Hi John e1000 cards are supported by DNA only, e1000e cards are supported by DNA and ZC, please note that: - even if you use DNA/ZC drivers in the guest os, you still have all the overhead in the host os/hypervisor (for 10G we use PCI-passthrough/Direct-IO with DNA/ZC for line-rate on VMs, or ZC with a master process on the host sending packets to a sw queue for zero-copy host-guest communications) - you will not get a significative performance improvement at the rates supported by e1000 cards - in most case e1000 cards are not able to do line-rate anyway
