XenAPI support for device tagging

Registered by Hua Zhihao on 2016-09-23

Currently device tagging has been supported by libvirt and hyper-v, and original bp(virt-device-role-tagging) has been closed in Newton. For vif tagging, there isn't any difference. For disk tagging, a number of xen bus addresses will be generated and the number will be dependent on the disk's device number. A more detailed reference is at http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/misc/vbd-interface.txt;hb=HEAD

XenAPI: device tagging

Approved for ocata as this is a feature parity specless blueprint. We should get a run with the Citrix XenServer against the nova patch with this Tempest patch:

https://review.openstack.org/#/c/305120/

To make sure this passes first.

DNM: XenAPI: device tagging

We're now past the feature freeze for Ocata so I've deferred this to Pike. -- mriedem 20170128

Re-approved for Pike as a specless feature parity blueprint. -- mriedem 20170418

Now that https://review.openstack.org/#/c/333781/ is merged, does it complete the blueprint? We also need a release note for this to let people know that the XenAPI driver supports creating a server with tagged NICs and block devices. In general, we should probably also have an entry in the feature support matrix for this feature. -- mriedem 20170630

Huan Xie confirmed that this feature is complete for Pike and we can close the blueprint. We need a release note but we can mark the blueprint completed. -- mriedem 20170630
