This is because VMs with attached GPUs\ncan't be\n[live migrated](/compute/docs/instances/live-migration-process#limitations).\n\nYou must set these VMs to\n[stop for host maintenance events](/compute/docs/instances/host-maintenance-overview#terminate_and_optionally_restart).\nYou can set your stopped VMs to\n[automatically restart](/compute/docs/instances/host-maintenance-overview#autorestart)\nafter the maintenance event completes.\n| **Warning:** For VMs with GPUs, data on any Local SSD disks attached to the VM is unrecoverable if Compute Engine restarts the VM for [host maintenance events](/compute/docs/gpus/gpu-host-maintenance).\n\nHost maintenance events typically occur once every two weeks, but might occasionally run more frequently.\n\nThis document discusses how you can minimize disruptions to your workloads during a maintenance event.\n| **Note:** VMs with attached GPUs can take up to one hour to terminate after failures or [host errors](/compute/docs/faq#hosterror).\n\nReceive advance notice before maintenance events\n------------------------------------------------\n\nYou can\nmonitor the maintenance schedule for your virtual machine (VM) instance, and\nprepare your workloads to transition through the system restart.\n\nTo receive advance notice of host events, monitor the\n`/computeMetadata/v1/instance/maintenance-event` metadata value.\nIf the request to the metadata server returns `NONE`, then the VM isn't\nscheduled to stop. For example, run the following command from within a VM: \n\n```\ncurl http://metadata.google.internal/computeMetadata/v1/instance/maintenance-event -H \"Metadata-Flavor: Google\"\n\nNONE\n```\n\nIf the metadata server returns `TERMINATE_ON_HOST_MAINTENANCE`, then your\nVM is scheduled for stopping. Compute Engine gives GPU\nVMs a 1-hour stopping notice, while normal VMs receive only\na 60-second notice. Configure your application to transition through the\nmaintenance event. For example, you might use one of the following techniques:\n\n- Configure your application to temporarily move work in progress to a\n [Cloud Storage bucket](/storage/docs/uploading-objects), then retrieve\n that data after the VM restarts.\n\n- Write data to a\n [secondary Persistent Disk](/compute/docs/disks/add-persistent-disk).\n When the VM automatically restarts, the Persistent Disk can be\n reattached and your application can resume work.\n\nWhat's next?\n------------\n\n- Learn more about [GPU platforms](/compute/docs/gpus).\n- To learn more about managing and scaling groups of VMs, see [Set the group's target size](/compute/docs/instance-groups/add-remove-vms-in-mig#set_the_groups_target_size).\n- To monitor GPU performance, see [Monitoring GPU performance](/compute/docs/gpus/monitor-gpus).\n- To improve network performance, see [Use higher network bandwidth](/compute/docs/gpus/optimize-gpus).\n- Learn how to [troubleshoot VM shutdowns and reboots](/compute/docs/troubleshooting/troubleshooting-reboots)."]]
