I shouldn't have left that opening ;-) The idea with this design is to keep everything rooted on the iscsi_host, and for physical HBAs those stay assigned to init_net. With this patch set, offload drivers remain unusable in a net namespace other than init_net. They simply are not visible. By migration, I was implying the possibilty of assigment of an HBA iscsi_host into a namespace like you can do with a network interface. Such an iscsi_host would then need to be migrated back to init_net on namespace exit. I don't think it works to try and share an iscsi_host across namespaces, and manage different sessions. The iSCSI HBAs have a limited number of network configurations, exposed as iscsi_iface objects, and I don't want to go down the road of figuring out how to share those. - Chris -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
