have suggestions on possible other alternatives
and if not, that you kindly share your experiences with the fore
mentioned and your personal choices. I know this is a bit off-topic,
but I surely hope the guys making xen keep doing the great work
they've done so far and that they bless me, as I do have a deadline
and can't spend any more time (Xen works wonders inside a vmware
workstation)  :-)
