On actual testing, I could see that kvmheartbeat.sh script fails on NFS server failure and stops the agent only. Any HA VMs could be launched in different hosts, and recovery of NFS server could lead to a state where a HA enabled VM runs on two hosts and can potentially cause disk corruptions. In most cases, VM disk corruption will be worse than VM downtime. I've kept the sleep interval between check/rounds but reduced it to 10s. The change in behaviour was introduced in #2722.
