Public bug reported:
Hi,
using Ubuntu 22.04, Kernel 5.15.0-58-generic, LXD 5.10-b392610, iproute2
5.15.0-1ubuntu2
I ran into the problem that a virtual LXD container with an macvlan network
interface mapped to the hosts ethernet adapter works as expected with all other
machines in the LAN, including getting an IP address assigned by the DHCP
server. But it cannot be reached from the HOST machine itself.
My first guess was that LXD does not set the macvlan into bridge mode, but
leaves it in the default private mode, which would explain the problem. But
LXD's source code showed that it sets the mode to bridge and uses iproute2's
ip program to set the interface.
I therefore tried commands like
ip link add name blubb address 02:4e:a6:27:01:07 link enp4s0 type
macvlan mode bridge
ip link add link enp4s0 name sugar type macvlan mode bridge
which succeed without error message. But ip link show reports
9: blubb@enp4s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
link/ether 02:4e:a6:27:01:07 brd ff:ff:ff:ff:ff:ff
10: sugar@enp4s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
link/ether 26:99:d1:52:ba:e0 brd ff:ff:ff:ff:ff:ff
in both cases "mode DEFAULT", where I would expect „bridge“. Same with
the interface assigned to the LXD virtual container.
Shouldn't this show the mode used in the ip link add command instead of
DEFAULT?
- I reported the problem to the iproute2 maintainer, but he told me to report
to net...@vger.kernel.org
- on net...@vger.kernel.org I did not get a response
- Kernel.org bugzilla tells to report problems not to kernel.org, but to
the distributions bug system
regards
