NAME

       ocf_heartbeat_Xen - Manages Xen unprivileged domains (DomUs)

SYNOPSIS

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

DESCRIPTION

       Resource Agent for the Xen Hypervisor. Manages Xen virtual machine
       instances by mapping cluster resource start and stop, to Xen create and
       shutdown, respectively.

       A note on names

       We will try to extract the name from the config file (the xmfile
       attribute). If you use a simple assignment statement, then you should
       be fine. Otherwise, if there's some python acrobacy involved such as
       dynamically assigning names depending on other variables, and we will
       try to detect this, then please set the name attribute. You should also
       do that if there is any chance of a pathological situation where a
       config file might be missing, for example if it resides on a shared
       storage. If all fails, we finally fall back to the instance id to
       preserve backward compatibility.

       Para-virtualized guests can also be migrated by enabling the
       meta_attribute allow-migrate.

SUPPORTED PARAMETERS

       xmfile
           Absolute path to the Xen control file, for this virtual machine.
           (required, string, no default)

       name
           Name of the virtual machine.  (optional, string, no default)

       shutdown_timeout
           The Xen agent will first try an orderly shutdown using xm shutdown.
           Should this not succeed within this timeout, the agent will
           escalate to xm destroy, forcibly killing the node. .sp If this is
           not set, it will default to two-third of the stop action timeout.
           .sp Setting this value to 0 forces an immediate destroy. .sp

           (optional, string, no default)

       allow_mem_management
           This parameter enables dynamic adjustment of memory for start and
           stop actions used for Dom0 and the DomUs. The default is to not
           adjust memory dynamically.  (optional, boolean, default 0)

       node_ip_attribute
           In case of a live migration, the system will default to using the
           IP address associated with the hostname via DNS or /etc/hosts. .sp
           This parameter allows you to specify a node attribute that will be
           queried instead for the target node, overriding the IP address.
           This allows you to use a dedicated network for live migration
           traffic to a specific node. .sp Warning: make very sure the IP
           address does point to the right node. Or else the live migration
           will end up somewhere else, greatly confusing the cluster and
           causing havoc.  (optional, string, no default)

       reserved_Dom0_memory
           In case memory management is used, this parameter defines the
           minimum amount of memory to be reserved for the dom0. The default
           minimum memory is 512MB.  (optional, string, default 512)

       monitor_scripts
           To additionally monitor services within the unprivileged domain,
           add this parameter with a list of scripts to monitor.  (optional,
           string, no default)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
           Starts the resource. Suggested minimum timeout: 60.

       stop
           Stops the resource. Suggested minimum timeout: 40.

       migrate_from
           Executes steps necessary for migrating the resource away from the
           node. Suggested minimum timeout: 120.

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

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

       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 Xen resource using the
       crm(8) shell:

           primitive p_Xen ocf:heartbeat:Xen \
             params \
               xmfile=string \
             meta allow-migrate="true" \
             op monitor depth="0" timeout="30" interval="10"
