How Has This Been Tested?

• Cluster 1: Host A
• Cluster 2: Host B

Using the environment above, I added the flexible host tag false to Host A, and tried to deploy a VM; which would always result on an incompatible host for Cluster 1. Prior to this patch, the CloudRuntimeException is thrown with the message No suitable host found for vm [...]. and Host B is not verified.

After applying this patch, the message No suitable host found for VM [%s] in %s. is still logged, however, Host B is verified for compatibility and the VM is deployed as expected.

How did you try to break this feature and the system with this change?
