Make clear when a VM can't be deployed because a system DS is missing
|Target version:||Release 4.14|
If a VM has a vnet and image DS in different clusters, it can't even be instantiated.
If there isn't a host with enough capacity, the sched adds a message to the VM template:
Thu Feb 26 11:03:03 2015 : No host with enough capacity to deploy the VM
But when there isn't a system DS, the scheduler just says so in the sched.log file. There isn't a warning anywhere in the VM template or VM log
VM 2: No suitable System DS found for Host: 0. Filtering out host.
