Hi Roman,
I provided most of the code for the "tz-launcher" program you are
referring to.
I just started a Weston with the FBDev backend, verified that GL
rendering was inactive, and "tz-launcher" worked as expected. It was
on a real device, though ; VMWare may be different.
So in order to help you, my questions will be :
1) Do you see the background ? (gulf sea with some islands)
2) Are you able to run tz-launcher in a reduced mode with this command
(switch to a VT by doing "Ctrl-Alt-F2" e.g.) :
$ tz-launcher /usr/share/applications/weston-terminal.desktop
3) If it segfaults, could you post a backtrace of the following :
$ zypper install gdb
$ gdb tz-launcher
$ run /usr/share/applications/weston-terminal.desktop
(it crashes)
$ bt

Actually, VIGS/YaGL already runs wayland, you can refer to Tizen
IVI emulator, it uses tizen.org <http://tizen.org> QEMU and runs
Tizen IVI image. I'm not sure about Common, I never
actually tried it.

In general, it may be good to re-use some of the specific kernel
configs that are described here also in the Tizen Common kernel:
