This chapter explains the various networking settings in more detail.Creating virtual machines by importing disk images using the web console. You can configure all eight network cards on the command line using VBoxManage modifyvm.See Section 8.8, VBoxManage modifyvm. Four of the network cards can be configured in the Network section of the Settings dialog in the graphical user interface of Oracle VM VirtualBox.

Which vSwitch types are in Hyper-V and what are their differences?Figure 6.34 Confi guring the VHD The VHD will be created when you click Finish. This enables Oracle VM VirtualBox to intercept data from the physical network and inject data into it, effectively creating a. This driver is therefore called a net filter driver. With bridged networking, Oracle VM VirtualBox uses a device driver on your host system that filters data from your physical network adapter.

IвЂ™ve got answers! What is Hyper-V Virtual Switch?The Hyper-V vSwitch is a software-defined, layer-2, Ethernet network-traffic switch. How can I configure one VM (virtual machine) to see only the internal network, but not the internet?Did any of these questions ring a bell with you? If so, please keep reading. WhatвЂ™s the PowerShell command to remotely configure vSwitch?

Today, vSwitch is considered to be very solid, but still continues to be improved. Like other Hyper-V features, vSwitch has been improved with every new Hyper-V version. ItвЂ™s available by default within the Hyper-V Manager installation and contains extended capabilities for security and resource tracking.

External vSwitch will link a physical NIC of the Hyper-V host with a virtual one and then give your VMs access outside of the host, meaning your physical network and internet (if your physical network is connected to internet). There are three vSwitch types available: Hyper-V ManagerVirtual Switch Manager helps configure vSwitch and Global Network Settings, which simply lets you change the default MAC address range if you see any reason for that (Note: changing the MAC range wonвЂ™t affect an existing virtual switch)Creation of the virtual switch is just easy as following. To set up a network environment, youвЂ™ll need to select Virtual Switch Manager in the right pane of Hyper-V Manager. If you attempt to create a VM right after the set-up process, you wonвЂ™t be able to connect it to a network. Hyper-V vSwitch setupThere is no pre-configuration of vSwitch during Hyper-V setup.

Disabling this setting will leave your hypervisor OS without network connectivity. The Allow management OS to share this network adapter setting is enabled by default. You can select an appropriate physical NIC if you have a few of them for an external vSwitch. VSwitch Manager Creating an external vSwitch with Hyper-V Virtual Switch ManagerTo create an external vSwitch, a creation wizard allows you to tune a few settings. This will completely isolate the VMs in that sandbox.Figure 2. Private vSwitch will create a virtual network where all connected VMs will see each other, but not the Hyper-V host.

The same is true for the physical environment it allows you to segregate hypervisor traffic by providing separate broadcast domains within the same network.Once you click the Apply button, be prepared to lose physical connectivity for a moment while Hyper-V needs to turn the physical NIC off, configure the vSwitch and turn both on: Figure 4. VLAN ID: This setting enables Virtual LAN (VLAN) for the management OS. Make sure you know what youвЂ™re doing in advance here.NOTE: You wonвЂ™t be able to enable SR-IOV to an existing vSwitch. There are a few requirements to keep in mind such as BIOS compatibility, SLAT support by your CP and a SR-IOV PCIe network card in your system. An overview of enabling SR-IOV can be found here. SR-IOV (Single Root I/O Virtualization) allows you to prepare such configuration that you can increase network throughput by bypassing a vSwitch and redirecting traffic directly to the VM.

Configure the static IP address and subnet mask manually:Figure 7. Go to hypervisor OS Network Connections and find the connection related to your internal vSwitch. If there is no DHCP server, perform some post-configuration for VMs connected to a private vSwitch: New VM creation wizardHINT: Check which vSwitch of all your VM are connected to by using:Get-VMNetworkAdapter -VMName * VM network connectivityBe informed, that VM connected to an internal vSwitch or private vSwitch will get IP address automatically if only DHCP server is present at the same virtual network. While the full syntax needs to be checked on TechNet, a few examples of PS scripts are below.HINT: DonвЂ™t forget to run the PowerShell console with elevated permissions.Following command to create an external vSwitch for вЂњEthernetвЂќ NIC:New-VMSwitch -Name 'External vSwitch' -NetAdapterName 'Ethernet' -AllowManagementOS 1 -Notes 'PowerShell example of External vSwitch creation'Next command to create an internal vSwitch:New-VMSwitch -Name 'Internal vSwitch' -SwitchType 'Internal' -Notes 'PowerShell example of Internal vSwitch creation'The type of vSwitch is defined by using вЂњ-SwitchType вЂњInternal/PrivateвЂќ parameter or any of following for an external vSwitch вЂњ-NetAdapterName вЂњname of the physical NICвЂќ / -NetAdapterInterfaceDescription вЂњdescription of a physical NICвЂќвЂќ.Once the vSwitches are created, you can use them while configuring your VMвЂ™s network connectivity. Internal vSwitch creationNOTE: Just like any other administrative operation in Windows 2012 R2, this can be automated by a PowerShell script.

IвЂ™ll be sharing some more useful Hyper-V-related material soon. Checking network connectivity within an internal switchTo configure a private vSwitch, use static IPs for all VMs and place them on the same subnet.ThatвЂ™s it, folks. Once you apply the right settings, youвЂ™ll be able to ping the hypervisor to check and see if everything has been set up correctly.Figure 8. Turn on the VM and provide the VM NIC with an appropriate static IP from the same subnet to setup a network connection.
