KVM hosts on shared storage failure was accepted by mgmt server with the host state as Up, even though there was no primary/shared storage available on it. This patch offers a quick fix by throwing an exception in the storage monitor which connects storage pool on host. The failure is trapped by agent manager that disconnects the agent without any investigation. Based on Lab tests, KVM agent may take upto 2 minutes to attempt NFS mount when the storage is inaccessible (firewalled, or shutdown) before returning back with an error. It is safe to assume that this won't add pressure on mgmt server due to several reconnection attempts, and KVM agent would retry reconnection every 2 minutes. For such KVM hosts, where failure happens due to storage issues; they will be briefly put in Alert state but will be mostly be in Connecting state during which the KVM host attempts to mount/reconfigure NFS storage pool.
