XEN doesn't boot on Minnowboard #59

Closed gogo9th closed 7 years ago

gogo9th commented 7 years ago

Hi,

I installed XEN 4.8 on Minnowboard (sudo apt install xen-hypervisor-amd64), but DOM0 kernel images based on XEN hypervisor don't boot up at all. Does anyone have the same issue? Is Minnowboard incopatible with Minnowboard? Please share with me any clue... Thanks!

When I boot Linux 4.4.0-92-generic XEN 4.6-amd64 hypervisor, I get the warning:

WARNING: no console will be available to OS Loading Linux 4.4.0-92-generic ... Loading initial ramdisk ...

Then, after 10 seconds, the whole texts above get shifted to some random location on the screen and I get two horizontal rainbow lines on the screen.

Here are more updates. Apparently, XEN 4.9 started servicing EFI boot with GRUB2: https://wiki.xenproject.org/wiki/Xen_Project_4.9_Feature_List

But if I install xen with apt install, its version is 4.8. So I downloaded XEN source code from here: https://xenproject.org/downloads/xen-archives/xen-project-49-series/xen-project-490.html

and installed XEN following this tutorial: https://mhsamsal.wordpress.com/2013/12/05/configuring-virtual-tpm-vtpm-for-xen-4-3-guest-virtual-machines/

However, when I run XEN 4.9, I still get exactly the same message as before:

Loading Xen 4.9.0 ... WARNING: no console will be available to OS Loading Linux 4.4.0-92-generic ... Loading initial ramdisk ...

Could anybody please try running XEN 4.9 on Minnowboard? Please help me out...!

I've never tried myself but when googling for possible hints I saw someone who mentionned he was struggling with the initramfs and ended up removing that from the OS he was trying to boot.

Thanks and I finally found the solution.
