Script to rename VM with DNS Name listed in VC

[ebuker]

I'm very new to powershell, and I've been trying to figure this out using portions of code I've found, but to no avail.

I'm looking for a script to take the DNS hostname listed in VCenter for a given VM and rename the VM.

Eg.

Host01VM01 (as listed in Vcenter) - DNS name of "something.xyz.com".   Rename VM to "something.xyz.com" in Vcenter.

You can try:

Get-VM | `
Where-Object { $_.Guest.HostName } | `
ForEach-Object { Set-VM -VM $_ -Name $_.Guest.HostName -Confirm:$false }

Thanks for the quick reply.

When I run this I don't get any output, just returns to the powershell command line.  I'm obviously doing something wrong...

Also -  I should have included this in my original post, but I need to rename all the VM's within one cluster in VCenter, leaving the others untouched.

[RvdNieuwendijk · Accepted solution]

To run the script only for a cluster called "MyCluster" you can do:

Get-Cluster "My Cluster" | Get-VM | `
Where-Object { $_.Guest.HostName } | `
ForEach-Object { Set-VM -VM $_ -Name $_.Guest.HostName -Confirm:$false }

This script will only work for VM's that have the VMware Tools installed and probably only for VM's that are powered on.

Works perfectly.  Thanks for your help.
