Mon Feb 15 11:00:18 UTC 2016

Hi,

You hit the target !!!

I enable overcommitting on the destination , then  I’m able to migrate towards it.

Now I’ve to clarify my  Guests  memory requirements.

Thx for your help.

Regards,

J.P.

Hi,

Within the ovirt GUI , I got this :

Max free Memory for scheduling new VMs : 0 Mb

It seems to be the root cause of my issue .

Vmstat -s ran on the destination host returns :

[root at ldc01omv01 vdsm]# vmstat -s

Is it vdsm that returns this info to ovirt ?

I tried a migration this morning at 10/04.

I attached  vdsm destination log .

 << Fichier: vdsm.log >>

Is it worth to increase of level of destination log ?

Thx for help.

Regards,

J.P.

Hi Jean-Pierre,

Seems by the log you've sent that the destination host, ldc01omv01, is filtered out, cause of lake of memory.
Is there enough memory on the destination, to run this VM?

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.

Thanks,
Ilanit.

Hi,

When trying to migrate a Guest between two nodes of a cluster (from node1 to ldc01omv01) , I got this error ( in ovirt/engine.log file) :

In ovirt GUI nothing strange .

How may I go further to investigate this issue ?

Thx for help.
