Serhat AKINCI, a Hyper-V MVP, has just posted this very useful script:
In his own words:
It can be difficult to monitor and assess resources in large Hyper-V environments. This PowerShell based script helps you to understand virtualization inventory, capacity and general resource availability in your Standalone or Clustered Hyper-V Environment.
- More than 2600+ lines of PowerShell, HTML and CSS code examples.
- Creates a plain but detailed and user-friendly HTML report which is compatible with all modern browsers.
- Provides more detailed information via tooltips in the HTML report. (cells with asterisks and highlights)
- Checks and installs required runtime environment prerequisites like Hyper-V and Clustering PowerShell.
- Collects information by using standard Hyper-V and Clustering PowerShell cmdlets and custom WMI queries.
- Shows alerts in the report for certain situations (utilizations, VM checkpoints, replication status, etc.)
- Can be used directly from command-line or as a scheduled Windows task.
- Supports report delivery via e-mail with advanced options. (authentication, TLS/SSL, multiple recipients)
- Includes a mode that reports only alerts in the Hyper-V environment. (aka Highlights Only mode)
- Advanced error handling and logging. (Console messages and log file)

Installation and Deployment
- Boot from SAN. vSphere 4.1 enables ESXi boot from SAN (BFN). iSCSI, FCoE, and Fibre Channel boot are supported. Refer to the Hardware Compatibility Guide for the latest list of NICs and Converged Adapters that are supported with iSCSI boot. See the iSCSI SAN Configuration Guide and the Fibre Channel SAN Configuration Guide.
- Hardware Acceleration with vStorage APIs for Array Integration (VAAI). ESX can offload specific storage operations to compliant storage hardware. With storage hardware assistance, ESX performs these operations faster and consumes less CPU, memory, and storage fabric bandwidth. See the ESX Configuration Guide and the ESXi Configuration Guide.
- Storage Performance Statistics. vSphere 4.1 offers enhanced visibility into storage throughput and latency of hosts and virtual machines, and aids in troubleshooting storage performance issues. NFS statistics are now available in vCenter Server performance charts, as well as esxtop. New VMDK and datastore statistics are included. All statistics are available through the vSphere SDK. See the vSphere Datacenter Administration Guide.
- Storage I/O Control. This feature provides quality-of-service capabilities for storage I/O in the form of I/O shares and limits that are enforced across all virtual machines accessing a datastore, regardless of which host they are running on. Using Storage I/O Control, vSphere administrators can ensure that the most important virtual machines get adequate I/O resources even in times of congestion. See the vSphere Resource Management Guide.
- iSCSI Hardware Offloads. vSphere 4.1 enables 10Gb iSCSI hardware offloads (Broadcom 57711) and 1Gb iSCSI hardware offloads (Broadcom 5709). See the ESX Configuration Guide, the ESXi Configuration Guide, and the iSCSI SAN Configuration Guide.
- NFS Performance Enhancements. Networking performance for NFS has been optimized to improve throughput and reduce CPU usage. See the ESX Configuration Guide and the ESXi Configuration Guide.
- Windows Failover Clustering with VMware HA. Clustered Virtual Machines that utilize Windows Failover Clustering/Microsoft Cluster Service are now fully supported in conjunction with VMware HA. See Setup for Failover Clustering and Microsoft Cluster Service.
- VMware HA Scalability Improvements. VMware HA has the same limits for virtual machines per host, hosts per cluster, and virtual machines per cluster as vSphere. See Configuration Maximums for VMware vSphere 4.1 for details about the limitations for this release.
- VMware HA Healthcheck and Operational Status. The VMware HA dashboard in the vSphere Client provides a new detailed window called Cluster Operational Status. This window displays more information about the current VMware HA operational status, including the specific status and errors for each host in the VMware HA cluster. See the vSphere Availability Guide.
- VMware Fault Tolerance (FT) Enhancements. vSphere 4.1 introduces an FT-specific versioning-control mechanism that allows the Primary and Secondary VMs to run on FT-compatible hosts at different but compatible patch levels. vSphere 4.1 differentiates between events that are logged for a Primary VM and those that are logged for its Secondary VM, and reports why a host might not support FT. In addition, you can disable VMware HA when FT-enabled virtual machines are deployed in a cluster, allowing for cluster maintenance operations without turning off FT. See the vSphere Availability Guide.
- DRS Interoperability for VMware HA and Fault Tolerance (FT). FT-enabled virtual machines can take advantage of DRS functionality for load balancing and initial placement. In addition, VMware HA and DRS are tightly integrated, which allows VMware HA to restart virtual machines in more situations. See the vSphere Availability Guide.
- Enhanced Network Logging Performance. Fault Tolerance (FT) network logging performance allows improved throughput and reduced CPU usage. In addition, you can use vmxnet3 vNICs in FT-enabled virtual machines. See the vSphere Availability Guide.
