That pretty much explains what happened: you don't have any
/boot/grub2/grub.cfg and when looking for
/boot/grub/grub.cfg GRUB
found
its own memdisk and fell into recursion. I'm not sure what
should
be the
proper way to solve this recursion.
Yes, it was a bit naive on my side. Recursion in principle can be
stopped by using global variable, but search is limited to the
first
match only anyway, so I guess it is not worth it.
Anyone know how to exclude memdisk from the search please?
Please look in grub2 sources at docs/osdetect.cfg. It implements
advanced run-time detection of possible bootable files from
various operating systems. It boils down to loop across all
devices,
and of course you can either limit device names (like looking
for hd*
only) or explicitly exclude known ones (like memdisk).
Is it possible to specify a different default grub.cfg path
(different
from all other distributions) changing this command:
./grub-mkstandalone --grub-mkimage=./grub-mkimage -o
pvgrub2.xen -O
x86_64-xen -d grub-core/ boot/grub/grub.cfg
Is it hardcoded as /boot/grub/grub.cfg for grub memdisk or can be
set?
Not really. Currently the situation is
- grub-mkstandalone hardcodes $prefix as (memdisk)/boot/grub
- after launch grub unconditionally starts "normal" module if at
all
possible
- normal module always tries to load and execute $prefix/grub.cfg
if no
explicit configuration file name is given as argument
But I think that using osdetect.cfg or something based on this idea
won't require changing defaults at all.
Thanks for your reply.
I did this script that is working about finding and include the
grub.cfg
of pv domUs with many cases:
cat > boot/grub/grub.cfg <<EOF
insmod lvm
insmod ext2
insmod part_msdos
insmod part_gpt
insmod btrfs
insmod regexp
for dev in (*); do
# $device: parenthesis removed from $dev
regexp -s device '\((.*)\)' $dev
set root=$device
for file in /boot/vmlinuz-* /boot/linux-*; do
if test -f $file; then
set saved_root=$root
fi
done
done
set root=$saved_root
if test -f /boot/grub2/grub.cfg ; then
configfile /boot/grub2/grub.cfg
elif test -f /boot/grub/grub.cfg ; then
configfile /boot/grub/grub.cfg
fi
EOF
@xen developer: Are there other modules to insert for other
partitions
or file systems, other grub cfg path for other distributions or
other
kernel type to search that support xen pv domUs?
I think is good do and post complete pvgrub2 cfg that support all pv
domUs.
@xen and grub developer: I'm still unable to boot any entry of
Sid pv
domU using official kernel:
xl -vvv create -c /etc/xen/sid.cfg
...
Caricamento Linux 3.11-1-amd64...

Any ideas?
Ah I forgot: you need to "insmod xzio" since debian ones are
compressed.
If you need more tests/informations tell me and I'll post them.
Thanks for any reply.
Thanks for reply, in the meantime I rebuilt updated grub2 from git
(commit b67422d33de8eee83700db534a45b2ac5e5ed67a) and there is a
regression from build of some days ago (I don't remember the exact
commit, probably was of 24 or 25 november).
Fails on script I posted on previous mail showing some errors:
kern/dl.c:619: module name: test
kern/dl.c:620: init function: 0x3f5abdd4
error: two arguments expected.

Full log with debug on attachment.
I updated git to commit 69ca97c820a623f85baf2db1627e19bef9c24e44 and
the
regression persist.
About Sid boot adding "insmod xzio" not solve the problem.
Can you give me details of your working cases?
Can you send me the exact kernel? My sid kernel work fine.
(Resent re-adding xen-devel and grub-devel)
I have updated Sid domU today before retry with pvgrub2.
Latest version of kernel and grub is installed, on attachment the
grub.cfg of domU.
If domU's grub.cfg is ok, what is git commit and details of your pvgrub2
build working?
My actual build is:
git clone git://git.sv.gnu.org/grub.git
./autogen.sh
./configure --target=x86_64 --with-platform=xen
make
mkdir -p boot/grub/
cat > boot/grub/grub.cfg <<EOF

./grub-mkstandalone --grub-mkimage=./grub-mkimage -o pvgrub2.xen -O

And I use Wheezy (debian 7) as dom0 with xen-unstable from git.
If you need more tests/informations tell me and I'll post them.
