Hi Okky,

Thanks for your reply, output of machine 1 (the source machine) and 
machine 2 (the target):

Machine 1:

Machine 2:

NAME                                               USED  AVAIL  REFER  
MOUNTPOINT
rpool/zones                                       7.59G  18.8G    32K  
/rpool/zones
rpool/zones/zone_roots                            7.59G  18.8G  7.59G  
/rpool/zones/zone_roots


So yes, the ""myzone" ZFS data set does not exist, but wouldn't this get 
created when the zone is attached? Alternatively, creating the dataset 
manually before the zone is attached does not change the behaviour, and 
I get the same error message.

I'm clearly getting something confused here, any ideas?
