Yes and maybe (we're doing it). The individual nova-api processes need to run on their own port though. nova-api --flagfile=/etc/nova/nova.conf --logfile=/var/log/nova/nova-api-<port1>.log --ec2_listen_port=<port1> nova-api --flagfile=/etc/nova/nova.conf --logfile=/var/log/nova/nova-api-<port2>.log --ec2_listen_port=<port2> you can fire up multiple nova-api processes with something like monit. Then you can load balance between them with something like haproxy.
