Hi Giuseppe,

Please test nova version 2:21.2.4-0ubuntu2.7~ppa3 in the PPA.
(It's finished building and should be published in some time.)

The config change should be something along the lines of
`cpu_model_extra_flags = -xsaves` 


I couldn't test the package/functionality yet, but all of the
build-time unit tests have passed (just like official packages).

Please let us know how it goes.

Thanks,
Mauricio
