-- Starting Minishift VM ..... FAIL E0321 11:29:07.578030

Error starting the VM: Error creating the VM. Error with pre-create check: "Error detecting VBox version: exit status 126"  

I got the above error while firing up Minishift to run through Rafaele Benevides Istio Tutorial for Red Hat Developers, which you can find here:  https://github.com/redhat-developer-demos/istio-tutorial

The error is related to an incomplete uninstall of Virtual Box.  The solution is simple: download Virtual Box and run the Uninstall Tool.

How to let Arquillian know that JBoss is running on localhost

Just add the following to the configuration section:

${arquillian.wildfly.host:localhost}

My complete file was:

   <container qualifier="jboss" default="true">
        <!-- By default, Arquillian will use the JBOSS_HOME environment variable to find the JBoss EAP installation.
             If you prefer not to define the JBOSS_HOME environment variable, alternatively you can uncomment the
             following `jbossHome` property and replace EAP_HOME with the path to your JBoss EAP installation. -->
        <configuration>
            <property name="managementAddress">${arquillian.wildfly.host:localhost}</property>
            <property name="jbossHome">/Users/jeremydavis/Workspace/summit/jboss-eap-7.1</property>
        </configuration>
    </container>

Failed to link org/wildfly/swarm/container/runtime/RuntimeServer

I got the following error running the WildFly Swarm jaxrs-cdi example:

The fix was pretty simple: rebuild WildFly Swarm itself.  After a quick mvn clean install everything was up and running.

I was recently doing some web stuff on my laptop for the first time in a while. I could pull up the "It Works!" page, but nothing else.
This Apple forum post solved it.
Blogged here to help search results :)
