Can't ping between vms on different compute nodes

Using diablo-stable with multi_host it seems that vms cannot ping other vms that are hosted on different compute nodes using addresses allocated from fixed_range (in this case 10.0.0.0/24). A vm can be pinged at this address from its compute node or other vms on the same compute node. Is this expected?

This was my fault. eth1 was not being forced up.
