Hi,
I was trying to find out the max number of vpcus and what is the
reason of having that. I found 2 number about it one is the recommend
max by KVM which is 160 and the other number was 255. Can someone
tell me what are the reasons of this limitations? Why 160 is the
recommended max and why the max number is 255?
Thank you.

255 comes from apic limitation and 160 because that's the max someone
has ever tested ?
