I am running XEN on CentOS Linux release 7.8.2003

I have a Debian 7, and two Gentoo DomU Guests running fine.

I am trying to get an Ubuntu 20.04 DomU Guest running but I get this error when trying to run the netboot kernel image

xc_dom_probe_bzimage_kernel unable to LZ4 decompress kernel

I understand that CentOS Xen does not support LZ4 decompression.

Is there a workaround for this?

Use HVM and a bootloader.
