Public bug reported:
It appears lxd fails to start on a system running the linux-kvm kernel,
due to a netlink issue:
Oct 13 20:40:53 builder lxd-bridge.start[448]: RTNETLINK answers: Operation not
supported
Oct 13 20:40:53 builder lxd-bridge.start[448]: Failed to setup lxd-bridge.
Oct 13 20:40:53 builder systemd[1]: lxd-bridge.service: Main process exited,
code=exited, status=2/INVALIDARGUMENT
I don't know what specific operation lxd is looking for with its bridge.
strace shows:
[pid 531] open("/usr/lib/ip/link_bridge.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT
(No such file or directory)
[pid 531] sendmsg(3, {msg_name(12)={sa_family=AF_NETLINK, pid=0,
groups=00000000},

[pid 531] write(2, "RTNETLINK answers: Operation not"..., 43RTNETLINK

lxd is important to support on linux-kvm.
