From 726662aee0bc295f6931b7aba1bd68f033e949aa Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Thu, 10 Aug 2023 16:08:18 +0200 Subject: [PATCH 3/7] vdpa: use first queue SVQ state for CVQ default MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Eugenio Pérez RH-MergeRequest: 199: CVQ migration support RH-Jira: RHEL-923 RH-Acked-by: Jason Wang RH-Acked-by: Cindy Lu RH-Commit: [3/7] 5c98f11b5080552a62c8e37ff2c23339455b7b86 (eperezmartin/qemu-kvm) Previous to this patch the only way CVQ would be shadowed is if it does support to isolate CVQ group or if all vqs were shadowed from the beginning. The second condition was checked at the beginning, and no more configuration was done. After this series we need to check if data queues are shadowed because they are in the middle of the migration. As checking if they are shadowed already covers the previous case, let's just mimic it.
