This is a bug in the CLI:

  Invalid URL format when there are no dots in the host name
  https://bugzilla.redhat.com/1186365

The problem is that the CLI tries to verify the validity of the URL, and
it expects at least one dot in the host name:

  engine-tst.something

It was decided to not fix that bug because the CLI is deprecated since
version 4.0 of the engine, and will be removed in version 4.2.

As a workaround, try to use a fully qualified host name, which will most
probably include a dot anyhow. And you will need that fully qualified
host name anyhow, if you want to safely verify the certificate of the
server. See the bug for details. Alternatively you can use the IP
address directly.

As I said, the CLI is deprecated, so if you are starting from scratch,
I'd suggest you avoid it completely. Use one of the Ansible modules:

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

Or one of the SDKs:

  Python:
  https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk

  Ruby:
  https://github.com/oVirt/ovirt-engine-sdk-ruby/tree/master/sdk

  Java:

Re: [ovirt-users] VM switched off when migration for host maintenance fails

[Eduardo Mayoral]

Hi, Michal, thank you for your interest.

Is it reproducible? 

No. This is actually the first time that I have seen this behaviour, and a 
colleague of mine is developing a script for automatic patching of the hosts, 
so we are putting them into maintenance very frequently in the last few days.


It sounds similar to https://bugzilla.redhat.com/show_bug.cgi?id=1426727 but 
it’s not exactly that
Can you confirm you’re not using QoS/Quota? 

Yes, I can confirm we are not using QoS / Quota. Quota is disabled for the 
datacenter and there are no QoS policies defined.

Does the VM fail the same way when you migrate it manually?

No, I just did it several times and it migrated just fine.

If not, can you please reproduce with Move to Maintenance flow and narrow it 
down - timeframe, exact VM, corresponding engine and vdsm and qemu logs?

I will try to do this, but it will take some time, I will get back with the 
results next week.

Best regards!

Re: [ovirt-users] how to attach lvm device to VM ?

[Fred Rolland]

What you are trying to do is not supported in oVirt.
You cannot have local disks unless all the DC is configured with local
storage.

Like you mentioned, the engine and VDSM are not aware of this disk and
therefore no operation are supported (snapshot, copy, move...)

Re: [ovirt-users] Serious Trouble - Lost Domains

[JC Clark]

Thank you again for the response.

I have been able to import some of my orphaned storage domains, and the 
important one that contained all of the group policy desktop and 
document data for the entire school, has been safely recovered and back 
online.


I was getting an error because when I imported the domains, they were 
not mounting.  This was due to an improperly configured firewall.  I am 
still scavenging for some lost VM's today, it appears that some were not 
imported properly.


Thank you for your assistance.

My storage is NFS storage.

I made an attempt to import the domain and I got an error.  I will attempt to replicate tonight.


Do I have to alter any of the metafiles when importing?  I seemed to 
remember it didn't like to import another data center's domain.

I have backups of the old engine and 4 data domains an ISO domain and an

  I had to create a new host and SPM.  How do I get the floating domains

I have 1 storage container (85GB) I must get back.  MUST GET BACK!!

I really appreciate you reading my sob story.  Hope you can help..

[ovirt-users] ovirt-shell -- cannot even get started

[Phil Meyer]

This is either some very obscure syntax, or it may not be working.

Difficult to tell, since the error message seems to be generic:

...

   ERROR
=
"https://engine-tst/ovirt-engine/api"; is invalid url format, valid
format is http[s]://server:port/path, where path is usually
"ovirt-engine/api" or, for older versions of the engine, just "api".
 

...

That error is reported no matter where it is run from, and no matter what

combination of manual or automated interaction is used.


It should not be this hard.

42 different combinations were tried.


In one instance when using localhost as the hostname, it actually asked for

the certificate first, and then gave me the same error as above.


Lets just say that the command line was very familiar to me when Larry Wall

wrote the Configure script (that was before the GNU configure scripts).


