Vmware Side Channel Aware Scheduler

Aware

4. Solution

In vSphere 6.7 U2, the side-channel aware scheduler has been enhanced (SCAv2) with a new policy to allow hyper-threads to be utilized concurrently if both threads are running vCPU contexts from the same VM. In this way, L1TF side channels are constrained to not expose information across VM/VM or VM/hypervisor boundaries. To identify the usable GHz capacity of a physical server acting as an ESXi host, look in vSphere ESXi's screen for Resource Allocation, CPU section, Total Capacity and take 90% of that number (reflecting VMware recommendation to leave 10% per host unreserved - see vSphere ESXi 6.0 Resource Management Guide in Technical References).
