UPDATE 2016-12-28: Updated for latest Vyos 1.1.7 and again a view little script tweaks. I play a lot with VMs and I wanted a small virtual router to allow internet access for my Labs. After some searching I found Vyos and created a few scripts to automate the router installation. The result will be a router only consuming 256MB and offering DNS, DHCP and NAT to 5 different subnets. If you want you can extend or change the subnets as much as you want. These are the steps I followed: Download Vyos: http://packages.vyos.net/iso/release/1.1.7/vyos-1.1.7-amd64.iso and put it in D:\ISO. If you put ISO somewhere else, change the location in the script. Open Powershell ISE as Administrator and ...

If you want to install Hyper-V on a Virtual Machine the following error message will appear: ” Hyper-V cannot be installed: A Hypervisor is already running”. But it’s possible with PowerShell although you will not be able to run a virtual machine in the virtual machine. Open a PowerShell console as administrator in the virtual machine where you want Hyper-V installed. Type te following commands: Set-ExecutionPolicy RemoteSigned Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart Install-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature Restart-Computer Now Hyper-V is installed for testing purposes, but running a Virtual Machine in a Virtual Machine will not be possible.

I have a server where I create a certain type of files that I have to send by email on a daily basis to the same email receiver. Sending an email with Powershell is not complicated, just use Send-MailMessage. But since I had to do this a lot, I decided to create a function to do this job including a search window to find and attach the file. I added the following function to my PowerShell profile: #Send email with Attachment(s) Function Send-CustomMailMessage { [System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms") | Out-Null $FileLocation = New-Object System.Windows.Forms.OpenFileDialog $FileLocation.initialDirectory = 'd:\' #Or any other location $FileLocation.Multiselect = $true $Dialog = $FileLocation.ShowDialog() If ($Dialog -eq 'Cancel') { Return #End Function ...

UPDATE 20131028: Added snap-in registration I thought it would be nice to share my PowerShell profile settings as a starter for new users. It’s rather basic, I only added a few things to make my PowerShell console ready from the start. But first some easy tips to check and if needed create a profile. Test if you have a PowerShell Profile. Start Powershell and type: Test-Path $PROFILE If the result is “False” you don’t have a PowerShell profile. Let’s create one: New-Item -Path $PROFILE -Type File -Force This will create an empty profile. Now we can edit the profile file: Notepad $PROFILE In this profile I’ve put in the following things: ...

Windows Server 2012 – Create network settings for Hyper-V cluster with Powershell

Oct

2012

Windows 2012 has some great new network features that makes network usage much more efficient. Till Windows 2012 it was necessary to use dedicated NICs for certain network traffic (Cluster, Storage). But with Windows 2012 we can virtualize the network by creating NIC Teams and Extensible Switches and Virtual Adapters. So when you are building a Hyper-V cluster, it’s not necessary anymore to load a lot of NICs in a server. Instead we create a NIC Team that bundles all the available Network NICs (whatever hardware mix, doesn’t matter), create a Virtual Switch and then Virtual Adapters. To make it more easy Aiden Finn created a PowerShell script that does ...
