Fedora rawhide is about to to update to Python 3.8 (in beta I think) and
there are two issues with compiling xen with it (see
https://bugzilla.redhat.com/show_bug.cgi?id=1704807 ).
It seems that in 3.8 python3-config --libs no longer includes -lpython3.8
by default which causes tools/configure
I have been looking at the pygrub code to see if it is possible to cope
with grub files with BLSCFG and spotted this minor issue in GrubConf.py
where the code intends to replace ${saved_entry} and ${next_entry} with 0
but doesn't succeed.

This patch may help your issue with the default kernel setting on Fedora
30 as it uses the setting of saved_entry or next_entry from the grubenv
file to choose the default kernel which should override any setting picked
up from if clauses in the grub.cfg file.
I have only done limited and somew

I have been testing the python3 changes committed to xen and found a few
issues. There are a couple of ocaml python build scripts that don't work
for me with python3, and I needed a few fixes to get pygrub to work,
mostly due to the change from strings to bytes. I am attaching the patch I
put t

This series of patches is to improve the parsing by pygrub of grub
configuration on Fedora. The current result of parsing is generally
that the second kernel listed is set as the default due to a
set default=1 line in grub.cfg which is only intended to be
reached after repeated boot failures.

When a grub.cfg file is found this patch checks if there is grubenv
file in the same directory as the grub.cfg file. If there is it
passes the contents to parse().

This patch reads the contents of a grubenv file if available, and
uses the value of next_entry (in preference) or of saved_entry to
set the default kernel if there is a matching title or if it is a
number. If either next_entry or saved_entry is set and neither is
used then the default is set to 0.
