I would like to run a domain controller which manages 4 server instances and I have 2 vms (eg. 192.168.0.2, 192.168.0.3)

VM1: (192.168.0.2)

   DC

   SEL-1

   SEL-2

VM2: (192.168.0.3)

   SEL-3

   SEL-4

I have created 2 users in the ManagementRealm in the Domain Controller

- selmain

- selremote

and I have configured the host.xml

VM1: (192.168.0.2)

This configuration works fine when I start the DC and HC as follows

domain.bat -Djboss.domain.master.address.management=192.168.0.2 -Djboss.bind.address.management=192.168.0.2 -Djboss.bind.address=192.168.0.2
domain.bat -Djboss.domain.master.address.management=192.168.0.2 -Djboss.bind.address.management=192.168.0.3 -Djboss.bind.address=192.168.0.3

Note that in the 2nd host.xml the name of the file is NOT the username of the DC user which will handle the HC

<host name="SEL" xmlns="urn:jboss:domain:1.3">

but

    <domain-controller>
       <remote host="${jboss.domain.master.address}" port="${jboss.domain.master.port:9999}" username="selremote" security-realm="ManagementRealm"/>
    </domain-controller>

I set the username

However, on the DC side I can ONLY see one way of setting the username to be used for the LOCAL HC  and that is in the name of the hose

<host name="selmain" xmlns="urn:jboss:domain:1.3">

Note here I have left the default

    <domain-controller>
       <local/>
       <!-- Alternative remote domain controller configuration with a host and port -->
       <!-- <remote host="${jboss.domain.master.address}" port="${jboss.domain.master.port:9999}" security-realm="ManagementRealm"/> -->
    </domain-controller>

What is the way to set a different host name in the DC side? And how to configure the management user name in that case?
