Some time ago I wrote a blog post PowerShell oneliner to enable VM Network Optimization in VMM
Last week I received a question about this post: Howto accomplish this on only VM’s on a specific cluster, or even a specific node.
So let’s start with the node since that’s the easy one.
To select all virtual machines on a node:
|
1 |
Get-VMHost -ComputerName HVC01N01 | Get-VM |
And to enable the VM Network Optimzation on them:
|
1 |
Get-VMHost -ComputerName HVC01N01 | Get-VM | ForEach-Object { Set-VirtualNetworkAdapter -VMNetworkOptimizationEnabled $True } |
But most clusters will consist of more than one node…
Executing a line for each cluster node? Well… there should be a more elegant way to accomplish that task.
And there is 😉
To select the cluster:
|
1 |
Get-VMHostCluster -Name HVC01 |
To select all nodes within that cluster:
|
1 |
Get-VMHostCluster -Name HVC01 | Get-VMHost |
To select all VMs on a cluster:
|
1 |
Get-VMHostCluster -Name HVC01 | Get-VMHost | Get-VM |
And of course to set the VM Network Optimization on all those VM’s:
|
1 |
Get-VMHostCluster -Name HVC01 | Get-VMHost | Get-VM | ForEach-Object { Set-VirtualNetworkAdapter -VMNetworkOptimizationEnabled $True } |
Note how easy you can use the pipeline this way in order to go deeper from cluster to nodes to VM’s 🙂
