Bug 1210455

The Compute service has been rebased to version: 2014.2.3 Live-migration bug fixes include: * Re-open the function of live-migration with config drive of vfat format to admin users. The option 'config_drive_format=vfat' is required explicitly in nova.conf to allow such live-migration. Live-migration with config drive on local disk is forbidden due to the bug of libvirt of copying readonly disk. However, if you use vfat as the config drive's format, live-migration works well. https://bugs.launchpad.net/nova/+bug/1246201 * Fix live migration for volume backed instances. https://bugs.launchpad.net/nova/+bug/1392773 * Fix live migration when using block devices on shared storage (for example, NFS); make sure volumes are well detected during block migration. https://bugs.launchpad.net/nova/+bug/1356552 * [Hyper-V] Fix live migration for ISO config drives. If an instance has a ISO configdrive attached, the ISO file is also moved during live migration. https://bugs.launchpad.net/nova/+bug/1322096 * [Hyper-V] Fix retrieving console logs on live migration, log files were not copied properly. https://bugs.launchpad.net/nova/+bug/1399127 * Fix live migration RPC compatibility with older versions when upgrading from RHEL-OSP 5 to RHEL-OSP 6. https://bugs.launchpad.net/nova/+bug/1402813 Important bug fixes include: * Add requirement on device-mapper-multipath - rhbz#1212558 * Allow disabling the evacuate cleanup mechanism in compute manager - rhbz#1190706 * Fix when nova-compute fails to start when guest uses passthrough - rhbz#1206238 * Fix race condition with the network cache - rhbz#1183510 * Fix inconsistent info of availability zone - rhbz#1170242 * Fix nova 'vendor' definition, impacting subscription management - rhbz#1212509 * Clean instance's directory when block migration fails - rhbz#1196364 * Fix instance root-disk size restriction with QCOW2 images - rhbz#1205808 * Fix upgrade from RHEL-OSP 5 to RHEL-OSP 6 of nova networks to handle correctly partial upgrade. https://bugs.launchpad.net/nova/+bug/1438920 * Fix nova object versioning for RHEL-OSP 6 with computes still running on RHEL-OSP 5. https://bugs.launchpad.net/nova/+bug/1408496 * [cells] Fix creating of block device mappings in the API cell, stop creating duplicates. https://bugs.launchpad.net/nova/+bug/1417239 * [numa] Correctly handle archictures having cells without memory or CPUs defined (fix the default value of config memory to 0). https://bugs.launchpad.net/nova/+bug/1418187 https://bugs.launchpad.net/nova/+bug/1385246 * Fix deletion of instances that have failed due to OpenStack Networking/Compute notification problems. https://bugs.launchpad.net/nova/+bug/1423952 * [VMware] Fix many operations when multiple compute nodes are running with different configurations (Example: each compute node is mapped to a different cluster.) https://bugs.launchpad.net/nova/+bug/1345460 * Handle correctly errors while unshelving an instance, instead of leaving the instance in an inconsistent state. https://bugs.launchpad.net/nova/+bug/1367186 * Fix handling of network interface binding failure when initializing an instance at startup. https://bugs.launchpad.net/nova/+bug/1324041 * Fix the creation of an instance with an fixed IP address. https://bugs.launchpad.net/nova/+bug/1408529 * [Hyper-V] Fix Hyper-V configdrive network injection issue fix static IP configuration. https://bugs.launchpad.net/nova/+bug/1400069 * [EC2] Make code compatible with the EC2 authentication version 4. https://bugs.launchpad.net/nova/+bug/1410622 * Fix booting an instance instance with the same network identifier for multiple NICs. https://bugs.launchpad.net/nova/+bug/1400037 * Allow non-admin tenants to attach instances to external networks from OpenStack Networking if the networks are also marked as shared. https://bugs.launchpad.net/nova/+bug/1413837 * Support macvtap for vif_type being "hw_veb". https://bugs.launchpad.net/nova/+bug/1370348
