Error initializing xen_net

Error initializing xen_net

[Matt Ayres]

Hi,

This is on a 2.0.4 system.  When booting a VM I receive the following on
boot:

xen_net: Initialising virtual ethernet driver.
xen_net: Failed to connect all virtual interfaces: err=-100
...
NET: Registered protocol family 17
Bridge firewalling registered
<hangs>

I have tried on both 2.4 and 2.6 xenU kernels.

This seems to have affected all domains... it also prevents them from
being shutdown properly (xm destroy must be used).  Is this a known
issue that is fixed in -testing?

This shouldn't be happening...

Could you have a look for clues in your xend.log and xend-debug.log (post them 
to the list if you're having trouble and they're not too long).

Is there any chance you have a stale set of tools from another version of Xen?

Cheers,
Mark

This sounds like either xcs or xend is becoming unresponsive.

I've only seen this error occur when the NETIF messages aren't being 
delivered correctly.

If you can reproduce this, it would be very useful to have the output of 
xcsdump.  It'll be large so feel free to send it to me off list or post 
it somewhere.

Regards,
Anthony Liguori

To answer everything at once:

1) Yes the tools are synced with the version of Xen.  I always keep them
together.
2) I tried to look into 'how' to run xcsdump... figured it was a binary,
but I can't find it.  How do I go about getting its output?
3) Just to throw in... i've still having the xend not restarting problem
as previously reported by anothers on this list.  It will start once on
boot, then if I stop it and try to start it xfrd will start, but xend
will not.  xend.log and xend-debug.log does not show any info.
4) As far as oddities in xend-debug.log .. not sure if these are or not,
but looked interesting.

No timestamps in xend-debug.log so it's really hard to figure out what
was what.  Network card is an E1000.

I suspect the failure to start the domain is simply a problem in your
config file. Perhaps do a dry run and post the sxp config.
