How to run each TestNG suite in a separate process?

[Albert Pinto]

My pom.xml defines two TestNG suites as follows:
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19</version>
    <configuration combine.children="override">
      <forkCount>1</forkCount>
      <reuseForks>false</reuseForks>
      <suiteXmlFiles>
        <suiteXmlFile>suite-1.xml</suiteXmlFile>
        <suiteXmlFile>suite-2.xml</suiteXmlFile>
      </suiteXmlFiles>
    </configuration>
  </plugin>
</plugins>

I would like to run each suite in a separate jvm process one after another 
(without overlapping execution). I have tried playing around with different 
parameters but not able to get this working. Is there a way to do this?start 
process P1
run suite-1.xmlstop process P1start process P2run suite-2.xmlstop process P2
