You want to be able to monitor and filter vm-to-vm traffic within a virtual network.

VM information sources provides an automated way to gather information on the Virtual Machine (VM) inventory on each monitored source (host); the firewall can monitor the VMware ESXi, vCenter Server, AWS-VPC, Microsoft Azure VNet, and Google Cloud. As virtual machines (guests) are deployed or moved, the firewall collects a predefined set of attributes (or metadata elements) as tags; these tags can then be used to define Dynamic Address Groups (see Use Dynamic Address Groups in Policy) and matched against in policy.

You can directly configure the firewall or use Panorama templates to monitor up to 10 VM information sources.

VM Information Sources

offers easy configuration and enables you to monitor a predefined set of 16 metadata elements or attributes. See Attributes Monitored on Virtual Machines in Cloud Platforms for the list. By default, the traffic between the firewall and the monitored sources uses the management (MGT) port on the firewall.

  • When monitoring ESXi hosts that are part of the VM-Series NSX edition solution, use Dynamic Address Groups instead of using VM Information Sources to learn about changes in the virtual environment. For the VM-Series NSX edition solution, the NSX Manager provides Panorama with information on the NSX security group to which an IP address belongs. The information from the NSX Manager provides the full context for defining the match criteria in a Dynamic Address Group because it uses the service profile ID as a distinguishing attribute and allows you to properly enforce policy when you have overlapping IP addresses across different NSX security groups. Up to a maximum of 32 tags (from vCenter server and NSX Manager) that can be registered to an IP address.

  • For monitoring the virtual machines within your Azure deployment, instead of VM Monitoring Sources, you need to deploy the VM Monitoring script that runs on a virtual machine within the Azure public cloud. This script collects the IP address-to-tag mapping information for your Azure assets and publishes it to the firewalls and corresponding virtual systems you specify in the script.

  1. Enable VM Monitoring.

    You can configure up to 10 VM information sources for each firewall, or for each virtual system on a multiple virtual systems capable firewall.

    If your firewalls are configured in a high availability configuration:

    • In an active/passive setup, only the active firewall monitors the VM sources.

    • In an active/active setup, only the firewall with the priority value of primary monitors the VM sources.

    1. Select . This example shows you how to add VMware ESX(i) or vCenter Server.

    2. Click

      Add

      and enter the following information:

      • A

        Name

        to identify the source that you want to monitor.

      • Enter the

        Host information for the server—

        hostname or IP address and the

        Port

        on which it is listening.

      • Select the

        Type

        to indicate whether the source is an

        AWS VPC

        , a

        Google Compute Engine

        instance, a

        VMware ESX(i)

        server, or a

        VMware vCenter

        Server.

        The type chosen determines the fields displayed.

      • Add the credentials (

        Username

        and

        Password

        ) to authenticate to the server specified above.

      • Use the credentials of an administrative user to enable access.

      • (

        Optional

        ) Modify the

        Update interval

        to a value between 5-600 seconds. By default, the firewall polls every 5 seconds. The API calls are queued and retrieved within every 60 seconds, so updates may take up to 60 seconds plus the configured polling interval.

        You want to be able to monitor and filter vm-to-vm traffic within a virtual network.

      • (

        Optional

        ) Enter the interval in hours when the connection to the monitored source is closed, if the host does not respond. (range is 2-10 hours; default is 2).

        To change the default value, select the check box to

        Enable timeout when the source is disconnected

        and specify the value. When the specified limit is reached or if the host cannot be accessed or does not respond, the firewall will close the connection to the source.

      • Click

        OK

        , and

        Commit

        the changes.

      • Verify that the connection

        Status

        displays as connected.

  2. Verify the connection status.

    Verify that the connection

    Status

    displays as connected.

    If the connection status is pending or disconnected, verify that the source is operational and that the firewall is able to access the source. If you use a port other than the MGT port for communicating with the monitored source, you must change the service route (, click the

    Service Route Configuration

    link and modify the

    Source Interface

    for the

    VM Monitor

    service).

Which type of virtualization allows applications to run within the virtual machine without being modified in any way?

In full virtualization, the virtual machine completely simulates a real physical host. This allows most operating systems and applications to run within the virtual machine without being modified in any way.

How does a virtual machine monitor work?

Virtual machine monitor (VMM): The program that is used to manage processor scheduling and physical memory allocation. It creates virtual machines by partitioning the actual resources, and interfaces the underlying hardware (virtual operating platform) to all operating systems (both host and guest).

What are the requirements of virtual machine monitor?

There are three requirements for a VMM. First, a VMM should provide an environment for pro-grams which is essentially identical to the original machine. Second, programs run in this environment should show, at worst, only minor decreases in speed. Third, a VMM should be in complete control of the system resources.

What is virtual machine monitor give two examples?

The VMM kernel runs alongside the host OS, and calls for I/O are redirected to virtual drivers that call the native API of the host OS. Examples of OS-hosted VMMs are VMware Workstation, VMware Server, Parallels Workstation and Parallels Desktop for Mac.
