The command "virt-manager --show-host-summary" is used to launch the Virt-Manager application in the host summary mode.
Virt-Manager is a graphical user interface tool used for managing virtual machines (VMs) and hypervisors on Linux systems. It allows users to create, edit, start, stop, and manage VMs using different hypervisors like QEMU, KVM, Xen, and others.
When you run the command "virt-manager --show-host-summary" in the terminal, it launches the Virt-Manager application in the host summary mode. The host summary mode provides an overview of the host system's current status and information. It displays the details about the host's CPU, memory, storage, network connections, and other relevant information.
This mode is useful for understanding the resources and capabilities of the host system before creating or managing virtual machines. It helps in making decisions related to virtualization and ensures that the host system has the necessary resources to handle the VMs effectively.
