F7 x86_64 Xen - Can't start xend - wrong ELF class
by Chris Tyler
I've been using Xen under FC6 for some time. I have an FC6 domU that I
want to migrate to a new box, which is running F7 x86_64. I'm having an
awful time getting Xen up on the new box; the problem that I'm seeing
looks like it may be a FAQ but I haven't find any other mentions of it.
I have the hypervisor and dom0 running fine, but I can't run xend:
-----------------------------------------------------------------
# service xend start
Starting xend: Traceback (most recent call last):
File "/usr/sbin/xend", line 34, in <module>
from xen.xend.server import SrvDaemon
File "/usr/lib/python2.5/site-packages/xen/xend/server/SrvDaemon.py",
line 20, in <module>
import xen.lowlevel.xc
ImportError: /usr/lib/python2.5/site-packages/xen/lowlevel/xc.so: wrong
ELF class: ELFCLASS32
(...snip...)
ImportError: /usr/lib/python2.5/site-packages/xen/lowlevel/xc.so: wrong
ELF class: ELFCLASS32
.Traceback (most recent call last):

line 20, in <module>
import xen.lowlevel.xc
ImportError: /usr/lib/python2.5/site-packages/xen/lowlevel/xc.so: wrong
ELF class: ELFCLASS32
-----------------------------------------------------------------
Looks like that file is expected to be a 64-bit binary but is 32-bit
(?). Not sure how to get a 64-bit version; the file is owned by package
'xen' (3.1.0-0.rc7.1.fc7) but the only version available appears to be
i386.
Any pointers would be appreciated!--

Re: [Fedora-xen] Can't find CDROM after installing Win2k
by Songtao Liu
Hi,
I have also encountered this problem before in Fedora6 :) but I use Windows
image, not CD, here is my steps, maybe will give you some hints
1. Open the VM and do it via wizard step by step.
2. After the Virtual Machine Console pops up, install the OS as normal
installation.
3. When the system says to press F6, make sure to Press F5 and select
"standard PC" and continue.
4. Choose to format the C:\ partition in FAT file system format because Linux
isn't compatible with NTFS kernel modules(in fact it works). Mounting or
writing files to Xen guest image may not be as straight-forward if you were to
format in NTFS.
5. After reboot, we should fix the WinXP image in order to avoid the coming
problem by installation.
#losetup -f
#losetup /dev/loop0 /xen/winxp
#kpartx -av /dev/loop0
#mount /dev/mapper/loop0p1 /mnt/winxp
#mount /WinXPimage/winxp.iso /mnt/tmp/
#cp -prv /mnt/tmp/I386 /mnt/winxp
#umount /mnt/winxp
#umount /mnt/tmp/
6. Restart the guest OS with 'xm create winxp'. When the 'file needed' dialog
window comes up, input the path as c:\i386. Then everything should be smooth.
Maybe you should input the path c:\i386 many times, as it the path will not be
remembered.
Hope it helps.

Live migration of full virtualized guests
by Laszlo BERES
Hello there,
I am totally sure I read months ago that the above is not supported, but
now I don't find infos about it. So, is it true? Is any kind of full
virtualized guests' migration possible in Fedora or RHEL5?
Thanks,
Laszlo

My best suggestion is that X isn't using acceleration in the Xen case.
Try comparing the output of xdpyinfo command and also looking at
/var/log/Xorg.0.log in the Xen and non-Xen cases.

RE: [Fedora-xen] Problem installing xen guest on Fedora Core 7
by Formoso, Travis
Mike -
Is there a way to do this w/out using Virt-manager? I do not have a GUI installed on the server and the IT team does not put them on the servers.
If not I guess I can install the GUI and do the installs if I have to.
Thanks,
Travis

I still don't understand. This is in a guest? In dom0?

FC7 Xen not running properly on HP Compaq dc5750 MT
by König, Ralf
Hi all,
I have problems running the FC7 XEN kernel (2.60.20-2925.11.fc7xen) properly on a HP Compaq dc5750 MT machine.
The udev service does not seem to start up, the CDROM is not working and I receive a lot of ata2.00 errors, similar to those described here
http://lists.debian.org/debian-amd64/2007/04/msg00016.html
If I am using the latest 2.6.21 kernel (2.6.21-1.3194.fc7) without XEN support these problems do not occur.
However, this is not an alternative to me, since I need XEN. So what can I do? Is there a realistic possibility to compile a 2.6.21-1.3194 XEN enabled kernel or what other solutions to this problem do exist?
