How do run an arm lxd container on my intel host

Question

Following the normal procedure yields this error:

lxc_start - start.c:start:1438 - No such file or directory - failed to exec /sbin/init

Answer 1

Running arm containers on an intel host is possible using qemu but it does not work out the box and requires copying a qemu file onto the container rootfs

Steps for a 16.04 host.

Assuming lxd-client package is installed.

sudo apt-get install qemu-user-static
lxc launch ubuntu:15.04/armhf arm1

Should output:

Creating arm1
Starting arm1
error: Error calling 'lxd forkstart arm1 /var/lib/lxd/containers /var/log/lxd/arm1/lxc.conf': err='exit status 1'
Try `lxc info --show-log arm1` for more info

To fix run:

sudo cp /usr/bin/qemu-arm-static /var/lib/lxd/containers/arm1/rootfs/usr/bin
# then start it again.
lxc start arm1

then you can log in by:

lxc exec arm1 bash
