walterw Posted March 13, 2018 Report Share Posted March 13, 2018 I am trying to launch a container with lxd and am not having any such luck. These are the steps I followed: https://wiki.gentoo.org/wiki/LXD 1. install lxd (I did not install criu and will add that for a future build) 2. manually configure kernel for lxd (I didn't do ebuild lxc or ebuild criu) 3. lxd group / user didn't exist, so I created it 4. add myself to that group 5. started lxd 6. initialized lxd (the order on the gentoo website says otherwise, but I couldn't do it in that order) 7. lxd automatically setup the network interface via the lxd service, so I didn't have the net.lxbr0 to worry about 8. images repository already existed, I just chose alpine linux since it was tiny lxc launch images:alpine/3.4 Creating the container Container name is: peaceful-racer Starting peaceful-racer error: Failed to run: /usr/sbin/lxd forkstart peaceful-racer /var/lib/lxd/containers /var/log/lxd/peaceful-racer/lxc.conf: Try `lxc info --show-log local:peaceful-racer` for more info lxc info --show-log local:peaceful-racer Name: peaceful-racer Remote: unix:// Architecture: x86_64 Created: 2018/03/13 10:24 UTC Status: Stopped Type: persistent Profiles: default Log: lxc 20180313102453.772 WARN lxc_monitor -

walterw Posted March 13, 2018 Author Report Share Posted March 13, 2018 Thanks, that fixed it - I followed the gentoo docs and not the funtoo ones. Link to comment Share on other sites More sharing options...
