The userspace process is qemu.

I compiled qemu from latest source, installed via "sudo make install"
on host-machine, rebooted the host-machine, and booted up the
guest-machine on the host-machine. Now, no kernel-flooding is seen on
the host-machine.

For me, the issue is thus closed-invalid; admins may take the
necessary action to officially mark ;)


Thanks and Regards,
