Avi Kivitiy posted numerous KVM updates which Linus Torvalds merged into his mainline kernel source tree to be included in the upcoming 2.6.24 kernel. Avi summarized:
"Highlights include in-kernel pic/lapic/ioapic emulation, improved guest support, preemptibility, an improved x86 emulator, and a fair amount of cleanup.
"The changes outside drivers/kvm/ and include/linux/kvm*.h fix the CR8 mask definition (which is not otherwise used in the kernel) and expose some ioapic register definitions even if ioapic support is not compiled in. The diff is appended below."
