Hi, In the XML documentation I found the element space_hard_limit for filesystems [1]. Is this feature implemented for any constellation? I try to use it with lxc 1.0.6-6 and libvirt 1.2.9-9 (all from debian jessie): <domain type='lxc' id='1234'> .... <devices> <emulator>/usr/lib/libvirt/libvirt_lxc</emulator> .... <filesystem type='mount' accessmode='passthrough'> <source dir='/tmp/libvirt/mnt'/> <target dir='/mnt'/> <space_hard_limit unit='bytes'>5242880</space_hard_limit> </filesystem> .... </devices> </domain> For testing I use dd if=/dev/zero of=/mnt/foo and ^C after a few gigabytes. Is this a supported configuration? If yes, I can provide some more info to reproduce, if not, I think this should be noted in the docs ("Only used by ??? driver").
