= Configuring a VM eviction strategy using the CLI
|
|
|
|
[role="_abstract"]
|
|
You can configure an eviction strategy for a virtual machine (VM) by using the command line.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
The default eviction strategy is `LiveMigrate`. A non-migratable VM with a `LiveMigrate` eviction strategy might prevent nodes from draining or block an infrastructure upgrade because the VM is not evicted from the node. This situation causes a migration to remain in a `Pending` or `Scheduling` state unless you shut down the VM manually.
|
|
|
|
You must set the eviction strategy of non-migratable VMs to `LiveMigrateIfPossible`, which does not block an upgrade, or to `None`, for VMs that should not be migrated.
