In the past patches like this have been rejected for performance and other reasons. While I don't particularly like requiring sudo access for runqemu, adding the 'slirp' option will allow someone w/o root/sudo to be able to run it. Otherwise, if there is something you can do to make slirp work better (when enabled), that is more likely to be accepted. --Mark > Signed-off-by: Todor Minchev <todor.minc...@linux.intel.com> > --- > meta/conf/machine/include/qemuboot-x86.inc | 1 + > scripts/runqemu | 3 ++- > 2 files changed, 3 insertions(+), 1 deletion(-) > > diff --git a/meta/conf/machine/include/qemuboot-x86.inc > b/meta/conf/machine/include/qemuboot-x86.inc > index 06ac983..0870294 100644 > --- a/meta/conf/machine/include/qemuboot-x86.inc > +++ b/meta/conf/machine/include/qemuboot-x86.inc > @@ -13,3 +13,4 @@ QB_AUDIO_OPT = "-soundhw ac97,es1370" > QB_KERNEL_CMDLINE_APPEND = "vga=0 uvesafb.mode_option=640x480-32 > oprofile.timer=1 uvesafb.task_timeout=-1" > # Add the 'virtio-rng-pci' device otherwise the guest may run out of entropy > QB_OPT_APPEND = "-vga vmware -show-cursor -usb -usbdevice tablet -device > virtio-rng-pci" > +QB_SLIRP_OPT = "-net nic,model=e1000 -net user,hostfwd=tcp::2222-:22" > diff --git a/scripts/runqemu b/scripts/runqemu > index dbe17ab..6952f32 100755 > --- a/scripts/runqemu > +++ b/scripts/runqemu > @@ -542,7 +542,8 @@ class BaseConfig(object): > def check_and_set(self): > """Check configs sanity and set when needed""" > self.validate_paths() > - check_tun() > + if not self.slirp_enabled: > + check_tun() > # Check audio > if self.audio_enabled: > if not self.get('QB_AUDIO_DRV'): > -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
