I've tried to add openSUSE 10.2 x64 a4 on a quite out of the box new
Dell Precision 490 workstation (Xeon 5160, NVidia FX550 Quadro, USB
mouse, 250 GB Samsung SATA disk, 2 GB RAM) which was preloaded with
WinXP on a single 233 GB NTFS partition.

Beside the known mouse/keyboard cursor problems (recent comments #22 and
#23 to bug id 203609), I encountered a 10.2 faulty and somewhat strange
diskpartitioning. In the lack of a suggested diskpartitiong for a Xen
server(does it exist?), I thought to try a traditional dual/multiboot
partitioning first.

The first, default partitioning during the installation, suggested to
shrink the WinXP/NTFS /dev/sda2 to 14 GB, and slice the extended 218 GB
(sda3) into 2 GB swap (sda5), 20 GB for / (sda6) and the rest 196 GB for
/home (sda7). Accepting this, the partitioning ran into an error code
(sorry I didn't write it down) dealing with sda2, and before formatting
the other partitions, and I had to stop the installation.

Booted WinXP which ran file check, and I verified the C: disk was
resized to 14 GB (with 7 GB free). But at the same time the rest of the
disk was still denoted NTFS. I ran also defragmenting on the C: disk
(for safe).

Tried next a second new openSUSE 10.2 installation. This time I became
surprised that the WinXP sda5 was suggested even more shrinked, down to
9 GB only and else partioning similar as above.
Why this second shrink of sda5, when it obviously wasn't necessary and
neither easy to change (keep) back?

But also this time the 10.2 partitioning failed dealing with sda5, and I
had to break the installation.

Did then try the openSUSE 10.1 installation DVD instead and the
suggested partitioning became indentical as the latter. However, this
partitioning and formatting did run through correctly. Afterwards I
stopped this 10.1 installation to install 10.2 again this time on the
pre-partioned disk. And now this worked (based partitioning on the
suggested shceme and customized it).

I would expect this is a bug in the 10.2 x64 a4 partitioning, as it
works with 10.1.

I also wonder why the swap partition was sized to 2 GB only, while it
normally is suggested as 2xRAM (2 GB)? I could neither find an easy way
to extend the suggested swap partition, based on the default suggestion.

And lastly, how to really partition the disk for running Xen server with
WinXP and SUSE 10.2 (utilizing Intel-VT)?
