The table in the VM listing page get its dimension on load time and will not follow browser resizing despite ample space being available. A refresh will redraw the table along the new browser window size resolving the problem but still...

Dear devs,

Testing v1.6.0 with localization to Russian.
Changing settings.py
LANGUAGE_CODE = 'ru-Ru'
returns an AttributeError: 'NoneType' object has no attribute '_info'

The issue #51 seems to related to this one.

I found one solution which is specific to Django Version 1.4.5:
https://code.djangoproject.com/ticket/18192
where one has to fix the file
ganetimgr/lib/python2.7/site-packages/django/utils/translation/trans_real.py
like this:

def _translation(path):
            try:
                t = gettext_module.translation('django', path, [loc], DjangoTranslation)
                t.set_language(lang)
                return t
            except IOError:
                return None

        res = _translation(globalpath)

        ### salsa: THIS CODE I have to add before running syncdb
        if res is None:
            return gettext_module.NullTranslations()

        # We want to ensure that, for example,  "en-gb" and "en-us" don't share
        # the same translation object (thus, merging en-us with a local update
        # doesn't affect en-gb), even though they will both use the core "en"
        # translation. So we have to subvert Python's internal gettext caching.
        base_lang = lambda x: x.split('-', 1)[0]
        if base_lang(lang) in [base_lang(trans) for trans in _translations]:
            res._info = res._info.copy()   ### salsa: HERE it throws AttributeError 
            res._catalog = res._catalog.copy()

following the instruction in the manual will result in an uncompleat database

Hi,
In the details page of an instance, could you please add a field displaying the disk-template type (plain, drbd...) of an instance ?
Right now, it seems that there's no way to get that information within ganetimgr

Thanks !

ganetimgr supports two console types: java and novnc. Once novnc is setup the web interface has two buttons: Console (WebSock) and Console (Java)

The Java console button can't be disabled, so I tried to set it up, but I can't find instructions on this.

It initially fails with "No such file or directory":

/srv/www/ganetimgr/util/vapclient.py in request_forwarding
    ctrl.connect(CTRL_SOCKET) ...
▶ Local vars
/usr/lib/pymodules/python2.7/gevent/socket.py in connect
                    raise error(result, strerror(result)) 

But if I start a twisted vncap on that unix socket using

twistd --pidfile=/tmp/proxy.pid -n vncap -c unix:/var/run/vncauthproxy/vncproxy.sock

then it just hangs waiting for a response from http://<host>/cluster/<cluster>/<instance>/vnc

I notice the request format in request_forwarding() uses a different format than request_novnc_forwarding():

    req = {
        "source_port": int(sport),
        "destination_address": daddr,
        "destination_port": int(dport),
        "password": password
    }

vs.

        request = {
            "daddr": daddr,
            "dport": dport,
            "password": password,
            "ws": True,
            "tls": tls,
        }

So does it require a different VNC proxy, and if so, what is it?

settings.py.dist contains examples like this:

OPERATING_SYSTEMS = {
    "debian-wheezy": {
        "description": "Debian Wheezy 64 bit",
        "provider": "image+default",
        "osparams": {
            "img_id": "debian-wheezy",
            "img_format": "tarball",
        },
        "ssh_key_param": "img_ssh_key_url",
    },

The use of "image+default" suggests that these are for ganeti-instance-image. However the img_id and img_format parameters belong to snf-image.

It would be clearer if the examples were changed to:

        "provider": "snf-image+default",

Missing in the install documentation:

• edit /etc/default/beanstalkd

  ## Uncomment to enable startup during boot.
  START=yes
  

• service beanstalkd start

Hi!

I've been trying your Stable/Master/Dev versions of ganetimgr for snf-image OS provider and always get the same error on application/$id/review page just under the "Operating System" with text in red saying
"Δεν βρέθηκε το λειτουργικό που ζητηθηκε: debian_base-7.0-x86_64"
when submiting the Application I get (in v1.5.5 of ganetimgr) the TypeError in "/srv/www/ganetimgr/apply/models.py in submit, line 196" of "
'NoneType' object has no attribute 'getitem'".
This is coded in

It is ok when I use just "img_id": "debian-base" for ex. in settings.py for snf-image+default provider.

