Dietmar, can we add some property to a storage plugin and check it ? (I really don't like theses hardcoded values)

yes, state can't be writen like this on the iscsi volume.(maybe not impossible). use external file should be more easy.

I'll check the code, I seem to miss some parameters in the json.

OK first problem is the QemuServer.pm and the hardcoded cases where 
snapshot is possible: 
die "can't snapshot volume '$volid'\n" 
if !(($scfg->{path} && $volname =~ m/\.qcow2$/) || 
($scfg->{type} eq 'rbd') || 
($scfg->{type} eq 'sheepdog')); 

If you add nexenta then snapshotting works fine except you want to 
include state. 

TASK ERROR: VM 102 qmp command 'snapshot-start' failed - Could not open 
'iscsi://10.255.0.10/iqn.1986-03.com.sun:02:9f6ecfd8-ea21-cc24-fd90-f8a0d8edf0b6/6' 

Deleting snapshot results in: 
TASK ERROR: Nexenta API Error: More items found in D-Bus signature than 
in Python arguments at /usr/share/perl5/PVE/Storage/NexentaPlugin.pm 
line 34.
