Some 1-CPU guests have only one thread though?


Are you sure they're using kvm? Try 'info kvm' in the monitor. tcg will only use on thread (more will be spawned for I/O, but will eventually die).

Indeed, that was a good suggestion - they were not using KVM (support not compiled in, and kvm didn't complain when starting).

IO and CPU speed was rather OK, so I didn't notice ;)

To sum up the thread: I guess qemu _without_ KVM will only use one CPU, even when you assign more CPUs to the guest?
