Hi Dan,

that normally should not happen. Presuming you are running Neutron, it may be 
two things – either your DHCP agent died and the instances could not renew 
their IPs, or the DHCP client inside them died, or as third variant, your 
RabbitMQ bus is broken and the DHCP agents don’t have actual data.

Subject: [Openstack] VMs lost IP after running for few days on OpenStack 
Liberty.

 

Hi, Experts,

  Recently I found VMs on my OpenStack Liberty will get lost their private IP 
address after running normally for 1~2 days("#ip addr" will show no IP 
associated with eth0 for example), thus could not be ssh login anymore. But 
after console login to the instances from Horizon and restart the network(# 
service network restart), everything returns normal and they could be ssh login 
again( eth0 now gets it IP). From nova-compute.log I see there are messages 
like "NeutronClientException: Authentication required". But the keystone 
service runs normally and no other service are affected.

  Any hint about the problem? Thanks a lot!

 Cheers, Dan
