RHEL 8.4 上 vmmon 错误导致无法启动VMware® Workstation

published: updated: Linux 技巧(原创)

1 环境

  • 如果在尝试 VMware Workstation 15 的 evaluation 版本
  • xorg-x11-drv-vmware-13.2.1-8.el8.x86_64
  • Red Hat Enterprise Linux release 8.4 (Ootpa)
  • 4.18.0-305.el8.x86_64

2 启动的时候，出现错误。可以看到 machine monitor 出错了

3 通过这个错误. 可以知道，肯定是 vmmon 无法正常加载了。

3.1 检查RHEL 8.4 的源码 （开源就是好呀，随时可以看源码 ：D）

  • 通过源码可以知道，RHEL8.4 有一个 commint （过程不说了，就看重点）

    mm: memcg: convert vmstat slab counters to bytes
    In order to prepare for per-object slab memory accounting, convert
    NR_SLAB_RECLAIMABLE and NR_SLAB_UNRECLAIMABLE vmstat items to bytes.
    To make it obvious, rename them to NR_SLAB_RECLAIMABLE_B and
    NR_SLAB_UNRECLAIMABLE_B (similar to NR_KERNEL_STACK_KB).

    3.2 检查 vmmon 的源码 hostif.c， 可以看到里面用的还是旧名字； ok 问题找到，那就好办了，直接修改。这个应该是vmware 的bug了，没有及时修正来适配新的内核。

    3.3 修改完毕,重新编译这个模块就好了

    3.4 编译完毕，重新加载后，就可以正常使用了。
