The second "Note:" in https://wiki.qemu.org/Documentation/Networking
says "don't try to use ping to test if you're using usermode networking",
because it won't work.

The underlying issue is that by default the host OS will not allow
random unprivileged processes like QEMU to send ping packets.
If you're using a Linux host and have root access on it it is possible
to configure it to allow your user to send ping packets:
but personally I don't bother, I just don't try to use ping in the guest.
