[one-users] Live migrate error, disk.0 does not exists at destination

[Nicolas Bélan]

Hello the list,

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

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

Thank you

Best regards,
Nicolas.
