live_migration_flag missing in nova.conf

[Salman Baset]

To enable live migration with shared storage for VMs, the following flag needs to be added.

live_migration_flag = VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER

See http://docs.openstack.org/admin-guide-cloud/content/section_configuring-compute-migrations.html for live migration options.

state path in nova.conf is hard coded

state_path=/var/lib/nova

To take advantage of the shared file system, this parameter must be configurable.

Looks like these might also be needed for live migration:

# Number of 1 second retries needed in live_migration (integer
# value)
#live_migration_retry_count=30

# Number of times to retry live-migration before failing. If
# == -1, try until out of hosts. If == 0, only try once, no
# retries. (integer value)
#migrate_max_retries=-1

# Required for live migration among hosts with different CPU
# features (boolean value)
#limit_cpu_features=false

# Migration target URI (any included "%s" is replaced with the
# migration target hostname) (string value)
#live_migration_uri=qemu+tcp://%s/system

# Migration flags to be set for block migration (string value)
#block_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE, VIR_MIGRATE_PEER2PEER, VIR_MIGRATE_NON_SHARED_INC

# Maximum bandwidth to be used during migration, in Mbps
# (integer value)
#live_migration_bandwidth=0

Is your target for this still havana-rc1 (within next week)?
