One customer of our partner reported he failed to install a VM using rhel9.4:

He got this message when launching the VM:

"

ERROR    internal error: QEMU unexpectedly closed the monitor (vm='ny5-dtlvm-build-arm01'): 2024-05-23T11:43:59.005476Z qemu-kvm: warning: CPU model cortex-a57-arm-cpu is deprecated – use 'host' / 'max'

If using --cpu=host

ERROR    unsupported configuration: CPU mode 'host-model' for aarch64 kvm domain on aarch64 host is not supported by hypervisor

"

So while we support the so-called "host" cpu model at qemu level, it seems the same terminology is not used at virt-install level and --cpu host does not work.

The qemu message is misleading in the respect. So we need to clarify and properly document this to avoid this kind of report.  --cpu option is not documented in rhel "Configuring & Managing Virtualization" doc for rhel9
