I have a small test environment, where I am trying to work out the detail of configuring ovirt + gluster as our main customer support environment. All boxes running Scientific Linux 6.5 and ovirt 3.4 and glusterfs 3.5:

mgr1 : ovirt-engine installed and vdsm-gluster
vmhost1 : main vm server, added to mgr1 as host
vmhost2 : second vm server, add to mgr1 as host
strg1 : first gluster storage server
strg2 : second gluster storage server

mgr1 is an old box, hardware does not support virtualization
vmhost1 and vmhost2 have full vt capability
strg1 and strg2 hardware does not support virtualization

In the past, if I have created a gluster only ovirt-engine install, I have been able to add strg1 and strg2 as hosts. Is there any way I can use mgr1 to manage both vm hosts and storage hosts, and add strg1 and strg2 to mgr1 as hosts. At the moment, I get the following error:
2014-04-22 10:27:37 DEBUG otopi.ovirt_host_deploy.hardware hardware._isVirtualizationEnabled:186 virtualization support GenuineIntel (cpu: False, bios: True)
2014-04-22 10:27:37 DEBUG otopi.ovirt_host_deploy.hardware hardware.detect:202 Hardware supports virtualization

Many thanks
