[Xen-users] vif dmesg spam

[Mark Benson <md.benson@xxxxxxxxx>]

Hi,

Xen 4.1 with XAPI on a Debian 7.8 box recently updated and rebooted.

I went to check my dmesg log to diagnose a NFS mounting issue this
morning and found it was a wall of this...

[316943.288669] vif1.0: no IPv6 routers present
[316943.312673] vif2.1: no IPv6 routers present
[316992.280673] vif1.0: no IPv6 routers present
[316992.312663] vif2.1: no IPv6 routers present
[317338.280667] vif1.0: no IPv6 routers present
[317338.296664] vif2.1: no IPv6 routers present
[317387.288666] vif1.0: no IPv6 routers present
[317387.304677] vif2.1: no IPv6 routers present
[317733.288687] vif1.0: no IPv6 routers present
[317733.304664] vif2.1: no IPv6 routers present
[317782.280669] vif1.0: no IPv6 routers present
[317782.312674] vif2.1: no IPv6 routers present
[318128.288679] vif1.0: no IPv6 routers present
....
[569397.288672] vif1.0: no IPv6 routers present
[569397.320666] vif2.1: no IPv6 routers present
[569743.288668] vif1.0: no IPv6 routers present
[569743.320677] vif2.1: no IPv6 routers present
[569792.296674] vif1.0: no IPv6 routers present
[569792.328730] vif2.1: no IPv6 routers present
[570138.288671] vif1.0: no IPv6 routers present
[570138.320666] vif2.1: no IPv6 routers present
[570187.296674] vif1.0: no IPv6 routers present
[570187.328673] vif2.1: no IPv6 routers present

This has filled the entire dmesg log.

Which means dmesg isn't much use right now! Any idea where all that
came from? We run no IPv6 services on our network so it's correct,
there aren't any IPv6 routers, but that seems an excessive number of
notifications!

Any ideas?
