[Fedora-xen] DomUdoes not start with Fedora-Xen-ia64

[jean-paul.pigache at bull.net]

We want to test Fedora-Xen-ia64, but Domu does not start.
Here is a short description of the problem, and below a more detailed 
description of the context.

DomU does not start:
-------------------

Xen30  has been installed from Aron Griffis repositories
(http://free.linux.hp.com/ãgriffis/agriffis-xen-ia64.repo)
on may the 24th.

File state:
    vmlinuz-2.6.16-%3.2232_FC6agriffis.3xen0
    xen.gz-2.6.16-%3.2232_FC6agriffis.3
    initrd-2.6.16-%3.2232_FC6agriffis.3xen0.img

Dom0 starts successfully but we have no useful root console, but
we can connect by ssh.
Root console displayes some messages but we have no prompt
to connect.

The DomU is a clone of Dom0.
But it does not start. DomU console does not open, and
we do not know why.

Any idea of what the problem could be ?

We will make another try with a newest kernel.

Background information: here is a summary of the problems we faced before 
getting Fedora-Xen running:

Fedora history :

Fedora Core 5:
----------------

Install with CDs built from iso files.

1- Graphic install KO and no switching to text mode.
So text mode only available because X server can not start:

   /var/log/Xorg.0.log:
    ....
        ATI Radeon X800 (R430) (PCIE), ATI Radeon X800 XL (R430) (PCIE),
        ATI Radeon X800 SE (R430) (PCIE), ATI Radeon X800 XTP (R430) 
(PCIE),
        ATI Radeon X850 5D4C (PCIE), ATI Radeon FireGL (R480) GL 
5D50(PCIE),
        ATI Radeon X850 SE (R480) (PCIE), ATI Radeon X850 PRO (R480) 
(PCIE),
        ATI Radeon X850 XT (R480) (PCIE),
        ATI Radeon X850 XT PE (R480) (PCIE),
        ATI Radeon X850 PRO (R480) (AGP), ATI Radeon X850 SE (R480) (AGP),
        ATI Radeon X850 XT (R480) (AGP), ATI Radeon X850 XT PE (R480) 
(AGP)
    (II) Primary Device is: PCI 01:01:0
    (II) ATI:  Candidate "Device" section "Videocard0".

    Fatal server error:
    xf86MapVidMem: Could not mmap framebuffer (0xfbfd0000,0x4000) (Invalid 

argument)

    My video card is:  01:01.0 VGA compatible controller: ATI Technologies 

Inc Rage XL (rev 27)

    Bypass proposed by Tony Luck  does not work.
    Patch of Bjorn Helgaas does not work too (not applicable because 
different sources)


NOTE: Same problem occurs with Rawhide ia64 from 27 April. When system is
running, X server
can not start for the same reason.



2-  hwclock can not be set when linux starts.

    hwclock: Open of /dev/efirtc failed, errno=2. No such file or 
directory.
    No usabel clock interface found.
    Cannot access the Hardware Clock in any known method.

Problem seems to be located in /etc/rc.sysinit file where hardware clock
is set before device creation (/sbin/start_udev step).
When hardware clock setting step is done after device creation, hwclock
gives right remanent time information.


3- After Dependencies checking and install beginning, an exception 
occurred.
Messages are:

    Traceback (most recent call last):
    File "/usr/bin/anaconda", line 1080, in ?
         intf.run(id, dispatch)
    File "/usr/lib/anaconda/test.py", line513 in run
       rc=apply(win,(self.screen, )+ args)
    File "/usr/lib/anaconda/textw/confirm_text.py", line 32  in __call__
      rc=present.requiredMediaMessage (intf, id.grpset)
    Attribute error: installData Instance has no attribute 'grpset'



Fedora weekly 05142006 :  install withCDs built  from iso files
---------------------------------------------------------------

Install in graphic mode does not work but install switches to text mode.

1-  Graphic install  still KO and switch to text mode.
( message 'module libXau.so.6 not found" in /tmp/X.log file'
I don't investigate this problem further more and hope that library name 
is 
correct.)


2- In Partionning step, when 'Create custom Layout' option is choosen
/boot/efi partition can not be created (Mounting point already in use).

    Partitionning has been made using 'Default layout creation' choice.


3-  In Network Configuration for Eth0, when 'Configure using DHCP' default
option is unset, given IP address  is declared as invalid.
Information  message is:

    'You must enter a valid IP address to continue.'

When active on boot is not selected and others network adapters not
configured, exception occurs in:

       anaconda.intf.run at line 938:
       ns1Entry.set (network.primaryNS
       NameError: global name 'network' is not defined.

4-  With  default configuration options for network adapters, setup goes 
on
and aborts


5-  After Dependencies checking and install beginning, an exception 
occurred.

    Traceback (most recent call last):
    File "/usr/bin/anaconda", line 1080, in ?
     intf.run(id, dispatch)
    File "/usr/lib/anaconda/test.py", line513 in run
       rc=apply(win,(self.screen, )+ args)
    File "/usr/lib/anaconda/textw/confirm_text.py", line 32  in __call__
      rc=present.requiredMediaMessage (intf, id.grpset)
    Attribute error: installData Instance has no attribute 'grpset'

Choice is then : OK to reboot, or Debug to enter in anaconda debugging 
mode.



Fedora weekly 04252006: install with http method (vnc askmethod)
---------------------------------------------------------------------

Come back on previous weekly because network configuration problems

1-  Graphic install  still KO and switch to text mode.

2- After language selection, an error occurrs:

    'Failed to read keymap information:
    Success'
    Only choice is OK and install goes on

Default options are kept and install ends.


Warnings :

- install from CDs built from iso files does not work in any case
- don't choose CD-Rom test: it leads to finally reboot
