I'd like to play with LXC but I find the docs not very newbie-friendly.
I'm trying to follow a guide at:
https://brandonrozek.com/blog/lxc-fedora-38/
(basically because it mentions Fedora). I followed the steps closely
and rebooted, but I get the following error:
$ systemd-run --unit=my-unit --user --scope -p "Delegate=yes" -- lxc-start test
Running scope as unit: my-unit.scope
lxc-start: test: lxccontainer.c: wait_on_daemonized_start: 877 Received container state "ABORTING" instead of "RUNNING"
lxc-start: test: tools/lxc_start.c: main: 306 The container failed to start
lxc-start: test: tools/lxc_start.c: main: 309 To get more details, run the container in foreground mode
lxc-start: test: tools/lxc_start.c: main: 311 Additional information can be obtained by setting the --logfile and --logpriority options
Any insights would be welcome. (Just in case, I tried running with
SElinux turned off, but it made no difference.)
I use lxc all the time.
The last two lines are key. Add these flags: -F -o logfile. The
default loglevel is ERROR. If you want more detail include -l LEVEL.
e.g. lxc-start -n containerName -F -o containerName.log -l WARN
My experience has been that there is a disconnect between the container
and the host's bridge usually caused by misconfigured network options in
the config file or perhaps the default bridge is not up.
Here's a section from my Archlinux config. This particular bridge is
named WWW. The veth.pair isn't necessary but it puts a name on the
interface and makes it easier to identify with "ip link list (ip l l )".
The generated names, eth-VLXWORL eg. aren't helpful at all. Same
thing about hwaddr. If you don't provide a MAC one will be provided for
you.
# Network configuration
lxc.net.0.type = veth
lxc.net.0.link = WWW
lxc.net.0.flags = up
# not required
lxc.net.0.veth.pair = WWW-rch
lxc.net.0.hwaddr = 00:16:3e:00:05:10
hth, :m
