Network hangs after some time

Network hangs after some time

[Wagner Sartori Junior]

Hello,

I'm needin' some help. The network in guests hangs(I can't ping from
my house the guest) after some time(from 10 minutes to some hours) and
stops in one guest and the others will stopping after. I have a host
with ubuntu jaunty installed and the network is configured using
bridge... If I login in the guest(via VNC) and ping anything outside
the host, the network starts answering my pings again.

I only try the default driver and virtio for the nic and the problem persists.

Any help is welcome.

Thanks,

Wagner Sartori Junior
