I am new to CentOS (Debian user) and I am looking for way how to install CentOS 5 on domU in the way that I have it directly on dom0 LVM partition. If I install it with virtual-manager then the installation program takes that partition as a disk and then creates new partitions on it. I don't want it that way because I cannot then mount it from dom0.

Is there some way how to install it directly on partition as for example in Debian with debootstrap?
Only by manually building a tarball of a working OS image, and laying it onto your partitions directly. Take a look at www.jailtime.org for samples. Note that pygrub, and grub itself, *will not work* if you do this. Grub needs to see a disk, not just partitions, for various configuration reasons. This may be soluble in the long term, but I lacked time to play iwth it.

Why not use partitions on partitions, and use "kpartx" to make them accessible from the Dom0?
