But the behaviour of the vlc process in the guest is still the same.
I've exported additional cpu features to the guest, e.g. mmxext with kvm-84.
But no performance changes.

We don't emulate guest user mode.
Well, if guest userspace can convince its kernel to give it access to
some memory mapped I/O register, I guess it can execute repeated 'mov
ss, mmio' and starve the guest kernel.
It doesn't need a MMIO register to do that, even.

As KVM cpus runs on threads, it is possible that
we call kvm_load_registers() from a cpu thread, while the
apic has not yet fully initialized. kvm_load_registers() is called
from ap_main_loop.
This is not a problem when we're starting the whole machine together,
but is a problem for hotplug,
