Resize doesn't apply the hypervisor_type filter in choosing the migration target

[Alessandro Pilotti]

I'm testing nova resize in an environment with 2 mixed compute hosts. By testing the resize feature, it looks like the hypervisor_type image filter is not respected and migration is attempted to other hypervisor types as well.

Here are the steps to generate the issue:

1 Compute node: Hyper-V
2 Compute node: KVM

glance image-create --property hypervisor_type=hyperv --name "Ubuntu Server 12.04" --container-format bare --disk-format vhd < UbuntuServer1204.vhd

nova boot --flavor 1 --image "Ubuntu Server 12.04" vm1

(Instance boots as expected on Hyper-V)

nova resize vm1 2

Nova tries to migrate the vm1 instance from Hyper-V to KVM.
