How does an ISP farm out 10 virtual PCs with 10

A single ethernet device can have multiple IPs. No problem.
Virtualization typically makes the virtual NIC's all have different MAC
addresses, so you're router will not know that the cable isn't plugged
into a hub/switch rather than directly connected to a single NIC
What MAC address is reported to the application is nice, but it still
doesn't solve the issue with the ARP advertisement.
How does the virtual card respond to an ARP request? I imagine that
quite a lot of low-end networking equipment expects 1 IP == 1 ARP.
I imagine that a card being used for virtualization needs to be
relatively high end. (read $100 instead of $10).
