From aede5d5dfc5f3e4ea7467b28c51fda2f8945d117 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Fri, 1 Feb 2019 13:29:08 +0100 Subject: [PATCH] s390x/pci: mark zpci devices as unmigratable We currently don't migrate any state for zpci devices, which are coupled with standard pci devices. This means funny things happen when we e.g. try to migrate with a virtio-pci device but the s390x- specific zpci state is not migrated (vfio-pci is not affected, as it is not migratable anyway.) Until this is fixed, mark zpci devices as unmigratable.
