Dear *,

This is still related to one of my previous posts ... just digesting it into small pieces. In the past I was able to get rid of the partition table of a domU (either image file or LVM based) by :

1 - mounting the domU (mount -o loop, kpartx and alike)
2 - copying the contents into a fresh LV
3 - edit the xen configuration files, as well as fstab and grub.conf if needed
4 - boot the new LV domU with pygrub and ... that's it.

I found that not having the partition table was easy to handle, whenever I want to make a backup (either dd or tar) and restore it (and that's what I read many times also). I only need to take care of the consistency of the filesystem of the LVM, not worrying myself with the consistency of the partition table.

But now I'm not being able to do it in a fresh CentOS54 x86_64 xen aware dom0, while using the old 4.8 version (those times still using x86 for both domU and dom0) I was not experiencing any problems.

Someone with experience in this matter?
Tot ziens,

Possible something has changed in the default xen installed in the 4.x and 5.x CentOS e
