Pass QEMU a physical card rather than emulation/simulation

If I do not want to bridge my eth0 and use tun or tap on the host, can I Pass my VM Guest using QEMU(with KVM) a physical card rather than emulation/simulation?

And if so, how would the host react to this? I have iptables for eth0, so if there was eth1 that went directly to to the VM guest would the host be isolated from it(for security)?

You can't un-attach a host nic to then use in qemu.

You can either bridge it or nat it for use in the client.
