Read guest variables from a VM

The variable location will depend on the method of guest setup that you are using for your VM. Here are some general guidelines.

Cloud	Method	Variable location
Private	Cloud-init	The variables are stored on the cloud-init ISO, which has the label "config-2". The variables file is "openstack/latest/vm-variables.rc"
Private	Hypervisor tools	On ESXi, run the following command in the guest to get the value of a variable: vmtoolsd --cmd "info-get guestinfo.abiquo.<variable-name>"
Private	Hypervisor tools	For vCloud Director, hypervisor tools does not support variables
Public	Cloud-init	The variables are stored in the /opt/abiquo-env.rc file
Amazon	Cloudbase-init ec2launchv2 ec2lanch ec2config	On Windows, the variables are stored in the C:\ProgramData\Abiquo\abiquo-env.rc file
Azure	Cloud-init	On Windows, according to the Azure documentation on custom data Custom data is placed in %SYSTEMDRIVE%\AzureData\CustomData.bin as a binary file, but it is not processed. If you wish to process this file, you will need to build a custom image, and write code to process the CustomData.bin.. On Linux, you can use cloud-init to read the variables from custom data.
