- create separate directory '/etc/nova/nova-compute.d' where all configuration files that hold all configuration stanzas related to vmware compute driver - in simple mode we upload init script in appropriate directory and create symbolic links on it that are named like nova-compute-vmware-%cluster_id% ; script internally splits its own file name and extracts cluster name. This allow user to selectively start/stop nova-compute services. - Ubuntu init system (Upstart) requires initd service to be restarted, on CentOS we run '/bin/true' - create individual nova-compute configuration file per vSphere cluster; file is named `/etc/nova/nova-compute.d/vmware-%cluster_id%.conf', e.g. /etc/nova/nova-compute.d/vmware-0.conf - create appropriate corosync resource/primitive per nova-compute service in case of HA - currently we use same login and password for all nova-computes - set more strict access permissions (0600) on nova-compute.conf and generated files in `nova-compute.d' directory; these files hold sensitive information (credentials to vCenter server) - set 'multi_host' configuration stanza to False for both deployment modes (nonHA/HA) - add basic unit test coverage for provided functionality DocImpact Change-Id: I675dd2b7cdeacae1e703b82001dc2c855511e320 Impelements: blueprint 1-1-nova-compute-vsphere-cluster-mapping
