Fedora9 and HP ML350
by Alroger L. Gomes F.
Hello everyone.
I've just installed Fedora9, on a HP Proliant Server ML350 with
SmartArray E200i (cciss driver), hoping to use the latest Xen features.
When I boot into the kernel-xen, it gets up to the following line and
reboots itself in an endless loop.
XEN is relinquishing VGA console
It does not generate any output on /var/log/messages nor /var/log/xen/*.
Any ideas?

RE: Newby Help
by Walter Coole
With a lot of help and trying things without much of a clue, I think
I've gotten virt-install to create a machine image, but that machine
boots into an Anaconda session that hangs. The error says:
Unable to read package metadata. This may be due to a missing
repodata directory. Please ensure that your install tree has
been correctly generated. Cannot open/read repomd.xml file
for repository: anaconda-base-200610172015.x86_64
Can anyone tell me where this repomd.xml file is supposed to be? Or a
way to validate my install tree? Or a better way to build an install
tree than turning wget loose on
download.fedora.redhat.com/pub/fedora/linux/core/6/x86_64 ?
I've gone through a couple of sets of instructions that have failed for
me in a variety of ways that I don't seem to be able to cope with.
Since someone seems to be able to use Xen, I'm apparently doing
something clueless that isn't covered by those instructions. If someone
can provide some guidance, I'd be happy to start over from scratch.
Extremely grateful for any hints,
Walter

Newby Help
by Walter Coole
I'm having trouble getting Xen up on Fedora 6. Following the
instructions at http://fedoraproject.org/wiki/FedoraXenQuickstartFC6 ,
I've got xend running, but haven't gotten a viable image running.
I tried (per the above) virt-manager. I guessed that
http://download.fedora.redhat.com/pub/fedora/linux/core/6/x86_64/os/ was
a suitable install tree, but when the installer (Anaconda, I guess) gets
to some point (it varies with each attempt) it stalls, sometimes
complaining about not getting a file.
I also tried xm, but haven't figured out how to deal with the error:
Cannot open root device "sda1"
Virsh throws a different error:
Domain not found: xenUnifiedDomainLookupByName
I'm befuddled by having tried several different sources, each of which
said "it's soooo easy", but failing to provide sufficient information to
get me past these issues, so I'd be grateful if someone could point me
to instructions geared to the meanest understanding.

root element in config file
by Gerrard Geldenhuis
Hi
I am trying to put together a working xml file to create a new
domain....
The root element is baffling me a bit.
from the http://libvirt.org/ website
root: the root filesystem from the guest viewpoint, it may be passed as
part of the cmdline content too
My current value is <root>/dev/xvd</root> but that was automatically
created by satellite which I am trying to adapt for my own use.
When I do a virsh create config file I get the following error:
libvir: Xen Daemon error : POST operation failed: (xend.err "Error
creating domain: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF
image has no shstrtab\\n')")
If someone would'nt mind explaing a bit more what this root file system
is...

RE: [Fedora-xen] Possible Stupid Question...
by Dustin Henning
David,
This is probably a "something stupid" related to Linux more
than Xen. It sounds like the system isn't booting at all, and the most
likely cause is that the drivers necessary for the SAS are not in the
kernel. Linux picks appropriate drivers for the machine you install on and
then all updates use those drivers, so when you move to new hardware, it
just doesn't work. If you copy the kernel and modules from the working
machine to the machine that didn't work when you did your dd_rescue, it
might boot with them, however, when it comes time to update, you will need
to manually compile your new kernels instead of using the standard automated
update method, i.e. do the standard update, ut then do a custom compile and
boot to the custom kernel, not the one from the standard update, as it ill
crash, but the custom compiled one will be compatible with the other changes
made by the automatic update. This is far from detailed and complete, as it
has been a while since I have dealt with that kind of thing, but I most
often experienced it switching from "Compatibility Mode" SATA to AHCI on
some machines that I didn't want to rebuild. I n your case, a rebuild on
the problem machine is probably a better option, as you can then migrate
whatever you want however you want to a clean machine with no thorn in its
side.

Subject: [Fedora-xen] Possible Stupid Question...
Hey guys,
Been loving Xen and playing around with it for awhile now but recently tried
something new and had a really weird result, not sure if it is at all
related to Xen so I'm gonna ask here.
1. I have a SATA based Xen x64 machine running a para-virtualized x64 VM,
that VM is written out to an LVM Partition. /dev/vgmachine/lvVM
2. I shut down that VM and then dd_rescue it over to another machine. (With
the same LVM setup)
3. The other machine is running the same exact host OS but has SAS based IO
instead of SATA.
4. When I bring up the Xen machine on the SAS host the whole computer gets
hosed. I see SAS controller errors and I have to hard power the machine.
I'm building a new Xen machine on the SAS host now and it doesn't seem to be
causing trouble, did I do something stupid in assuming that I could move a
Para-virtualized machine from one type of IO to another?

iwlwifi with 2.6.21-7.fc7xen
by Tomáš Kouba
Hello,
is anybody on this mailing list using iwlwifi driver with fedora and xen
kernel?
I have downloaded sources, untarred but it doesn't compile with error:
include/asm/fixmap.h: At top level:
include/asm/fixmap.h:110: error: expected declaration specifiers or
‘...’ before ‘maddr_t’
In file included from include/asm/elf.h:52,
from include/linux/elf.h:7,
from include/linux/module.h:15,
from
/root/iwlwifi/iwlwifi-1.2.25/compatible/iwl3945-base.c:31:
The problem is this line:
extern void __set_fixmap(enum fixed_addresses idx,
maddr_t phys, pgprot_t flags);
I am not very sure what gcc complains about maddr_t.
Thanks for any help.
