Hi,
I've got a two nodes cluster running ve 1.4.
I've set up one kvm-vm with one cpu.
when i run "dd if=/dev/zero of=/test bs=1M count=5000 oflag=direct,sync" inside the vm, the context-switches (vmstat -S m 1) grow up to 23000 and the io-wait is round about 40%. the kvm process is threading around over 16 CPU cores and the system slows down.
Is it possible to disable threading in kvm?
