Ok, found the problem and bug: - it seems with NFS v4 everyone and their fuckin dog can mount a share, even with an address not in the exports ACL (input/output errors on everything then on)
- Cloudstack (Adv+SG) uses the guest network instead of the management network to mount the share (most likely a bug) - can't allow the guest network to mount nfs, any user VM could mount it and read/write everything. Will open a bug report. -- Sent from the Delta quadrant using Borg technology!
