Please do you mind giving me more insight on the logic currently implemented 
and maybe what is wrong with it? It will be important for me since what I'm 
doing is research work. 

How do the values evc->size and xfeature_mask relate to the source and target
processor xstates (or xstate management)?

Xen version 4.18.3-pre
My CPU is : Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz
I'm running Ubuntu 20.04.

Yes I am able to capture them. You can find them below.

I don't have any CPUID overrides. I just let the guest (Ubuntu server) use
whatever xen gives.
