Title: KVM Test: client: Catch exceptions derived from Exception class only

Now autotest is using try/except without parameter, which will catch all exception,
include KeyboardInterrupt exception, it causes some autotest process ignore "ctrl-c"
key event.

This patch will add "Exception" parameter for these separated "except", so that we
can terminate all autotest processes by press "ctrl-c"

For more details, please refer to
