<br>
I shared DS 0 using HA NAS.<br>
I got now:<br>

<br>
This is logical, because disk.1.iso was created on hostA, then,
retrying to restart VM 77 to hostB encounters an error, because file
already exists ...<br>
<br>
The log was generated because I activated the hook to restart VMs on
other HV ...<br>
<br>
Then, my VMs was deleted ...<br>
<br>

I am using OpenNebula 4.2 with a shared

<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>
