we can definitely help with the integration
as long as you have the hyperv
drivers for the guest in source format

another option might be to use the e1000 emulation
in hyperv.

but in any case don't hold your breath for performance,
because chances are that the network I/O path in the
hypervisor (hyperv in this case) is not able to
sustain the data rates that netmap can generate.

See the paper at this link to see what we did for QEMU/KVM

to make it run at netmap speeds
