Add Fake virt driver support
nova fake virt driver can be used to simulate running arbitrarily large
number of VMs. When the fake virt driver is selected, all other arbitrary
limits are disabled (quotas, scheduler limitations) as well. The fake
virt driver can be selected by adding the following line to your localrc
VIRT_DRIVER=fake
This setting can be used to do simulated large scale (as defined by
number of VMs) testing (such as boot 500 VMs at once) inside a single
devstack instance.
