WHAT'S NEW IN OPENSTACK GRIZZLY

Nova: Compute

®

7

Bare-metal provisioning

● Control physical servers via nova-api● Bypass hypervisors● Ability to run HPC or DBs on the cloud

● Design○ PXE to deliver machine imaging○ IPMI for power control

● Limitations○ Several incompatibilities with Quantum

®

8

Scalability

● Availability zones● Host aggregates● Cells

®

9

Scalability: Availability zones

Availability zones● Set a zone for a host● Request a zone when starting a VM● Get a list of available zones

®

10

Scalability: Host aggregates

Host aggregates● Create an aggregate based on a parameter● Associate an aggregate with a set of machines● Create a flavor associated with the parameter● Request a host using that flavor

®

11

nova-compute cells

● Nested clouds● Geo-distribution● Separation of cell-scheduling from host-

scheduling

● Design○ Separate DB per cell○ Inter-cell communication via RPC○ Tree-structure, with "nova-api" only in root

nova-conductor

● Remove direct connection between nova-compute (and therefore VMs) and db

● Security and scalability

● Design○ nova-conductor is a separate service reachable via MQ○ Multiple conductors to spread the load

®

14

Database performance

Archiving a database● Moving a machine● Log archiving● Garbage records

nova-manage db archive_deleted_rows --max_rows MAX_ROWS

®

15

Evacuation

● Moving to a new host on host failure

nova evacuate SERVER_ID TARGET_HOST

®

16

Other nova improvements

● Instance action tracking via API● Network adapter hot plugin● File injection without mounting guest

filesystem
