Trait Implementations

impl BootConfigurator for LinuxBootConfigurator

fn write_bootparams<M>(params: &BootParams, guest_memory: &M) -> Result<()>

where M: GuestMemory,

Writes the boot parameters (configured elsewhere) into guest memory.

Arguments

• params - boot parameters. The header contains a boot_params struct. The sections and modules are unused.
• guest_memory - guest’s physical memory.

Examples

fn build_bootparams() -> boot_params {
    let mut params = boot_params::default();
    params.hdr.boot_flag = KERNEL_BOOT_FLAG_MAGIC;
    params.hdr.header = KERNEL_HDR_MAGIC;
    params.hdr.kernel_alignment = KERNEL_MIN_ALIGNMENT_BYTES;
    params.hdr.type_of_loader = KERNEL_LOADER_OTHER;
    params
}

fn main() {
    let guest_memory = create_guest_memory();
    let params = build_bootparams();
    let mut bootparams = BootParams::new::<boot_params>(&params, zero_page_addr);
    LinuxBootConfigurator::write_bootparams::<GuestMemoryMmap>(&bootparams, &guest_memory)
        .unwrap();
