Hi!

 b)

 See in P.S.
CONFIG_PARAVIRT_GUEST in arch/ia64

 a)

# CONFIG_HYPERVISOR_GUEST is not set

TO Borislav Petkov :  first [but not last :-( ] non-upgraded config . . .

TO All:

 Please, replace
CONFIG_PARAVIRT_GUEST=y
 with
CONFIG_HYPERVISOR_GUEST=y

IMHO, related not only Hyper-V, but XEN, KVM , etc.
