VM Migration
Mapping
Specifies an alternate interface for migration. You can specify this when, for
example, the network address used for virtual machine migration on a node
differs from the address of the node used for cluster communication.
Specifying the following indicates that when you migrate a virtual machine from
member to member2, you actually migrate to target2. Similarly, when you
migrate from member2 to member, you migrate using target.
member:target,member2:target2
Migration type Specifies a migration type of
live
or
pause
. The default setting is
live
.
Hypervisor Hypervisor URI (automatic, KVM, or Xen)
Automatically
start this
service
If enabled, this virtual machine is started automatically after the cluster forms a
quorum. If this parameter is disabled, this virtual machine service is not started
automatically after the cluster forms a quorum; the virtual machine is put into the
disabled
state.
Run exclusive If enabled, this virtual machine can only be relocated to run on another node
exclusively; that is, to run on a node that has no other virtual machines running
on it. If no nodes are available for a virtual machine to run exclusively, the virtual
machine is not restarted after a failure. Additionally, other virtual machines do not
automatically relocate to a node running this virtual machine as
Run
exclusive
. You can override this option by manual start or relocate operations.
Failover
Domain
Defines lists of cluster members to try in the event that a virtual machine fails.
Recovery
policy
Recovery policy provides the following options:
Disable — Disables the virtual machine if it fails.
Relocate — Tries to restart the virtual machine in another node; that is, it
does not try to restart in the current node.
Restart — Tries to restart the virtual machine locally (in the current node)
before trying to relocate (default) to virtual machine to another node.
Restart-Disable — (Red Hat Enterprise Linux Release 5.6 and later) The
service will be restarted in place if it fails. However, if restarting the service fails
the service will be disabled instead of being moved to another host in the
cluster.
Maximum
number of
restart failures
before
relocating
Maximum number of restarts for an independent subtree before giving up.
Length of time
in seconds
after which to
forget a restart
Amount of time before a failure is forgotten for an independent subtree.
