Bonjour, Bertrand,
Thank you for your reply. I am a newbie to Xen but I’ve used Bhyve, Vmware and MSFT Hyper-V before so I am somewhat familiar with how type-1 hypervisors work. Still.
🤔
I've enclosed:
- The script I used to try to set up Dom0. It’s basically the script I found here:
https://angryelectron.com/how-to-install-ubuntu-as-xen-dom0-and-domu/, except, slightly modified for AArch64/ARMv8 as close as I was able to determine it.
- The grub.cfg file.
As I said, the serial port STDOUT goes dead so no logs. Please help me understand how to turn on logging so I can figure out what’s going on.
The machine I’m porting to is this one:
https://www.gigabyte.com/tw/ARM-Server/R281-T94-rev-100#ov
It has 128G RAM and a total of 5TB of SAS and SSD disk. I’m booting off one of the SSDs.
It runs Ubuntu 20.04 LTS just fine; I even have a UEFI GOP driver for the AMD Radeon R9 GPU I plugged in. All of that works fine with Ubuntu.
Thanks in advance for any ideas
Rgds.,
~Sam

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.

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 ?
