Support on Terraform VM Creation(KVM)

Dear Team,

I have used the below attached tutorial to create a VM using terraform. Even though I completed all the steps without any errors I cannot be able to login the created VM, it says “Login incorrect” . Kindly assist me with this problem.
I am looking forward to your support.

With Regards,
