That's the situation we've got already - we compile Xen and  KVM to use
the rtl8139 nic since that's the best lowest-common denominator. It was
a barely passable approach so far, but with VirtIO it is now past its sell
by date and we have to key off os type/variant. If we don't then we'll
be limiting guests to 1/100 of the their potential performance. Not cool
