From 1a8e44a89f1976e06300393337f78d561f95b339 Mon Sep 17 00:00:00 2001 From: Andrey Gruzdev Date: Thu, 1 Apr 2021 12:22:24 +0300 Subject: migration: Inhibit virtio-balloon for the duration of background snapshot The same thing as for incoming postcopy - we cannot deal with concurrent RAM discards when using background snapshot feature in outgoing migration.
