P.S. Could specifying "host" instead of "CPU type" (e.g., x86-64-v3) potentially resolve this live migration issue?

Yes, you should use an abstract CPU type like x86-64-v3 if your physical CPUs are not the same model: https://pve.proxmox.com/pve-docs/chapter-qm.html#_cpu_type

Thank you, Fiona!

And have a great day!
