Ok, but this means that these kind of customization are to be done only
after I have also installed the engine and added the node to it.
And not in the preliminary phase where I have only installed the ovirt node
OS from the iso and I'm accessing it from http://host_ip_addr:9090 cockpit
interface, correct?
Thanks,

Hello,

you can specify more bondings options by selecting Bonding Mode
"custom" and passing "miimon=100 updelay=0 downdelay=0 mode=802.3ad
lacp_rate=1" there.

[ovirt-users] oVirt node and bonding options cutomizations

2017-09-08 Thread Gianluca Cecchi 
Hello,
when using CentOS as OS for hypervisor and mode=4 for bonding (802.3ad) in
the past I had to use lacp_rate=1 (aka fast), because I noticed problems
with the default lacp_rate=0 parameter.
Now I'm testing an oVirt node and I see that into the graphical interface
there are the options to set mode, link up and down delays, but not the
lacp_rate option.

It is a different environment from the one where I had to modify it, so I
will start with the default value and see if I get any problems again.

Now the ifcfg-bond0 file created at oVirt node level by the web mgmt
interface contains:

BONDING_OPTS="miimon=100 updelay=0 downdelay=0 mode=802.3ad"

Would I be able to modify it in case of need and have it persistent across
reboot, something like this:

BONDING_OPTS="miimon=100 updelay=0 downdelay=0 mode=802.3ad lacp_rate=1"

?

Thanks in advance,
Gianluca
