Could you clarify what you mean here? Is this specifically a Unikernel problem or an ecosystem problem (in terms of actually trying to deploy Unikernels in the wild)? If so, those seem like different issues and should be discussed separately.
- wmf 12y agoIt's a cloud provider problem, but I don't think a technology can be usefully separated from its ecosystem. The cloud can remain irrational longer than you can remain solvent. On a technical level, VM memory hotplug is probably necessarily slower and flakier (ACPI anyone?) than changing one setting in a cgroup.
