Please excuse me if this is a stupid question, however, I'm curious why I'm not seeing any clock speed differences when using fedora as a guest VM via KVM/QEMU.
Perhaps this is a rather dumb way of concluding such things, but when I do cat /proc/cpuinfo | grep MHz it's always the same and it's the base clock speed advertised by my xeons.
Is there some option I have to pass virsh to enable turbo boost?
This might be helpful:
