 - On Windows, JoularJX uses a custom power monitor program that uses the [Windows RAPL driver by Hubblo](https://github.com/hubblo-org/windows-rapl-driver), and therefore require installing the driver first, and runs on Intel or AMD CPUs (since Ryzen).
-- On Windows, to read the data from the RAPL driver, we use a custom program monitor called [Power Monitor for Windows](https://github.com/joular/WinPowerMonitor). It used to be part of JoularJX, but now is in its own repository. Download the binary (or compile the source code), and specify its path in ```config.properties```.

 - On macOS, JoularJX uses `powermetrics`, a tool bundled with macOS which requires running with `sudo` access. It is recommended to authorize the current users to run `/usr/bin/powermetrics` without requiring a password by making the proper modification to the `sudoers` file.
 - On Raspberry Pi devices on GNU/Linux, JoularJX uses our own research-based regression models to estimate CPU power consumption with support for the following device models (we support all revisions of each model lineup. However, the model is generated and trained on a specific revision, listed between brackets, and the accuracy is best on this particular revision):

@@ -98,10 +100,17 @@ JoularJX can be configured by modifying the ```config.properties``` files:
 - ```save-call-trees-runtime-data```: write runtime call trees power consumption in a CSV file. For each monitoring cycle (1 second), a new CSV file will be generated, containing the runtime power consumption of the call trees. The generated files will include timestamps in their names.
 - ```overwrite-call-trees-runtime-data```: overwrite runtime call trees power data file, or if set to false, it will write new file for each monitoring cycle.
 - ```application-server```: properly handles application servers and frameworks (Sprig Boot, Tomcat, etc.). Set ```true``` when running on application servers. If false, the monitoring loop will check if the JVM is destroyed, hence closing JoularJX when the application ends (in regular Java application). If true, JoularJX will continue to monitor correctly as the JVM isn't destroyed in a application server.
+- ```vm-power-path```: the path for the power consumption of the virtual machine. Inside a virtual machine, indicate the file containing power consumption of the VM (which is usually a file in the host that is shared with the guest).
+- ```vm-power-format```: power format of the shared VM power file. We currently support two formats: ```watts``` (a file containing one float value which is the power consumption of the VM), and ```powerjoular``` (a csv file generated by [PowerJoular](https://github.com/joular/powerjoular) in the host, containing 3 columns: timestamp, CPU utilization of the VM and CPU power of the VM).
 
 You can install the jar package (and the PowerMonitor.exe on Windows) wherever you want, and call it in the ```javaagent``` with the full path.
 However, ```config.properties``` must be copied to the same folder as where you run the Java command.
 
+In virtual machines, JoularJX requires two steps:
+- Installing a power monitoring tool in the host machine, which will monitor the virtual machine power consumption every second and writing it to a file (to be shared with the guest VM).
+For example, you can use our [PowerJoular](https://github.com/joular/powerjoular).
+- Use JoularJ in the guest VM while specifying the path of the power file shared with the host and its format.
