Hi,
we are running a RHV 4.1 installation which is working fine except one issue:
We have a Network which is only used for fencing(power Management via ilo), each host has an interface with this network and a custom ip, for this to work we need a few custom routes. At the moment we add the new routes via a plain route file under /etc/sysconfig/network-scripts/, but the engine flags this interface then as out-of-sync.
How can we persist those changes across reboots and still be able to add new devices via the UI ?
This looked promising but isnt working: https://ovirt.org/develop/release-management/features/network/networkreloade...
Thanks for any Help :) ____
I never used this feature, but I remember that you can specify in vdsm.conf a list of interfaces that you want vdsm not to manage so that you can configure them manually for your specific targets Eg. on my 4.2.7 host I see this in the plain vdsm.conf.rpmnew " # Comma-separated list of fnmatch-patterns for host nics to be hidden # from vdsm. # hidden_nics = w*,usb* # Comma-separated list of fnmatch-patterns for host bonds to be hidden # from vdsm. # hidden_bonds = # Comma-separated list of fnmatch-patterns for host vlans to be hidden # from vdsm. vlan names must be in the format "dev.VLANID" (e.g. # eth0.100, em1.20, eth2.200). vlans with alternative names must be # hidden from vdsm (e.g. eth0.10-fcoe, em1.myvlan100, vlan200) # hidden_vlans = " In case you apply anything, I think you had better create a file in /etc/vdsm/vdsm.conf.d, such as 50_unmanaged_nics.conf containing hidden_nics = eth3 to be preserved across updates. With this parameter you shouldn't see the interface listed in setup host networks of the host gui. The concept came out last year when I posted a question related to OVN and Marcin Mirecki kindly answered about it. See here and the whole thread: https://lists.ovirt.org/pipermail/users/2017-February/079772.html Marcin, possibly you can add something for this particular need? HIH, Gianluca
