Hello Andrew, using NFS for live migration I found strange behaviors too. To be more specific, I noted that at a certain point I couldn't boot any new VM. Live migration in itself was fine provided that I didn't reach a number of concurrent VMs; the problem was that after a number of VMs (in my

Re: [Openstack] How does VMs connect to cinder created Volumes ?