Could you please have a look at it?
I would appreciate solving this issue as soon as possible because it stops me from going further in deploying a testbed Ganeti cluster.

Thanks! Serge

Hi,

after a while I figured out that for Django 1.7 the locale folder needs to be moved into the ganeti/ subfolder (mv locale ganeti/) to work again.

See https://docs.djangoproject.com/en/dev/topics/i18n/translation/#how-django-discovers-translations

A user with the "ganeti | cluster | Can view all instances " permission can query the status of all the instances from all the clusters from the main page but gets (Access denied) when trying to access a instance page (e.g. /cluster///).

The following error occurs when a username contains the @ character:
NoReverseMatch: Reverse for 'user-info' with arguments '(u'user', u'[email protected]')' and keyword arguments '{}' not found.

Hi, devs!

Code in util/vapclient.py of the master branch says we must use the snf-vncauthproxy of the version prior to 1.5 when Unix domain control sockets were replaced with TCP control sockets:
CTRL_SOCKET = "/var/run/vncauthproxy/vncproxy.sock"

Right now I'm deploying GanetiMGR (master branch) with https://github.com/grnet/snf-vncauthproxy (master, v1.6). And I'm working towards rewriting some code to support that.

Is there any specific reason for using Unix domain control socket?

I can't find any documentation of what COLLECTD_URL is supposed to point to. I poked around at some of the collectd frontends I could find and none seem to have a matching URL format to what ganetimgr generates.

From /var/log/ganeti/watcher.log

I am guessing an exception has occurred because it doesn't say "Mailing managers about ...", but if so the exception has been silently caught, and I can't see in the code where this happens. I think it should be caught and logged

Note: this particular error was caused by no MTA being installed on the host where ganetimgr was running, and installing an MTA fixed the issue, but there were no clues in the log.

These are very minor niggles, but:

• "clear cache" adds a '#' to the end of the URL in the browser URL bar (should be possible for javascript to suppress this?)
• "clear cache" is not available on a mobile device

For admin accounts, one should be able to 'Select Clusters' in Audit Log as is the case with 'Jobs'

If you approve a new instance application, but the instance creation fails, then:

• the web interface returns a 500 error (*)
• the application moves into the "completed applications" section (although its status is still "submitted")
• if you click on the application you can see its parameters, but not edit them
• if you click on the hostname within the application, you get a 404 error (presumably because ganetimgr thinks the instance exists, but it doesn't)

To reproduce: any type of event which causes instance creation to fail will do, e.g. not having enough RAM on the cluster. However an easy-to-reproduce case is where the os-type does not exist, e.g. if you select the "noop" os type but this is not installed.

Desired behaviour: ideally leave the application queued and report the error somewhere (e.g. in the "comments to the user" box), and allow the parameters to be edited and resubmitted. Or else treat it as a rejection, and append the error in the "comments to the user"

A new cluster(s) info page could be useful for admins. It could provide details such as:

• Total number of VMs
• Number of Running/Shutdown VMs
• Networks per cluster + some info about them, eg Free IPs per network
• Number of nodes + node roles in the cluster
• Used/Free resources per cluster (Disk/RAM)

Hi,
It looks like it isn't possible right now to change the vcpu/memory/network ressource allocated to an instance after it has been created in the "configuration options" section

Would it be possible to add that functionnality please ?
Thanks

Until now a VM creation get's routed to a specific cluster by choosing a network that is attached to a cluster. It would be nice to be able to have cross-cluster networks (common with bridged networks), and to be a able to both select a cluster name/slug and a network upon creation.

This probably needs a major redesign but it's probably worth it since such cases already exist.

The lower memory limit for a VM is defined in two different places, which makes it awkward if you want to allow a smaller instance. This patch avoids the duplication, so you only have to set VALID_MEMORY_VALUES.

It seems that ganetimgr don't support new versions of Django.
A quick test on Debian Jessie gives me the following error while initializing the database:

Actions on VMs through button is really nice and cool but a user may inadvertently press one rebooting or shutting down a VM causing DoS to his own services. A dialog requesting confirmation would go a long way to avoid that

Instance rename requires that the instance is turned off. When an instance is shutdown via console or terminal, then ganeti will start it automatically. For rename to work properly, the instance need to be shutdown via ganetimgr web interface.

