We had this discussion at the Ops Mid-Cycle meetup. I think the general
consensus was 0.9 for memory. if you're running Ceph OSD's on the node
you'll almost certainly want to reserve more than a gig for it and the OS.
for CPU there was a wide range of ideas and it mainly depended on use-case.
If
Just a general question: what kind of over commit ratios do people
normally run in production with?
We currently run 2 for cpu and 1 for memory (with some held back for OS/ceph)
i.e.:
default['bcpc']['nova']['ram_allocation_ratio'] = 1.0
default['bcpc']['nova']['reserved_host_memory_mb'] = 1024
I think you might have misunderstood the nature of this list.
We often times do provide answers to common issues, but this is not a support
organization.
You've provided no details of the errors you're experiencing, so it would be
very difficult to help.
