I see no need for the change. In short: If live migration is not a concern, or if your cluster consists of nodes with identical CPUs and microcode versions, it is advisable to set the CPU type to 'host.' In theory, this configuration will provide maximum performance for your guests.
For scenarios involving live migration between different CPUs, it is recommended to use the default 'kvm64,' which is compatible with essentially all x86_64 host CPUs.
Sorry for posting at the wrong place. It's a nice to have feature.
I make use of the live migrations when I do hardware maintenance. I would rather make use of the new CPU types in the future, it eventually seems more future-proof, so an option for at least the new default CPU type would be a bonus. I can use kvm64 or change post-install.
thank you again for the awesome scripts!
With version 8 Proxmox added new default CPU types. I suggest an addition in the setup wizard for:
x86-64-v2 x86-64-v2-AES x86-64-v3 x86-64-v4
