Great that people are looking at host S3 side. :-)

The host S3 patch only tackles dom0/xen, and leave user level to notify 
all para-domUs and HVM domains before requesting real S3 switch. So 
basically to make a complete eco-system:
        - Need to trigger virtual S3 to HVM domain
        - Need light weight suspend/resume to para-domU (without 
domain destroy) for fast resume. Actually I sent out months ago and 
you suggested to re-send after basic host S3 is ready

Currently host S3 only imposes a last level means to force all domains 
paused in case they're not doing well.
