I suspect we might have been talking about 2 different things all along. What I and Arnaud have been talking about is the tap interface on the host, not the interface inside the container, which of course should be properly configured by the OS inside the container.
The OS inside the container has no way to bring the tap interface on the host up so there would be no network connectivity even though the interface on the container side was properly configured and brought up.
That would indeed make sense, but when I asked about this: On Wednesday 12 Mar 2014 17:32:27 arnaud gaboury wrote:
In that case, I'm curious to find out if you find that setting the host0 interface up in the container also brings the vb-dahlia interface up on the host?
On container :
gab@dahlia ➤➤ ~ % ip addr 2: host0: <BROADCAST,ALLMULTI,AUTOMEDIA,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 56:84:f7:39:43:c7 brd ff:ff:ff:ff:ff:ff inet 192.168.1.94/24 brd 192.168.1.255 scope global host0 valid_lft forever preferred_lft forever inet6 fe80::5484:f7ff:fe39:43c7/64 scope link valid_lft forever preferred_lft forever
gab@dahlia ➤➤ ~ # ip link set dev host0 down gab@dahlia ➤➤ ~ % ip addr 2: host0: <BROADCAST,ALLMULTI,AUTOMEDIA> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000 link/ether 56:84:f7:39:43:c7 brd ff:ff:ff:ff:ff:ff inet 192.168.1.94/24 brd 192.168.1.255 scope global host0 valid_lft forever preferred_lft forever
Now looking on host : gabx@hortensia ➤➤ ~ % ip addr 4: vb-dahlia: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast master br0 state DOWN group default qlen 1000 link/ether 8e:a4:c3:8c:cc:89 brd ff:ff:ff:ff:ff:ff inet 192.168.1.94/24 brd 192.168.1.255 scope global vb-dahlia valid_lft forever preferred_lft forever inet6 fe80::8ca4:c3ff:fe8c:cc89/64 scope link valid_lft forever preferred_lft forever
It was UP before I brought vb down. So you have your answer : yes.
...buy maybe it doesn't work the other way---bringing the interface up after boot? Anyway, this was just a matter of curiosity for me, really. I'm glad you guys got things working the way you wanted. Paul
