In net/tap-linux.c, when manipulation of /dev/net/tun fails, it prints
(with fprintf) something like this:
warning: could not open /dev/net/tun: no virtual network emulation
this has 2 issues:
1) it is not a warning really, it's a fatal error (kvm exits after
that),
2) there's no indication as of what's actually wrong: printing errno there
is helpful.
The patch below removes the "warning" prefix, uses %m (since it's linux,
%m is available as format modifier), and changes fprintf() to %qemu_error().
Now it prints something like this instead:
could not configure /dev/net/tun: Device or resource busy
(there are 2 messages like that in the same function)
This fixes Debian bug #578154, see
