Thanks,
I believe I've had some issues due to fiddling around in the database
too much. I've dropped the db, synced it again and now it works.
thanks a lot.

In Essex, I've seen issues like this if your fixed_ips table in the nova
database has multiple entries for the same address (even if some of
those entries are marked delete=true, though this has been fixed in
Folsom). If you feel confortable, take a look at the fixed_ips table to
see if anything looks odd. The dnsmasq conf files are generated
directly from this table.

Hi openstack-guys,
using the latest essex release from ubuntu packages, I see a weird
nova-network behaviour (flat networking):
nova.conf:
--flat_interface=eth0
--flat_network_bridge=bridge_130
--flat_network_dhcp_start=192.168.32.130
--flat_injected=False
nova-network runs on a different host as nova-compute.
when I provision a VM, it all looks good (no errors in the logs),
but the VM doesn't get an IP address. I've tcpdumped and verfied
that the dhcp request reaches the correct interface of nova-network.
now looking into dnsmasq I found this in the syslog:
Jul 22 22:29:27 localhost dnsmasq-dhcp[3107]: read
/var/lib/nova/networks/nova-bridge_130.conf
Jul 22 22:29:50 localhost dnsmasq-dhcp[3107]:
DHCPDISCOVER(bridge_130) 192.168.122.96 fa:16:3e:60:92:a6 no address
available
bummer. so I checked to see why this happens, and it turns out, that
/var/lib/nova/networks/nova-bridge_130.conf is empty. I assume there
should be the mac to IP mapping, written by nova-network, but
although the file exists, it doesn't have content. nova-network
doesn't complain about any issues with this file, the file system
permissions allow the nova-user to write there, so I do not quite
know how to handle this.
Any hints would be very welcome.
Thanks a lot
wolfgang
