sorry too delay reply.
before we use freenas make zfs iscsi share xenserver make storage. but i test freenas zfs running cloud io slow
so now we test promox make zfs running cloud io better.
so i wish use promox make zfs share xenserver connect use. replace freenas.
so have understand ?
If I understand you correctly you want to use PVE (with ZFS) as a remote storage for xenserver?
You have 2 possibilities (probably the same as on freenas):
* NFS/CIFS (take a look at using ZFS as NFS-export on linux (it should be as simple as setting up '/etc/exports' to allow xenserver to mount a particular ZFS dataset (and maybe some tweaking of the NFS parameters for speed for n - for CIFS you can configure samba)
* iSCSI - Here it's probably best to use LIO as target provider:
