Uh yes.
I have figured out the problem with importing buffers across vgem/vkms.
It's intentionally blocked by kernel here:

Hi Daniel,
May I know what's the requirement for adding render node support to a
"gpu"? Why we just export render node for every drm devices?
I read document here
https://www.kernel.org/doc/html/v4.8/gpu/drm-uapi.html#render-nodes
and it seems render node allow multiple unprivileged clients

We have virtgpu driver that exports a render node even when virgl is
not supported.

Some libraries including Mesa and virglrenderer require a render node to
fully function. By adding a render node to vkms those libraries will
work properly, supporting use cases like running crosvm with virgl GPU
support via llvmpipe on a headless virtual machine.
