sd is current->domain here so the guest context is saved on the stack
rather than in the domain structure. Therefore you need to use
guest_cpu_user_regs()->eip instead. I should have thought of that
before, sorry.
The context in the vcpu's arch.guest_context will be a stale left over
from the last time the domain was rescheduled, which is why it is doing
a sched_op since it was presumably just waking up from idle.
