No, unfortunately it is not possible at this stage of the release cycle.
But users can still use QEMU 2.5 (as soon as it is released, which
should be in a couple of months) with Xen 4.6 as there is not a strong
tie between QEMU releases and Xen releases.

Yes. You cannot set MPIDR values for the KVM, because upon reset they are

ABM is only implemented as a single instruction set by AMD; all AMD
processors support both instructions or neither. Intel considers POPCNT
as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's
ABM flag to indicate support for both POPCNT and LZCNT. It has to be
added to Haswell

This patch adds a way to specify multiple volfile servers to the gluster
block backend of QEMU with tcp|rdma transport types and their port numbers.
Problem:
Currenly VM Image on gluster volume is specified like this:
file=gluster[+tcp]://server1[:port]/testvol/a.img

I think the first ten patches are a about as large a bite as we can chew
and commit quickly. If you split them off, I can try to get them in
quickly, and in parallel continue reviewing the rest of your series.

It is based on kernel API which is not released yet, therefore i post it

Routing add/update functions now take additional PCIDevice pointer. Also,
in order to provide backwards compatibility with older kernels, a new
kvm_msi_flags global variable is provided, and machines, wishing to use
new MSI features, must set appropriates flags in it.
