Host and guest are both Ubuntu 14.04.
The config of the guest is:

# Distribution configuration
lxc.include = /usr/share/lxc/config/ubuntu.common.conf
lxc.include = /usr/share/lxc/config/ubuntu.userns.conf
lxc.arch = x86_64

# Container specific configuration
lxc.mount.auto = cgroup
lxc.aa_profile = lxc-container-default-with-nesting
lxc.id_map = u 0 100000 65536
lxc.id_map = g 0 100000 65536
lxc.rootfs = /home/stefanos/.local/share/lxc/grical/rootfs
lxc.utsname = grical

# Network configuration
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxcbr0
lxc.network.hwaddr = 00:16:3e:77:77:77
