I'm drafting a bug report for xen-devel. To do this, I'm trying to
reproduce my issue ("IO-APIC + timer doesn't work") on Ubuntu 19.10.
Unfortunately, I can't figure out how to enable verbose logging on Ubuntu
w/ Xen.
Here's what's displayed on the screen when I boot (followed by a reboot).
Loading Xen 4.9-amd64 ...
Loading Linux 5.4.0-24-generic ...
Loading initial ramdisk ...
_
Following the Debugging Xen wiki page [1], I've changed my xen.gz grub
line to the following, but it doesn't seem to do anything.
multiboot2 /boot/xen-4.9-amd64.gz placeholder loglvl=all guest_loglvl=all ${xen_rm_opts}
I've tried removing `quiet splash` from the vmlinuz grub line, with no
success. I've also unsuccessfully tried adding `loglvl=all` to the
vmlinuz and initrd lines.
This is on a Dell XPS 13 laptop, so I don't think accessing a seriel
console would be easy.
On the Xen wiki [2], I noticed that this might be a UEFI issue:
> Go into your BIOS and enable Legacy Booting (non-EFI). If it still
> doesn't work, upgrade the BIOS to its latest version.
My BIOS is up-to-date and has no option to disable UEFI. Yet, somehow
Ubuntu w/ Xen is still booting via grub.
Where should I go from here?
Thanks,
Aaron Janse
