...6, but this was covered previously (at least for 7...not sure how much they differ)...not that I can find the message now, but here's what I recall/pieced together from bash history that works on CentOS 7: If the microcode you want is in the microcode_ctl package: mkdir -p /etc/microcode_ctl/ucode_with_caveats/ touch /etc/microcode_ctl/ucode_with_caveats/force yum reinstall microcode_ctl (there were arguably better ways to do this part, but I cant recall) add ucode=scan to your GRUB_CMDLINE_XEN_DEFAULT line grub2-mkconfig to update your grub config reboot Once that's done, every time microcode...

...tall the microcode into the initramfs if the kernel isn't "known good" because of various issues with Linux kernel patches being needed for certain microcode features. There is a quick way to get it to force the microcode into the initramfs of any kernel: mkdir -p /etc/microcode_ctl/ucode_with_caveats/ touch /etc/microcode_ctl/ucode_with_caveats/force This only works with the most recent version of microcode_ctl (2.1-29.16.el7_5.x86_64). If you do this, you can then run 'yum reinstall microcode_ctl' and you should get the microcode in the initramfs after it finishes. Note that this w...
