Hi folks,
I have a server where I have solved the well known problem with a bonding
interface as netdev on Xen/Centos 5.x (current: 5.2) - the problem is, that
in mode=1 (active-passive) the slave interfaces are de-/activated round
robin at least once a second. "network-bridge stop netdev=bond0" stops
this
nonsense and makes the bonded interface work well again.
I had to do change 3 entries to get it running:
1. in /etc/xen/xend-config.sxp I set "(network-script
''network-bridge
netdev=bond0'')" - that is explicitly naming the
''physical'' interface.
2. in /etc/libvirt/qemu/networks/default.xml I have set xenbr0 to be the
default bridge.
3. in /etc/sysctl.conf I added "net.ipv4.conf.all.proxy_arp = 0"
Now I have set up a second server exactly like the first (even with the
same NIC chips, t3), but this time the problem persists: the slave
interfaces start switching permanently as soon as the network-bridge script
has moved bond0 to the bridge.
I have looked and tested for days now, but I do not come to any result. My
first thought was that with the first server setup I forgot to document
some little change I made. So I sought the web and compared my config
files, but I cannot find anything.
I need help in this, please! I am stuck within the problem, I do not see
anything at all any more. There must be something I overlook - any hint or
help is greatyl appreciated.
Dirk
