[Users] openvz ploop images on moosefs mount

Hi,

has anybody tried using the new ploop storage for openvz images together 
with moosefs ( http://www.moosefs.org/)?

ploop mount -d /dev/ploop0 /mfs-mount/root.hdd
Adding delta dev=/dev/ploop0 img=/mfs-mount/root.hdd (rw)
PLOOP_IOC_ADD_DELTA /mfs-mount/root.hdd: Invalid argument

In syslog I find:
kernel: File on FS without backing device

I thought it might be because ploop needs direct-io (right?), but 
mounting with direct-io enabled seems not to be supported by moosefs:

mfsmount -o direct_io /mfs-mount
mfsmaster accepted connection with parameters: read-write,restricted_ip 
; root mapped to root:root
fuse: unknown option `direct_io'

Has anybody got it working somehow? :)

Btw: I'll also post this question to the moosefs mailinglist as I'm 
pretty sure the devs there might have interesting answers too.

Corin