A strait up actual example that works would be nice, or an explanation of

prerequisites, if there are any.  None are stated.


There is lots of mention of port numbers, but no actual port numbers
suggested.

Does not the ovirt-shell talk to the web server at port 443 if https is
specified?


The lsof command does not show any listeners that seem likely as a cli
interface:

And yes, the unfamiliar ones were tried. :)


The last straw was when a packet sniffer failed to capture ANY traffic
related to these

attempts.  Apparently the ovirt-shell command fails before even
attempting a connection.

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

[Devin A. Bougie]

Is it possible to setup a hosted engine using the OVS switch type instead of 
Legacy?  If it's not possible to start out as OVS, instructions for switching 
from Legacy to OVS after the fact would be greatly appreciated.

Many thanks,
Devin

That may have been the initial design of the feature, but it doesn't
currently work. That 'files' element isn't used at all. The recommended
way to create a file is using the custom script, as explained in this
example:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/start_vm_with_cloud_init.py#L48-L57

The use of 'types.CloudInit' is also disencouraged, use directly the
attributes of 'types.Initialization', as explained here:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/start_vm_with_cloud_init.py#L59-L86

Re: [ovirt-users] VM switched off when migration for host maintenance fails

[Michal Skrivanek]

Hi,
Is it reproducible?
It sounds similar to https://bugzilla.redhat.com/show_bug.cgi?id=1426727 but 
it’s not exactly that
Can you confirm you’re not using QoS/Quota?
Does the VM fail the same way when you migrate it manually?
If not, can you please reproduce with Move to Maintenance flow and narrow it 
down - timeframe, exact VM, corresponding engine and vdsm and qemu logs?

Thanks,
michal

Re: [ovirt-users] Error on Adding Host

[FERNANDO FREDIANI]

Final information about this.

I have re-installed the node with the ISO Release version (2017020112) 
and it now worked, both with SSH port 22 or changed. Therefore Node-NG 
ISO versions 2017030911 and 2017031104 don't work well with my Engine.


Despite it was still not able to fetch the fingerprint using running 
with a different port on SSH (and firewalld allowing the port) it was 
able to add the host normally and configure it correctly. Should I 
report it in bugzilla ?


Let me know if you need anything further about this.

Regards
Fernando

Hello Yedidyah and all

I bring you a slightly new information about this issue.

If I have the node SSH port changed to something else other than 22 it 
is unable to fetch the fingerprint. I changed it back to 22 and it 
worked to fetch the fingerprint but failed again when adding the host 
with the same error as before. (Yes I have allowed the port in the 
node firewall)


Before adding the host I have also cleaned both /root/.ssh/known_host 
and /var/lib/ovirt-engine/.ssh/known_hosts

Hi folks.

I think I have been hit by the most annoying error you can get on 
oVirt.

I have removed a Host from Engine, re-installed it with the latest
ovirt-node-ng ISO, tried to add the freshly installed Host back to 
Engine

and got the following error:

"Command returned failure code 1 during SSH session"

The host has the same FQDN as before and I have cleaned the SSH 
from the
known_hosts file in the Engine before trying to add it on the web 
interface.


I have also tried this process with 2 different ISO files:
- ovirt-node-ng-installer-ovirt-4.1-pre-2017030911 
.iso
- ovirt-node-ng-installer-ovirt-4.1-pre-2017031104 
.iso


And the Engine is version 4.1.1.4-1

Have searched for this error and there are a lot of people affected 
but not

a single solution solves it.

Please give some light.

Please check/share /var/log/ovirt-engine/engine.log on the engine
machine.

Best,

Yes you should use the remote viewer. The manager itself is not running the 
VMs, the hosts are running the VMs. So what happens when you click on the 
console button is that it generates a .vv file which your browser then 
downloads. If you associate remote-viewer with the .vv files it will attempt 
to connect to the *HOST* running the VM. Now its entirely possible your 
network topology doesn't allow you to connect to the host, while the manager 
(engine) is allowed to connect to the host.

