Which is the best Virtualization? KVM or Xen.
Please share your opinion.

Hmm, maybe google "KVM vs Xen" will get what you need?
Yes, I did but I was more interested to know a public opinion technically.
Xen.
there is no win in general or other virtualization make no sense.
Each one have their advantage and disavantages.
Every project fit better one virtualizator or another, so simple.
We've been using Xen for over 4 years, Xen HV is stable can achieve low overhead for backing up of data.
However, "marketing" has taken over KVM due to its efficient CPU utilization over Xen.
To achieve better Xen perfomance, you need to tweak their config files and enable NUMA technology which needs in depth Xen knowledge
I disagree, Xen absolutely destroys KVM in terms of CPU scheduling and separation, but yes KVM wins on marketing due to the virtio driver set, flexibility, and ram efficiency.
For long term stability, Xen wins hands down, people do not want to pay the price for Xen stability anymore though so it has no real place in this market segment.
Correct! in terms of scheduling. Most of marketing has taken over by the benchmark numbers on KVM
Thanks for your inputs! Yes, both KVM & Xen are supported by large communities and enterprises & purpose of both the virtualizations is the same. The differences are found in support for innovation, application integration, application awareness, and performance.
Xen HV is for us, we used it for around 6 years, no issue - very stable.
What price?
Have you ever NOT seen Ant online and fucking with something?
What does best stand for? Performance? Full virtualization? Cheap price? KVM plays good on full virtualization while OpenVZ is better on performance and is more cheaper.
none
Depends on your needs
I'd say xen is the best, if it only had native web-interface...
