VirtualBox NAT on Ubuntu 13.04 intermittently broken

Reported by: Jeremy@… Owned by:
Component: network/NAT Version: VirtualBox 4.2.16
Keywords: Cc:
Guest type: Windows Host type: Linux


Guest can typically ARP, DHCP, but after that ARP resolution fails, ergo networking stops (unable to ping default gateway). Without intervention, it will start working again, and then intermittently stop working.

This affects both Oracle and Ubuntu provided VirtualBox 4.2.x versions since 14.

NIC trace pcaps show guest packets transmitting ARP, but not getting any response from the virtual NAT gateway. Then for unknown reasons it starts working for a while.

Replying to Hachiman:

Could you please attach log file?

Thanks. I wasn't sure whether I would need to provide log, NIC trace pcap, corefile, or some combination of those.

Do you have MS iSCSI service started in the Windows guest per chance?

This should have been fixed in 4.3.12.
