Hello,

 

I’m trying to setup oVirt for the first time using hosted engine. This is on a Dell PowerEdge R720 (512GB RAM), with 2 10G interfaces (connected to regular access ports on the switch, DHCP), and using external iSCSI storage. This is on CentOS 7.2 (latest) with the 4.5 kernel from EPEL. Here’s the main error I’m getting at the end of setup:

 

RuntimeError: Failed to setup networks {'ovirtmgmt': {'nic': 'p1p1', 'bootproto': 'dhcp', 'blockingdhcp': True, 'defaultRoute': True}}. Error code: "29" message: "Determining IP information for ovirtmgmt... failed; no link present.  Check cable?"



This message comes from vdsm, can you please attach vdsm log?


 

 

Here is what that interface ‘p1p1’ looks like:

 

[root@labvmhostt01 ovirt-hosted-engine-setup]# cat /etc/sysconfig/network-scripts/ifcfg-p1p1

# Generated by dracut initrd

DEVICE="p1p1"

ONBOOT=yes

UUID="9d2666a5-9b72-4f9e-b4e9-4bfb6ad9b263"

IPV6INIT=no

BOOTPROTO=dhcp

DEFROUTE=yes

HWADDR="a0:36:9f:33:39:e8"

TYPE=Ethernet

NAME="p1p1"

PERSISTENT_DHCLIENT=1

NM_CONTROLLED=no

LINKDELAY=10

 

Note that I had added ‘linkdelay=10’ because that interface takes a while to come up. Without it, an ‘ifup p1p1’ will generate that same error about “no link present. Check cable?”. It works after a second ‘ifup p1p1’. With the linkdelay option it works right away. I wonder if that’s related.  From /var/log/messages:


You are correct, it is related.
VDSM takes over the ifcfg configuration of the interfaces it manages and writes its own settings (overwriting the existing config after backing it up).
At the moment, we do not support the LINKDELAY option.

As an workaround, you could use a VDSM before_ifcfg_write hook to add this parameter for the specific nic.

Please open a bug on this so we can track it.

Thanks,
Edy.

I’m attaching the setup log file. The physical interface p1p1 is indeed stable once up. Any help would be appreciated!

 

Thanks,

Daniel
