Open Stack

Dear Steve,
Initially I faced the same issue with bexar release of Nova, when I
installed on 3 node cluster. on Ubuntu 11.04 server edition.
I am suggesting you to check the following.

1. On master node, check /var/lib/nova/instances/_base directory for files.
There you will find two executables. Copy these two files to the slave nodes
at respective directory i,e on slave node, /var/lib/nova/instances/_base
directory.
2.Change the group and owner ship of kvm and qemu.
3. Freshly create few instances on the controller node, you can see, your
instances running on the slave nodes.

Hope this will solve your problem on RHEL.. platform too.

do reply to me, once you are done with above steps.

--regards,
Praveen
