New issue 1071 by [email protected]: LXC should setup NIC IPs, if
configured in ganeti
https://code.google.com/p/ganeti/issues/detail?id=1071
With the LXC hypervisor, it is possible to setup NIC configuration (IP,
gateway) without the need to delegate this task to the OS-interface. It has
the advantage, that one could drop the net_admin capability.
I quickly hacked my Ganeti installation (2.14) and ignored IPv6 completely
(assuming the gateway is on the 1st NIC):
--- old/hv_lxc.py 2015-03-09 10:37:19.000000000 +0100
+++ new/hv_lxc.py 2015-04-21 15:37:22.000000000 +0200
def _CreateConfigFile (self, instance, sda_dev_path):
...
...
out.append("lxc.network.hwaddr = %s" % nic.mac)
out.append("lxc.network.flags = up")
+ if nic.ip and nic.netinfo:
+ out.append("lxc.network.ipv4 = %s/%s" % ( nic.ip,
nic.netinfo['network'].split('/')[1] ) )
+ if idx == 0:
+ out.append("lxc.network.ipv4.gateway = %s" %
nic.netinfo['gateway'])
Perhaps this is useful for someone else.
Thanks, Sascha.
