This release was cooking for far too long, and as a result there are
plenty of changes. Windows XP SMP performance is much improved for
AMD hosts or Intel hosts without FlexPriority (performance with
FlexPriority should already be very good). There are many smp and
timekeeping fixes included. mmio coalescing and async virtio-block
should improve mmio performance. SLES 10 is supported as host.
on our centos-5 host we run our guests (as you suggested) with
clocksource=acpi_pm does it still required with this release?
kvm-70 do not compile on centos-5 kernel-2.6.18-53.1.21.el5, there are 2
warning (which would be nice to fix anyway), but the real problems is here:
