How nova calculates vCPUs when hyper-threading is enabled in OpenStack
Issue
- How does
nova
calculate virtual CPUs when hyper-threading is enabled? - How to calculate the vCPU count on a compute node?
- Does the
nova scheduler
take hyper-threading into consideration when calculating availablevcpus
on a compute node? - How does hyper-threading affect CPU overcommit when
cpu_allocation_ratio
is above a value of 1?
Environment
- Red Hat OpenStack Platform (OSP) 10, 13
