Description of problem:

In https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.5/html/Installation_Guide/Subscribing_to_the_Required_Entitlements.html

~~~
Red Hat Enterprise Linux 7:

# subscription-manager repos --enable=rhel-7-server-rpms
# subscription-manager repos --enable=rhel-7-server-supplementary-rpms
# subscription-manager repos --enable=rhel-7-server-rhev-mgmt-agent-rpms
~~~

but in local Installation Guide from 3.5.6 there's:

~~~
Red Hat Enterprise Linux 7

    rhel-7-server-rpms
    rhel-7-server-supplementary-rpms
    rhel-7-server-optional-rpms
    rhel-7-server-rhev-mgmt-agent-rpms 

For more information on subscribing to these channels using Subscription Manager, refer to Section 2.3, “Subscribing to the Required Channels Using Subscription Manager”.

I didn't have optional and I could not update the host:
