I am trying to track down if my issues with libvirt_lxc are down to me missing the changes in libvirt or the kernel (libvirt 1.2.9, Linux 3.16.3) that are mentioned from this thread. I am looking for either the git changes in both libvirt and linux (currently failing to find either) or if indeed these changes made it upstream? Is anyone able to point me in the right direction please? This is for the issue I have with proc remounting while using <idmap> which I believe is the problem talked about in this thread, but I could well be barking up the wrong tree. virsh # start testvm error: Failed to start domain testvm error: internal error: guest failed to start: Failed to re-mount /proc/sys on /proc/sys flags=1021: Operation not permitted Many thanks, Adrian
