   ##### SUMMARY
   <!-- Explain the problem/feature briefly -->
   KVM hosts are being rebooted by `kvmheartbeat.sh` when the NFS-server that is being used as a primary storage becomes unreachable.
   
   I'd like to propose change behavior of `kvmheartbeat.sh`, as it's not necessary to reboot a whole host when only one of VMs is having difficulties while other VMs are working fine with other storages.
   
   ##### STEPS TO REPRODUCE
   <!--
   For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
   
   For new features, show how the feature would be used.
   -->
   It's easy to reproduce: just deploy a VM with a volume on an NFS-based storage, break NFS and wait.

   ##### EXPECTED RESULTS
   <!-- What did you expect to happen when running the steps above? -->
   The KVM host will be reset.

   ##### ACTUAL RESULTS
   <!-- What actually happened? -->
   The `kvmscript.sh` will reboot the server.
