My guess is that the issue is one of these two:
1) version mismatch between Xen and Xen tools
E.g. Xen from staging and Xen Tools from 4.18
2) missing Xen modules in Linux Dom0
Was /etc/init.d/xencommons run at boot?
Is /proc/xen mounted?
Are the privcmd, gntdev, xenfs, modules
I've found a similar error on this post,made on 2012 :
https://groups.google.com/g/qubes-devel/c/W1lM4ELuVVI
and according to what has been asked there,I want to post some further
relevant informations to help you to help me to debug
the problem :
root@devuan-bunsen:/Dati/xen# xl dmesg --->
Hello to everyone.
I'm trying to boot Linux 6.1.y as Xen dom0 on the Chromebook xe303c12, aka
Snow and configure and start a very basic domU guest,following the Chuck's
tutorial,located here :
https://github.com/mobile-virt/u-boot-chromebook-xe303c12/tree/chromebook/xen#starting-a-domu-guest
---> So I plan to do some tests and see what DMA ops the other devices use
if swiotlb-xen is disabled and also what DMA ops the other devices use when
Linux runs on the Chromebook on bare metal without Xen. If these tests show
the problem can be fixed by disabling swiotlb-xen with a Kconfig or
