As you mention, we have implemented a static vlan configuration for
the moment.<br>
<br>
We are glad to know that these issues could be addressed in
Opennebula v3.2. <br>
<br>
Please, consider our help for testing whatever you may need.<br>
<br>
Thank you very much for your help and such a great product,<br>
Best Regards,<br>

<div><br>
</div>
<div>you make very valid points and we're aware of those
limitations. They have actually been reflected on the
documentation:</div>

<div><br>
The problem is that the network management is based on the
hook subsystem, but we have realized there should be a
specific driver for networking. We have created a feature
ticket to develop this functionality:</div>
<div><a moz-do-not-send="true"
href="http://dev.opennebula.org/issues/863"
target="_blank">http://dev.opennebula.org/issues/863</a></div>
<div>The target release for this functionality is OpenNebula
3.2.</div>
<div><br>
</div>
<div>For the moment, in OpenNebula 3.0, the only solution to
the aforementioned problems is to create a static network
configuration.</div>
<div><br>
</div>
<div>Regards,</div>

<br>
In previous version there was a cluster feature
that was replaced in OpenNebula 3.0 by ozones.<br>
Shouldn't opennebula make sure that all the nodes
in a zone are able to run a vm and thus handle
network creation on all nodes before starting a
new VM?<br>

<div bgcolor="#ffffff" text="#000000"> <font
face="Arial">Hello,<br>
<br>
We are testing hosted VLAN support in
OpenNebula to implement network
isolation. This feature seems to work
correctly when a new instance is
deployed, as it is stated in
oned.conf, hm-vlan hook is executed in
PROLOG state.<br>
<br>
However, there are another states
where VLANs and bridges should be
created (or its existence checked)
before executing a concrete operation:<br>
<br>
* Migration/Live migration of an
instance to a hypervisor where VLAN
and bridge of the instance has never
been created<br>
VLAN and bridge existence should be
checked and created if necessary
before migration is executed.
Opennebula 3.0 RC1 performs migration
without doing these checks and fails
to migrate/live migrate the instance,
leaving it in a FAILED state.<br>
<br>
* A failed instance cannot be
redeployed to a hypervisor where </font><font
face="Arial">VLAN and bridge of the
instance has never been created</font><br>
<font face="Arial">VLAN and bridge
existence should be checked and
created if necessary to redeploy the
image to the selected hypervisor.</font><br>
<br>
* A stopped instance <font face="Arial">cannot
be resumed if </font><font
face="Arial">VLAN and bridge of the
instance does not exist</font>.<br>
If we stop all instances of a concrete
hypervisor and reboot the hypervisor for
maintenance purposes, all bridges and
VLANs will be deleted. Stopped instances
won't resume because VLANs and bridges
requirements are not satisfied and will
enter in a FAILED state (performing a
deletion of non persistent disks; BTW,
we have removed deletion lines in
tm_delete script for the moment, :D). <br>
<br>
So, <font face="Arial">VLAN and bridge
existence should be checked and
created if necessary to
resume/migrate/livemigrate/recover_from_failed_state
the instance to the selected
hypervisor.</font> As it is stated in
oned.conf, hm-vlan hook could be
executed on:<br>
<br>
# Virtual Machine Hooks (VM_HOOK)
defined by:<br>
# name : for the hook, useful to
track the hook (OPTIONAL)<br>
# on : when the hook should be
executed,<br>
# - CREATE, when the VM is
created (onevm create)<br>
# - PROLOG, when the VM is
in the prolog state<br>
# - RUNNING, after the VM
is successfully booted<br>
# - SHUTDOWN, after the VM
is shutdown<br>
# - STOP, after the VM is
stopped (including VM image transfers)<br>
# - DONE, after the VM is
deleted or shutdown<br>
# - FAILED, when the VM
enters the failed state<br>
<br>
But I'm not able to find a procedure to
implement these functionalities in
oned.conf for the states I mentioned.<br>
<br>
Please, can you give me any clues?<br>
<br>
