6280,XP guest becomes unreachable on vboxnet0 after a couple of hours,hansb,,"The XP guest on the Ubuntu Karmic x64 host works flawlessly for a while, communicating with the host on the host-only network.

After a couple of hours the ip of the guest becomes unreachable (that's what ping reports if pinged from the host side). 

Guest still runs happily and also appears to see the host ip (wrote a little script pinging the host once in a while and restarting if host gone, the script apparently still sees the host).

But the host can't see the guest IP any more.

Powering down and restarting the guest vm means it'll work again for a while, until the guest IP disappears again after a couple of hours, etc.pp.

This is an upgraded system from VB 3.1.2.
