Hi Kasturi,
Yes the ‘/var/lib/glusterd/virt’ was missing from my system.
I’m running ovirt on a RHEL - 7 - 3.1611.el7.centos on a physical machine.
The mistake is due to inexperience on my part. I stated earlier that I 
completely removed glusterfs and reinstalled it in order to recreate 
the ‘/var/lib/glusterd/virt’. The way I was uninstalling and 
reinstalling gluster must have been incorrect.
I ran ‘rpm -qa |grep gluster’ to get a list of the gluster components 
installed. I then proceeded to remove each one on the list. Then I ran 
a ‘yum install glusterfs* vdsm-gluster’ since I’m not sure which rpm 
provides the ‘/var/lib/glusterd/virt’ file.  I’m not sure if this 
installs too many components but after that, 
the ‘/var/lib/glusterd/virt’ was present on my the system. I was able 
to proceed normally after that.
Thanks for taking the time to engage in my question,
Joel
Good to know that it works :-)

I though I would try something different so I removed the key
    group and value virt when creating the volumes. I was able to
    create the volumes. I stopped the data volume. I then tried to
    set the volume group by issuing a "gluster volume data group virt"
Still get "unable to open file '/var/lib/gluster/Virt'. Error: No
    such file or directory.
I don't know if I should continue with the setup until I can set
    this value.
Please let me know if I can provide some logs to identify the issue.
Thanks for your help,
Joel

Thanks for the reply.
The file is empty. I created the file by issuing a "touch
        /var/lib/glusterd/groups/virt"
The first time I attempted to set the group volume, the error
        was that the file was missing. I read a bug report that
        advised to remove and reinstall the gluster package in order
        to properly recreate the file. Since that did not work, I
        created it manually.
Thank you,
Joel
Hi Joel,
Do you have this file present on the system ? This file will
    be present when glusterfs is installed. I would like to first
    understand how is it missing on your system? The error is because
    i see that you do not have the file present there. Can you please
    paste output of "ls -l /var/lib/glusterd/groups/virt" ?
Thanks

Hello ovirt users,
First off all, thanks for your work. I've been using the
            software for a few months and the experience has been great.
I'm having a hard time trying to set the group on a
            glusterfs volume

                  Do you have this file present on the system ? This
