<div>Hi,t<br></div><div><br></div><div>I knew my issue sounds weird, and I'm not sure it is opennebula's fault. But the problem is really annoying, so can anyone shed some light?</div><div><br></div><div>I've a opennebula cluster deployed and running, with local disk. When a new VM gets provisioned, the disk template is copied from a NFS to the host's local disk. I've two VMs running on two hosts. These VMs have some heartbeat connection between them, for HA. However when a third VM is provision on one host (during the disk image copy process), the heartbeat connection is timeout (socket returns "Broken Pipe"). So the failover is triggered....(obviously it is NOT correct).</div>
<div><br></div><div>CPU usage during the copying, and it was around 17%, which is not high. Ping the host didn't show significant lag. I don't really understand why the host's disk I/O triggers the VM's network problem, do you?</div>
