Can you show us your xen domu config file? I'm interested in what method you are using to boot these. If you're using pvgrub2 to boot PV mode then the bad news is that it seems to be largely abandoned as nobody wants to alter it to support different kernel compression methods. The good news is that you should be able to easily switch to PVH mode with pvhgrub which uses grub's core routines to decompress the kernel and therefore supports whatever compression methods that grub normally does.
