The reason is that the jboss rpm installs the files in
/usr/share/jboss-as, owned by the root:jboss-as, so a non privileged
user will not have permission to write to those directories.

Stephen, what I suggested you to do is to leave the installation of the
application server in the /home/satimis/jboss-as directory and then
modify the /home/satimis/.m2/settings.xml file. It should read as follows:

<settings
  xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <activeProfiles>
    <activeProfile>oVirt</activeProfile>
  </activeProfiles>

  <profiles>
    <profile>
      <id>oVirt</id>
      <properties>
        <jbossHome>/home/satimis/jboss-as</jbossHome>
      </properties>
    </profile>
  </profiles>

</settings>

Also you don't need to start the jboss-as service, as ovirt doesn't use
it. In a development environment you just go to
/home/satimis/jboss-as/bin and run standalone.sh.

Also make sure that you own the /home/satimis/jboss-as directory:

sudo chown --recursive satimis:satimis /home/satimis/jboss-as

Let me insist that if the build runs correctly what you will have is an
environment that you can use for development, it is not suitable or
designed for using ovirt. If what you want to do is test ovirt from the
user point of view then I strongly recommend that you use the prebuilt RPMs.
