# `Hyper.Vm.Instance.Spec`
[🔗](https://github.com/harmont-dev/hyper/blob/main/lib/hyper/vm/instance/spec.ex#L1)

Resource bundle for one instance type.

# `t`

```elixir
@type t() :: %Hyper.Vm.Instance.Spec{
  disk: Unit.Information.t(),
  disk_bw: Unit.Bandwidth.t(),
  mem: Unit.Information.t(),
  net_bw: Unit.Bandwidth.t(),
  vcpus: number()
}
```

# `cgroup_v2`

```elixir
@spec cgroup_v2(t()) :: Sys.Linux.Cgroup.V2.Config.t()
```

# `machine_config`

```elixir
@spec machine_config(t()) :: Hyper.Firecracker.Api.MachineConfiguration.t()
```

Firecracker machine-config for this spec, the guest-facing analog of
`cgroup_v2/1`. `vcpus` is a fractional cgroup quota; the guest needs a positive
integer count, so it's rounded up and floored at 1 (a 0.25-vCPU `:micro` still
presents one vCPU). Memory is the spec's `mem` in MiB.
