A VMM-managed fabric server comprises the following workloads: Hyper-V hosts and host clusters, VMM library servers, Pre-boot eXecution Environment (PXE), the Windows Server Update Management (WSUS) server, and the VMM management server; refer to the following diagram:
You can monitor the update status of the servers, scan for compliance, and update all or a set of the servers' resources as well as exempt resources from the installation of an update.
You can also orchestrate an update remediation on Hyper-V host clusters, where VMM will place one node of the cluster at a time in maintenance mode and install the updates. If the cluster supports live migration, the Intelligent Placement feature will be used to live-migrate the VMs off the node; otherwise, VMM will save the state for the VMs, and the host will start the VM after updating it.
