Let's make clear about it.
1. You use linux guest, don't you?
2. You boot HVM with eepro100 driver in linux?
3. You ping HVM guest and failed after 5 minutes? Do you get "no available
buffer" message in guest?
If so, this is a known issue, I met it when I use ping in linux guest with
eepro100 driver. When I changing to e100 driver with an interrupt fixing patch,
"ping" works well.
So I don't know how native performs.
Firstly, I want to know whether you get error info while you use
"ping" in guest.
BTW: while "ping" failed with "no available buffer" info, network doesn't hang.
