pygrub regression with latest xen-unstable test

pygrub regression with latest xen-unstable test

[Fabio Fantoni]

After updating to latest xen-unstable (commit 
7d203b337fb2dcd148d2df850e25b67c792d4d0b) I'm unable to boot an old domU 
with grub 1 cfg.
I not remember the previous unstable build tested that successfull boot 
it, probably is of 1-2 months ago or more.

According to the git log pygrub hasn't changed since late Jun, and in
general changes very little. Could you look back over the history and
see if you can identify the problem commit?

Thanks,
Ian.

I take fast look on latest pygrub changes, I changed the xvda1 of disk 
to xvda, tried also root in cfg but nothing.
After I tried to put grub2 cfg in menu.lst and gave "Unknown directive" 
warnings at boot, so read it.
After I renamed menu.lst to grub.cfg and nagios booted correctly.
So the regression seems in parsing of grub1 cfg in menu.lst file but I 
not found how to solve it.

Is the contents of this file grub1 or grub2 syntax?

Did you look back into the git history as I suggested?

The regression is in grub1 syntax in menu.lst file, with grub2 syntax in 
grub.cfg is ok.

Yes I did a fast look and did a fast tests to try to search the problem, 
I found only the details reported above.

Please can you attach the actual problematic config file.

While searching my mbox for this thread I stumbled over:
http://lists.xen.org/archives/html/xen-devel/2014-09/msg01053.html which
might be related?

Already posted in first msg:
#boot/grub/menu.lst
title Lenny 2.6.26
root (hd0,0)
kernel /boot/vmlinuz-2.6.26-2-xen-amd64 ro root=/dev/xvda1 console=hvc0 
xencons=tty
initrd /boot/initrd.img-2.6.26-2-xen-amd64

Or you mean other config file?

I'll try it on my next test build.

Was that the entire file? I thought it was just a snippet (it's not the
autogenerated one from Debian, I don't think).

On old domUs installing grub1 was always failed, so I created menu.lst 
manually each domUs and always was working until xen-unstable of latest 
months.
Grub2 on recent domUs instead install correctly and generate cfg 
automatically.
Major of pv domUs are debian, some ubuntu and rare are others (ipfire, 
clearos, fedora ecc...)
