[ovirt-users] ovirtmgmt network out of sync

Thu May 18 07:30:13 UTC 2017

Yes, thanks)

Engine complains about the bootproto , he is expecting dhcp, but you
configured it manually with static.
Was it dhcp before the upgrade?

There is an option to change it back to dhcp, restart network service and
this should be fixed. But i don't think that this is what you looking for
as you may loose connectivity for few seconds.
I don't think there is another option to sync the network while a running
VM using it, at least not that i'm aware of.

Maybe Dan or Yevgeny will have some insight.

Just to be clear, you upgraded both engine and vdsm?
I'm a bit confused from your ifcfg files, you said you created the
ifcfg-ovirtmgmt manually after the upgrade, but it was generated by an
older vdsm version  4.17.23.2-0.el7.centos, and the physical interface
generated with a newer vdsm version 4.19.10.1-1.el7.centos.

I don't think we need the whole /vdsm , only the relevant vdsm log from the
upgrade time, can you locate it?
and the supervdsm.log as well.

Thanks,
