[lxc-users] lxc-create with loop backingstore: bdev.c: do_loop_create: 2023 Error creating filesystem

[tapczan]

Hello

I use PPA version of LXC subsystem on ubuntu trusty. I simple
container creation generates a error:

root at trusty:~# lxc-create -n test -B loop --fssize 20G --fstype ext4
-t download -- -d ubuntu -r trusty -a amd64
lxc-create: bdev.c: do_loop_create: 2023 Error creating filesystem
type ext4 on /var/lib/lxc/test/rootdev
lxc-create: lxccontainer.c: do_bdev_create: 932 Failed to create
backing store type loop
lxc-create: lxccontainer.c: do_lxcapi_create: 1408 Error creating
backing store type loop for test
lxc-create: lxc_create.c: main: 274 Error creating container test

I've tested lxc in versions: 1.1.3, 1.1.2 and the result is the same.
On standard trusty version 1.0.7 it works fine.

Is there any change of using lxc-create with loop backingstore in
newest lxc versions?
