> The same bug was reported in CLOUDSTACK-3839 which has been determined to be a
> UI issue but the problem is with the addHost API and Xenserver hosts 6.1/6.2. 
> When a freshly provisioned 6.1/6.2 host is added to cloudstack it initially
> goes into 'Alert' state thereby failing the storage pool creation subsequently.
> StoragePool addition requires the hosts to be in Up state. But a minute or two
> later the Xenserver host automatically moves back to Up state after which
> storage pool addition can occur
> When the host is added to cloudstack:
