<div>Hi,</div>
<div> </div>
<div>Within the ovirt GUI , I got this :</div>
<div> </div>
<div><i>Max free Memory for scheduling new VMs</i><i> : 0 Mb</i></div>
<div> </div>
<div>It seems to be the root cause of my issue .</div>
<div> </div>
<div>Vmstat -s ran on the destination host returns :</div>
<div> </div>
<div><i>[root@ldc01omv01 vdsm]# vmstat -s</i></div>

<div> </div>
<div> </div>
<div>Is it vdsm that returns this info to ovirt ?</div>
<div> </div>
<div>I tried a migration this morning at 10/04.</div>
<div> </div>
<div>I attached vdsm destination log .</div>
<div> </div>
<div> << Fichier: vdsm.log >> </div>
<div> </div>
<div>Is it worth to increase of level of destination log ?</div>
<div> </div>
<div> </div>
<div>Thx for help.</div>
<div> </div>
<div>Regards,</div>
<div> </div>

<div>Hi Jean-Pierre,</div>
<div> </div>
<div>Seems by the log you've sent that the destination host, ldc01omv01, is filtered out, cause of lake of memory.</div>
<div>Is there enough memory on the destination, to run this VM?</div>
<div> </div>
<div>Would you please send the source/destination hosts /var/log/vdsm/vdsm.log, /var/log/libvirt/qemu/VM_RHEL7-2, and /var/log/vdsm/libvirt.log, to provide more details.</div>
<div> </div>
<div>Thanks,</div>
<div>Ilanit.</div>
