Hi,
it's me again. I am having difficulties with Virtualbox networking
since I upgraded my Linux i386 host to kernel 2.6.39.
My Laptop runs Debian unstable with a locally built kernel. I am using
the Debian packages of Virtualbox 4.0.8; my kernel build process takes
the lates module sources and builds a virtualbox-modules.deb which get
installed afterwards.
My virtual machines have their network Adapter 1 in mode "Bridged
Adapter" and interface name br0. br0 is set up using Debian methods on
the host; the host has its own IP address on br0 and is
routing/natting the VMs network traffic to the LAN with stock Linux
kernel methods. A regular ISC DHCP server is used to assign IP
addresses to the VMs.
With kernel 2.6.39 or 2.6.39.1, this network setup does not work.
br0 remains in NO-CARRIER state; vboxnet0 does not change into the UP
state. When I tcpdump on the host's br0 interface, I can see any
traffic coming in from the VM, but the host does not seem to "see" it.
For example, it doesn't answer to the VMs DHCP requests.
4: br0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN
link/ether 72:7a:1d:bd:40:ea brd ff:ff:ff:ff:ff:ff
inet 192.168.18.254/24 brd 192.168.18.255 scope global br0
5: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 0a:00:27:00:00:00 brd ff:ff:ff:ff:ff:ff
When I try the exact same thing with an exactly identically configured
kernel 2.6.38.7, everything is fine. 2.6.39's bridges themselves seem
to be OK, a KVM guest can use the very same setup just fine.
Is there anything I can do to get my networking back in virtualbox
with host kernel 2.6.39?
Greetings
Marc
