[oi-dev] [developer] suspend/resume in Illumos

[Garrett D'Amore]

That’s only true if you’re running on  a hypervisor that uses suspend / resume for live migration.  I’m not sure how widespread running illumos on VMware is – the absence of suspend/resume support means that nobody is benefiting from this particular capability today (at least with illumos).

Suspend and Resume is critical for live migration in a data center with external storage to reduce schedules downtime incurred with firmware updates to maintain a secure platform.

While graphics and wifi drivers might be worked around by careful choice of hardware for a new rig, effective lack of sleep/hibernate is a big problem.
