This release fixes two critical issues:
1) Performance was bad in previous versions (QEMU would stay at 80% + even
when the guest was idle). Root cause was a latent KVM bug that was not
exposed with the original interrupt model. Namely, interrupts were not
checked during light-exit (see

The current code is geared towards using a user-mode (A)PIC. This patch adds
an "irqdevice" abstraction, and implements a "userint" model to handle the
duties of the original code. Later, we can develop other irqdevice models
to handle objects like LAPIC, IOAPIC, i8259, etc, as appropriate

The VCPU executes synchronously w.r.t. userspace today, and therefore
interrupt injection is pretty straight forward. However, we will soon need
to be able to inject interrupts asynchronous to the execution of the VCPU
due to the introduction of SMP, paravirtualized drivers, and asynchronous

For your information if another dummy people report my strange behaviour:
the solution was the loading kvm and kvm-amd modules...
Sorry

VMX definitely does not (IIUC). I don't know enough about SVN to say for sure,
but my gut tells me that its not
