[ovirt-users] 3.5.1 net config persistence

Hello, There are a number of bugs [1] reported these days about the issue aourd network config of the hosts, when dealing with interfaces manually configured, with bonding and VLANs. These /etc/sysconfig/network-scripts/ifcfg.* files are wiped by vdsm after rebooting. I see that there are people at Redhat working on these, and some cases were reproduced in lab conditions - and some were not. I upgraded 3 DC from 3.4.? to 3.5.1, and faced this issue (lost of every network files) in an non-consistent manner. I finally thought I coped with this problem by adding net_persistence = ifcfg to /etc/vdsm/vdsm.conf and indeed, when restarting vdsmd and the network, files were conserved. It was before I observed that some action [2] lead to /etc/vdsm/vdsm.conf being renamed into /etc/vdsm/vdsm.conf.some_timestamp and the original one replaced by a very short file with no netcfg persistence at all. I didn't identified [2]. That could be : - some actions made by me through the Web UI ? - service vdsmd restart ? - reboots ? I'm sure that some Redhat people know what could be responsible for renaming /etc/vdsm/vdsm.conf into /etc/vdsm/vdsm.conf.some_timestamp, and I wish they are working closely with Dan Kenigsberg and Michael Burman who helped a lot on these issues (or maybe, THEY are the coders responsible for this ?)
