Can't boot poky-tiny in qemu

Can't boot poky-tiny in qemu

I'm trying to come to grips with Yocto and poky and a minimal image so I'm trying to build boot and modify poky-tiny and having no luck booting it in qemu.

I'm following instructions here https://wiki.yoctoproject.org/wiki/Poky-Tiny#Some_information_about_the_running_system but when I run the qemu command nothing happens. I'm a total noob with qemu so I don't even know how to approach figuring out what is wrong.

Any help would be appreciated.

Thanks,
Matt S.

Some additional information, I've been testing with Yocto 1.6 (daisy), I just tried it with 1.5 (dora) and it does better I actually see some output, but it gets stuck in the init script with the repeating messages: 

[    3.379021] Freeing unused kernel memory: 284k freed
/init: line 26: setsid: not found
Console sh exited with 127, respawning...
/init: line 26: setsid: not found

I guess the problem is kernel related. Maybe the kernel configuration 
for linux-yocto-tiny lacks something.

Please open a bug in bugzilla, if convenient.

Thank you, I created a bug in bugzilla, https://bugzilla.yoctoproject.org/show_bug.cgi?id=6353. 

I also tested poky-tiny with Yocto 1.5 and it mostly works, there is a little problem with a missing setsid in busybox that is easily fixed, although there is some discussion on which is the proper way to fix it, I don't know enough about bitbake to weight in.
