Hi Samuel,

So, I’m trying to get a Xen Dom0 and DomU, both running Ubuntu 20.04 LTS up on our brand-new Gigabyte ThunderX2 ARM64 box. I can get Ubuntu up and running, but after installing the Xen bits, it dies after the UEFI layer launches GRUB. I haven’t been able to get any logfiles because it doesn’t get that far. Nothing shows up on the serial port log either – it just hangs.

Has anyone over there been trying to get a similar setup running? Am I out to lunch for trying this, or is there something I’m missing? Any help at all would be appreciated.

I am currently porting Xen on an N1SDP arm board which is also using a EDK2/grub setup and I manage to start xen from grub and then start dom0 providing a DTB.

My grub configuration looks like this:
menuentry 'xen' {
   xen_hypervisor $prefix/xen.efi loglvl=all guest_loglvl=all console=dtuart dtuart=serial0 dom0_mem=1G
   xen_module $prefix/Image console=hvc0 efi=noruntime rw root=/dev/sda1 rootwait
   devicetree $prefix/n1sdp.dtb

Could you share your grub configuration ?


If this doesn’t work, I’m going to have to go to FreeBSD and Bhyve because I know someone who has that working. I’d rather use Linux than BSD for this application, there are more drivers supporting this hardaware.
