As far as I know, RHEL6/7/8 kernels do not run as dom0. You should check the CentOS-virt project[0], which maintains xen, kernel and a whole libvirt xen stack, though not yet available for EL8.

I did get a cut down xen to build on RHEL8 (for example discount is only needed for documentation) purely as a test, but of course it was never going to be useful or testable because RHEL8 kernels are built without the necessary configuration options to use xen as a Dom0 (eg. no CONFIG_XEN_DOM0 set). Thus I agree that you are best looking at the CentOS-virt project.

Thanks for the responses.  SIG-Virt it is..

Hello,

I've built xen-4.12.1 with help from patches by Mike Young. I also had to include builds qemu-3.0.1 and qemu-xen-traditional in separate packages since there is no qemu-system-x86 package anymore.

For dom0 kernel, use elrepo kernel-ml for el8, version 5.3.4* or higher. This build is running very stable and using low resources.
