Not sure if it was mentioned, but number of CPUs/cores in a given

this regard, surely that will change as more cores are crammed onto
the harware that people are putting in datacentres.
The cpu's in HW profiles are _virtual CPU's_ - we will never have any
control over how they relate to HW cores/sockets etc. I am not sure how
different hypervisor's present vcpu's to the guest, but I doubt that any
of it has much of an influence on how that guest performs.
I am not a virtualisation expert - but is it reasonable to expect
that
if a chip has 20 cores, one would not create 20 VMs to dole out based
on it?
That's entirely up to the cloud provider - and not something we can ever
expect to control over the provider's API.
