It's better for a student and for the community if the work get accepted in
the end.

So, I think that could be an intersting GSoC (implementing your ivshmem 2
proposal). However, if the qemu community isn't ready to accept a new
ivshmem, and would rather have vhost-pci based solution, I would suggest a
different project (hopefully Wei Wang can help define it and mentor): work
on a vhost-pci using dedicated shared PCI BARs (and kernel support to avoid
extra copy - if I understand the extra copy situation correctly).
