Hi everyone,
	
	Currently, disk.swap(the swapfile of instance) is created on the instances_path(deflaut : /var/lib/nova/instances/<vm-uuid>). Maybe we should add configuration item in nova.conf to set virtual machine swapfile location. With such a feature enabled, swapfiles can be placed onto a specified storage, e.g. a SSD, seperatedly.

Thanks,

Zhou Yu
