Re: Booting the FreeBSD kernel as an zImage file needs a patch upgrade ?.

[Mario Marietto <marietto2008@xxxxxxxxx>]

Hello.

I've recompiled the kernel (vers. 5.4.261) enabling ALL the parameters related to xen,looking for the word "xen" and I've set Y to every parameter to facilitate things. Unfortunately I've got the same error. I've added my kernel config file if you want to give a look. Thanks.

This line means libxl is still waiting for the backend to detect the
device configuration. This would confirm that the backend driver is
probably not loaded.

You can check in the Linux configuration is CONFIG_XEN_BLKDEV_BACKEND is
set. If it is:
   * N, then please consider to rebuild it
   * M, then this is a module. You would want to use 'modprobe' to load
it. That's assuming the module is present on your system.
   * Y, then this should have been loaded. You should check the kernel
logs to see any errors.
