Types

type Config

type Config struct {
	// Number of VMs to run in parallel (1 by default).
	Count int `json:"count"`
	// QEMU binary name (optional).
	// If not specified, qemu-system-arch is used by default.
	Qemu string `json:"qemu"`
	// Additional command line arguments for the QEMU binary.
	// If not specified, the default value specifies machine type, cpu and usually contains -enable-kvm.
	// If you provide this parameter, it needs to contain the desired machine, cpu
	// and include -enable-kvm if necessary.
	// "{{INDEX}}" is replaced with 0-based index of the VM (from 0 to Count-1).
	// "{{TEMPLATE}}" is replaced with the path to a copy of workdir/template dir.
	// "{{TCP_PORT}}" is replaced with a random free TCP port
	// "{{FN%8}}" is replaced with PCI BDF (Function#%8) and PCI BDF Dev# += index/8
	QemuArgs string `json:"qemu_args"`
	// Location of the kernel for injected boot (e.g. arch/x86/boot/bzImage, optional).
	// This is passed to QEMU as the -kernel option.
	Kernel string `json:"kernel"`
	// Additional command line options for the booting kernel, for example `root=/dev/sda1`.
	// Can only be specified with kernel.
	Cmdline string `json:"cmdline"`
	// Initial ramdisk, passed via -initrd QEMU flag (optional).
	Initrd string `json:"initrd"`
	// QEMU image device.
	// The default value "hda" is transformed to "-hda image" for QEMU.
	// The modern way of describing QEMU hard disks is supported, so the value
	// "drive index=0,media=disk,file=" is transformed to "-drive index=0,media=disk,file=image" for QEMU.
	ImageDevice string `json:"image_device"`
	// EFI images containing the EFI itself, as well as this VMs EFI variables.
	EfiCodeDevice string `json:"efi_code_device"`
	EfiVarsDevice string `json:"efi_vars_device"`
	// QEMU network device type to use.
	// If not specified, some default per-arch value will be used.
	// See the full list with qemu-system-x86_64 -device help.
	NetDev string `json:"network_device"`
	// Number of VM CPUs (1 by default).
	CPU int `json:"cpu"`
	// Amount of VM memory in MiB (1024 by default).
	Mem int `json:"mem"`
	// For building kernels without -snapshot for pkg/build (true by default).
	Snapshot bool `json:"snapshot"`
	// Magic key used to dongle macOS to the device.
	AppleSmcOsk string `json:"apple_smc_osk"`
