Hi Netbulae,
I tried to reproduce on a fresh install of 3.5 rc1 on Centos 6.5 and it works correctly finding jboss under /usr/share/ovirt-engine-jboss-as

Are you able to reproduce it or can you provide more details about that?

Just tried it again, do we have the same rpm's?

The required modification has been merged the 23th of May so it should be also in your RPMS. http://gerrit.ovirt.org/#/c/28064/

Can you please check the content of:
/etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf

I have the same RPM's but the config still points to the old path. This can be because I installed/upgraded multiple times along the way.

cat /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf
[environment:default]
OVESETUP_CONFIG/jbossHome=str:/usr/share/ovirt-engine-jboss-as

But I did a yum remove and it was gone:

cat /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf
cat: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf: No such file or directory

Then I reinstalled the rpm's and it's still the old path and setup still fails:

cat /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf
[environment:default]
OVESETUP_CONFIG/jbossHome=str:/usr/share/ovirt-engine-jboss-as

Sorry I was looking crooked, the path in "/etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf" is and was correct but it appears to be ignored...

engine-setup --config=/var/lib/ovirt-engine/setup/answers/20140818114004-setup.conf

[ ERROR ] Failed to execute stage 'Misc configuration': Cannot find Jboss at /usr/share/jboss-as

I checked the answers file but it's not getting that path from there.

Weird, without the answers file setup works without the error. 

But the answer file doesn't have a jboss parameter at all:

# action=setup

OVESETUP_APACHE/configureRootRedirection=bool:True
OVESETUP_APACHE/configureSsl=bool:True
OVESETUP_CONFIG/websocketProxyConfig=bool:True

So I did a fresh install without answer file and there is still no jboss parameter in there. Then I did engine-cleanup and engine-setup with the latest answer file and it fails again.

I think "OVESETUP_CONFIG/jbossHome=str:/usr/share/ovirt-engine-jboss-as" has to be added to the answer file generated by setup to fix this.

The problem is just there: you have to distinct CLI options on engine-setup
    --config=file
        Load configuration files.
    --config-append=file
        Load extra configuration files or answer file.

The first one loads a custom configuration file from a custom location instead of loading the default configuration, the second one instead appends options from an extra configuration file or from an answer file to the default configuration.
Answer file should just be used with --config-append because it's not a complete configuration containing just response to interactive questions for unattended setups.

I'll close this cause I think that the problem is just there, please reopen if it happens also using  --config-append=

I was hitting the very same bug on RHEL 6.6 until I found Simone's explanation. Thank you so much! It's very misleading, I think the --config option should be renamed. After I found it in --help I did not search for anything else because I've thought this is what I want. At least there should be BIG PHAT warning in the help screen that this is most likely what you don't want.

I vote from removing this option from the help screen and documentation so only experienced users or QAs can use that. :-)

Ran into the same problem on CentOS 6.6 after uninstalling and reinstalling oVirt.
This was the output of engine-setup:

[ ERROR ] Failed to execute stage 'Misc configuration': Cannot find Jboss at /usr/share/jboss-as
[ INFO  ] Yum Performing yum transaction rollback
[ INFO  ] Stage: Clean up
          Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20150116104457-dmh3y7.log
[ INFO  ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20150116104718-setup.conf'

Got the following error: Failed to execute stage 'Misc configuration': Cannot find Jboss at /usr/share/jboss-as

/usr/share/jboss-as indeed didn't exist but /usr/share/ovirt-engine-jboss-as did.

So as Simone and Netbulae pointed out, I added this line:
OVESETUP_CONFIG/jbossHome=str:/usr/share/ovirt-engine-jboss-as

to the answer file: /var/lib/ovirt-engine/setup/answers/20150116104718-setup.conf
and I reran engine-setup as follows:
# engine-setup --config-append=/var/lib/ovirt-engine/setup/answers/20150116104718-setup.conf

This seemed to work fine :)
