From the Command Line Binary

There are two options for displaying the information for VMs in an experiment. First run the following command to see information for all VMs in a given experiment.

phenix vm info <experiment name>

Or, run the following to see the information for a specific VM in an experiment.

phenix vm info <experiment name> <vm name>

Create a Backing Image

From the Web-UI

Click on the name of a running VM in a started experiment to access the VM information modal. Click the create backing image button as shown in the screenshot below.

Packet Capture

From the Web-UI

Click on the name of the network tap on a running VM in a started experiment to start a packet capture. The name of the network tap will turn green once a packet capture has started. It is possible to start captures on multiple network taps. However, when you stop packet capture, it will stop captures on all network taps.

From the Command Line Binary

To start a packet capture, run the following command.

phenix vm capture start <experiment name> <vm name> <iface index> </path/to/out file>

To stop all packet captures on a running VM, use the following command.

phenix vm capture stop <experiment name> <vm name>

Kill a VM

From the Web-UI

Click on the name of a running VM in a started experiment to access the VM information modal. Click the modify state button on the far right to open the modify state toolbar. Click the kill button as shown in the screenshot below.

Note: if you stop and then start the experiment again, that VM will run again per the experiment configuration.

From the Command Line Binary

To kill a VM, run the following command.

phenix vm kill <experiment name> <vm name>

Modify the Network Connectivity

Click on the network for the desired VM in the Running Component to modify the settings. Select from a pull down what network you want to switch the VM interface you clicked on to. To revert back to previous setting, simply repeat selecting the network interface you wish to change, and select the previous network setting.

From the Command Line Binary

To connect a VM network interface to a different network, run the following command.

phenix vm net connect <experiment name> <vm name> <iface index> <vlan id>

To disconnect a VM network interface, run the following command.

phenix vm net disconnect <experiment name> <vm name> <iface index>

Pause a VM

Modify VM Settings

From the Web-UI

There are two ways to modify VM settings:

1. Click on a stopped experiment to access the Stopped Component. You are able to edit the following:
   • Host name
   • CPUs
   • Memory
   • Disk
   • Do not boot flag
2. From a running experiment, click on the VM name and then the redeploy button (yellow power button, second from the right on the modal footer). You are able to edit the following:
   • CPU
