Step 7: Add a manual host entry to the /etc/hosts file (on the Red Hat Enterprise Linux host) for the

RHEV-M server to enable vdsm and other services to connect properly to the host (if not

using DNS services).

10.0.0.1 server1.example.com rhev-manager.server1.example.com

For example:

172.30.40.147 host2-1.lab.mtl.com rhev-manager.host2-1.lab.mtl.com

Step 8: Open firewall ports.

The following commands will remove existing firewall rules and add the required ports by

RHEV-M to the iptables rules.

[root@host3]# iptables --flush

[root@host3]# iptables --append INPUT -m state --state ESTABLISHED,RELATED

-j ACCEPT

[root@host3]# iptables --append INPUT -p icmp -j ACCEPT

[root@host3]# iptables --append INPUT -i lo -j ACCEPT

[root@host3]# iptables --append INPUT -p tcp --dport 22 -j ACCEPT

[root@host3]# iptables --append INPUT -p tcp --dport 16514 -j ACCEPT

[root@host3]# iptables --append INPUT -p tcp --dport 54321 -j ACCEPT

[root@host3]# iptables --append INPUT -p tcp -m multiport --dports 5634:6166

-j ACCEPT

[root@host3]# iptables --append INPUT -p tcp -m multiport --dports

49152:49216 -j ACCEPT

[root@host3]# iptables --append INPUT -j REJECT --reject-with icmp-host-

prohibited

[root@host3]# iptables --append FORWARD -m physdev ! --physdev-is-bridged -j

REJECT --reject-with icmp-host-prohibited

[root@host3]# /etc/init.d/iptables save

[root@host3]# chkconfig iptables on

[root@host3]# service iptables restart

Step 9: RHEV-M makes use of sudo to perform operations as root on the host. The default

configuration stored in /etc/sudoers contains values to allow this. To configure sudo access,

add the following entry to /etc/sudoers.

root ALL=(ALL) ALL

Step 10: Enable SSH access for root user. Add the following entry in /etc/ssh/sshd_config.

1 2 ... 15 16 17 18 19 20 21 22 23 24 25 ... 50 51
