Malformed ethernet packets with host interface networking

Post by franktarz »

I am runing VirtualBox 1.5.51 on a Solaris 10 system. I'm using the TUN/TAP and brdgadm drivers to set-up ethernet tunneling.

I have installed WinXp as a VirtualBox guest with a single NIC using host interface networking.

I cannot seem to get networking in the guest OS to work correctly.

If I capture ethernet traffic from the Solaris host I see stuff like below. The MAC address for the VirtualBox NIC is correct but the rest of the packet seems malformed.

I have very little experience with the TUN/TAP and brdgadm drivers so I don't know how to correctly test them.

Can anyone help?
