2. In the left navigation, click on **Download agents**.

3. Click on the **Linux** tile \> click **Next**.

     1. In the **Machines group** drop down list, select the group the the Linux OpenStack instance should be included in
     2. In the **Select target Linux distribution** drop down list, select either **Debian/Ubuntu (.deb package)** or **CentOS/REHL(.rpm package)** depeneding on the OpenStack instance to protect.
     3. In the **Snapshot driver deployment type** drop down list, choose the appropriate option. 
            1. For **Pre-build (the driver is provided in binary format),** the pre-built driver package requires no additional dependencies, but the supported Linux kernel list is limited. Use pre-built package for machines that are infrequently updated or have no Internet connection to install DKMS and other dependencies.
            2. For **DKMS (The driver is built during agent installation)**, the DKMS driver package will build the driver on installation. It has a broad Linux kernel support and will rebuild the driver on kernel updates. It requires DKMS, build tools and kernel headers to be installed on the machine. Use DKMS package for machines that are frequently updated or not supported by the pre-built package.
     4. Click **Next**.

   ![](https://kb.vsystems.com/hs-fs/hubfs/image-png-Oct-08-2026-01-04-34-6839-AM.png?width=670&height=214&name=image-png-Oct-08-2026-01-04-34-6839-AM.png)
5. Copy the package to the Linux machine you would like to protect. Use deb package for Ubuntu/Debian machines and rpm package for RHEL/CentOS machines.
6. Install the agent using the following commands (superuser privileges required): 
     - For Ubuntu/Debian machines: `dpkg -i hlragent.deb`
     - For RHEL/CentOS machines: `rpm -i hlragent.rpm`
7. The machine will be registered and shown in a target group in a few minutes after agent installation. By default, the discovered machine has 'Unprotected' status.
8. To start protection, select the machine and use 'Actions \> Start Protection'.
