From 08f7c2582c224c9d8d824fa8dff41594ef18af66 Mon Sep 17 00:00:00 2001 From: Kunhui-Li Date: Mon, 21 Feb 2022 15:13:50 +0800 Subject: [PATCH] config_tools: remove some obsolete code Since PRs #7115 and #6664 have landed, the ivshmem and hv_ram_size have been refined, some related checks are obsolete in config tool. So we remove these checks here.
