hi everyone


i have a problem in adding host to ovirt manager. infact i want to add
ovirt manager as a hypervisor node (host).
if you see my snapshot  some errors will be bold:

cannot validate hostname settings reason resolved host does not match
any of the local addresses
yum cannot queue package tuned; no packages  available to install
failed to execute package installation
failure code 1 during ssh session root at internal


os: centos6.4
ovirt engine : 3.2
server : hp dl580 g7
hostname: main-ovirt.nocrservices.org
