I'm trying to figure out how to replace the vmlinuz and initrd.img from CentOS 7.4 with "fixed" kernel-plus versions in order create CentOS 7.4 VM's. So far I'm stuck booting via 7.3 install, adding new kernel-plus and upgrading to 7.4. I've not found any complete Google answers and was looking for help making sure I choose the correct approach.
I've tried to build an initrd.img from a kernel-plus booting system via "mkinitrd -f -v /boot/initrd.img $(uname -r)", but the file size is less than half the one from CentOS 7.4 (17MB -vs- 47MB). I'm not even sure I can just replace those files yet either.
Any help going the correct path?
I have not had time to do this yet .. BUT .. you can edit the lorax template to to use kernel-plus instead of kernel (and new repodata).. then rerun lorax to get a bootable tree and boot.iso
You would then need a tree with the new kernel-plus* packages instead of the kernel-* packages
This bug kind of explains the process:
https://bugs.centos.org/view.php?id=13763
(look for lorax in the bug)
I do want to create a process and tree somewhere for this (likely on buildlogs.centos.org). Sometime soon after I finish the i386 distro release (hopefully that is this week .. next week for some kind of bootable x86_64 Xen PV solution).
The good news is, the 7.5 RHEL kernel Source RPMs should have Kevin's patch in it and it should work as released on Xen PV.
