Hi, what in nova.conf connection_type stands for ? I only found that info http://nova.openstack.org/api/nova.virt.connection.html#module-nova.virt.connection "This could benova.virt.fake.FakeConnection <http://nova.openstack.org/api/nova.virt.fake.html#nova.virt.fake.FakeConnection>in test mode, a connection to KVM, QEMU, or UML vialibvirt_conn, or a connection to XenServer or Xen Cloud Platform viaxenapi. " I've only been able to make nova-compute register itself to nova-scheduler only after I set --connection_type=fake while I use qemu that libvirt connects to. When that flag was set connection_type=libvirt, I was unable to spawn a qemu instance (ttlyinux) with connection_type=fake it work thanks guys Razique -- Nuage & Co - Razique Mahroua razique.mahroua at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
