I've not quite got this working right yet; after a failover, the secondary
hasn't connected the tap to the right bridge; I'm still trying to figure that
out.
at failover, colo will execute the qemu script(default: /etc/qemu-ifup)
to bring up tap
please check /etc/qemu-ifup
Further more, qemu downscript *must* be specified and the downscript is
needed to
reset you networking configuration which is configured by qemu-ifup script
following is a /etc/qemu-ifup and /etc/qemu-ifdown sample(both primary
and secondary)
root@master# cat /etc/qemu-ifup
#!/bin/sh
switch=br0
if [ -n "$1" ]; then
ip link set $1 up
brctl addif ${switch} $1
fi
root@master# cat /etc/qemu-ifdown
!/bin/sh
switch=br0
if [ -n "$1" ]; then
brctl delif ${switch} $1
fi

+
+ /usr/local/sbin/iptables -t mangle -D PREROUTING -m physdev --physdev-in \
+ $virt_if -j SECCOLO --index $index
I think this is new in this version; don't you still need the SECCOLO
mangle to fixup the sequence number of packets in existing connections so they
match the numbers that the PMY used?
the kernel part code will help us to adjust sequence once we
initialized the
seq offest to kernel, so after failover, we don't need the SECCOLO mangle
anymore
Best regards.