- Concurrent VMware Data Recovery Sessions. vSphere 4.1 provides the ability to concurrently manage multiple VMware Data Recovery appliances. See the VMware Data Recovery Administration Guide.
- vStorage APIs for Data Protection (VADP) Enhancements. VADP now offers VSS quiescing support for Windows Server 2008 and Windows Server 2008 R2 servers. This enables application-consistent backup and restore operations for Windows Server 2008 and Windows Server 2008 R2 applications.
- vCLI Enhancements. vCLI adds options for SCSI, VAAI, network, and virtual machine control, including the ability to terminate an unresponsive virtual machine. In addition, vSphere 4.1 provides controls that allow you to log vCLI activity. See the vSphere Command-Line Interface Installation and Scripting Guide and the vSphere Command-Line Interface Reference.
- Lockdown Mode Enhancements. VMware ESXi 4.1 lockdown mode allows the administrator to tightly restrict access to the ESXi Direct Console User Interface (DCUI) and Tech Support Mode (TSM). When lockdown mode is enabled, DCUI access is restricted to the root user, while access to Tech Support Mode is completely disabled for all users. With lockdown mode enabled, access to the host for management or monitoring using CIM is possible only through vCenter Server. Direct access to the host using the vSphere Client is not permitted. See the ESXi Configuration Guide.
- Access Virtual Machine Serial Ports Over the Network. You can redirect virtual machine serial ports over a standard network link in vSphere 4.1. This enables solutions such as third-party virtual serial port concentrators for virtual machine serial console management or monitoring. See the vSphere Virtual Machine Administration Guide.
- vCenter Converter Hyper-V Import. vCenter Converter allows users to point to a Hyper-V machine. Converter displays the virtual machines running on the Hyper-V system, and users can select a powered-off virtual machine to import to a VMware destination. See the vCenter Converter Installation and Administration Guide.
- Enhancements to Host Profiles. You can use Host Profiles to roll out administrator password changes in vSphere 4.1. Enhancements also include improved Cisco Nexus 1000V support and PCI device ordering configuration. See the ESX Configuration Guide and the ESXi Configuration Guide.
- Unattended Authentication in vSphere Management Assistant (vMA). vMA 4.1 offers improved authentication capability, including integration with Active Directory and commands to configure the connection. See VMware vSphere Management Assistant.
- Updated Deployment Environment in vSphere Management Assistant (vMA). The updated deployment environment in vMA 4.1 is fully compatible with vMA 4.0. A significant change is the transition from RHEL to CentOS. See VMware vSphere Management Assistant.
- vCenter Orchestrator 64-bit Support. vCenter Orchestrator 4.1 provides a client and server for 64-bit installations, with an optional 32-bit client. The performance of the Orchestrator server on 64-bit installations is greatly enhanced, as compared to running the server on a 32-bit machine. See the vCenter Orchestrator Installation and Configuration Guide.
- Improved Support for Handling Recalled Patches in vCenter Update Manager. Update Manager 4.1 immediately sends critical notifications about recalled ESX and related patches. In addition, Update Manager prevents you from installing a recalled patch that you might have already downloaded. This feature also helps you identify hosts where recalled patches might already be installed. See the vCenter Update Manager Installation and Administration Guide.
- License Reporting Manager. The License Reporting Manager provides a centralized interface for all license keys for vSphere 4.1 products in a virtual IT infrastructure and their respective usage. You can view and generate reports on license keys and usage for different time periods with the License Reporting Manager. A historical record of the utilization per license key is maintained in the vCenter Server database. See the vSphere Datacenter Administration Guide.
- Power Management Improvements. ESX 4.1 takes advantage of deep sleep states to further reduce power consumption during idle periods. The vSphere Client has a simple user interface that allows you to choose one of four host power management policies. In addition, you can view the history of host power consumption and power cap information on the vSphere Client Performance tab on newer platforms with integrated power meters. See the vSphere Datacenter Administration Guide.
- vCenter Update Manager Support for Provisioning, Patching, and Upgrading EMC’s ESX PowerPath Module. vCenter Update Manager can provision, patch, and upgrade third-party modules that you can install on ESX, such as EMC’s PowerPath multipathing software. Using the capability of Update Manager to set policies using the Baseline construct and the comprehensive Compliance Dashboard, you can simplify provisioning, patching, and upgrade of the PowerPath module at scale. See the vCenter Update Manager Installation and Administration Guide.
- User-configurable Number of Virtual CPUs per Virtual Socket. You can configure virtual machines to have multiple virtual CPUs reside in a single virtual socket, with each virtual CPU appearing to the guest operating system as a single core. Previously, virtual machines were restricted to having only one virtual CPU per virtual socket. See the vSphere Virtual Machine Administration Guide.
- Expanded List of Supported Processors. The list of supported processors has been expanded for ESX 4.1. To determine which processors are compatible with this release, use the Hardware Compatibility Guide. Among the supported processors is the Intel Xeon 7500 Series processor, code-named Nehalem-EX (up to 8 sockets).
