weston-ivi-shell-user-interface segfaults with qemu, yocto, virgl, aarch64 and ivi shell

Weston version is 9.0.0.

I try to run weston with virgl on yocto on qemu, x86 host, aarch64 guest. I use hmi controller in weston ini. It works under normal desktop shell, but if I switch to ivi shell then weston-ivi-shell-user-interface ( and some other weston test apps) start crashing with segfault. This is the callstack:

It looks like the hmi controller never registers itself so the resulting proxy is nullptr.

This is the weston.ini I use:
