It happens since os_daemonize() where moved before it later on, given no one actually complained since then we probably do not care about it.

There is no reason to prevent -preconfig -daemonize. Of course if no monitor is defined there will be no way to start the VM, but that is a user error. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> --- softmmu/vl.c | 6 ------ 1 file changed, 6 deletions(-)
