QEMU System X86-64 Command Breakdown

Command Overview

The provided command is used to launch a QEMU virtual machine on an x86-64 system.

Options and Parameters

• qemu-system-x86_64: The QEMU emulator for x86-64 architecture.
• -monitor stdio: Sets the monitor to use standard input/output for console interaction.
• -device ati-vga: Enables an ATI VGA graphics device for the virtual machine.
• -enable-kvm: Enables KVM (Kernel-based Virtual Machine) acceleration for the virtual machine.
• -accel hvf: Enables the Hax Virtualization Framework (HVF) for improved performance on Intel systems.
• -smp 2: Specifies the number of virtual CPUs (2) for the virtual machine.
• -m 3G: Allocates 3 GB of memory for the virtual machine.
• -net nic,model=virtio: Enables a virtio network interface for the virtual machine.
• -net user,hostname=windowsvm: Enables a user-mode network interface for the virtual machine, with the specified hostname.
• -drive if=ide,index=1,media=cdrom,file="": Mounts an empty CD-ROM drive at IDE index 1.
• -drive file="./Parallels/Windows 10.pvm/harddisk.hdd/harddisk.hdd.0.{5fbaabe3-6958-40ff-92a7-860e329aab41}.hds",if=none,id=windowshdd: Mounts a virtual hard disk file at an idle interface, with the specified ID.
• -device virtio-blk-pci,drive=windowshdd,bus=pci.0,bootindex=2: Configures the virtio block device at PCI bus 0, with the specified boot index.

Virtual Machine Configuration

This command is used to launch a virtual machine with the following characteristics:

• 2 virtual CPUs
• 3 GB of memory
• ATI VGA graphics device
• Virtio network interface
• User-mode network interface with the hostname "windowsvm"
• A virtual hard disk file mounted at an idle interface
