Oh, thanks Daniel! I thought the performance would be the same, just
with a different cpu name.
The CPU name is a shorthand for specifying CPU feature flags, which
in turns controls what CPU features guests can use. For example,
if your CPU has support for AES hardware encryption, you want to
be exposing this to your guests, otherwise they'll fallback to
slower software AES encryption
Daniel
Indeed.
Thanks for the lesson. ;-)
