OLVM: KVM Host is Marked as "Host has to be reinstalled."

Hello,
on OLVM 4.4.10.7, when selecting an host, I get in the below
pane the exclamation mark and aside it the phrase:

Host needs to be reinstalled as important configuration changes were
applied on it

Where to get more information about what it thanks has changed?
Could it be a change in bonding mode to generate this kind of message?

After reinstallation, do we need to re-configure N/W bonding, storage etc?

Thanks and regards,

Omi
