Hi again, Another challenge related to same issue of empty /lib/modules from another LXC.
make[4]: *** /lib/modules/4.8.0-56-lowlatency/build: No such file or directory. Stop. CMakeFiles/ue_ip.dir/build.make:60: recipe for target 'ue_ip.ko' failed make[3]: *** [ue_ip.ko] Error 2 CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/ue_ip.dir/all' failed make[2]: *** [CMakeFiles/ue_ip.dir/all] Error 2 CMakeFiles/Makefile2:74: recipe for target 'CMakeFiles/ue_ip.dir/rule' failed make[1]: *** [CMakeFiles/ue_ip.dir/rule] Error 2 Makefile:118: recipe for target 'ue_ip' failed make: *** [ue_ip] Error 2 root@juju-0f8be6-10:/srv/openairinterface5g/cmake_targets# ls -l /lib/modules/ total 0 So, Is it possible to have the contents of the /lib/modules of the host inherited in each LXC?

However, I have the following challenge: One of the machines (M0) stipulates a kernel 4.7+ As it's known, unlike KVM, LXC makes use of same kernel of the host system and in this case (4.4.0-81) breaching thus the stipulation of M0 (4.7+). I have read that starting Juju 2.0, KVM is no more supported. Juju still supports kvm, but the old "local" provider which supported lxc/kvm is gone. You could run a kvm container from within a lxd machine with the right apparmor settings. Probably the most straight forward thing to do, though, would be to create a KVM VM yourself, install Ubuntu on it, and then manually provision it using "juju add-machine ssh:<hostname>". How could I prepare the stipulation of M0?
