Hi there,
when you retrieve the guest network interface with get-vmguestnetworkinterface then everything is written in this object:
VMId
VM
NetworkAdapter
SubnetMask
NicId
NetworkAdapterId
Name
IPPolicy
Ip
Dns
DefaultGateway
Description
Mac
RouteInterfaceId
Uid
DnsPolicy
WinsPolicy
Wins
Those are properties of the guest network interface. As you can see it holds information frim which VM this interface comes.
when you do:
get-vm my_vm_name|Get-VMGuestNetworkInterface |?{$_.name -eq "Local Area connection"}
The you will receive this object , the guest netowwork interface object,. It will show the vmid,vm name etc... in its properties
for example do this
$nic=get-vm my_vm_name|Get-VMGuestNetworkInterface |?{$_.name -eq "Local Area connection"}
then
$nic | format-list *
You will be surprised by how much info this object holds.
All this infromation is passsed then to the set-vmguestnetworkinterface
This cmdlet EXPECTS to see on the input this kind of object , a guest network interface object:
-VmGuestNetworkInterface <VMGuestNetworkInterface[]>
Specify the guest network interface you want to configure.
Required? true
Position? named
Default value
Accept pipeline input? true (ByValue)
Accept wildcard characters? true
Since it expects that kind of object you have to deliver it this. So best way to deliver that is to grab that network interface object that you want to change by using: get-vmguestnetworkinterface
This describes that it is mandatory to provide this object. Since it accepts value from pipeline you can do
get the desired interface | set-the desired interface
The error you are receiving is correct because you lost 2 parameters in the command line such as:
C:\PS>Set-VMGuestNetworkInterface -VMGuestNetworkInterface $vmGuestNetworkInterface -HostUser Admin -HostPassword Pass01 -GuestUser User -GuestPassword Pass02 -Netmask 255.255.255.255 -Gateway 10.23.112.58
If you put there the : root and root password from the esx it will work or the VC creds, as per manual
-HostUser <String>
Specify the user name you want to use for authenticating with the host. You need to specify host credentials only if the version of the vCenter Server or ESX you are authe
nticating with is earlier than 4.0, or the VIX version you have installed is earlier than 1.10.
You can also build yourself a credential object because this command supports it
-GuestCredential <PSCredential>
Specify a PSCredential object that contains credentials for authenticating with the guest OS. Do not use this parameter if the -GuestUser and -GuestPassword parameters are
used.
-HostCredential <PSCredential>
Specify a PSCredential object that contains credentials for authenticating with the host. Do not use this parameter if the -HostUser and -HostPassword parameters are used.
You need to specify host credentials only if the version of the vCenter Server or ESX you are authenticating with is earlier than 4.0, or the VIX version you have install
ed is earlier than 1.10.
$guestcred=get-credential
$hostcred=get-credential
Put proper credentials for the guest OS, and the for host
then
Set-VMGuestNetworkInterface -VMGuestNetworkInterface $vmGuestNetworkInterface -HostCredential $hostcred -GuestCredential $guestcred -Netmask 255.255 .255.255 -Gateway 10.23.112.58
Then it will work, assuing you have your guest network inferface stored in $vmGuestNetworkInterface
In my opinion the easiest way is to send that info via the pipeline
so
get-vm "your_VM"|Get-VMGuestNetworkInterface -hostcredential $hostcred -guestcredential $guestcred|?{$_.name -eq "Local Area connection"} | set-vmguestnetworkinterface -hostcredential $hostcred -guestcredential $guestcred -Netmask 255.255.0.0 -Gateway New.IP.ADD.RES
For example 
by the way
===========
Do I have to run the whole thing as one command? e.g.
$nic=Get-VMGuestNetworkInterface -VM as01.pool.local -GuestUser user1 -GuestPassword password | ? {$_.name -eq "Local Area Connection"} | Set-VMGuestNetworkInterface -VMGuestNetworkInterface $nic -Guest User user1 -GuestPassword password -Ip 10.1.80.99 -Netmask 255.255.255.0 -Gateway 10.1.80.111
=========
This is not correct
That should be 2 lines
if you use additional variable to hold the guestnic
$nic=Get-VMGuestNetworkInterface -VM as01.pool.local -GuestUser user1 -GuestPassword password | ? {$_.name -eq "Local Area Connection"}
That was 1 line to assign variable $nic to a guestnetworkinterface object
Set-VMGuestNetworkInterface -VMGuestNetworkInterface $nic -Guest User user1 -GuestPassword password -Ip 10.1.80.99 -Netmask 255.255.255.0 -Gateway 10.1.80.111
And that was second line which uses the $nic variable that you have filled previously with that object.
if you want to use 1 line do not use the $nic var , but put everything through the pipeline
get-vm "your_VM"|Get-VMGuestNetworkInterface -hostcredential $hostcred -guestcredential $guestcred|?{$_.name -eq "Local Area connection"} | set-vmguestnetworkinterface -hostcredential $hostcred -guestcredential $guestcred -Netmask 255.255.0.0 -Gateway New.IP.ADD.RES
This was 1 long line using the hostcredential and guestcredential PScredential objects in order to authorize on host and in guest.
======
Even then set-vmguestnetworkintererface is not being told which VM to modify....?
======
set-vmguestnetworkinterface IS told which vm's network interface it needs modify , By passing the CORRECT interface to it.
and when you are getting the interface , then get only the desired interface , from desired vm, correct ?
Then again this object also has INSIDE of it, information to which vm it is related to.
Please let me know if you need any other explanation
