[Lxc-users] Container remounts ro an host's mount

[Alessandro Guido]

I'm an LXC newbie and I'm trying to migrate some OpenVZ containers.
All my containers files are located under /var/lib/lxc/<ct>/rootfs and 
/var/lib/lxc is a mounted ext4 partition. Whenever I shutdown a 
container /var/lib/lxc get remounted ro. I've found this[1] thread that 
is about the same problem, however it's unclear (at least to me) how to 
prevent that from happening without changing the guest init scripts.

I'd appreciate any help :)
