Patchwork [meta-oe] If QEMU parameters are extended to emulate additional network interfaces, NFS boot does not work. Based on the ip configuration provided by the runqemu-internal script the kernel is not able to use the right interface for the nfs mount.

Adrian - June 25, 2014, 8:24 p.m.
From: Adrian Freihofer <adrian.freihofer@neratec.com>

Example to reproduce:
runqemu ... qemuparams="-net nic,model=virtio... -net tap, ..."

If kernel parameters are extended to get the kernel forced to use
eth0 for the nfs rootfs another issue pops up. The script which creates
a special config for connman fails. It creates an invalid configuration
for connman which ends up in a nfs disconnection again.

[YOCTO #6356]
