My current configuration is

DISTRO_FEATURES:append = "opengl x11 vulkan"

This wasn't enough for libvulkan.so.* to be installed or vulkaninfo to work. Only the simple weston egl examples work.

I also tried adding virtio-experimental to VULKAN_DRIVERS in mesa.inc, didn't help either.

You need to check the Mesa recipe to see how the build options are defined

mesa builds vulkan support, if you add 'vulkan' to DISTRO_FEATURES. If you need to, you can add additional drivers with a line like this to a mesa_%.bbappend:

VULKAN_DRIVERS:append = ",foo,bar"
