Hi all,
very very interesting.
I have a similar problem but the other way round.
If my XP runs up tp 100% CPU usage top on the linux host reports only
33% cpu usage. I would expect around 50% because I only provide one core
for the guest. I already increased the process priority of qemu and

In the call path of kvm_get_dirty_pages_log_range(),
its caller kvm_get_dirty_bitmap_cb() passes the
target_phys_addr_t both as start_addr and the offset.
So, using int will make dirty tracking over 4G fail
completely.
Does this patch

we'll get mis-matched headers.
I think this is fundamentally wrong. User files should never directly
access kernel

Of course we should be using qemu types in
here, so

Things like this and updating to use madvise() I think all point towards

This implements optional MSI-X support in virtio_pci.
MSI-X is used whenever the host supports at least 2 MSI-X

Per-virtqueue vectors are allocated if enough vectors

This patch series implements Address Translation Service support for
the Intel IOMMU. The PCIe Endpoint that supports ATS capability can
request the DMA address translation from the IOMMU and cache the
translation itself. This can alleviate IOMMU TLB pressure and improve
the hardware performance
The PCIe ATS capability makes the Endpoint be able to request the
DMA address translation from the IOMMU and cache the translation
in the device side, thus alleviate IOMMU pressure and improve the
hardware performance in the I/O virtualization environment.

The SR-IOV spec requires that the Smallest Translation Unit and
the Invalidate Queue Depth fields in the Virtual Function ATS
capability are hardwired to 0. If a function is a Virtual Function,
then and set its Physical Function's STU before enabling the ATS.
