From a00b94900d437828f25debce1c30ffcc0bbf29e9 Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Wed, 14 Dec 2011 16:37:24 +0000 Subject: scripts/runqemu: show an error if /dev/net/tun is unusable If /dev/net/tun is either not present or is not writable by the user, then show an appropriate error message. (QEMU needs access to this device in order to enable networking; it may be missing if it is not enabled or loaded into the kernel, and some distributions such as CentOS 5.x set restrictive permissions upon it.)
