Trait Implementations

impl KernelLoader for BzImage

Available on crate feature bzimage only.

fn load<F, M: GuestMemory>( guest_mem: &M, kernel_offset: Option<GuestAddress>, kernel_image: &mut F, highmem_start_address: Option<GuestAddress> ) -> Result<KernelLoaderResult>

where F: ReadVolatile + Seek,

Loads a kernel from a bzImage to guest memory.

The kernel is loaded at code32_start, the default load address stored in the bzImage setup header.

Arguments

• guest_mem: GuestMemory to load the kernel in.
• kernel_offset: Address in guest memory where the kernel is loaded.
• kernel_image - Input bzImage image.
• highmem_start_address: Address where high memory starts.

Examples

let mem_size: usize = 0x1000000;
let himem_start = GuestAddress(0x0);
let kernel_addr = GuestAddress(0x200000);
let gm = GuestMemoryMmap::from_ranges(&[(GuestAddress(0x0), mem_size)]).unwrap();
let mut kernel_image = vec![];
kernel_image.extend_from_slice(include_bytes!("bzimage"));
bzimage::BzImage::load(
    &gm,
    Some(kernel_addr),
    &mut Cursor::new(&kernel_image),
    Some(himem_start),
)
.unwrap();