If this is the case you need to configure a proxy on the engine that forwards 
to the host. Since we don't know your topology we can't say much more. But in 
general your browser connects to the engine which shows you the admin UI. Then 
when you want to connect with a console to a VM, your computer (remote-viewer) 
tries to connect to the host.

The message you are seeing is telling me you can't connect to the host.

Re: [ovirt-users] virt-manager not able to connect to my ovirt-instance

You should use remote-viewer to connect to the console of the VM, it's in the 
same package and you should pass the connection details to it from the 
portal(the console.vv file gets created including the otp).

Re: [ovirt-users] iSCSI and multipath deliberation

[Pavel Gashev]

Using this logic, oVirt should detect existing storages instead of 
attaching/mounting them. The same is for networks. A VM can be placed on any 
host that has required storage(s) and network(s) attached. Datacenters/clusters 
would be virtual things.

Pros:
* Flexibility for Linux admins, wider usage
* Less code. Less bugs.
Cons:
* You must be a Linux admin to maintain oVirt instances.
* It’s a step back in RHEV/oVirt functionality. I oVirt would lose users. 
RedHat would lose customers.

Subject: [ovirt-users] iSCSI and multipath deliberation

In my opionion the main problem in configuration iscsi and multipath is that 
the ovirt developers try to start everything automaticaly during installation, 
and then during start services like vdsmd.
But during installation process adminstrator shoud choose the right multipath 
WWID identifier only.
And administrator should be responsible for setting multipath and iSCSI 
properly.
Otherwise ovirt installator does everything automaticaly in the universal way 
which is weak due to so many storage types.

Hi again folks

I have been using the *ovirt-4.1-pre* and

Is there any harm if I just install

remove the other two 'pre' repositories from my /etc/yum.repos.d/
? Or is there anything I should be concerned when doing that ?


No harm, thanks for having tested pre releases!
I would wait until 4.1.1 is released just avoiding to get orphaned 
rpms since stable is still at 4.1.0 while pre is at 4.1.1 rc3 right now.


Thanks

Re: [ovirt-users] OVirt new cluster host only logins on one iSCSI

[Duarte Fernandes Rocha]

Hi,

> How to find the relation between "list storagedomains" and "list
> storageconnections"?

To find out which storage connections a specific storage domain is using
you could do:

show storagedomain STORAGE_DOMAIN-ID 

or with curl  via REST API

curl --insecure --user user --request GET 
https://ovirt.host/ovirt-engine/api/storagedomains/STORAGE_DOMAIN_ID

But it does not give the storage connection ID, I used the 

storage-volume_group-logical_unit-address
storage-volume_group-logical_unit-portal

to match them with the storage connection...there might be a way but I
do not know :(

That answerfile is on the shared storage used for the hosted-engine storage
domain inside a configuration volume but, If I'm not wrong, the engine
fetches it when it imports the hosted-engine storage domain but it doesn't
periodically refresh it so I think that if you want to get it stably
changed also for future hosts you have to fix that value in the engine DB.

it's fine.
You can also run
  yum remove ovirt-release41-pre
just to avoid keeping a reference to that repos.

Re: [ovirt-users] How to configure Cloud-init in Guest OS ?

[TranceWorldLogic .]

Hi,


I am trying to create file using same API, as shown below:
--
scontent="Hello World !!"

vm_service.start(
use_cloud_init=True,
vm = types.Vm(
initialization=types.Initialization(
cloud_init=types.CloudInit(
files=[types.File(name="/root/hello.conf",
content=scontent, type="PLAINTEXT")],
),
),
),
)


Can someone help me to understand ? why it is not working.
Or Is that variable "cloud_init=" not handled in ovirt ?

Thanks,

Re: [ovirt-users] Error on Adding Host

[FERNANDO FREDIANI]

Hello Yedidyah and all

I bring you a slightly new information about this issue.

