The big change is of course full swapping support, finally delivering
the full range of Linux memory management operations to kvm. You will
need a 2.6.27 host to use this functionality, however.
Other noteworthy changes: speedups of both virtio-net and qcow2 with
cache=off. Two important works-in-progress: device assignment (not
usable yet, as dma support is still missing) and the real-mode emulation
framework.
Changes from kvm-72:
- merge qemu-svn
- improve qcow2 performance with cache=off
- ide fixes
- ia64 external module (Xiantao Zhang)

- fix pit timer interrupt injection logic (Marcelo Tosatti)
- paravirt guest: query tsc frequency from host (Glauber Costa)
- pci device assignment (Amit Shah, Ben-Ami Yassour, Weidong Han)
- still lacking dma
- fix large page crash on z10 mainframes (Christian Borntraeger)
- stack usage reduction (Dave Hansen, Sheng Yang)
- code cleanup (Sheng Yang)
- fix debug register corruption on Intel hosts (Marcelo Tosatti)
- fix -no-kvm-irqchip
- fix irq acking on pic reset (Marcelo Tosatti)
- ignore spurious timer interrupt acks

- simpify irq injection (Amit Shah)
- dummy irq ack notifier for ia64 (Xiantao Zhang)
Notes:
If you use the modules bundled with kvm-73, you can use any version
of Linux from 2.6.16 upwards. You may also use kvm-73 userspace with
the kvm modules provided by Linux 2.6.22 or above. Some features may
only be available in newer releases.
