Problem with quantum

asked 2012-01-12 20:14:25 -0500

Hi All: I send this post to ask you . I cannot run my instances in my server with nova + openvswitch and quantum.

This is one of the error that I found. 2012-01-12 14:45:52,245 AUDIT nova.compute.manager [5e535ea4-4d48-4d36-b69c-1246e9f68994 admin meli] instance 9: starting... 2012-01-12 14:45:52,391 DEBUG nova.rpc [-] Making asynchronous call on network ... from (pid=2552) multicall /usr/lib/python2.6/dist-packages/nova/rpc/ 2012-01-12 14:45:52,391 DEBUG nova.rpc [-] MSG_ID is 9ad145ef497141ff8212a9f38d9be828 from (pid=2552) multicall /usr/lib/python2.6/dist-packages/nova/rpc/ 2012-01-12 14:45:53,114 DEBUG nova.compute.manager [-] instance network_info: |[[{u'injected': True, u'cidr': u'', u'multi_host': False}, {u'broadcast': u'', u'ips': [{u'ip': u'', u'netmask': u'', u'enabled': u'1'}], u'mac': u'02:16:3e:6a:88:78', u'vif_uuid': u'19b1e87c-ffac-4fcb-ace3-525dd92d3e40', u'dns': [u''], u'dhcp_server': u'', u'gateway': u''}]]| from (pid=2552) _run_instance /usr/lib/python2.6/dist-packages/nova/compute/ 2012-01-12 14:45:53,333 DEBUG nova.virt.libvirt_conn [-] instance instance-00000009: starting toXML method from (pid=2552) to_xml /usr/lib/python2.6/dist-packages/nova/virt/libvirt/ 2012-01-12 14:45:53,334 DEBUG nova.utils [-] Running cmd (subprocess): ip link show dev tap19b1e87c-ff from (pid=2552) execute /usr/lib/python2.6/dist-packages/nova/ 2012-01-12 14:45:53,341 DEBUG nova.utils [-] Result was 255 from (pid=2552) execute /usr/lib/python2.6/dist-packages/nova/ 2012-01-12 14:45:53,342 DEBUG nova.utils [-] Running cmd (subprocess): sudo ip tuntap add tap19b1e87c-ff mode tap from (pid=2552) execute /usr/lib/python2.6/dist-packages/nova/ 2012-01-12 14:45:53,353 DEBUG nova.utils [-] Running cmd (subprocess): sudo ip link set tap19b1e87c-ff up from (pid=2552) execute /usr/lib/python2.6/dist-packages/nova/ 2012-01-12 14:45:53,365 DEBUG nova.utils [-] Running cmd (subprocess): sudo ovs-vsctl -- --may-exist add-port br-int tap19b1e87c-ff -- set Interface tap19b1e87c-ff external-ids:iface-id=19b1e87c-ffac-4fcb-ace3-525dd92d3e40 -- set Interface tap19b1e87c-ff external-ids:iface-status=active -- set Interface tap19b1e87c-ff external-ids:attached-mac=02:16:3e:6a:88:78 from (pid=2552) execute /usr/lib/python2.6/dist-packages/nova/ 2012-01-12 14:45:53,374 DEBUG nova.utils [-] Result was 1 from (pid=2552) execute /usr/lib/python2.6/dist-packages/nova/ 2012-01-12 14:45:53,375 ERROR nova.exception [-] Uncaught exception (nova.exception): TRACE: Traceback (most recent call last): (nova.exception): TRACE: File "/usr/lib/python2.6/dist-packages/nova/", line 98, in wrapped (nova.exception): TRACE: return f(args, *kw) (nova.exception): TRACE: File "/usr/lib/python2.6/dist-packages/nova/virt/libvirt/", line 597, in spawn (nova.exception): TRACE: block_device_info=block_device_info) (nova.exception): TRACE: File "/usr/lib/python2.6/dist-packages/nova/virt/libvirt/", line 1164, in to_xml ...

It seems sudo is unable to execute ovs-vsctl:

(nova.compute.manager): TRACE: Stderr: 'sudo: no tty present and no askpass program specified\n'

Since these commands are being executed without a tty, my guess is that ovs-vsctl should be added to the sudoers file with the NOPASSWD option.

Salvatore is correct. Could you clarify what distro and version you are running on ? I thought we had fixed the issues of OVS not being in the sudoers file for more recent version of Ubuntu. If not, we'll have to contact them again.
