 ==== VirtualBox running CentOS 8 Notes ==== ==== VirtualBox running CentOS 8 Notes ====
  
-__4 October 2019__+__9 December 2020__ 
 +  * Updated to CentOS Linux release 8.3.2011 
 +  * Booting into new kernel kept failing 
 +    * complained /boot ext4 filesystem was unknown 
 +  * Booted into previous kernel OK 
 +  * Did "rpm -qa |grep kernel | sort" and looked for all the latest versions
  
-  * First attempt for netinstall +  kernel-4.18.0-240.1.1.el8_3.x86_64 
-    * Used CentOS-Stream-x86_64-boot.iso +  kernel-core-4.18.0-240.1.1.el8_3.x86_64 
-  * Review [[https://bugs.centos.org/view.php?id=16456|notes on net installation URL problems]] to use proper network URL for package downloads +  kernel-devel-4.18.0-240.1.1.el8_3.x86_64 
-  * First go here: http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=BaseOS +  kernel-headers-4.18.0-240.1.1.el8_3.x86_64 
-    * Choose one from list +  kernel-modules-4.18.0-240.1.1.el8_3.x86_64 
-      This worked: http://www.gtlib.gatech.edu/pub/centos/8.0.1905/BaseOS/x86_64/os+  kernel-modules-extra-4.18.0-240.1.1.el8_3.x86_64 
 +  kernel-tools-4.18.0-240.1.1.el8_3.x86_64 
 +  kernel-tools-libs-4.18.0-240.1.1.el8_3.x86_64 
 +   
 +Then reinstalled all of them using: 
 + 
 +  dnf reinstall kernel-4.18.0-240.1.1.el8_3.x86_64 kernel-core-4.18.0-240.1.1.el8_3.x86_64 kernel-devel-4.18.0-240.1.1.el8_3.x86_64 kernel-headers-4.18.0-240.1.1.el8_3.x86_64 kernel-modules-4.18.0-240.1.1.el8_3.x86_64 kernel-modules-extra-4.18.0-240.1.1.el8_3.x86_64 kernel-tools-4.18.0-240.1.1.el8_3.x86_64 kernel-tools-libs-4.18.0-240.1.1.el8_3.x86_64
