Hi List,
so far i didn't got any further with my issue. I'm not sure if it is a
bug but i tried to track down the problem. First: I applied the patch
located under:
http://lists.xensource.com/archives/html/xen-users/2006-05/msg00224.html
and also used the newest pciif.py from xen-unstable. No effect. I then
did the following. I debugged the pciif.py and printed the config value in:
def get_param(config, field, default=None):
and compared them during startup and reboot. This revealed a huge
difference. During the startup the config had the following values:
sxp:(dev (domain 0x0) (bus 0x02) (slot 0x05) (func 0x0))
but during restart everything was empty. So i walked up the stack and
looked into XendDomainInfo.py which was next in the stacktrace. Here
the method:
def restart(self, rename = False):
which seems responsible for creating the 'config' (but i'm not 100%
sure) through a call to:
config = self.sxpr()
So the method 'sxpr()' seems to be in charge. sxpr() seems to round trip
the old config values and overwrite some with new values from the config
file (at least IMHO). But the pci configuration seems neither to be
round tripped nor to be read in again. So this seems to be the cause of
my problem. Now the question: Am i right or am i wrong? I'm no xen
expert so there's a big chance I'm just missing the point.
please enlighten me.
best regards
Sebastian

Hi Mike,
thanks very much for the help but unfortunatly it didn't worked out. I
have tried the the 3-item value for the pci-option and get the same
error.
But now i found out that "xm info" will give a very detailed info of my
environment. So here it is:

Hi List,
Hi Sebastian,
i have the Xen-kernel from backports.org running on my debian stable
machine. It works quite well but as i reboot a DomU with a physical NIC
assigned to it (using the "pci="-option) it won't restart. I did a
little googling and came across the following error:
http://lists.xensource.com/archives/html/xen-users/2006-05/msg00107.html
But this don't seem to be my exact problem since the error message in
xend.log is different. Is this a bug in xen or am i missing something.
Any hint's or help would be greatly appreciated. Maybe i'm just too
dumb
to get it right. I've attached my config file and a stacktrace to
this mail.
Thanks very much in advance
Sebastian
------------- config file -------------
kernel = "/boot/vmlinuz-2.6.16-2-xen-686"
ramdisk="/boot/initrd.img-2.6.16-2-xen-686"
memory = 64
name = "wwwserver"
#vif = [ '' ]
pci = ['0000:02:05.0']
I seem to remember that, at that time, the python code was looking
for a list of 3 items. That pci option has 4. Try "pci =
['02:05.0']" instead.
Hope that helps,
Mike Wright
