# Boot salmanoff-image with eth0 bridged onto the host lab LAN (10.42.0.0/24).
|
|
#
|
|
# Prerequisites on the host:
|
|
# 1. A Linux bridge (default: br-smo) whose ports include the NIC on 10.42.0.0/24.
|
|
# 2. /etc/qemu/bridge.conf containing: allow br-smo
|
|
# 3. qemu-oe-bridge-helper allowed (setuid or root via sudo policy).
|
|
#
|
|
# Usage (from build/ after sourcing init-build-env):
|
|
# ../layers/meta-salmanoff/scripts/runqemu-salmanoff-bridge
|
|
# ../layers/meta-salmanoff/scripts/runqemu-salmanoff-bridge br-lab
|
|
# ../layers/meta-salmanoff/scripts/runqemu-salmanoff-bridge br-smo 4096
|
|
#
|
|
# Guest eth0 is configured statically as 10.42.0.16/24 via init-ifupdown.
|
|
# Default RAM is 2G: Mesa Rusticl/llvmpipe (clinfo, Salmanoff OpenCL) OOMs at 256M.
