Hi, I don't remember exactly, but their is a case, with lsi + scsi-block (I think)  which doesn't boot.

Qemu dev have no plan to fix that.

The nexenta pliugin uses libiscsi. You can easily verify that using 

# qm showcmd <vmid> 

if the device ref start with 'iscsi://' ==> libiscsi 

Or check the 'path' method inside the plugin source. 

for Nexenta: 

sub path { 
my ($class, $scfg, $volname) = @_; 
.... 
my $path = "iscsi://$portal/$target/$lun"; 

return ($path, $vmid, $vtype); 
} 

So this is libiscsi.
