If a VM is powered off during a periodic assessment, the VM will be automatically assessed and applicable patches will be installed automatically during the next periodic assessment (usually within a few days) when the VM is powered on.ĭefinition updates and other patches not classified as Critical or Security will not be installed through automatic VM guest patching. The VM must be running during the off-peak hours for patches to be automatically installed. Patches are installed only during off-peak hours for the VM, depending on the time zone of the VM. Patches are installed within 30 days of the monthly patch releases, following availability-first orchestration described below. This automatic assessment ensures that any missing patches are discovered at the earliest possible opportunity. The patches can be installed any day on the VM during off-peak hours for the VM. The VM is assessed periodically every few days and multiple times within any 30-day period to determine the applicable patches for that VM. Patch assessment and installation are automatic, and the process includes rebooting the VM as required. This process kicks off automatically every month when new patches are released.
If automatic VM guest patching is enabled on a VM, then the available Critical and Security patches are downloaded and applied automatically on the VM. How does automatic VM guest patching work? Virtual machine health, as determined through platform health signals, is monitored to detect patching failures.Patch orchestration is managed by Azure and patches are applied following availability-first principles.Patches are applied during off-peak hours in the VM's time zone.
