[ovirt-users] [Python SDK] Setup Host network with IP address

[TranceWorldLogic .]

Hi,

I am trying to setup network via python sdk as shown below:

myhost_service.setup_networks( modified_network_attachments = [
types.NetworkAttachment(
host = myhost,
host_nic =
types.HostNic(name="eth0"),
network =
types.Network(name="Hello"),
ip_address_assignments = [
types.IpAddressAssignment(
assignment_method =
types.BootProtocol.STATIC,
ip = types.Ip(

address="192.168.300.10",
netmask="255.255.255.0",

version=types.IpVersion.V4,
),
)
],
),
   ] )


But I am getting below error:
"ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Bad
format of IPv4 address]". HTTP response code is 400."

Please help me.
Ovirt release version = 4.0

Thanks,
~Rohit

[ovirt-users] ovirt Node Building

[shubham dubey]

Hello,
I have recently build ovirt-engine from source using this link(
http://www.ovirt.org/develop/developer-guide/engine/engine-development-environment/).
Now I want to build ovirt node using this(
http://www.ovirt.org/develop/projects/node/building/). I am confused that
can I build that node on the same system as of ovirt-engine or I need to do
these steps on any other system.

Thanks,

[ovirt-users] Setting up hosted engine appliance on a bonded interface

[Bryan Sockel]

Hi,

I am attempting to deploy an appliance to a bonded interface, and i getting 
this error when it attempts to setup the bridge:

Is it possible to deploy an appliance to a network bond?  My Network guy has

[ovirt-users] Answer file key for "nonlocal postgres"

[Jamie Lawrence]

Hello,

I’m working on an answerfile for an unattended Ovirt install. The engine and 
the data warehouse DBs live remotely. I think I have most of the relevant keys 
defined, but appear to be missing one, because the installer is attempting to 
manage a local Postgres.  Log and error below. Keys I’ve defined so far are:

OVESETUP_DB/secured=bool:False
OVESETUP_DB/user=str:engine
OVESETUP_DB/password=str:[SNIP]
OVESETUP_DB/dumper=str:pg_custom
OVESETUP_DB/database=str:ovirt_engine
OVESETUP_DB/fixDbViolations=none:None
OVESETUP_DB/host=str:[SNIP]
OVESETUP_DB/port=int:5435
OVESETUP_DB/filter=none:None
OVESETUP_DB/restoreJobs=int:2
OVESETUP_DB/securedHostValidation=bool:False

And a similar set for the DWH.

Anyone know what I am missing?


Thanks in advance,

The user error is:

From the installer log, it obviously still thinks it is supposed to set up PG

Which version of vdsm (and vdsm-hook-fcoe) are you using?

[ovirt-users] strange behavior of ovirt-node ng update

[Sergey Kulikov]

I have one Ovirt Node in my test cluster(others are centos), I'm observing 
strange behavior of update
checker in engine.
In options I can see:
engine=# select * from vdc_options where 
option_name='OvirtNodePackageNamesForCheckUpdate'; 
 option_id | option_name |option_value| 
version 
---+-++-
   124 | OvirtNodePackageNamesForCheckUpdate | ovirt-node-ng-image-update | 
general
(1 row)

so it tries to check for updated version of ovirt-node-ng-image-update, but 
there is no ovirt-node-ng-image-update package installed inside updated node 
image, so engine always shows
available updates on this node to the same version:
> Check for available updates on host XXX was completed successfully with 
> message 'found updates for packages ovirt-node-ng-image-4.1.1-1.el7.centos, 
> ovirt-node-ng-image-update-4.1.1-1.el7.centos'. 
I saw a bug in bugzilla, that it should be fixed in 4.0
Initially engine was set up as 4.x version, after that updated between releases 
and finally to 4.1.0,
and today to 4.1.1.
I saw this behavior on 4.1.0 node and also on 4.1.1, on this page:
http://www.ovirt.org/node/4.0/update/
Maybe my OvirtNodePackageNamesForCheckUpdate was changed between releases, but 
engine-setup left it untouched
and i should change it manually? If so, what it should look like?

[ovirt-users] Upgrade from 3.6 to 4.1

[Brett Holcomb]

I am currently running oVirt 3.6 on a physical server using hosted 
engine environment.  I have one server since it's a lab setup.  The 
storage is on a Synology 3615xs iSCSI LUN so that's where the vms are.  
I plan to upgrade to 4.1 and need to check to make sure I understand the 
procedure.  I've read the oVirt 4.1 Release Notes and they leave some 
questions.


First they say I can simply install the 4.1 release repo update all the 
ovirt-*-setup* and then run engine-setup.


1. I assume this is on the engine VM running on the host physical box.

2.  What does engine-setup do.  Does it know what I have and simply 
update or do I have to go through setup again.


3.  Then do I go to the host and update all the ovirt stuff?

However, they then say for oVirt Hosted Engine follow a link for 
upgrading which takes me to a Not Found :( page but did have a link back 
to the release notes which link to the Not Found which  So what do I 
need to know about upgrading a hosted engine setup that there are no 
directions for.  Are there some gotchas?  I thought that the release 
notes said I just had to upgrade the engine and then the host.


