I used the docker-rootful.yml to build up the vm with the command below, against which my docker context is running.

limactl start ~/Downloads/docker-rootful.yaml --name docker --tty=false

And I run pull ubuntu, but the error message came up often. Not always, sometimes it worked, sometimes this error raised.

(base) sss@sss-mac test1 % docker pull ubuntu
Using default tag: latest
Error response from daemon: Get "<https://registry-1.docker.io/v2/>": dial tcp: lookup registry-1.docker.io on 127.0.0.53:53: read udp 127.0.0.1:41836->127.0.0.53:53: i/o timeout

If I ever successfully pulled it and ran it, I ran things below and I always get numerous ign message and never finish. It first successfully "get" a couple things, and then "ign" the rest.
I verified that the problem doesn't exist when I ran the same thing in engine hosted by docker-desktop.
