scripts/runqemu: avoid overridden user input for bootparams
Currently runqemu hardcodes the "ip=" kernel boot parameter when configuring QEMU to use tap or slirp networking. This makes the guest system to have a network interface pre-configured by kernel and causes systemd to fail renaming the interface to whatever pleases it: Feb 21 10:10:20 intel-corei7-64 systemd-udevd[201]: Error changing net interface name 'eth0' to 'enp0s3': Device or resource busy, Always append user input for kernel boot params after the ones added by the script. This way user input has priority over runqemu's default params. Signed-off-by: Dmitry Rozhkov <dmitry.rozhkov@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
