Re: [Qemu-devel] [PATCH v1 0/5] KVM: Hyper-V VMBus hypercalls

[Andrey Smetanin]

Paolo,

Could you please force these patches applied
during current merge window. We need them
very, because they are last patches for KVM which
are required to start development of Hyper-V
VMBus devices in QEMU side.

P.S.:
We have created our public repo (based on current kvm/queue) to fetch
our latest changes in KVM code to support Hyper-V VMBus:

https://src.openvz.org/projects/UP/repos/kvm_hyperv/commits?until=refs%2Fheads%2Fvmbus_hypercall

Thanks,
Andrey
