OCF_HEARTBEAT_VIRTUA(7) OCF resource agents OCF_HEARTBEAT_VIRTUA(7)

ocf_heartbeat_VirtualDomain - Manages virtual domains through the libvirt virtualization framework

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

Resource agent for a virtual domain (a.k.a. domU, virtual machine, virtual environment etc., depending on context) managed by libvirtd.
This resource agent may be configured for native migration if available in the cluster manager. For Pacemaker, the allow-migrate="true" meta attribute enables native migration.

config
Absolute path to the libvirt configuration file, for this virtual domain.
(unique, 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. Determine the system's default uri by running 'virsh --quiet uri'.
(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)
migration_user
The username will be used in the remote libvirt remoteuri/migrateuri. No user will be given (which means root) in the username if omitted
If remoteuri is set, migration_user will be ignored.
(optional, string, no default)
migration_downtime
Define max downtime during live migration in milliseconds
(optional, integer, default 0)
migration_speed
Define live migration speed per resource in MiB/s
(optional, integer, default 0)
migration_network_suffix
Use a dedicated migration network. The migration URI is composed by adding this parameters value to the end of the node name. If the node name happens to be an FQDN (as opposed to an unqualified host name), insert the suffix immediately prior to the first period (.) in the FQDN. At the moment Qemu/KVM and Xen migration via a dedicated network is supported.
Note: Be sure this composed host name is locally resolveable and the associated IP is reachable through the favored network. This suffix will be added to the remoteuri and migrateuri parameters.
See also the migrate_options parameter below.
(optional, string, no default)
migrateuri
You can also specify here if the calculated migrate URI is unsuitable for your environment.
If migrateuri is set then migration_network_suffix, migrateport and
--migrateuri in migrate_options are effectively ignored. Use "%n" as the placeholder for the target node name.
Please refer to the libvirt documentation for details on guest migration.
(optional, string, no default)
migrate_options
Extra virsh options for the guest live migration. You can also specify here --migrateuri if the calculated migrate URI is unsuitable for your environment. If --migrateuri is set then migration_network_suffix and migrateport are effectively ignored. Use "%n" as the placeholder for the target node name.
Please refer to the libvirt documentation for details on guest migration.
(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)
autoset_utilization_cpu
If set true, the agent will detect the number of domainU's vCPUs from virsh, and put it into the CPU utilization of the resource when the monitor is executed.
(optional, boolean, default true)
autoset_utilization_hv_memory
If set true, the agent will detect the number of *Max memory* from virsh, and put it into the hv_memory utilization of the resource when the monitor is executed.
(optional, boolean, default true)
migrateport
This port will be used in the qemu migrateuri. If unset, the port will be a random highport.
(optional, integer, no default)
remoteuri
Use this URI as virsh connection URI to commuicate with a remote hypervisor.
If remoteuri is set then migration_user and migration_network_suffix are effectively ignored. Use "%n" as the placeholder for the target node name.
Please refer to the libvirt documentation for details on guest migration.
(optional, string, no default)
save_config_on_stop
Changes to a running VM's config are normally lost on stop. This parameter instructs the RA to save the configuration back to the xml file provided in the "config" parameter.
(optional, boolean, no default)
sync_config_on_stop
Setting this automatically enables save_config_on_stop. When enabled this parameter instructs the RA to call csync2 -x to synchronize the file to all nodes. csync2 must be properly set up for this to work.
(optional, boolean, no default)
snapshot
Path to the snapshot directory where the virtual machine image will be stored. When this parameter is set, the virtual machine's RAM state will be saved to a file in the snapshot directory when stopped. If on start a state file is present for the domain, the domain will be restored to the same state it was in right before it stopped last. This option is incompatible with the 'force_stop' option.
(optional, string, no default)
shutdown_mode
virsh shutdown method to use. Please verify that it is supported by your virsh toolsed with 'virsh help shutdown' When this parameter is set --mode shutdown_mode is passed as an additional argument to the 'virsh shutdown' command. One can use this option in case default acpi method does not work. Verify that this mode is supported by your VM. By default --mode is not passed.
(optional, string, no default)

This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 90s.
stop
Stops the resource. Suggested minimum timeout: 90s.
status
Performs a status check. Suggested minimum timeout: 30s. Suggested interval: 10s.
monitor
Performs a detailed status check. Suggested minimum timeout: 30s. Suggested interval: 10s.
migrate_from
Executes steps necessary for migrating the resource away from the node. Suggested minimum timeout: 60s.
migrate_to
Executes steps necessary for migrating the resource to the node. Suggested minimum timeout: 120s.
meta-data
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 5s.

The following is an example configuration for a VirtualDomain resource using the crm(8) shell:
primitive p_VirtualDomain ocf:heartbeat:VirtualDomain \
  params \
    config= string \
  meta allow-migrate="true" \
  op monitor depth="0" timeout="30s" interval="10s" 

The following is an example configuration for a VirtualDomain resource using pcs(8)
pcs resource create p_VirtualDomain ocf:heartbeat:VirtualDomain \
  config= string \
  op monitor depth="0" timeout="30s" interval="10s"
