I tried to use below command
qemu-system-x86_64 \
-m 4096 \
-smp 2 \
-drive file=noble-server-cloudimg-amd64.img,format=qcow2 \
-net nic -net user,hostfwd=tcp::2222-:22 \
-nographic
Then connected to the image to check ssh configs(/etc/ssh/sshd_config) and updated below line,
PermitRootLogin yes
Other lines we same as below which did not need any changes,
PasswordAuthentication yes
Port 22