Given that my VMs are on iSCSI what happens if things go bad and I have 
to start from scratch.  Can I import the VMs created under 3.6 into 4.1 
or do I have to do something else like copy them somewhere for backup.


Any other hints and tips are appreciated.

Thanks.

The ovirt-shell tools is deprecated since version 4.0 of oVirt, and will
be removed in version 4.2. I suggest that you avoid using it, and
consider using the Ansible modules:

  http://docs.ansible.com/ansible/list_of_cloud_modules.html#ovirt

Or one of the SDKs:

  Python: https://github.com/oVirt/ovirt-engine-sdk
  Ruby: https://github.com/oVirt/ovirt-engine-sdk-ruby
  Java: https://github.com/oVirt/ovirt-engine-sdk-java

In particular these SDK examples may be of interest:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/add_vm_snapshot.py


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/clone_vm_from_snapshot.py

If you still want to use ovirt-shell, then it should be something like this:

  add snapshot --parent-vm-name myvm --description mysnap

That will return the snapshot data, including the id, take note of it,
and then:

  add vm --name mynewvm --snapshots-snapshot
"snapshot.id=the_id_of_the_snapshot" --cluster-name mycluster

NFS ISO domain on the engine machine is generally deprecated, and

Re: [ovirt-users] OVS switch type for hosted-engine

[Devin A. Bougie]

Just to close this thread, we were able to manually convert our hosted-engine 
4.1.1 cluster from the Legacy to OVS switch types.  Very roughly:
- Install first host and VM using "hosted-engine --deploy"
- In the Engine UI, change Cluster switch type from Legacy to OVS
- Shutdown the engine VM and stop vdsmd on the host.
- Manually change the switch type to ovs in 
/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt
- Restart the host

After that, everything seems to be working and new hosts are correctly setup 
with the OVS switch type.

Thanks,
Devin

Sure enough, once we added the data storage the hosted-storage imported and 
attached successfully.  Both our hosted-storage and our VM data storage are 
from the same iSCSI target(s), but separate LUNs.

Many thanks!

Hi Juan,

I confirm this was working with 4.0.6 (but the same SDK package).
The script is relatively new but I'm 100% sure it has been in

after 5-6 iterations the exception starts showing up.

I've voted for the bug and added myself as CC.

Thank you.

Hi,

We've recently upgraded from oVirt 4.0.x to 4.1.0 and it seems that
the
behavior of a script we wrote in Python-SDK has changed slightly.
We
have a script that needs to be executed forever (daemon mode). This
daemon creates an ovirtsdk4.Connection object and uses the same
Connection object all the time.

conn = sdk.Connection(
  url=URI,
  username=USERNAME,
  password=PASSWORD,
  ca_file=CAFILE
)

Between iterations we have ~5 minutes delays which we accomplish
with a
time.sleep(...) call.

After some of these iterations (5 or 6), when trying to perform an
operation on the Connection object (in this case, listing all SDs):

    try:
        sys_serv = conn.system_service()
        sd_serv = sys_serv.storage_domains_service()
        storages = sd_serv.list(search=sd_search_query)
    except Error, e:
        log('ERR: Error getting storage domains: %s' % (e))

We start getting exceptions (i.e., the sd_serv.list() call throwing
an
Error exception) with this message:

    ERR: Error getting storage domains: HTTP response code is
401.

I believe this has something to do with the Connection object
expiring
(even if it's not idle more than 5 minutes at any time). Is there a
way
to "refresh" the Connection object so it doesn't auto-logout
(assuming
this is the actual problem)?

As I said, this started happening as of oVirt 4.1.0.
ovirt-engine-sdk-python version is 4.1.1.

Any ideas?

This sound like this bug, opened yesterday:

  SSO token used for the API expires when running only queries
  https://bugzilla.redhat.com/1434605 [1] [1]

But I thought the same happened in 4.0. Can you confirm that you
don't
see this problem in 4.0?

Open possible workaround is to force a refresh of the backend
session
sending an external event, like in this example:



https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py#L112-L131

[2]
[2]

I also think that we need to modify the SDKs so that they detect
expired
SSO tokens and renew them automatically. I will open another bug
for that.

 Here is the bug for adding automatic SSO token renew to the SDK,
in
case
 you want to follow/vote it:

Re: [ovirt-users] ACTION_TYPE_FAILED_NO_SERVERS_FOR_CLUSTER

[Davide Ferrari]

Sorry for the delay, I've managed to fix it. It was all due to a permission
error in the gluster volume which I created via CLI manually, I forgot to
set the vdsm unix user UID and GID permissions to it. After doing that, I
could import the new gluster volume as a data domain in the new cluster and
then enable Gluster management in the cluster and now everything works as
expected!

[ovirt-users] How to attach Host device to VM ?

Hi,

I have created an LVM device( /dev/myvg/lvm1 ) in Host.
I want that device to attach with VM.

Can I attach device to VM via vdsClient ?
If yes, please provide me example command that I need to run.

