[Bug 1219658] Re: Wrong image size using rbd backend for libvirt

[Rafael David Tinoco]

** Description changed:

  [Impact]
  
-   * [2cebfd2] libvirt: convert cpu features attribute from list to
-                        a set (LP: #1267191)
- 
-  cpu features list which is being sent to libvirt,
-  when creating a domain or calling compareCPU, must contain only
-  unique entries. Multiple issues arise when we are updating the
-  features attribute in LibvirtConfigCPU class (for example during
-  migration).
- 
-   * [b86a0e5] Fixes rdb backend image size (LP: #1219658) -> THIS!
- 
-  The original fix for bug 1219658 introduced a factor of 1024 error
-  in the resulting rbd image size -> real urgent to be fixed.
+  * The original fix for bug 1219658 introduced a factor of 1024 error
+  in the resulting rbd image size. Big impact.
  
  [Test Case]
-  
-  LP: #1267191
-  * systemctl restart openstack-nova-compute
-    Observe /var/log/nova/compute.log
  
-  LP: #1219658
-  * Testing this fix implies only in having rdb backend.
+  * To be provided.
  
  [Regression Potential]
  
-  * Tests indicate fix is running in a big production without any
- problem.
+  * Fix is running in a big production without any problem.
  
-  LP: #1267191
-  * A regression would continue to cause nova not to start (as is happening
-    today with this bug under described conditions).
- 
-  LP: #1219658
-  * RDB backend could stop working (keeping the bug will eventualy cause 
-    an outage for those who use rdb backend)
+  * RDB backend could stop working (keeping the bug will eventualy cause

  [Other Info]
  
  For rbd image backend for libvirt, the root partition will use the image
  size not 'disk' size. It lack of resize root volume in the codes.
