Thanks Chenzeng.
A major use case for invoking the parent PreActivity before the child PreActivity, is having the Protection Plugin contact with the VM guest, before handling images, volumes, and network. Are there use cases for child activity before the parent activity, which are not covered by the PostActivity? (in the context of any operation: protect, restore, and delete) --Yuval ________________________________ From: 陈曾 <chenzeng...@163.com> Sent: Friday, May 6, 2016 9:50:44 AM To: openstack-dev@lists.openstack.org Subject: Re: [openstack-dev] [smaug] Smaug Operation Workflow Hi yuval, Your design is very good. I have one question that what's the order of parent's PreActivity and children's PreActivity. Maybe we should run parent's PreActivity after children's PreActivity. The attached pdf is my understanding of your design. I have put the children's PreActivity before parent's. Please take a look at it. Thanks! Very good work! best wishes! chenzeng ------------------------------------------------------------------------------------------------------------------------------------------------- This email and any files transmitted and/or attachments with it are confidential and proprietary information of Toga Networks Ltd., and intended solely for the use of the individual or entity to whom they are addressed.
