logs from host and engine

Description of problem:
Hosted engine deployment fails due to a failure to add the hosted-engine VM to the setup.


Version-Release number of selected component (if applicable):

ovirt-hosted-engine-setup-1.3.0-0.0.master.20150518075146.gitdd9741f.el7.noarch
vdsm-4.17.0-822.git9b11a18.el7.noarch
ovirt-engine-3.6.0-0.0.master.20150616113618.git046b36e.el7.centos.noarch


How reproducible:
Always

**Need to add hook under /usr/libexec/vdsm/hooks/after_get_caps/ to add 'pc-i440fx-rhel7.1.0' to the supported emulated machines (credit to Simone Tiraboschi for the hook):


!/usr/bin/python
 
import hooking
 
if __name__ == '__main__':
    caps = hooking.read_json()
    caps['emulatedMachines'].append('pc-i440fx-rhel7.1.0')
    hooking.write_json(caps)



Steps to Reproduce:
1. Deploy hosted-engine (I used FC)
2. 
3.


Actual results:
Deployment fails, the hosted-engine VM cannot be added to the setup:
