From d4073dedbb234ff3c6bbebafc836fedf90d96569 Mon Sep 17 00:00:00 2001 From: Pavel Zhukov Date: Tue, 18 Apr 2023 15:33:25 +0200 Subject: [PATCH] scripts/runqemu: Add possibility to disable network Default network configuration requires tun/tap module and while being usable it conflicts with tap devices created by VPN clients sometimes and requires root permissions to use . While it's possible to work this around it's not always feasible if network is not required Add nonetwork option which can be specified if the network connectivity is not needed and SDL/serial is enough to communicate with the image.
