Hi Guys,

I have a list of virtual machine's IP addresses they are all VMware managed by a vcenter server.

I need to change the ip addresses, Netmask, Gateway, and the port group for every single one.

What is the quickest way of doing this, is there a powercli command I can use?

Thank you all for the support.

You can use the Set-VMGuestNetworkInterface cmdlet to do it.
Check this link the example syntax.

use this script with PowerCLI

Get-VM VMName | Get-VMGuestNetworkInterface -GuestUser Administrator -GuestPassword <password> -HostUser root -HostPassword <password> | Set-VMGuestNetworkInterface -IPPolicy Static -Ip <IPAddress> -Netmask 255.255.252.0 -Gateway <Gateway> -GuestUser Administrator -GuestPassword <password> -HostUser root -HostPassword <password> 

Open in new window


Make sure VMware Tools is installed in the VM.

VMName is the name of the VM in the inventory.

GuestUser and GuestPassword our Guest Userids and Passwords, so if AD, they are AD usernames and passwords to enable login to the VM.

I think IP Address and Gateway address are self-explanatory.

HostUser and Hostpassword are Host usernames and passwords.

@Andrew
The command you gave is to retrieve the information.
Its a GET command. The author of the question is asking how to set these parameters.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

@Abhilash Hb - is it ? did you check all the script?

and then PIPED through a Set-VMGuestNetworkInterface

a working example of code,  see all the code.

Set-VMGuestNetworkInterface

Get-VM VMName | Get-VMGuestNetworkInterface -GuestUser Administrator -GuestPassword <password> -HostUser root -HostPassword <password> | Set-VMGuestNetworkInterface -IPPolicy Static -Ip <IPAddress> -Netmask 255.255.252.0 -Gateway <Gateway> -GuestUser Administrator -GuestPassword <password> -HostUser root -HostPassword <password>

I am going to connect, using vi-connect, to a vcenter server, so I presume I wont need the -HostUser root -HostPassword <password>

Also do we need the  -GuestUser -GuestPassword <password> twice in the pipelines?

I also need to change the port group, how do I add this to the script?

Yes. You can create a input value and input it when it pops up but in this above case yes you will have to do it twice.
Once for Get and once for Set.

If you are connected to vCenter Server, no host options needed.

username and password requried twice for two functions, the first is get the network adaptor, and the second is set the IP address.

virtual machine portgroup I assume?

the code:

Get-VM VMName | Get-VMGuestNetworkInterface -GuestUser Administrator -GuestPassword <password> -HostUser root -HostPassword <password> | Set-VMGuestNetworkInterface -IPPolicy Static -Ip <IPAddress> -Netmask 255.255.252.0 -Gateway <Gateway> -GuestUser Administrator -GuestPassword <password> -HostUser root -HostPassword <password>

Doesn't work, I get this error message below:

I am going to use this script instead:

$wmi = Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"

$wmi.EnableStatic("10.0.0.15", "255.255.255.0")

$wmi.SetGateways("10.0.0.1", 1)

$wmi.SetDNSServerSearchOrder("10.0.0.100")

Open in new window


What does the , 1 mean on the $wmi.SetGateways("10.0.0.1", 1)?

this doesn't work either because of the IP addresses!

for the port group that's the way I've done my script, I didn't want to do the foreeach, however I am having to press enter each time, is there a way around it - not pressing enter to process the next command?
Get-VM DEV-QRE-pro-12  | get-networkadapter | set-networkadapter -networkname "VM_Build_2262" -Confirm:$false

Get-VM DEV-QRE-pro-13  | get-networkadapter | set-networkadapter -networkname "VM_Build_2262" -Confirm:$false
