Hum, that's not very clear in the doc.<br>
I though that DS 0 was local to all ALL hypervisors ...<br>
<br>
Thank you<br>

<br>
I am using OpenNebula 4.2 with a shared (qcow2) storage +
kvm.<br>
I am trying to livre migrate a vm from hostA to hostB.<br>
It fails with the following message:<br>

<br>
As I understand, using a shared datastore, One create a
symlink to the real shared DS into the DS 0 (for system
images).<br>
But, It seems that on target hostB, the symlink is not
created before migration....<br>
Am I missing something ?<br>
<br>
Thank you<br>
<br>
Best regards,<br>
Nicolas.<br>
