Overview<\/strong><\/h1>\n

When your network environment reaches the point where it can become complicated to manage your virtual machines, you can use PowerShell Direct to eliminate all the network constraints. PowerShell Direct lets you to manage your VMs whether or not you have network connectivity, just as long as your virtual machines are located on your Hyper-V host!<\/p>\n

Introduction<\/h1>\n

Many of you have probably already experienced the awful moment when you modify a network setting on a virtual machine (VM) and suddenly all connectivity is lost to the VM. Up to now, you would then need to use the Hyper-V console to retrieve the VM. Now, with PowerShell Direct, this is no longer necessary. PowerShell allows you to access the virtual machine directly without using the network. This happened because Microsoft introduced a new feature called “PowerShell Direct<\/strong>“. As the name implies, PowerShell is now able to directly access the virtual machine. How? It does it by using the Virtual Machine Bus (VMBus).<\/p>\n

Here is the official definition of Microsoft:<\/p>\n

VMBus<\/strong> \u2013 Channel-based communication mechanism used for inter-partition communication and device enumeration on systems with multiple active virtualized partitions. The VMBus is installed with Hyper-V Integration Services.<\/p>\n<\/blockquote>\n

PowerShell Direct<\/strong><\/h2>\n

Since Windows PowerShell version 5, Microsoft has implemented a new way to directly manage your virtual machines without network connectivity. However, this new feature requires some prerequisites before it can be used:<\/p>\n
