[ovirt-users] CentOS 7 + oVirt 3.5 + OpenVPN

[Phil Daws]

Hello:

have installed oVirt 3.5 VDSM on a CentOS 7 node and then OpenVPN.  The problem I have is that when I start OpenVPN I receive the message:

Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip link set dev tun0 up mtu 1500
Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip addr add dev tun0 192.168.124.200/25 broadcast 192.168.124.255
Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip route add 192.168.0.0/16 via 192.168.124.1
Oct 18 13:29:50 kvm01 openvpn[4159]: ERROR: Linux route add command failed: external program exited with error status: 2

and if I run the route command manually:

[root at kvm01 sysconfig]# /usr/sbin/ip route add 192.168.0.0/16 via 192.168.124.1
RTNETLINK answers: No such process

It would appear the tunnel is up:

[root at kvm01 sysconfig]# ip add ls

Any thoughts as to why the route will not work ? Rationale for this approach is its a cloud server and wish to use a private network to reach the install VMs on that node.

Thanks, Phil
