If the backend crashes and restarts, the device is broken. This patch adds reconnect for vhost-user-scsi. This patch also improves the error messages, and reports some silent errors. Tested with spdk backend. Signed-off-by: Li Feng <fengli@smartx.com> Message-Id: <20231009044735.941655-4-fengli@smartx.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.
