This is hitting a lot of openstack users who chose 12.04 due to the announcement of backporting openstack to precise for 3 years: https://wiki.ubuntu.com/ServerTeam/CloudArchive
We fall into that category. It's pretty much impossible to use stock versions of dnsmasq and openstack in 12.04. This adds a significant burden to our team. This is a pretty serious problem that needs to find its way into 12.04 (precise), sooner rather than later, especially since it affects the recommended openstack essex configuration (vlan). It's causing our Windows Server instances to fatally lose their IP address config. This essentially makes our cloud unpredictably unstable, with instances coming and going randomly. Yes, there are potential workarounds (at least for openstack), but they're ugly: https://lists.launchpad.net/openstack/msg11696.html nova.conf # release leases immediately on terminate force_dhcp_release=true # one week lease time dhcp_lease_time=604800 # two week disassociate timeout fixed_ip_disassociate_timeout=1209600 Again, this needs to be fixed considering this is LTS, and considering that precise is supposed to be a solid foundation upon which to build an openstack cloud. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006898 Title: [SRU] dnsmasq fails at leasing issues when using vlan mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1006898/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
