Open Stack

Hello

I've built an Openstack all-in-one using OVS-DPDK via Devstack.

I can launch instances which use the "m1.small" flavour (which I have modified to include the hw:mem_size large as per the DPDK instructions) but as soon as I try to launch anything more than m1.small, I get this error:

My Hypervisor is reporting 510.7GB of RAM and 61 vCPUs.

Build is the latest git clone of Devstack.

Thanks
