Failed Live Migrations Block Upgrades by Default
When you upgrade to v1.9.1 or later, Harvester does not shut down a virtual machine if its live migration fails during the pre-drain phase of a node upgrade. The virtual machine keeps running, and the upgrade waits while the migration is retried.
The upgrade remains blocked until the live migration succeeds or the virtual machine is stopped. No timeout applies. For more information, see Unblocking a Waiting Upgrade.
To have Harvester shut down these virtual machines instead, set the shutdownVMOnMigrationFailure field of the upgrade-config setting to true before starting the upgrade. The virtual machines remain stopped after the upgrade, and you must start them manually. For more information, see Keeping the Automatic Shutdown Behavior.
