no boot on xen vserver after fresh install

Hi,

I have a vserver (Strato, Servercloud, xen based), installed os is Debian 7 64bit.

From a recovery-system I shrinked the existing partition, created a 2nd one, then following https://wiki.archlinux.org/index.php/In … ting_Linux to install Arch in the 2nd partition.

From the already installed Debian I used os-prober to include the new arch into Debian's grub2:

$ update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.2.0-4-amd64
Found initrd image: /boot/initrd.img-3.2.0-4-amd64
Found Arch Linux (rolling) on /dev/xvda2
done

With GRUB_DEFAULT=2 the system won't boot any more.

I have access to a recovery-system. A serial console won't work during grub, only after the kernel is loaded :-(

How could I debug the problem? Are there any logfiles?

Thanks :-)