Each cluster is also created as a gluster trusted storage pool - that is
nodes in the cluster are peer probed to each other. A gluster volume can
only span one trusted storage pool at a time.

[ovirt-users] ovirt 4.1 - mount recovery iso for failing vm ?

[Ian Neilsen]

Guys

I've spent the day reading any and all content on recovering a failing to
boot vm under ovirt 4.1 and am finding many cmds are deprecated , old
processes no longer work.

What is the correct way to mount an iso to perform recovery on a boot
partition of a failing VM in oVirt 4.1?

vm.conf, virsh, virt-edit, vmhost.xml, vdsClient, new vda, way too many
options and no singular right way to do this that works well.

Re: [ovirt-users] how to handle mount options for hosted engine on glusterfs

I Think I am going to have to go the "virsh" path and mount a guest based
cdrom storage device using a live cd and fix the vm disk this way.
Meanwhile fix up the fact that vnc and serial console have both been wiped
out following the 4.1 upgrade.

The priority is a value between 0 and 100, and the mapping to the text
displayed in the GUI is the following:

  0..25 -> LOW
  26..74 -> MID
  75..100 -> HIGH

In the reverse direction:

  LOW -> 1
  MID -> 50
  HIGH -> 100

So if you want to set it to HIGH use 'priority = 100'.

You can get a clue as to what *might* be included by searching bugzilla.
E.g. to find all bugs with target milestone currently containing ovirt-4.2:

https://bugzilla.redhat.com/buglist.cgi?classification=oVirt=target_milestone=bug_status_id=7207043=substring=notequals_format=advanced=ovirt-4.2=CLOSED

Obviously, at this point not everything is there, and some things that
are there might be postponed or closed eventually.

[ovirt-users] How to set priority for HA VM via Python SDK ?

[TranceWorldLogic .]

Hi,

I want to set priority of Highly Available VM as High via python SDK.
I provided information as shown below:

vm = self.vms_service.add(
  vm = types.Vm (
high_availability = types.HighAvailability(
enabled = True,
priority = 1,
),
),
)

As see above priority we have to provide as number but in GUI we can choose
drop down menu as ("LOW", "MID" and "HIGH").
I wan to set priority as "HIGH", which integer value I have to set in
priority ?
I tried with 1 and 3 it shows "LOW" in both cases.

Please help me.

Thanks,
~Rohit

Re: [ovirt-users] Python-SDK: ovirtsdk4.Connection object autologout?

[nicolas]

Hi Ravi,

Could you please tell me what's the right way to apply this patch on an 
already working oVirt instance? I already have applied some patches on 
*.py files, but it seems the *.java files are not there.


Thanks!

Hi Nicolás,

There has been some changes to how a session is refreshed after 4.0.
So this is a BZ and is being tracked by BZ 1434605.

Will post a patch to fix this. Thanks for reporting the issue.

Hi Juan,

I confirm this was working with 4.0.6 (but the same SDK package).
The script is relatively new but I'm 100% sure it has been in
execution for several weeks, in contrast to current version where
after 5-6 iterations the exception starts showing up.

I've voted for the bug and added myself as CC.

Thank you.

Regards,

Nicolás

Hi,

We've recently upgraded from oVirt 4.0.x to 4.1.0 and it seems that
the
behavior of a script we wrote in Python-SDK has changed slightly.
We
have a script that needs to be executed forever (daemon mode). This
daemon creates an ovirtsdk4.Connection object and uses the same
Connection object all the time.

conn = sdk.Connection(
  url=URI,
  username=USERNAME,
  password=PASSWORD,
  ca_file=CAFILE
)

Between iterations we have ~5 minutes delays which we accomplish
with a
time.sleep(...) call.

After some of these iterations (5 or 6), when trying to perform an
operation on the Connection object (in this case, listing all SDs):

    try:
        sys_serv = conn.system_service()
        sd_serv = sys_serv.storage_domains_service()
        storages = sd_serv.list(search=sd_search_query)
    except Error, e:
        log('ERR: Error getting storage domains: %s' % (e))

We start getting exceptions (i.e., the sd_serv.list() call throwing
an
Error exception) with this message:

    ERR: Error getting storage domains: HTTP response code is
401.

I believe this has something to do with the Connection object
expiring
(even if it's not idle more than 5 minutes at any time). Is there a
way
to "refresh" the Connection object so it doesn't auto-logout
(assuming
this is the actual problem)?

As I said, this started happening as of oVirt 4.1.0.
ovirt-engine-sdk-python version is 4.1.1.

Any ideas?

This sound like this bug, opened yesterday:

  SSO token used for the API expires when running only queries
  https://bugzilla.redhat.com/1434605 [1]

But I thought the same happened in 4.0. Can you confirm that you
don't
see this problem in 4.0?

Open possible workaround is to force a refresh of the backend
session
sending an external event, like in this example:



https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py#L112-L131

[2]

I also think that we need to modify the SDKs so that they detect
expired
SSO tokens and renew them automatically. I will open another bug
for that.


 Here is the bug for adding automatic SSO token renew to the SDK, in
case
 you want to follow/vote it:
