Re: Amidst all the wailing and knashing of teeth here
Linux has long had pretty much everything you say it doesn't:
Live OS upgrades: KSplice has been around for a decade.
Inline memory compression: Compcache / zram has been around for a decade, also.
Hypervisor overcommit memory: KVM has had over-commit for at least a decade, Xen even longer. VMware longer still.
ASO/DSO (automatically tune the operating system: Linux systems need vastly less (if any) tuning of parameters, compared to traditional crufty Unix systems.
Workload Partitions: Linux has rather advanced containers in OpenVZ/LXC/Xen for over a decade.
Suspend / Resume: KVM/LXC/etc. suspend / resume just fine.
