Proxmox and Xen Hypervisor?

what exactly would be the advantages? kvm is very good and widely used.
 
KVM is not bare-metal.
what do you mean with this? xen is also not 'bare-metal' as all guest functionality has to go through dom0 ?

What is disadvantage of Xen?
more complex to handle for example, and it is not as easy as to replace kvm with xen as simply change a config ...

Are you Kidding?
Can you tell me what "Dom0" in Xen? Why a hypervisor must writes all hardware drivers? Thus, "Xen is bare metal". Please look at https://stackoverflow.com/questions/6100949/xen-bare-metal-hypervisor
Please look at https://xenproject.org/2011/11/29/baremetal-vs-xen-vs-kvm-redux/. KVM is huge because using Linux Kernel.
If you like a Xen without Dom0 then it is ready for you: https://xenbits.xenproject.org/docs/unstable/features/dom0less.html

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
 
also please read carefully:



which is not really practical as a management layer...
I know, but they are working on it.
I'm working with XenServer and XCP-ng, but why Proxmox not thinking about target Xen customers? It is a good feature.

I knew this test but it is old: "xen 4.3.2" :(
 
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.
