RE: [Xen-users] KVM vs XEN source

Xen has some very large deployments (Amazon EC2).  It's not easy to say what kind of market share KVM has these days, assuming a minority of all Red Hat customers actually use it.  I think it's fair to say KVM has an uphill battle to fight with the likes of Xen and VMWare on the market.  Ultimately if both products are very good, small margins of performance won't matter to most users.


Red Hat took a big gamble on a niche virtualization technology, since in my opinion they don't have the market muscle to make KVM a dominant player.  Time will tell how this works out for them.  I've also seen posts from people saying (in effect):  "You should try out KVM, it is very good."  I believe they're probably right.  The problem for KVM supporters is they haven't given me any reason to switch.  (And before someone mentions it, I don’t count dom0 support as a reason, since I have no business requirement to run RHEL 6 on each piece of hardware I own.)

Given enough effort, anything is possible.  At this point in time, I definitely think Xen is better than KVM.  If Xen development stalled and KVM development continued to move forward, KVM could become better at some point in time.  Predications tend to be tricky, though.  About 50 years ago, everybody assumed we would all drive flying cars by now.
