It seems the file /.oldroot//var/run/libvirt/lxc/dwj-lnx-dev/meminfo isn't
exist.

I can't reproduce this problem on my workstation.So I can only give you
some advice, change the codes, make lxcContainerMountProcFuse always return
successfully. You will be able to start lxc domain now. And on host, let's
have a look at the file /var/run/libvirt/lxc/dwj-lnx-dev/meminfo.

ll /var/run/libvirt/lxc/dwj-lnx-dev/
cat /var/run/libvirt/lxc/dwj-lnx-dev/meminfo

Thanks!
