I was hoping to get more diagnostics out to get it working under QEMU
TCG so I think must of missed a step:
Loading Xen 4.15-unstable ...
Loading Linux 4.19.0-11-arm64 ...
Loading initial ramdisk ...
Using modules provided by bootloader in FDT
Xen 4.15-unstable (c/s Sat Sep 26 21:55:42 2020 +0100 git:72f3d495d0) EFI loader
...silence...
I have a grub installed from testing on a buster base:
dpkg --status grub-arm64-efi
Version: 2.04-8
With:
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="console=ttyAMA0"
GRUB_CMDLINE_LINUX_XEN_REPLACE="console=hvc0 earlyprintk=xen"
GRUB_CMDLINE_XEN="loglvl=all guest_loglvl=all com1=115200,8n1,0x3e8,5console=com1,vg"
And I built Xen with --enable-systemd and tweaked the hypervisor .config:
CONFIG_EXPERT=y
CONFIG_ACPI=y
So any pointers to make it more verbose would be helpful.
