That was the wrong thing to change.  The port there is the connection to
OpenIPMI's VM interface, which is 9002.  623 is the port you use for
ipmitool.

Set the port back to 9002 in the command line above, run ipmi_sim, leave
ipmi_sim running, and run qemu from the command line.  That way it has
something to connect to.

Also, what branch in the qemu ipmi repository are you using?  The 2.3
one may have an issue.  The 2.2 one should work ok.

No, that's irrelevant for this.
