Hi all,<br>
<br>
After succesful update from 3.6 to 3.8.1, we're testing the
premigrate/postmigrate feature. We're using a shared system
datastore, and all the VM have iscsi volumes attached. The
premigrate feature is really useful for this scenario, letting us to
login into the iscsi volumes before migration without need for a
more complex setup involving qemu scripts at the hosts.<br>
<br>
We're using a modified version of the iscsi DATASTORE / TM drivers,
adapted to our Equallogic setup. These drivers are added to the
opennebula config as new driver (eqliscsi), and all the other
features run as expected.<br>
<br>
But there's some questions about the premigrate/postmigrate feature:<br>
<br>
- There's premigrate/postmigrate scripts at every TM driver, but the
only one called when doing a VM migration was the shared TM.<br>
- The eqliscsi TM premigrate scripts must be called from the shared
TM?<br>
- It's planed to call every premigrate script from every datastore
used inside the VM?<br>
<br>
I'm thinking in a scenario where one VM has different disks from
different datastores attached and need to do some operations
before/after migration. The premigrate/postmigrate scripts must be
called at least for every different TM driver needed.<br>
<br>
Maybe I'm mixing some concepts between datastore and tm drivers, but
some help to define the correct way to manage this scenario wil be
grealty appreciated.<br>
<br>
Best regards,
