[Xen-users] weird mtu problem with xen3.1 + bonding
Hi list,
[Second try, couldn't find my original posting in the archives so it
might have been eaten by a spamfilter]
I'm experiencing a weird problem which seems to be caused by the
network layer. What happens is that our domU is sending out ethernet
frames with sizes >MTU, which is not supposed to happen.
The setup is as follows:
peth0 \ / vif0.0 -- dom0
bond0 -- bobr0
peth1 / \ vifN.0 -- domU
where bond0 is a HA bonding interface, and bobr0 is a bridge.
All these interfaces have mtu <= 1500 in both the dom0 and domU, and
no MTUs set for specific routes, so I'd expect frames coming from
those interfaces to behave nicely.
Versions: xen 3.1.0
Dom0 kernel: 2.6.18-xen [from xen-3.1.0-install-x86_32p.tgz]
DomU kernel: 2.6.18-xen [the same]
I've tried lowering all MTUs in the system, but I can't seem to be
getting it to work.
Anyone with good ideas?
Cheers,
Jasper
