RHEL-9 is compiled with the x86_64-v2 ABI. We use this as a baseline to
select which CPUs we want to support, such that there is at least one
supported guest CPU that can be launched for every physical machine
capable of running RHEL-9 KVM.
Supported CPUs:
* QEMU models
base (QEMU internal)
host (host passthrough)
max (host passthrough for KVM,
all emulated features for TCG)
* Intel models

Deprecated CPUs:
486
athlon
Conroe
core2duo
coreduo
Icelake-Client (already deprecated upstream)
Icelake-Client-noTSX (already deprecated upstream)
kvm32
kvm64
n270
Opteron_G1
Opteron_G2
Opteron_G3
Penryn
pentium2
pentium3
pentium
phenom
qemu32
qemu64
The deprecated CPU models are subject to removal in a future
major version of RHEL.
Note: this has the effect of deprecating the default built-in CPU
model 'qemu64'. Applications using QEMU are expected to make an
explicit choice about which CPU model they want, since no builtin
default can suit all purposes.
