Did you test the test? These tests require

anything. You can check with ftrace whether kvm actually emulated
pusha/popa.

Exactly. We don't support such migration.
Well that's something that has to be addressed in the virtio_net.

There's a small leak in xsave/xcr save/restore that rapidly drains all memory
during Windows XP install without FlexPriority, since that triggers qemu

These four patches were part of an optimization patchset I've been neglecting,
but are equally useful as preparation for fixing the PIC-APIC wiring issues.
Avi Kivity (4):
KVM: i8259: reduce excessive abstraction for pic_irq_request()
KVM: i8259: simplify pic_irq_request() calling sequence
Usually the vcpu-requests bitmap is sparse, so a test_and_clear_bit() for
each request generates a large number of unneeded atomics if a bit is set.
Replace with a separate test/clear sequence. This is safe since there is
no clear_bit() outside the vcpu thread.
