ocf_heartbeat_VirtualDomain

NAME

ocf_heartbeat_VirtualDomain - Manages virtual domains through the libvirt virtualization framework

SYNOPSIS

VirtualDomain [start | stop | status | monitor | migrate_to | migrate_from | meta-data | validate-all]

DESCRIPTION

Resource agent for a virtual domain (a.k.a. domU, virtual machine, virtual environment etc., depending on context) managed by libvirtd.

SUPPORTED PARAMETERS

config

Absolute path to the libvirt configuration file, for this virtual domain. (required, string, no default)

hypervisor

Hypervisor URI to connect to. See the libvirt documentation for details on supported URI formats. The default is system dependent. (optional, string, no default)

force_stop

Always forcefully shut down ("destroy") the domain on stop. The default behavior is to resort to a forceful shutdown only after a graceful shutdown attempt has failed. You should only set this to true if your virtual domain (or your virtualization backend) does not support graceful shutdown. (optional, boolean, default 0)

migration_transport

Transport used to connect to the remote hypervisor while migrating. Please refer to the libvirt documentation for details on transports available. If this parameter is omitted, the resource will use libvirt's default transport to connect to the remote hypervisor. (optional, string, no default)

monitor_scripts

To additionally monitor services within the virtual domain, add this parameter with a list of scripts to monitor. Note: when monitor scripts are used, the start and migrate_from operations will complete only when all monitor scripts have completed successfully. Be sure to set the timeout of these operations to accommodate this delay. (optional, string, no default)

SUPPORTED ACTIONS

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 90.

stop

Stops the resource. Suggested minimum timeout: 90.

status

Performs a status check. Suggested minimum timeout: 30. Suggested interval: 10.

monitor

Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 10.

migrate_from

Executes steps necessary for migrating the resource away from the node. Suggested minimum timeout: 60.

migrate_to

Executes steps necessary for migrating the resource to the node. Suggested minimum timeout: 120.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 5.

EXAMPLE

The following is an example configuration for a VirtualDomain resource using the crm(8) shell:

 primitive example_VirtualDomain ocf:heartbeat:VirtualDomain \
   params \
     config=string \
   meta allow-migrate="true" \
   op monitor depth="0" timeout="30" interval="10"
