2014-10-03 Thread Eduardo Habkost
TCG doesn't support VMX, and nested VMX is not enabled by default on the KVM kernel module. So, there's no reason to have VMX enabled by default on the core2duo and coreduo CPU models, today. Even the newer Intel CPU model definitions don't have it enabled. In this case, we need machine-type comp
