But the similar problem exist now and without KVM. After > running x2apic enabled kernel you can't kexec kernel without x2apic > support. if the first kernel enable x2apic and intr_remapping, and second kernel has x2apic and intr_remap support. we can kexec the second kernel. restoring to original state is not possible for kdump case. maybe with minor change to your patch, you could kexec the in kexec second kernel with x2apic support.
