I think this is the best CPU scheduling concept explanation out there. Thanks!

Couldn’t you relieve CPU skew by alternating the core usage on the 4vCPU VM, so that:
1. in hostCPU timeslot 1 it uses all 4 hostCores
2. in hostCPU timeslot 2 it uses 2 hostCores running its vCPUs 1 and 2 while the other 2 hostCores are used by VM2
3. in hostCPU timeslot 3 it uses all 4 hostCores (vCPUs 1 and 2 are now each 1 step ahead of vCPUs 3 and 4)
4. in hostCPU timeslot 4 it uses 2 hostCores running its vCPUs 3 and 4 while the other 2 hostCores are used by VM2 (all 4 vCPUs of VM1 are now on the same step again, no skew, no CoStop)

We have a host with two CPU and 8 Core Per Socket which is 2 CPU with 16 Core, our CPU is Intel(R) Xeon (R) CPU X7560 @ 2.27GHz
we need to know what is the Number of vCPU in this case?
we need to know what is the total Number of GHz in this Host?
we need to know what is the number of GHz for VM that has 2 CPU and 2 Core (4vCPU)
could you help plz

In this Video at 18:56 slot, what happens if the VM 1 really uses the 70% of the CPU?
