Couldn't connect VM using SSH

[ghost]

I have installed UTM on my Mac M1 and created a virtual machine using the RHEL7.6 ISO image.
The installation of the virtual machine was successful, but when I try to connect to the created virtual machine from my local machine using port forwarding, I get the following error and it fails.

$ ssh root@localhost
kex_exchange_identification: read: Connection has been reset by peer

I would like to know how to solve this.

[Environment]
OS: macOS Big Sur
Architecture M1
UTM Version: 2.0.28 (28)

try setting up port forwarding to a different port than ssh (i. e. port 4321), and set up sshd in RHEL to listen on that port, then try this
$ ssh root@localhost -p <port>

Hi
Thank you for your comment.

I have configured port 4321 on the local PC to be port forwarded to port 22 on the virtual machine.

However, I get the same error.
$ ssh -v root@localhost -p 4321

Port 22 is being listened on the virtual machine.

Where else should I check?
