Do you think this change will solv the issue?
No need for xen_vcpu_init anymore:
- the RTC emulator doesn't have any periodic timers continuously running
even in absence of guest interactions anymore;
- qemu_dummy_start_vcpu takes care of disabling TCG for us, so we don't
need to do it manually here.
