Then, Why someone using Xen?what exactly would be the advantages? kvm is very good and widely used.
what do you mean with this? xen is also not 'bare-metal' as all guest functionality has to go through dom0 ?KVM is not bare-metal.
more complex to handle for example, and it is not as easy as to replace kvm with xen as simply change a config ...What is disadvantage of Xen?
Are you Kidding?what do you mean with this? xen is also not 'bare-metal' as all guest functionality has to go through dom0 ?

ok this may exists, but we would need a dom0 for management anyway?If you like a Xen without Dom0 then it is ready for you: https://xenbits.xenproject.org/docs/unstable/features/dom0less.html
this shows that xen and kvm trades blows in performancePlease look at https://xenproject.org/2011/11/29/baremetal-vs-xen-vs-kvm-redux/. KVM is huge because using Linux Kernel.
also please read carefully:If you like a Xen without Dom0 then it is ready for you: https://xenbits.xenproject.org/docs/unstable/features/dom0less.html
- No PV drivers. There is no support for PV devices at the moment. All devices need to be statically assigned to guests.
I know, but they are working on it.also please read carefully:
which is not really practical as a management layer...
I knew this test but it is old: "xen 4.3.2"ok this may exists, but we would need a dom0 for management anyway?
this shows that xen and kvm trades blows in performance
also some other benchmarks show very different results, e.g. https://major.io/2014/06/22/performance-benchmarks-kvm-vs-xen/
but this is not really a matter of performance only the single most important reason is that we already use kvm and switching to xen would be a very hard task and much work for questionable gain
but why Proxmox not thinking about target Xen customers? It is a good feature.

It is the art of products. Different performance, Different GUI and features.Thats just speculation in my opinion. Why would you switch from an allready existing xen managementsoftware to another?
Migrations usually means alot of work too.
