First of all thank you for your awesome work! I really appreciate using vagrant-lxc.
This issue is actually a question. I wonder if BTRFS supports NFS, I couldn't find any useful information about it and wondered if you had a tipp.
- I've setup a Ubuntu 14.04 VM (
parallels/ubuntu-14.04), installed LXC and formatted the/system with BTRFS. - In this VM I'm running a VM based on
fgrehm/trusty64-lxc.
Everything seems to boot up well except when I enable the NFS shared folder. I followed the FAQ and according to this I've changed /etc/apparmor.d/lxc/lxc-default to:
profile lxc-container-default flags=(attach_disconnected,mediate_deleted) {
#include <abstractions/lxc/container-base>
# the container may never be allowed to mount devpts. If it does, it
# will remount the host's devpts. We could allow it to do it with
# the newinstance option (but, right now, we don't).
# deny mount fstype=devpts,
mount fstype=nfs,
mount fstype=nfs4,
mount fstype=rpc_pipefs,
}
When booting up the VM I receive this message
exportfs: /vagrant/vms/vagrant-providers-symfony does not support NFS export
==> default: Mounting NFS shared folders...
SNIP!
mount -o 'vers=3,udp' 10.0.3.1:'/vagrant/vms/vagrant-providers-symfony' /mnt/vagrant-QX58m0GAW2Wn
SNIP!
mount.nfs: access denied by server while mounting 10.0.3.1:/vagrant/vms/vagrant-providers-symfony
On the "host" /var/log/syslog shows the following entries.
Apr 19 16:59:51 vagrant rpc.mountd[1241]: authenticated mount request from 10.0.3.185:952 for /vagrant/vms/vagrant-providers-symfony (/vagrant/vms/vagrant-providers-symfony)

Apr 19 16:59:51 vagrant rpc.mountd[1241]: Cannot export /vagrant/vms/vagrant-providers-symfony, possibly unsupported filesystem or fsid= required
Do you have an idea how I could get the shared folder to work properly? Preferably with using NFS.
Thanks again!
