cpu

My host has 4 cores 8 threads. Does it make sense to allocate 8 vCPU to all my LXC and VMs if I know that none of them will ever max out all 8vCPU at the same time? I'm not sure if that will create any scheduling issue or overhead as compares to allocate a smaller number to each of them. I saw a...
