Hello,
I have a question regarding ARP updates.
Network Setup: venet with proxy arp.
When movin a VE from one host to another (via DRBD: node1:shutdown,
switch drbd , node2:start) the IP/MAC combination needs to be
re-advertised so that the ARP caches are flushed. This can be done
with
"sendarp". Otherwise the host is not reachable.
Is this integrated into the OpenVZ command utilities ? How can I
integrate this command that it alsways is running on:
1) Every VE start
2) Every IP add
My Idea:
Custom add_net and vps.mount hook scripts, however because this such a
general issue, I thing someone already found a elegang solution for
this
IIRC this is already implemented in the normal vz instance startup
scripts. If you do a live migration with custom tools you may need to
implement this yourself.