If I have the node SSH port changed to something else other than 22 it is
unable to fetch the fingerprint. I changed it back to 22 and it worked to
fetch the fingerprint but failed again when adding the host with the same
error as before. (Yes I have allowed the port in the node firewall)

Before adding the host I have also cleaned both /root/.ssh/known_host and
/var/lib/ovirt-engine/.ssh/known_hosts

Regards
Fernando

What SDK are you using? I guess that the Python SDK. Did you try this
example:

That should be eough, at least in CentOS. Not sure about Ubuntu.

Note that you are using a quite old version of CentOS, so you may also
be using an old or buggy version of cloud-init. Did you try with latest
CentOS 7?

[ovirt-users] how to attach lvm device to VM ?

[TranceWorldLogic .]

Hi,

I have created LVM partition in host.
I don't want that partition to act as storage domain in ovirt, but I want
to attach that partition to VM.

So I used virsh command to attach device to VM and it was successfully
attached (block device as raw type).
But when I tried to take snapshot of VM from Ovirt, it fail to get
snapshot.

I think it may be due to vdsm as it is not aware of newly attached lvm
device.

Can someone help me to know another way to attach device to VM in Ovirt?
I tried with vdsClient but not got idea or command that will attach device
to VM.

Re: [ovirt-users] virt-manager not able to connect to my ovirt-instance

[Staniforth, Paul]

Hello,

  The VM is running on one of your nodes/hosts and the client 
should be connecting to a port on that machine. The web portal is likely on the 
machine that has the oVirt Engine running on.

Thanks Paul,
I have tried opening it using "remote-viewer", but I get error message as

"Unable to connect to the graphic server /tmp/mozilla_saji0/console.vv
Could not connect to 192.168.59.95: No route to host"

This has something to do with the permission than, route issues, because I can 
access the server through the browser as well as I can ping it also
I have to see what permissions or port blocked at the ovirt server level
Thanks

You should use remote-viewer to connect to the console of the VM, it's in the

Through the browser I am able to see the virtual machines running, is there 
anything else for me to do, for allowing "Virtual Machine Manager" to work

It's really the same, probably it's easier to edit
 /etc/ovirt-hosted-engine/hosted-engine.conf on the two hosts since it's
just a text file.
Please take care that you have to stop all the monitoring domain task in
vdsm and remove all the existing sanlock locks.
Probably the easiest option is to set the host (you can do it one host at
at time keeping running VMs include the engine one on the other) in
maintenance mode from the engine, edit
/etc/ovirt-hosted-engine/hosted-engine.conf
to reflect the spm_id you have in the engine DB and then reboot the host to
ensure that all the locks are gone.

Since 4.0 we cannot hit this kind of issue anymore since the hosted-engine
hosts (but the bootstrap one) should be deployed from the engine and this
ensure that the spm_id is always in sync.

[ovirt-users] VM switched off when migration for host maintenance fails

[Eduardo Mayoral]

Hi,

An interesting thing just happened on my oVirt deployment.

While setting a host for maintenance, one of the VMs running on that
host failed to migrate. Then ovirt-engine for some reason turned the VM
off. Here are the relevant log lines from engine.log:

Now, I understand an VM migration may fail for a number of reasons, but
in that case, shouldn't the VM keep running on the source host? I do not
quite understand what happened here or how to avoid it in the future.

[ovirt-users] Event History for a VM

[Sven Achtelik]

Hi All,

I would need to have an Event-History of our VMs for auditing purposes that is 
able to go back until the moment the VM was created/imported. I found the 
Events Tab in the VM view and found that this is not showing everything to the 
moment of creation. Things that are important for me would be any change in 
CPUs or Host that the VM is pinned to. Are the Events stored in the Engine DB 
and can I read them in any way ? Is there a value that needs to be changed in 
order to keep all Events for a VM ?

