I am using lxc for running encryption app.
The app run "dmsetup" on devices added in the container/VM.
On running the "dmsetup create clear_sdb1" the device gets created as /dev/mapper/clear_sdb1
However similar thing does not happen when I add 2nd device sdb2.
Strangely both /dev/mapper/clear_sdb1 and /dev/mapper/clear_sdb2 starts showing up in host's device hierarchy. Should it never get created in host machine.
The /dev/mapper/control is already present in container.
I have disabled the apparmor in config file.
All the devices are given "rwm" permissions.
Will be using this setup for simulating many Virtual Machines.
/dev/mapper is the only blocker currently, since my app is working fine with one device.