• Add a note for this in the disclaimer dialog box
• Perform an instance oper status check prior to showing the final rename action button

at /user/info/user/USERNAME there is a table showing the VMs of the user. It would be nice to have the disks column, as it appears in the home page.

or maybe have a common/reusable view/table for both pages ?

I just figured out what caused my Ganeti Mgr instance to crash on listing VMs under the Nodes submenu and the when clicking on Graphs -> Get Graphs .

The ganetimgr WebGUI does not like if the "cluster_slug" parameter of a Ganeti cluster contains the dash character ("-"). If a cluster_slug contains a slash, the UI (i.e., django) spits out this error message:

Dear devs,
How do you enable SAML authentication for GanetiMGR?

RAPI now allows passing osparams to the reinstall call. So we can present the user with the option to Reinstall an instance with a different OS

If you create a VM with the default selection of "5GB", you get a disk which is 5242880000 bytes = 5_1000_1024*1024 bytes, so is neither 5GB nor 5GiB.

It looks like this comes from apply/models.py:

                                           disks=[{"size": self.disk_size * 1000}],

Suggest changing this to * 1024

Sometimes both users and admins need to look back at previous actions they've done. It would be nice to keep a record of every user's action so that users of ganetimgr could see their past actions and admins could see a page with a listing of every users' action.

ganetimgr should keep a record of when a user has started/stopped/reinstalled/deleted/etc a VM, when a user has added a co-admin, when an admin locked/isolated a VM and so on.

At the admin "job listing" page we need to have filters though so we can filter by action type, by user, by cluster, by node or by VM name, etc.

It would be really helpful to have English translations of the notification E-mails:

# find /srv/www/ganetimgr/templates -name '*.txt'
/srv/www/ganetimgr/templates/pass_change_notify_mail.txt
/srv/www/ganetimgr/templates/reinstall_mail.txt
/srv/www/ganetimgr/templates/instance_created_mail.txt
/srv/www/ganetimgr/templates/application_rejected_mail.txt
/srv/www/ganetimgr/templates/registration/activation_complete.txt
/srv/www/ganetimgr/templates/registration/activation_complete_subject.txt
/srv/www/ganetimgr/templates/registration/activation_email.txt
/srv/www/ganetimgr/templates/registration/activation_email_subject.txt
/srv/www/ganetimgr/templates/apply_mail.txt
/srv/www/ganetimgr/templates/idle_account.txt

Whilst this could be done fairly easily with the help of Google Translate, there's currently no place to store multiple language versions of each E-mail.

One option might be to rename these to *.el.txt so that *.en.txt can sit alongside. However all the code which calls email = render_to_string("name_of_template.txt", ...) would need to be changed. Would the language have to become a per-user profile setting?

As a short-term fix, these mail bodies could have Greek with the English translation in-line below.

In a specific VM's page, the services line icons are being displayed to point out the services (like Mail Server?) available to this. While the icons are nice and quite explanatory, for completeness sake tooltips should be provided as well

The install instructions don't say you need to change NODATA_IMAGE for the graph to display correctly when insufficient data is present.

However a one-line patch makes this automatic.

The RSS icon on latest news creates the impression that users can use any RSS reader to subscribe to an RSS feed informing them about the service. A different icon would avoid that confusion

It would be nice if ganetimgr had an extra field in the instance boot-configuration, for specifying an sha1sum (which could be copy-pasted) to use to verify an ISO image when it's being booted from an http URL. If that's not always possible it could just be an optional field (skipping the check if empty). The local patches to ganeti-instance-image do this under the hood anyway, so it should be
trivially easy to implement in the UI, and would be much safer against MITM attacks.

Dear devs,

I'm testing v1.6.0 with localization to russian.

After changing language in the web interface to a localized one changing back to English doesn't work (nothing happens). The same actually happens with Greek.

The small icons displaying possible VM actions are quite nice but not always self explanatory. Tooltips could be added to provide a hit on what each button does

When using the web interface in my profile page with the browser window width less than 1540 px then some input fields might become chopped and not appear in their entirety onscreen. This problem stops when the browsers width is resized below 743 px and the three boxes align vertically instead of horizontally
Using google chrome on Debian wheezy, pixel numbers could vary depending on fonts used I assume

Add alphanumeric sorting in 'Nodegroups -> Nodes' for each node group
