[Lxc-users] Bridged network interface inside Virtualbox VM

[Sean Carolan]

I feel like I'm so close to getting this working...maybe one of you can help?

Here's the scenario:

I have a virtualbox host running CentOS 6.4 x86_64.  It's got libvirt
installed and an lxc guest on it.  The guest setup went fine, and I
can even ssh into the guest from the host. The guest successfully gets
a DHCP address and has a correct routing table.  The guest can also
ping the host, but it can't ping the router or reach the internet.

Here's the command I used to create the guest:

virt-install --connect lxc:/// --name testbox --ram 512 --vcpu 1
--filesystem /containers/testbox/,/ --network bridge:br0
--noautoconsole

And the bridge info on the host:

[root at opscodelxc ~]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.08002711b9b0 no eth1
veth0
virbr0 8000.525400906d8d yes virbr0-nic

ifconfig info for br0 and eth1 on the host:

[root at opscodelxc ~]# ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 08:00:27:11:B9:B0
          inet6 addr: fe80::a00:27ff:fe11:b9b0/64 Scope:Link
          UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
           ...

[root at opscodelxc ~]# ifconfig br0
br0       Link encap:Ethernet  HWaddr 08:00:27:11:B9:B0
          inet addr:192.168.0.72  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
          ...

Has anyone gotten bridged networking to function from an lxc guest,
inside of a virtualbox VM?

I don't have the luxury of using LXC natively because I'm on a Mac.
So I have to run it from within a Linux VM.

If you know how to fix this I'd be so happy.

thanks
