Domain Name System (DNS) is an essential part of any network. Berkeley Internet Name Domain (BIND) may be installed and configured on Linux CentOS and provide DNS name resolution. The configuration of BIND includes zone files. Below you will find a sample zone file for the domain name example.com. You may use this sample as a template and input the DNS records for your corresponding domain name.

Microsoft Hyper-V – Create a Virtual Switch using a PowerShell Script
Microsoft Hyper-V allows you to create (3) types of virtual switches (External, Internal and Private). These virtual switches may be created manually using the Hyper-V Manager or you may use a PowerShell (.ps1) script to automate the process. Below you will find a script to create an External virtual switch.
1. Issue the Get-NetAdapter command to provide a list of physical network interface (NIC) card(s) on the host. Take note of the name of the NIC that will be used for the external virtual switch.
2. You may modify the script below to create an external virtual switch.
3. Run Microsoft Powershell (as an Administrator) to create the external virtual switch.
4. Lastly, verify the creation of the virtual switch using the Hyper-V Manager > Virtual Switch Manager.
Microsoft Hyper-V – Install Hyper-V and the Management Tools using PowerShell
Microsoft allows you to install the Hyper-V role using PowerShell (run as an administrator) as well as the graphical user interface (GUI). One of the advantages of using PowerShell is that you can create a script to deploy a large number of Hyper-V hosts. During my initial testing I was able to install the Hyper-V role but the Management Tools were not being installed. The PowerShell installation requires the -IncludeManagementTools parameter to install the Management Tools.
The command to install both the Hyper-V role and the Management Tools is as follows:
Install-WindowsFeature –Name Hyper-V -ComputerName <computer_name> -IncludeManagementTools -Restart
If you will be installing the Hyper-V role on the local host then remove the -ComputerName <computer_name> parameter.
Microsoft provides great documentation for their solutions and the Install the Hyper-V Role and Configure a Virtual Machine document is no exception.
