[OE-core] [meta-oe][PATCH 0/3] runqemu improve networking

[Adrian Freihofer]

Hi Aws

The interfaces of my virtual device are configured as:
eth0: static IP, 192.168.7.2 (This IP is hard coded in many scripts of poky.)
      This interface is for debugging purpose, it is not available
      on my physical devices running in a productive environment.
      The interface is configured by the kernel command line
      provided by the runqemu script. This interface should
      (or must in case of NFS rootfs) be ignored by connman, networkmanager
      or what ever manages the network settings of your device.
eth1: Configured by connman or networkmanager running on the virtual device.
      The part of the setup depends on the particular use case you need
      to emulate. In my setup the tap interfaces of the host ar part
      of a bridge. On the bridge a dnsmasq instance serves IP addresses.
      This part of my setup is not published. It is verry specific. But based
      on my patch set it should be easy to do something similar fitting your
      use case. The simplest approach might be a static IP address e.g.
      assigned by a bbappend file e.g. for connman.

runqemu is started with additional parameters to create eth1:
runqemu hostonly qemuparams="-device virtio-net-pci,netdev=netif1,mac=${macaddr1} -netdev
tap,id=netif1,ifname=${HOST_TAP_NAME},script=no,downscript=no"

Regards,
Adrian
