Issue

Need clarification on the effect of CPU Hyperthreading enabled at BIOS level with CPU pinning at the Hypervisor level
Consider a system with:
- 4 Sockets
- 8 Cores
- 2 Threads
Using CPU pinning
Requires NUMA boundaries to be respected
Is CPU allocation done on a Core level (0-31) or on a Thread Level (0-63)?
Is there a performance benefit to disabling Hyperthreading at the BIOS level?
Does Red Hat and RHEVM account for Hyperthreading behind the scenes?
