Unable to change the kernel in fedora-25 template

[pietrushnic]

Qubes OS version:

R4.0

Affected TemplateVMs:

fedora-25

---

Steps to reproduce the behavior:

I'm trying to follow this documentation section Installing kernel in Fedora VM.

I was able to install 4.13.5-100 kernel. Unfortunately I'm not able to boot it using properties.

Expected behavior:

I should be able to change VM kernel.

Actual behavior:

Trying pvgrub2 gives ability to set but do not detect file:

[pietrushnic@dom0 src]$ qvm-start fedora-25
Missing file: /var/lib/qubes/vm-kernels/pvgrub2/modules.img

Trying existing build kernel 4.13.5-100:

[pietrushnic@dom0 src]$ qvm-prefs -s fedora-25 kernel 4.13.5-100
Traceback (most recent call last):
  File "/usr/bin/qvm-prefs", line 9, in <module>
    load_entry_point('qubesadmin==4.0.7', 'console_scripts', 'qvm-prefs')()

    str(value).encode('utf-8'))
  File "/usr/lib/python3.5/site-packages/qubesadmin/base.py", line 69, in qubesd_call
    payload_stream)
  File "/usr/lib/python3.5/site-packages/qubesadmin/app.py", line 481, in qubesd_call
    return self._parse_qubesd_response(return_data)
  File "/usr/lib/python3.5/site-packages/qubesadmin/base.py", line 103, in _parse_qubesd_response
    raise exc_class(format_string, *args)
qubesadmin.exc.QubesPropertyValueError: Kernel '4.13.5-100' not installed

Same thing when I try full directory name 4.13.5-100.fc25.x86_64

I realized that missing file may mean content of dom0, but after copying all files from fedora-25 to dom0 I still was not able to boot:

[pietrushnic@dom0 src]$ qvm-start fedora-25
Start failed: internal error: libxenlight failed to create new domain 'fedora-25'

What is correct way of buidling and reaplcing kernel ?

General notes:

This is result of my continue fight to fix Intel 8260 which hangs after S3. What I would like to try are different ucode files.

Set kernel to empty value ("(none)" if doing via GUI).
This is a duplicate of #3136
