Hi Guys,
Having a few issues with getting vlan tagging from inside the guests working.
I am putting the eth0 of the guest into vmbr0 and then tagging from the guest with vlan 103. This is confirmed working (tcpdump on tap interface facing vm). The issue that I encounter is that doing a tcpdump on eth0 of the host I see the frame from the Guest with QinQ tagging with the management vlan as the outer.
Here is my /etc/network/interfaces file from the host:
And my brctl show
Does anyone have any ideas what might be causing this?
Thanks
Fraser
