QEMU has currently two ways to prevent migration to occur: - migration blocker when it depends on runtime state - VMStateDescription.unmigratable when migration is not supported at all This patch gathers all the logic into a single function to be called from both the savevm and the migrate paths. This fixes a bug with 9p, at least, where savevm would succeed and the following would happen in the guest after loadvm: $ ls /host ls: cannot access /host: Protocol error With this patch: (qemu) savevm foo Migration is disabled when VirtFS export path '/' is mounted in the guest using mount_tag 'host' Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <146239057139.11271.9011797645454781543.stgit@bahia.huguette.org> [Update subject according to Paolo's suggestion - Amit] Signed-off-by: Amit Shah <amit.shah@redhat.com> |
