What disk considerations are taken for VM migration during Host Maintenance in GCE?

There are no persistent disk considerations that you manage. Storage is not located on the hypervisor host. Migrations do not involve storage (snapshots, moving, restoring, etc.).

When Google performs a maintenance event, there are two major types: Host Maintenance and Lightweight.

Host maintenance performs kernel upgrades, hardware repair, etc on the machine running the hypervisor. Google uses live migration to move your VM to another hypervisor.

Lightweight performs hypervisor level upgrades, networking stack updates, etc. This does not require live migration.

Note: Live Migration does not take down your VM. This process should be transparent to your VM applications. If you are experiencing issues, open an issue tracker:
