[libvirt PATCH] Send event on persistent config modification

From: Efim Shevrin <efim.shevrin(a)virtuozzo.com&gt; Date: Tue, 10 May 2022 17:03:11 +0300 Subject: [PATCH] Send event on persistent config modification Libvirt is not sending events in case of a device update, thus any services listening to events are unaware of the changes.This patch suggests to send event in case of a persistent config modification, it should keep subscribed services in sync with VM configuration.
