Hyper.Vm.Instance.Spec (Hyper v0.1.0)

Resource bundle for one instance type.

Summary

Types

t()

Functions

cgroup_v2(spec)
machine_config(spec)

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.
