Comparison of AMT vs ASF Capabilities
Network Performance Impact
The installation of a virtualized appliance causes the NIC device to dynamically change device IDs. This
should result in “New hardware found” messages and the installation of different virtual drivers.
Intel NIC Vendor ID, Device ID, and description string:
Physical - 8086 / 104A “Intel 82566DM Gigabit Network Connection”
Virtualized - 8086 / 10B7 “Intel Pro/1000 vVE Network Connection”
This causes redirection of user networking I/O to the virtual partition, which can impact network traffic
performance. Third party appliances that inspect network packets will impact this further.
