‘Node’ images are just minimal CentOS plus all the packages for this release, in a sub-DVD sized ISO.  Once it is installed, the operating system is still CentOS, and can be patched/modified, including installing alternative kernels.

If it fails, boot back to the original kernel, and remove the package from Elrepo, or at worse, re-install.

Thanks Matthew,

Are you sure about this?

I thought oVirt Node NG images are immutable

Hi oVirt Users,

I am trying to test some vfio related stuff on oVirt Node NG 4.4.4 based host.

What would be the easiest way to have a 5.x kernel on this node?

I don't mind compiling if it needs to.

Cheers,

Shantur
