[Xen-devel] Possible bug with two networks (broken network after 16th VIF)
Hi,
Last days I have noticed my DomU''s broke semi-randomly, I was able to
trace this to the following. In my state file I still had an
''network'',
a thing that wasn''t used.
The first 15 VIFs were all added to xenbr0. The 16th ended up the
''next''
bridge.
xen01 cgi-bin # brctl show
bridge name bridge id STP enabled interfaces
klant1_network 8000.feffffffffff no vif16.0
xenbr0 8000.0019b9ebd3f6 no peth1
vif1.0
vif2.0
vif3.0
vif4.0
vif5.0
vif6.0
vif7.0
vif8.0
vif9.0
vif10.0
vif11.0
vif12.0
vif13.0
vif14.0
vif15.0
After manually removing this ''bridge'' from the statefile it
looks:
xen01 cgi-bin # brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.0019b9ebd3f6 no peth1
vif1.0
vif2.0
vif3.0
vif4.0
vif5.0
vif6.0
vif7.0
vif8.0
vif9.0
vif10.0
vif11.0
vif12.0
vif13.0
vif14.0
vif15.0
vif16.0
I suspect something is overflowing. For me it works now, but it might
worth to investigate this behavior.
In any case; after the 16th device the computer doesn''t want to reboot,
and I see udev issues with vif-bridge / xen-hotplug-cleanup abnormal exit.
The system hangs on remounting remaining filesystems readonly.
Stefan
