This could mean that the problem is actually in grub? > Dom0 package versions on the test machine: > > ii grub-xen-host 2.02+dfsg1-9 > ii linux-image-4.18.0-3-amd64 4.18.20-2 > ii xen-hypervisor-4.11-amd64 4.11.1~pre.20180911.5acdd26fdc+dfsg-5 Have you upgraded your Dom0 to Stable? That has grub 2.04-20, kernel 5.10 and Xen version 4.14.x and that may just fix the issue. I haven't used the cloud kernel myself, but I do have a machine running Xen and the compression used for cloud kernels is (AFAIK) the same as for 'normal' kernels and I never have problems booting domU's (apart from when I mess things up myself ;-P).
