Bug 622505

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.3) Gecko/20060425 SUSE/1.5.0.3-7 Firefox/1.5.0.3

Trying to upgrade a XEM-dum-U system by means of booting from (an image of) a bootable 11.3 cdrom

I made a xen-config file like:
disk =[ 'file:/srv/distro//iso/suse/open/11.3/openSUSE-NET-Build0694-x86_64.iso,sde:cdrom,r', 'phy:/dev/xen-productie/kc3001-boot,sda,w','phy:/dev/xen-productie/kc3001-swap,sdb,w',  'phy:/dev/xen-productie/kc3001-syst,sdc,w', 'phy:/dev/xen-productie/kc3001-data,sdd,w' ] 
memory = 1024 
vcpus = 2 
builder = 'linux'
name = 'kc3001'
dhcp = 'dhcp'
kernel = '/srv/xen/install/openSUSE_11.3/vmlinuz64'
ramdisk = '/srv/xen/install/openSUSE_11.3/initrd64'
vif = [  'mac=00:16:3E:30:72:00' ]
localtime = 0
on_poweroff = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
nographic = 1
extra = 'install=http://kc-suse-install/openSUSE_11.3/oss/ xencons=tty
textmode=1 '

Booting was succesful but not possible to upgrade:
Two error messages prevent me from upgrading:

The partitioning on disk /dev/sda is not readable by the partitioning
tool parted, which is used to change the partition table.
You can use the partitions on disk /dev/sda as they are.
You can format them and assign mount points to them, but you cannot add,
edit, resize, or remove partitions from that disk with this tool.
                           [OK] 

The partitioning on disk /dev/sdc is not readable by the partitioning
tool parted, which is used to change the partition table.
You can use the partitions on disk /dev/sdc as they are.

(x) New Installation 
( ) Update      SHADED-OUT, thus can not select !!!!

Strangely enough i can normally boot this XEN-image.
/dev/sda1 is my ext2 /boot mountpoint
/dev/sdb is my swap-disk
/dev/sdc i have a logical volume with /, /usr, /home, /opt, /var, /tmp.
/dev/sdd is a separate data-disk for /srv

So i can wipe the disk and do a fresh installation, but i can not do an
upgrade.... ;-O


Reproducible: Always

Steps to Reproduce:
1.
2.
3.
Actual Results:  
On existing (and perfectly running dom-U, I can not upgrade.


it might be related to 619461 ? (my sdc contains only lvm)
But otoh, sda1 only contains /boot, and the system fails to recognize this also.

I used the same procedure to upgrade other dom-U's, that only have one disk, instead of four on this machine
