Of HyperThreading and C states...

robFeb 11 2013 — edited Feb 14 2013

Good Morning/Afternoon/Evening!

We've been validating as much of our configuration as is possible given our general OVM stability issues, and received a recommendation from Oracle to disable HyperThreading and C states for our x4470-m2 servers. We also found documentation that said we should disable VT-d, which we also disabled.

I'm wondering if anybody has any real world experience on these fronts. I'd rather have HyperThreading available if it won't undermine stability. They tech said generally you can't have Virtualization Extensions and HyperThreading on at the same time, but we're able to with our systems.

What kind of setups are you all using? We're on VM 3.1.1.

Thanks!

Rob
