Thanks again - few questions.
1. Can you refer to my question about tap offload features? In the guest i
can see that eth0 has all offload features disabled and cannot be enabled.
I suspect this is related to the tap configuration in the host.

VFIO virtualizes MSIX table for the guest but not mapping the part of
a BAR which contains an MSIX table. Since vfio_mmap_bar() mmaps chunks
before and after the MSIX table, they have to be aligned to the host
page size which may be TARGET_PAGE_MASK (4K) or 64K in case of PPC64.
This fixes boundar
There is a HOST_PAGE_ALIGN macro which makes sense for KVM accelerator
but it uses qemu_host_page_size/qemu_host_page_mask which initialized
for TCG only.
This moves qemu_host_page_size/qemu_host_page_mask initialization from
TCG's page_init() and adds a call for it from kvm_init().

I tried to write my own HOST_PAGE_ALIGN to fix VFIO and found out
it is already there but does not work for KVM so here are 2 patches

The vfio-pci initfn will currently succeed even if DMA mappings fail.
A typical reason for failure is if the user does not have sufficient
privilege to lock all the memory for the guest. In this case, the
device gets attached, but can only access a portion of guest memory
and is extremely unlikely

This patch adds the Single Precision VSX Scalar Fused Multiply-Add
instructions: xsmaddasp, xsmaddmsp, xssubasp, xssubmsp, xsnmaddasp,
xsnmaddmsp, xsnmsubasp, xsnmsubmsp.
The existing VSX_MADD() macro is modified to support rounding of the
intermediate double precision result to single precision.
This patchs adds the VSX Logical instructions that are new with
ISA V2.07:
- VSX Logical Equivalence (xxleqv)
- VSX Logical NAND (xxlnand)
- VSX Logical ORC (xxlorc)

This patch adds the Move To VSR instructions (mfvsrd, mfvsrwz)
and Move From VSR instructions (mtvsrd, mtvsrwa, mtvsrwz). These
instructions are unusual in that they are considered a floating

This patch adds a flag to identify those VSX instructions that are
new to Power ISA V2.07. The flag is added to the Power 8 processor
