It looks like the ip for your hosts is in the 10./8 range which is probably
messing up routing and snatting. You will need to use a smaller range when
you create your vm network, say 10.75.0.0/16 and make sure you set
fixed_range to the same value in nova.conf

For metadata, you may have to set metadata_host (it sets this
automatically, but if you have multiple interfaces it could be getting the
wrong value) to the ip of the compute node on each compute host (and run
nova-api-metadata or nova-api on each compute host as well.
