Hi Yordan,

There’s an initiative now to combine all sources of documentation into one place (
Please have a browse and whenever you think you could edit/correct/add something there’s
a link ‘Edit on GitHub’ in the header, where you can make your changes.

Hello Giles and community,

Wondering where documentation contributions should be sent?
For example if a missing spot is found in the current docs or just want to write down a step-by-step
guide for certain customization.

Usually I document any integrations, customizations or deployments for my colleagues. I am
new to ACD and don’t mind creating some docs during the process of learning (and setting
up our production later, fingers crossed!).

Best regards,

" If so, why hasn’t anyone fixed the following document yet"

Because this is an open source community of volunteers (who would probably appreciate you
wording such points in a more constructive way)

Of course, your could always volunteer to do it yourself

Kind regards

Gosh,  I just encountered exactly the same problem!

If I understand this thread correctly, the root cause is that the document contains wrong
url for systemvm template to download, it points to 4.11.0 version instead of 4.11.1 version
of templates for all hypervisors!

If so, why hasn’t anyone fixed the following document yet:

   Before upgrading the router, can I restart the network and check "Make redundant" so that
VMs don’t becoming inaccessible during upgrade?  Will this work without upgrading first?

You can either Restart the network with cleanup or simply destroy VR and let it be created
on the next VM deployment.

  Thanks, nearly back up and running.  One question, what about the Virtual Router upgrade?
 What do I do if the upgrade fails on the Virtual Router?  Looking for docs on this, but can’t
find anything.

  Thanks for your assistance.

Yes. this should bring you back.
However if you perform what you described in your previous reply + rename template in CS DB
to systemvm-kvm-4.11.1  from what it is now systemvm-kvm-4.11 you should be able to bring
all up as it is. Updating template image is not enough.

 OK thanks a lot, Sergey,

 That helps.  What’s the best method to roll back?  Just use yum to roll back to 4.9 and
rebuild the DB from backup?

The fastest and easiest way is to rollback both DB and management server and start over. You
need to have correct systemVM template registered before you initiate an upgrade.

Is there anybody out there that can assist with this?

Is there any more specific instruction about this?

What is the best practice?  Should I roll back first?  Is there any documentation about rolling
back?  Do I uninstall cloudstack management and re-install 4.9?

Or is it as simple as just overwriting the file?  If so, what about the
file and the metadata in there like qcow2.size?

yes - please try the proper 4.11 systemvm templates.

Can I manually download the systemvm template from here?

Then manually overwrite it in the filesystem and update it accordingly in the database?

I just tried to upgrade from 4.9 to 4.11, but it looks like the system VM template I downloaded
