Re: Re; [Xen-users] Ethernet has Alzheimers

[Gareth Bult <gareth@xxxxxxxxxxxxx>]

Ok,

I've a sneaking suspicion after a couple of tests that this may be the cure.

It needs to go into /etc/xen/scripts/xen-network-common.sh

I notice over recent versions there have been a number of people commenting on 
what looks like the same problem, nobody seems to have a definitive fix.

My other fix (to date) it to insert static ARP entries with;

arp -s <address> <hwaddr>

This also seems to be working ...

Many thanks,
Gareth.

Not sure if this is the problem, but I think you need to turn ARP off on
your bridge interfaces. Something like:

"
ip link set xen-br0 arp off
"

or, if you prefer ifconfig:

"
ifconfig xen-br0 -arp
"

should do the trick. On my system, xen-br0 would sometimes respond to
arp requests, even though it had no IP address of its own.
