Types

type Config

type Config struct {
	Count    int    `json:"count"`     // number of VMs to run in parallel
	Qemu     string `json:"qemu"`      // qemu binary name (qemu-system-arch by default)
	QemuArgs string `json:"qemu_args"` // additional command line arguments for qemu binary
	// 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"`
	Initrd  string `json:"initrd"` // linux initial ramdisk. (optional)
	// 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"`
	CPU         int    `json:"cpu"`      // number of VM CPUs
	Mem         int    `json:"mem"`      // amount of VM memory in MiB
	Snapshot    bool   `json:"snapshot"` // For building kernels without -snapshot (for pkg/build)
}
