In hyper-v, which generation is needed to use secure boot or scsi virtual hard disk?
The Hyper-V role in Windows Server lets you create a virtualized computing environment to create and manage virtual machines. You can run multiple operating systems on one physical computer and isolate the operating systems from each other. With this technology, you can improve the effectiveness of your computing resources.

Advantages with Hyper-V
Hyper-V Availability & Install Using Server ManagerHyper-V is available from Windows Server 2008 onwards as an inbuilt server role for x64 versions.
Other Operating Systems Support on Hyper-V VMsHyper-V supports both emulated and Hyper-V-specific devices for Linux and FreeBSD virtual machines. When running with emulated devices, no additional software is required. However, emulated devices do not provide high performance and cannot leverage the Hyper-V technology. To make full use of all benefits that Hyper-V provides, best to use Hyper-V-specific devices for Linux and FreeBSD. The drivers required to run Hyper-V-specific VMs are known as Linux Integration Services (LIS) or FreeBSD Integration Services (BIS). Hyper-V Virtual SwitchHyper-V Virtual Switch is a software-based layer-2 Ethernet network switch available in Hyper-V Manager when you install the Hyper-V role. Types Hyper-V Virtual Switches

Hyper-V VM GenerationsThere are currently two generations of Hyper-V virtual machines, Gen1 & Gen2. In general, the choice between these two generations depends on many factors like the OS of the guest operating system, the OS of the host operating system, boot methods, etc. Below are the significant differences on both generations: BiosThis software is responsible for start-up and hardware configuration.

Hardware Limits of Gen1 VMs
VM BootThe boot time of Gen2 VM is 20% faster than Gen1 due to the faster start of the UEFI. Installation of a guest operating system also takes up to 50% less time Gen2 Availability on Hyper-VGeneration 2 VMs released by Microsoft with Hyper-V for Windows Server 2012 R2 and Windows 8.1; hence these versions of 64-bit windows are because of UEFI 2.3.1 with Secure Boot support option. Hyper-V Security
Hyper-V ScalabilityHigh Availability for Hyper-VOne way to ensure Hyper-V High Availability is to place guest VMs to cluster nodes (other physical servers). If one of the physical servers fails, another cluster node automatically detects the system failure and starts running the VM. A High Availability Cluster is a group of 2 or more bare metal servers used to host virtual machines. The server nodes (physical machines) work together to provide redundancy and failover to your virtual machines, with minimal downtime on the VMs. A Hyper-V cluster can support up to 64 nodes with a maximum of 8000 VMs. Each node can support a maximum of 1024 VMs. Exactly how many VMs you can get on a node will depend on the resources (CPU and memory) available to the node and how your VMs are configured. If you are creating a failover cluster that includes clustered virtual machines, the cluster servers must support the hardware requirements for the Hyper-V role. Hyper-V requires a 64-bit processor that provides for the following:
Hyper-V High Availability Requirements
Enable the Failover Clustering Role on a Hyper-V Host
Create a Highly Available Hyper-V VMTo make a Hyper-V VM in a failover cluster highly available, create and configure a Hyper-V failover cluster and validate the configuration in the Failover Cluster Manager.
Existing Hyper-V VM Highly Available
System Center Virtual Machine ManagerSystem Center Virtual Machine Manager (SCVMM) is part of Microsoft’s System Center line of virtual machines and Hyper-V hosts management and reporting tools. System Center Virtual Machine Manager enables increased physical server utilization by making fast and straightforward consolidation on virtual infrastructure.
To configure the SCVMM below components are mandatory to manage and administer the Hyper-V virtualization.
Install and Configure System Center Virtual Machine Manager
ClosingDuring setup, VMM enables the following firewall rules. These rules remain in effect even if you later uninstall VMM.
SCVMM toll can add, provision, and manage Hyper-V and VMware virtualization hosts and clusters. In addition, SCVMM can manage VMware ESX servers and its virtual machines in a limited capacity. Does Microsoft HyperHyper-V offers three types of virtual controllers: IDE, SCSI, and Virtual host bus adapters (HBAs).
What generation version should be used to utilize the Secure Boot functionality in HyperSecure Boot is enabled by default for generation 2 virtual machines. If you need to run a guest operating system that's not supported by Secure Boot, you can disable it after the virtual machine's created.
Does HyperNote: We don't require Secure Boot, but if you're using Hyper-V with Device Guard, Credential Guard or other Microsoft features, you'll need this enabled for the features to work correctly. If you are using Hyper-V in isolation, you don't need Secure Boot to be enabled.
What generation virtual machine supports VM Secure Boot?Secure Boot is a feature available with generation 2 virtual machines that helps prevent unauthorized firmware, operating systems, or Unified Extensible Firmware Interface (UEFI) drivers (also known as option ROMs) from running at boot time. Secure Boot is enabled by default.
