Enum VmCreateError 

pub enum VmCreateError {
    TooSmall {
        requested: usize,
        required: usize,
    },
    BadSize {
        requested: usize,
        unit: usize,
    },

    },

    },
}

Variants

TooSmall

the requested VM was smaller than asmlinator’s minimum allowable size.

Fields

requested: usize

required: usize

BadSize

the requested VM’s memory size was not an even number of pages.

Fields

requested: usize

unit: usize

SyscallError

one of the several syscalls in setting up a new VM failed.

this is most likely a permissions error, or /dev/kvm doesn’t exist. otherwise, something interesting happened!

this deserves better documentation, but i’m not aware of documentation for KVM ioctl failure modes.

Fields

op: &'static str

err: Errno

InvalidMapping

base and size are not valid for mapping; either because of over/underflow, or overlaps with an existing mapping.

Fields

base: GuestAddress

size: u64
