commit 4cd32645fb26d39a900433c4c1dfecaac1767522 Author: Huan Xie <[email protected]> Date: Sun Jan 22 03:08:40 2017 -0800 Fix live migrate with XenServer Live migration with XenServer as hypervisor failed with xapi errors "VIF_NOT_IN_MAP". There are two reasons for this problem: (1) Before XS7.0, it supports VM live migration without setting vif_ref and network_ref explicitly if the destination host has same network, but since XS7.0, it doesn't support this way, we must give vif_ref and network_ref mapping. (2) In nova, XenServer has introduced interim network for fixing ovs updating wrong port in neutron, see bug 1268955 and also interim network can assist support neutron security group (linux bridge) as we cannot make VIF connected to linux bridge directly via XAPI To achieve this, we will add {src_vif_ref: dest_network_ref} mapping information, in pre_live_migration, we first create interim network in destination host and store {neutron_vif_uuid: dest_network_ref} in migrate_data, then in source host, before live_migration, we will calculate the {src_vif_ref: dest_network_ref} and set it as parameters to xapi when calling VM.migrate_send. Also, we will handle the case where the destination host is running older code that doesn't have this new src_vif_ref mapping, like live migrating from an Ocata compute node to a Newton compute node.
