I created my own AMI & when I start my instance sshd is not getting started. What might be the problem?
Please find below the system log snippet

The problem was due to selinux. Once I disabled selinux during boot up by providing selinux=0 as argument in GRUB for kernel field, the machine booted with sshd service started and I’m able to connect to it.
