I currently set CONNECTED_MODE outside of ovirt using Puppet, and have no tried this with 3.5 as yet to upgrade. Having full 65K MTU is key on my IB fabric and using iSER benefits from maintaining that value. IIRC vdsm controls all interfaces starting from 3.5 (unified persistence). All the interfaces that were configured via the oVirt engine or vdsm (those will have a '#generated by vdsm' kind of header. So writing to them is pointless due to reboots. So a hook in /usr/libexec/vdsm/hooks/before_vdsm_start might be the best choice. An educated guess would be: Yes, that's a good choice of hooking point. If you are configuring them with oVirt, you could also make a after_network_setup hook that did as below. #!/bin/sh echo connected /sys/class/net/ib0/mode echo connected /sys/class/net/ib1/mode Markus - Trey On Oct 19, 2014 10:11 AM, Arman Khalatyan arm2...@gmail.com wrote: Hi, I need to add following line in the hosts ifcfg-ib0 interface: --- CONNECTED_MODE=yes MTU=65520 IPV6INIT=no --- From the web Interface I can change only custom MTU.
