Hello,
I'm using libvirt to manage my KVM instances. I created a VM with
qemu-kvm-0.12, later upgraded to qemu-kvm-0.14 and took a snapshot using
libvirt. As the original VM was created with qemu-kvm-0.12, libvirt
stored pc-0.12 with its XML data. Now I upgraded to qemu-kvm-1.1.2, where
VFIO implements platform independent stuff such as
a PCI driver, BAR access (via read/write on a file descriptor
or direct mapping when possible) and IRQ signaling.
The platform dependent part includes IOMMU initialization
and handling. This patch implements an IOMMU driver for VFIO
which does
The series includes IOMMU implementation and necessary IOMMU groups
initialization.

This patch initializes IOMMU groups based on the IOMMU
configuration discovered during the PCI scan on POWERNV
(POWER non virtualized) platform. The IOMMU groups are
to be used later by VFIO driver (PCI pass through).
It also implements an API for mapping/unmapping pages for
guest PCI drivers and

Virtual interrupt delivery avoids KVM to inject vAPIC interrupts

Add RFS support to virtio network device.
Add a new feature flag VIRTIO_NET_F_RFS for this feature, a new
configuration field max_virtqueue_pairs to detect supported number of
virtqueues as well as a new command VIRTIO_NET_CTRL_RFS to program
packet steering for unidirectional protocols.
