[lxc-devel] bugs with LXC container : mount and rmmod command

Hello, 

My company is looking for migrate from OpenVz to LXC container tools but we have found some isolation problems. 

I've created a dedicated partition to share my containers in : /mnt/vmr1/ 

I've created a container with an debian debootstrap there : /mnt/vmr1/debiandebootstrap 

Then I enter into a container (lxc-console -n debiandebootstrap) and I use this specific mount command : " mount -o remount,ro / " . 

When I return to the Host , /mnt/vmr1/ is set in "read only". The mount command ran in the guest has interacted with the host. 

I have the same problem with "rmmod" command. When I try to remove some module in the guest container it remove it on the Host machine. 

Someone can help me ? 

Regards, 

Elias Olivares
