[Bug 1226855] Re: Cannot use open-iscsi inside LXC container


@m.morana - to my knowledge modern kernel's still don't have a namespace
aware ISCSI netlink implementation.  In an OpenStack context, I recall
seeing something about changing nova's volume attach code to use qemu's
native iSCSI support which may be a workaround for iscsiadm and native
block devices, but I haven't had a chance to look into it myself.
