kata 3.0 is now supported rootless. But when I use nerdctl + kata in rootless, it raised error: failed to create shim task: could not create VMM user: exit status 1: unknown

kata 3.0 is now supported rootless. I followed the instruction to set the rootless for kata, and followed the doc to set the rootless for nerdctl. However, when I tried to run the following command to create a container in rootless:

nerdctl run -it --runtime io.containerd.kata.v2 ubuntu:20.04 sh

It raised error as:

FATA[0000] failed to create shim task: could not create VMM user: exit status 1: unknown

So how to fix this problem? Thank you.
