Xen project Mailing List

Sorry for the duplicate post if you belong to xen-devel, I realized I had sent this to xen-devel yesturday and that was probably the wrong list to use.. Now to the problem at hand!

We are experiencing a odd issue after we built grub2 support. The image we built works fine on some hosts and then just hangs on others.

I built grub2 as follows...

-------------

git clone http://git.savannah.gnu.org/cgit/grub.git

cd grub

wget http://prgmr.com/~srn/grub2/xen-linux16.patch

patch -p1 < xen-linux16.patch

./autogen.sh

./configure --target=x86_64 --with-platform=xen --prefix=/opt/grub2

make

make install

export PATH=/opt/grub2/bin:/opt/grub2/sbin:$PATH

Next I built the image as follows...

---------------

cat > grub-bootstrap.cfg << EOF
normal (memdisk)/grub.cfg
EOF

cat > grub.cfg << EOF
for grubcfg in /boot/grub2/grub.cfg /boot/grub2/grub2.cfg /boot/grub/grub2.cfg /boot/grub/grub.cfg /grub2/grub2.cfg /grub/grub.cfg /etc/grub2.cfg /etc/grub.cfg ; do
   if search -s -f $grubcfg ; then
      echo "Reading (${root}$grubcfg"
      configfile $grubcfg
   fi
done
EOF

tar cf memdisk.tar grub.cfg
/opt/grub2/bin/grub-mkimage -O x86_64-xen -c grub-bootstrap.cfg -m memdisk.tar -o grub2-x86_64 /opt/grub2/lib/grub/x86_64-xen/*.mod

This works fine on some of our hosts, but then just seams to hang on others. When starting the guest i see the following...

[root@devhostxxx ~]# xm create -c /home/username/vs.config
Using config file "/home/username/vs.config".
Started domain username (id=34)
[root@devhostxxx ~]#

Then it just hangs from their.

These hosts are CentOS 6 using the CentOS-Xen RPMS. Hosts are running Xen version 4.4.1-8el6 and still using xend with xm commands

Any idea what may be going on here? Or how i should go about debugging this issue?

[Xen-users] GRUB2 randomly works on some hosts but not others?
