Description
===========
Using the libvirt driver and a host OS that uses cgroups v2 (RHEL 9, Ubuntu Jammy), an instance with more than 16 CPUs cannot be booted.
Steps to reproduce
==================
1. Boot an instance with 10 (or more) CPUs on RHEL 9 or Ubuntu Jammy using Nova with the libvirt driver.
Expected result
===============
Instance boots.
Actual result
=============
Instance fails to boot with a 'Value specified in CPUWeight is out of range' error.
Environment
===========
Originially report as a libvirt but in RHEL 9 [1]
Additional information
======================
This is happening because Nova defaults to 1024 * (# of CPUs) for the value of domain/cputune/shares in the libvirt XML. This is then passed directly by libvirt to the cgroups API, but cgroups v2 has a maximum value of 10000. 10000 / 1024 ~= 9.76
