I have been trying to run ht kvm cpu when using multiple cores. With
single threaded simulation, the simulation stops making progress if the
simulated system has more than 4 cores. With multi-threaded simulation, I
do not see any progress even when two cores are being simulated. For the
multi-threaded simulation, I made the following changes as suggested in
the comment for the changeset: 10157:5c2ecad1a3c9. So, how many cores
have others tested kvm cpu with? Is there something that I might not be
doing right?
