BTW, install your dom0 root partition within a 5G lvm logical volume, leaving free blocks for you domUs within your big VG.
For example LVM on top of RAID1 (two mirrored discs of 500G) for Xen:
Disc SDA:
/dev/sda1 type MD with 256M
/dev/sda2 type MD with 500G
Disc SDB:
/dev/sdb1 type MD with 256M
/dev/sdb2 type MD with 500G
Raid Volumes:
/dev/md0 with sda1 and sdb2 type bootable raid1 on /boot
/dev/md1 with sda2 and sdb2 type LVM
LVM Volumes:
/dev/md1 as a physical lvm volume
vgcreate HyperVG01 /dev/md1
lvcreate -L 1G -n xenhost01-swap HyperVG01
lvcreate -L 5G -n xenhost01-root HyperVG01
Of course, you probably will make this raid and LVM volumes during the Debian installation...
Doing this, you will have 495G of free space within HyperVG01 VG volume for you domUs and a simple partition scheme at your discs.
You /boot partition will me mirrored too! So you can install GRUB in your /dev/sdb and make the system bootable when sda fail.
I hope this big picture can help you!

Hi!
I have a tip for you:
1- Get the ISO of the Debian Lenny 5.0 amd64 from http://debian.org;
2- Install your Debian into your own partition scheme (LVM over RAID);
3- Reboot into your new fresh Debian Lenny; upgrade it;
4- * GRUB1 is still the default in Lenny, verify it;
5- Install the Xen with the command: "aptitude install xen-linux-system-2.6.26-2-xen-amd64";
6- Reboot into you new dom0.
Cheers!

Hi. I have series x3500 ibm server running xen 3.0.3 from etch. When trying to
use xen 3.2.1 from lenny, xen hangs without any messages just after grub2
starts booting the xen image.
When I tried livexen cd with xen 3.2.1 from lenny, it works just fine. The
only difference is probably that livexen uses grub legacy, while I have to use
grub2, because my root is on raid+lvm.
Also, current configuration doesn't see all of the 6GB of ram, only the first
3GB, even with pae xen installed, that's why I'm trying to get newer xen up.
However It might be problem with grub but I have no idea how to find out.
I'd like to try to find out if I really can't get newer xen running before
I'll have to try using kvm or something like that.
Could anyone point me in some useful direction?
thanks
Martin Kraus
