Install Security Director Insights With KVM virt-manager

Before You Begin

  • Ensure that there are no snapshots. You must delete the snapshot before expanding the disk size.

  • We recommend to create a backup by cloning the VM before expanding the disk size.

You can install and launch Security Director Insights with the KVM virt-manager GUI package.

Before you begin, you must ensure:

  • You have already installed KVM, qemu, virt-manager, and libvirt on your host OS.

  • You have created a bridge network to access KVM through SSH.

    In this document, a bridge network br0 is created with Netplan. Figure 1 shows an example configuration from the /etc/netplan/00-installer-config.yaml file.

To install Security Director Insights with virt-manager:

  1. Download the Security Director Insights KVM image from the Juniper software download site.
  2. On your host OS, type virt-manager.

    The Virtual Machine Manager page appears, as shown in Figure 2.

    Note:

    You must have admin rights on the host OS to use virt-manager.
  3. Click the Create a new virtual machine icon, as shown in Figure 3.

    The Create a new virtual machine page appears.

  10. In the Network selection field, select the bridge network (typically br0) from the list.
  11. Click Finish.
  12. Click Add Hardware, as shown in Figure 8.

    The Add New Virtual Hardware page appears.

    The VM manager creates the virtual machine and launches the Security Director Insights console.

Expand the VM Disk Size

Procedure

To expand the disk to the maximum available size in a KVM virt-manager:

  1. Log in to the host of the KVM and power down the VM, as shown in Figure 11.

    Figure 11: Power Down the VM Virtual Machine Manager interface showing VM 'jsa' running and 'sdiq-disk' shut off. Tooltip: Shut down VM option. CPU usage graphs on right.

  2. From the host, increase the disk size using the qemu-img resize vmdisk.img +XG command, where vmdisk.img is the name of the image and XG is the size in GB you want to expand the disk to.Terminal showing qemu-img command to resize disk image by 200GB confirming successful operation.

    The size denotes how much you want to expand the disk. It is not the maximum size of the disk.

  3. Power on KVM and log in to the Admin CLI. Switch to the server mode and run set disk-partition-to-full command. Terminal displaying partition resizing with sgdisk, lsblk showing disk details, resize2fs for ext4 resizing, and df listing mounted filesystems.

    The new disk size is the size of /dev/vda2.
