[lxc-users] lxc-attach shows hosts root fs instead of containers'

Hi, I created a basic archlinux container (using almost the template): lxc-create -n test -t archlinux I now start the container lxc-start -n test In another shell, I attach inside it: lxc-attach -n test [/bin/bash] And I see the root file system of the host! However, when I get into the ma

Re: [lxc-users] lxc-attach shows hosts root fs instead of containers'

this happen with fedora as well, i tested with lxc 1.0, (make rpm , with --prefix=/usr, --enable-python), on fedora 20. for me if i ssh into the container, i can see the container rootfs, but if i attach using lxc-attach -n /bin/bash , it shows the host rootfs regards ranjib On Tue, Feb 25, 2014
