[ovirt-users] Can't add logical network

[Maxence Sartiaux]

Okay, i found a workaround.

- Create empty ifcfg-lan on all hosts (touch /etc/sysconfig/network-
scripts/ifcfg-lan)
- Assign the bridge to the bond (Ovirt only add MTU=1500 in the file)
- Unassign the bridge (Ovirt rewrite the bond configuration files)
- Re-assign the bridge on the bond
- yay it work !
