I thought I would reply again with the key point from my earlier mail
highlighted, and go a bit further.  The first thing to go wrong in
this was:

2018-05-30 22:12:49.320+0000: xc: Failed to get types for pfn batch (14 = Bad 
address): Internal error
2018-05-30 22:12:49.483+0000: xc: Save failed (14 = Bad address): Internal error
2018-05-30 22:12:49.648+0000: libxl-save-helper: complete r=-1: Bad address

You can see similar messages in the other logfile:

2018-05-30 22:12:49.650+0000: libxl: 
libxl_stream_write.c:350:libxl__xc_domain_save_done: Domain 3:saving domain: 
domain responded to suspend request: Bad address

All of these are reports of the same thing: xc_get_pfn_type_batch at
xc_sr_save.c:133 failed with EFAULT.  I'm afraid I don't know why.

There is no corresponding message in the host's serial log nor the
dom0 kernel log.

Ian.
