<div dir="ltr">Hi Carlos<div><br></div><div>After digging the problem further, my state change problems started happening after I switched my VM monitoring from the VMM POLL to the new IM MONITOR VM polling available in 4.0.</div>
<div><br></div><div>It seems :</div><div><br></div><div>- VM enters RUNNING state (from PROLOG)</div><div>- OpenNebula triggers a VMM POLL action - But I have the VMM POLL action completely wiped out from my driver and replaced by the IM MONITOR polling. Monitoring fails (actually my VMM driver ignores the POLL action)</div>
<div>- VM enters UNKNOWN state (from RUNNING)</div><div>- Normal IM MONITOR polling occurs, the new VM is detected and returned with the host monitoring</div><div>- VM enters RUNNING state (from UNKNOWN)</div>
<div><br></div><div>In that case, implementing the "FROM" VM_HOOK option will not help (I was trying to detect that initial "UNKNOWN/RUNNING" state flap when my VMs are initially deployed).</div>
<div><br></div><div>Perhaps we should look at delaying the first VMM POLL action until the next time the host the VM is running is monitored?</div><div><br></div><div>Of course, another option for my would be restoring my VMM POLL action and not dropping it out entirely even if it has been replaced by IM MONITOR....</div>
