...s implementation for KVM. Most of it was done by Ingo Molnar, I just moved things around a bit. I don't think there's a measurable performance benefit just yet but there are a few more optimizations that I think we can get in time for 2.6.23 that will be measurable. Regards, Anthony Liguori

...These patches probably break guest save/restore. Need a generic way to get additional save/restore callbacks in the kernel (perhaps the in-kernel APIC series addresses this already?). The latest versions of these patches are available at: http://hg.codemonkey.ws/kvm-paravirt Regards, Anthony Liguori

From: Anthony Liguori <aliguori at amazon.com> If MSI-X initialization fails after setting msix_enabled = 1, then the device is left in an inconsistent state. This would normally only happen if there was a bug in the device emulation but it still should be handled correctly. Cc: Matt Wilson <msw at amazon.co...
