Setting up the RHEL operating system for
the manager
Prior to starting the installation of RHEV-M, please make sure all the prerequisites are met
as explained in Chapter 1 , An Overview of Red Hat Enterprise Virtualization .
Consider the following when setting up RHEL OS for RHEV-M:
• Install Red Hat Enterprise Linux 6 with latest minor update of 5, and during pack-
age selection step, select minimal or basic server as an option. Don't select any cus-
tom package.
• The hostname should be set to FQDN.
• Set up basic networking; use of static IP is recommended for your manager with a
default gateway and primary and secondary DNS client configured.
• SELinux and iptables are enabled by default as part of the operating system install-
ation. For more security, it's highly recommended to keep it on.
To disable SELinux on Red Hat Enterprise Linux, please run the following command as the
root user:
# setenforce Permissive
This command will switch off SELinux enforcement temporarily until the machine is re-
booted. If you would like to permanently disable it, edit /etc/sysconfig/selinux
and enter SELINUX=disabled .
