've been there! :-D

I mean exactly same issuse you had on Centos, I had on Fedora 19.
Did you disable selinux on nodes? 'cause that's what is causing SSh
connection closing

My setup:

1 engine on vmware  - fedora 19, up-to-date

2 nodes on IBM x series 3650  - fedora 19 based -oVirt Node - 3.0.3 -
1.1.fc19 with nodes beig in glusterfs cluster also.....

Right now, I'm banging my head against "Operation Add-Disk failed to
complete." , message I have got after adding a new virtual machine and try
to addd its disk
