cloud-hypervisor describes vCPUs as x2apic MADT entries; without CONFIG_X86_X2APIC the kernel ignored them and every x86_64 guest booted with a single CPU regardless of --cpus. DEFERRED_STRUCT_PAGE_INIT moves the largest silent stretch of early boot onto all CPUs (x86 guest boot 202 -> 130 ms); measured as a wash on arm64 (VZ and KVM), so only x86 takes it.
