While SeaBIOS only uses synchronous SMI delivery through port 0xb2, OVMF also uses APIC delivery, and it is buggy.
This is enough to run OVMF with SMM enabled and multiple processors, up to a UEFI shell, but it literally takes minutes to get there. However, the same behavior is visible with KVM disabled, so it may be a firmware bug instead.
