AVG Business Cloud Console

The AVG Business Management Consoles come equipped with the functionality of device cloning/device mirroring. When cloning a master hard drive image or VM image with AVG Business ready for a deployment to multiple machines around the network, you will need to carry out the following tasks on the master hard drive that you will be cloning.

In cases where the clones will have the same BIOS serial number, please use the steps in this article to ensure the devices are correctly identified.

On Master Hard Drive Image or VM Image

Install the AVG Business agent on the master device/VM
Turn off the device, snapshot it, then turn it back on
Disconnect the device from your network
Change the device’s name
Open CMD as an administrator and enter the following command:
- For 64 Bit OS: C:\Program Files (x86)\AVG\Business Agent\setup.exe -c
- For 32 Bit OS: C:\Program Files\AVG\Business Agent\setup.exe -c
Open RegEdit and check the Clone value: HKEY_LOCAL_MACHINE\SOFTWARE\AVG\Business Agent
- The Clone value will be set to 1
Turn off the device

Booting Clones

Create a clone from the master device
Regenerate a new MAC address for the clone
Revert the master device and turn it on
Connect the master device to your network
Turn on the cloned device
Connect the cloned device to your network

Two devices should appear in the console.

Scripts

These scripts can be applied for all virtualization types, not just Hyper-V, and can repair existing clones.

Displaying BIOS UUID

$VMName = 'vmname'

(Get-CimInstance -Namespace Root\Virtualization\V2 -ClassName Msvm_VirtualSystemSettingData -Filter "ElementName = '$VMName'").BiosGUID

Changing UUID After Reboot

$VMName = 'vmname'

$MSVM = gwmi -Namespace root\virtualization\v2 -Class msvm_computersystem -Filter "ElementName = '$VMName'"

# get current settings object

$MSVMSystemSettings = $null

foreach($SettingsObject in $MSVM.GetRelated('msvm_virtualsystemsettingdata'))

{

$MSVMSystemSettings = [System.Management.ManagementObject]$SettingsObject

}

# assign a new id

$MSVMSystemSettings['BIOSGUID'] = "{$(([System.Guid]::NewGuid()).Guid.ToUpper())}"

$VMMS = gwmi -Namespace root\virtualization\v2 -Class msvm_virtualsystemmanagementservice

# prepare and assign parameters

$ModifySystemSettingsParameters = $VMMS.GetMethodParameters('ModifySystemSettings')

$ModifySystemSettingsParameters['SystemSettings'] = $MSVMSystemSettings.GetText([System.Management.TextFormat]::CimDtd20)

# invoke modification

$VMMS.InvokeMethod('ModifySystemSettings', $ModifySystemSettingsParameters, $null)
