I have not used xen in a long time so cannot help there. From my experience with grub, sometimes you have to manually configure what the possible boot devices are. But, have you considered Linux's own VM tech, using KVM and QEMU ? It has a nice option of loading the kernel before starting the VM, thus bypassing the need for grub entirely. virt-manager is an OK GUI to get going with it. There are also various web based tools to manage the VMs also. I have been playing with an AMD Vega GPU passthru on it recently, and fixed a QEMU bug on the way. AMD developers are very easy to get hold of when needed. Works very nicely, and stably now.
