Problem with the networking layer not working

[AntoineM]

Hello everyone,

I have an online XenServer hosted by OVH, with several virtual machines on it.
I've setup a CentOS7 system following the guide provided on http://guide.ovh.com/BridgeClient. OVH gave me a Failover IP and an automatically generated MAC.

The problem I'm having is the network layer which doesn't work and the eth0 interface doesn't go up.

The command "systemctl status network.service" gives me the folowing error message:
Failed to start LSB: Bring up/down networking

This is what my ifcfg-eth0 file looks like:

Code: Select all

DEVICE=eth0
BOOTPROTO=nonre
ONBOOT=yes
USERCTL=no
IPV6INIT=no
PEERDNS=yes
TYPE=Ethernet
NETMASK=255.255.255.255
IPADDR=87.98.170.164
GATEWAY=37.59.0.254
ARP=yes
HWADDR=02:00:00:DF:D6:FE

I've stripped out everything related to IPv6 in it.


My route-eth0 is the following:

Code: Select all

37.59.0.254 dev eth0
default via 37.59.0.254 dev eth0

"ifconfig -a" doesn't give me the IP address.
There are lots of RX packets, part of them dropped, but no RX errors
There are lots of TX packets, but no drops or errors.

Also, the "route" or "ip show route" doesn't give anything, although the gateway is defined in route-eth0 and ifcfg-eth0

Anyone knows what this might be related to and how it might be solved ?


Thank you,
Antoine

You need to talk to OVH for help. Not only do they supply the majority of their systems with non-CentOS kernels but they also have the weirdest non-standard network setup that anyone has ever seen. Only they can help you I'm afraid.

Hello Trevor,

I've tried opening a case with them. After several weeks of them asking me for info, they finally told me this is a software issue and they don't cover those.

I'm kind of lost on what to do next!
