Hello,
I am going forward with trying to implementing neutron in XenServer.
Looking in documentation that is possible with DevStack.
https://wiki.openstack.org/wiki/QuantumDevstackOvsXcp But there is one
catch, in section, where you enable services(ENABLED_SERVICES) there is
two more services, which isn't in havana release: q-agt and q-domua. So,
if I am right, this two services make possible to run necessary neutron
commands from domU in to dom0. So, where I can get this services? Or
maybe all this is included in neutron-plugin-openvswitch-agent package,
just need to configure it right?
In /etc/neutron/rootwrap.conf is xenapi section, so I suppose that it is
required to run neutron + XenServer. And there is
/usr/bin/neutron-rootwrap-xen-dom0 script, which login to XenServer and
run commands.
And additional question:
Is anyone trying to live migrate with OpenStack + neutron + XenServer
setup? I can't live migration, got error:
http://paste.openstack.org/show/55683/
Maybe this is because my neutron setup is not working completely, but
maybe this is bug in live migration ...
Thanks.
