Hi, I have a 3 node Folsom with Quantum setup. One is a controller node, one is a quantum networking node and the other is a KVM compute node. I see that on the Controller and Compute nodes, the memory usage is very high, based on the free command output. I have about 8gb RAM in the controller node and 32gb in the Compute node. For example the compute node returns this: root at openstack-kvm1:~# free -m total used free shared buffers cached Mem: 32173 31619 553 0 115 29494 -/+ buffers/cache: 2009 30163 Swap: 0 0 0 root at openstack-kvm1:~# I am not sure if my interpretation if the output is wrong or if I have a genuine memory issue. Any pointers will help. Thanks, Balu -------------- next part -------------- An HTML attachment was scrubbed...
