virt-install: Create a virtual machine with 16 GiB RAM, 250 GiB storage, 8 cores with hyperthreading, a specific CPU topology, and a CPU model that shares most features with the host CPU.

virt-install

$ virt-install --name ${vm_name} --cpu ${host-model},topology.sockets=${1},topology.cores=${4},topology.threads=${2} --memory ${16384} --disk path=${path-to-image-qcow2},size=${250} --cdrom ${path-to-debian-iso}

This command is used to create and install a virtual machine using the "virt-install" tool.

Here is a breakdown of the command and its options:

virt-install: This is the actual command to create and install a virtual machine.
--name ${vm_name}: Sets the name of the virtual machine. ${vm_name} is a placeholder that should be replaced with the desired name.
--cpu ${host-model},topology.sockets=${1},topology.cores=${4},topology.threads=${2}: Defines the CPU configuration for the virtual machine. ${host-model} represents the CPU model of the host machine. ${1}, ${4}, and ${2} are placeholders that should be replaced with the desired number of sockets, cores, and threads respectively.
--memory ${16384}: Sets the amount of memory (RAM) allocated to the virtual machine. ${16384} is a placeholder that should be replaced with the desired amount in megabytes.
--disk path=${path-to-image-qcow2},size=${250}: Specifies the disk configuration for the virtual machine. ${path-to-image-qcow2} should be replaced with the desired path to the image file in QCOW2 format. ${250} is a placeholder that should be replaced with the desired disk size in gigabytes.
--cdrom ${path-to-debian-iso}: Sets the path to the ISO image file that will be used to install the operating system. ${path-to-debian-iso} should be replaced with the actual path to the ISO file.

Overall, this command creates a virtual machine with the specified name, CPU configuration, memory allocation, disk configuration, and starts the installation process using the provided ISO image file.
