NAMEocf_heartbeat_VirtualDomain - Manages virtual domains through the libvirt virtualization frameworkSYNOPSISVirtualDomain [start | stop | status | monitor | migrate_to | migrate_from | meta-data | validate-all] DESCRIPTIONResource 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. SUPPORTED PARAMETERSconfigAbsolute 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 resolvable 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_host_memory If set true, the agent will detect the number of *Max
memory* from virsh, and put it into the host_memory 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) unset_utilization_cpu If set true then the agent will remove the cpu
utilization resource when the monitor is executed.
(optional, boolean, default false) unset_utilization_host_memory If set true then the agent will remove the host_memory
utilization resource when the monitor is executed.
(optional, boolean, default false) unset_utilization_hv_memory If set true then the agent will remove the hv_memory
utilization resource when the monitor is executed.
(optional, boolean, default false) 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) backingfile When the VM is used in Copy-On-Write mode, this is the
backing file to use (with its full path). The VMs image will be created based
on this backing file. This backing file will never be changed during the life
of the VM.
(optional, string, no default) stateless If set to true and backingfile is defined, the start of
the VM will systematically create a new qcow2 based on the backing file,
therefore the VM will always be stateless. If set to false, the start of the
VM will use the COW (<vmname>.qcow2) file if it exists, otherwise the
first start will create a new qcow2 based on the backing file given as
backingfile.
(optional, boolean, default false) copyindirs List of directories for the virt-copy-in before booting
the VM. Used only in stateless mode.
(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) start_resources Start the virtual storage pools and networks used by the
virtual machine before starting it or before live migrating it.
(optional, boolean, default false) SUPPORTED ACTIONSThis 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.
