cluster nodes. Not going to try and describe all these changes. Note that I have not back ported this into the old assign wrapper. We move inexorably forward. Worth mentioning: * Users get VMs only on shared hosts. * Multiple experiments from multiple projects can share a node. * Nodes that are acting as shared hosts are in a holding experiment and have a tag in the reserved table. All of the links in the experiment are tied together in one giant super vlan. We then multipleax over that using our standard mechanisms (veths, vlans, whatever). * Lots of complication in the link setup code for dealing with links between a virtual node on a shared node, and a private physical node. Requires additional vlans and trunking between those interfaces. To make life easier, all of the links in the afore mentioned super vlan are trunked in dual mode. * I had to change Mike's code that does the encap determination, since openvz nodes cannot do veth encap. I add some new osfeatures (veth-ne, veth-en, and vlans). * On and on and on ...
