Description Martin Tessun 2015-06-22 10:03:38 UTC

Description of problem:
Some mandatory interfaces for rhevm network are saves with "ONBOOT=no" when using unified network persistence

Version-Release number of selected component (if applicable):
vdsm-4.16*

How reproducible:
always

Steps to Reproduce:
1. Create a VLAN tagged rhevm-network
2. Create a VM network (also VLAN tagged)
3. In the host create the bond and assign the rhevm network and the VM network to it

Actual results:
The eth-interfaces and the bond-interface that is needed for the rhevm-VLAN is set to ONBOOT=no


Expected results:
The eth-interfaces and the bond that is needed for the rhevm network should stay in ONBOOT=yes

Additional info:

Assuming the following setup:

eth0 + eth1 ==> bond0 ==> bond0.100 ==> rhevm (bridge)
                      ||
                      ==> bond0.200 ==> vm_network (bridge)


Then vdsm first creates the rhevm-network correct and overwrites the config when creating the vm_network files:

As can be seen the later configured vm_network rewrites the configs for bond0, eth0 and eth1, putting a "ONBOOT=no" in there now. This should not be the case, as eth0,1 and bond0 are needed by the rhevm network and should therefore stay in the previously generated config with "ONBOOT=yes".

Comment 2 Fabian Deutsch 2015-06-22 12:15:03 UTC

On what kind of host did you see this issue - RHEL-H or RHEV-H?

Comment 3 Martin Tessun 2015-06-22 12:17:54 UTC

Hi Fabian,

sorry, forgot to mention that. This issue has been observed on a RHEL-H system.

Comment 5 Ido Barkan 2015-07-12 19:15:42 UTC

the work that is being done for https://bugzilla.redhat.com/show_bug.cgi?id=1203422 will solve this bug ,as from 3.5.4 VDSM will create all ifcfg files with ONBOOT=yes.

Restarted network service with success and rebooted server with success, all network configuration kept. Server is UP in rhev-M.
