KVM is a popular virtualization solution in the linux environment. Deploying multiple VMS on a network greatly improves deployment efficiency and reduces physical resource consumption. The following describes the process for deploying multiple VMS in a network environment.

Ensure that the KVM and dependency packages have been installed on the host, and prepare an OS image to be installed on the VM over the network. Install HTTP server software, such as apache or Nginx, and place the ISO file of the operating system in the accessible directory of the HTTP server. Configure KVM VMS to boot from the network and point to the server URL as the installation source.

The FTP server can be used as the network installation source. Configure the FTP server as the network installation source to ensure that the OS image file is accessible. The FTP server address and required login credentials are specified in the KVM VM startup configuration. The virtual machine downloads the installation file from the FTP server.

NFS supports a more efficient way to share files and is used in scenarios that require high-performance network installation. Install and configure the NFS server, and export the OS installation tree to the NFS share. In the network configuration of the KVM VM, add an NFS client and mount the NFS share. Start the virtual machine from the NFS share and begin the installation process.

Deploy the virtual machine with the virt-install command or through the libvirt graphical interface. You need to specify the type of network installation source (HTTP, FTP, or NFS) and the associated URL or server address.

After the deployment is complete, use the virsh command line tool or graphical management tool to monitor and manage VMS. You can view VM status, take snapshots, and migrate VMS.

Deploying KVM VMS over a network is an efficient and flexible way. It is suitable for the scenario where a large number of VMS need to be rapidly deployed. The preceding content helps you quickly learn how to deploy and manage multiple VMS using HTTP, FTP, and NFS as the network installation source.

Check network connections and firewall Settings to ensure that virtual machines have access to network installation sources and that operating system image files are intact. Consider automated scripts to simplify the deployment and management of virtual machines.
