My understanding is that a new 'struct kvm' is created on the target machine and this flag should be reset, which would allow the VMM to restore the firmware registers. However, we would be running KVM_RUN for the first time on the target machine, thus setting the flag. So, you are right; It's more of a resume operation from the guest's point of view. I guess the name of the variable is what's confusing here.
