Title:
  no useful error message when tap device open fails

Status in QEMU:
  Fix Released
Status in “qemu-kvm” package in Debian:
  Fix Released

Bug description:
  When using tap network devices and it fails, qemu gives no information
  about what the problem is (permission denied, device busy or other),
  making debugging of such situations, especially for newbies, very
  difficult.  The proposed patch just adds strerror() around the place,
  making it more friendly.
