Hi David,
Yeah, its a really weird frustrating problem! I'm pretty sure it is
using host IF. From the .xml
<Network>
<Adapter MACAddress="08002778517C" cable="true" enabled="true"
slot="0" type="Am79C973">
<HostInterface name="vbox0"/>
</Adapter>
Tonight I will upgrade the host gutsy from 2.6.20-16 kernel to
2.6.22-14. Maybe that has some effect. Will also upgrade guest kernel
from 2.6.22 to 2.6.23.
The last thing I was thinking is that the network card
05:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721
Gigabit Ethernet PCI Express (rev 11)
perhaps has a problem with promisc mode (and disables promisc) - but
cant really confirm this.
Else i'm pretty much at a loss. Will let you know if upgrade fixes things.
Thanks
Stefan
