I am using "virtio-9p" --
# Shared file system type:

shared_fs = "virtio-9p"
Then why this warning message - warning msg="The virtiofsd had stopped" name=containerd-shim-v2 pid=1897831 sandbox=ksh source=virtcontainers subsystem=qemu ??
Oh, I had not seen that you had configured 9pfs.
Is that still supported?
In my limited experience, you can get the "virtiofsd has stopped" message when there is some abrupt crash of one of the components, and the socket is closed.

It looks like your qemu stopped right after being started (T07:53:29.231939187Z vs T07:53:28.093652406Z). I think that the qemu logs would help us.
