This patch didn't work for me, git and patch asserted that it's malformed:
-
samuel at S-Stirtzel-Linux:/var/oe-core/setup-scripts/sources/openembedded-core$
git apply /home/samuel/Downloads/runqemu-initial.diff
fatal: patch with only garbage at line 3
samuel at S-Stirtzel-Linux:/var/oe-core/setup-scripts/sources/openembedded-core$
patch -p0 < /home/samuel/Downloads/runqemu-initial.diff
patching file scripts/runqemu-internal
patch: **** malformed patch at line 6: "qemuarmv6" -o "$MACHINE" = "qemuarm

After I got this done, executing runqemu shows this error:
-

Ext3 works with the script (reverted the patch), but it seems that i
can't connect my machine (host) to the internet as long as QEMU runs.
Can't try if the guest can access the internet or communicate with the
host since it looks like systemd patches broke some init related
stuff.