Thank you for helping,

Sven

legacy is no longer supported in 4.0 (and not needed/useful since 3.6 already)

[ovirt-users] Ovirt 4.1 USB Api problems

[Adolfo]

Hi,

I don't know if this is the correct place for this question (i hope it 
is  ;-) ).


We are trying to make "enable USB support" work with a machine created 
from python ovirtsdk4 api,


here is the code:

cluster = ovirt.types.Cluster(id=six.binary_type(clusterId))
template = ovirt.types.Template(id=six.binary_type(templateId))
if usbType in ('native', 'legacy'):
usb = ovirt.types.Usb(enabled=True, 
type=ovirt.types.UsbType.NATIVE if usbType == 'native' else 
ovirt.types.UsbType.LEGACY)

else:
usb = ovirt.types.Usb(enabled=False)

memoryPolicy = 
ovirt.types.MemoryPolicy(guaranteed=guaranteedMB * 1024 * 1024)
par = ovirt.types.Vm(name=name, cluster=cluster, 
template=template, description=comments,
type=ovirt.types.VmType.DESKTOP, memory=memoryMB * 1024 * 1024, 
memory_policy=memoryPolicy,

usb=usb)  # display=display,

return api.system_service().vms_service().add(par).id


The cuestion is that the machines gets correctly created, but when we 
try to start the machine, we get an this error (extract from vdsm):


Traceback (most recent call last):
  File "/usr/share/vdsm/virt/vm.py", line 552, in _startUnderlyingVm
self._run()
  File "/usr/share/vdsm/virt/vm.py", line 1994, in _run
self._connection.createXML(domxml, flags),
  File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", 
line 123, in wrapper

ret = f(*args, **kwargs)
  File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 941, in 
wrapper

return func(inst, *args, **kwargs)
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3784, in 
createXML
if ret is None:raise libvirtError('virDomainCreateXML() failed', 
conn=self)

libvirtError: Error XML: Duplicate USB controllers with index 0

The question is, that if to this machine we have created, from 
administration interface, remove an add support for usb, the machine 
works, and the generated XML differs:


This is the difference we have found:

< 
< slot="0x01" type="pci" />

< 
40a38
> slot="0x02" type="pci" />


The "<" are from the non working (created from API call), and the ">" 
are same machine after disabling and enabling again "usb support".


Is this a bug?, if not, ¿How is supposed to be enabled USB support from 
API on VM  Creation?,


By the way, the equivalent code for oVirt 3.x was working without 
problems, the problems arises from 4.0 onwards.



Sorry for the inconveniences, and thank in advance for any help,


Adolfo Gómez

Simon, what is the correct decision? Change vds_spm_id in the engine

It doesn't matter - the order of disk discovery on the SCSI bus (by udev?)
is quite random.
You must use /dev/disk/by-id/scsi-...

Hi list!
When we upgraded our ovirt environment to 4.1 we get the virtio-scsi
interface as default for virtual disks.
We have seen a difference in drive order from when we used the virtio
interface.

Before when we added disks the order of the drives were set by which order
the disks was created.
So if i had 1 disk as os disk it became vda and added a 50 GB disk that
disk became vdb and then added another 8GB disk that became vdc.

But now when i add two additional disks with the virtio-scsi interface like
the above when i reboot the vm the 50GB disk become sdc and the 8GB disk
become sdb even that i created the 50GB disk first?
How is the order decided in the virtio-scsi interface?
What can i do to ensure that the disks come in the order that i create them?

Could you post the XML (virsh -r list, note the domain
number and virsh -r dumpxml $domainnumber) before and after adding the
disks? Need to see whether there are also any iothreads or anything
else.

Could you please execute this command on the engine VM
sudo -u postgres psql engine -c "SELECT vds_spm_id_map.vds_spm_id,
vds.vds_name FROM vds_spm_id_map, vds WHERE vds_spm_id_map.vds_id =
vds.vds_id;"

and ensure that, on all your hosted-engine host, the spm_id values you see
there matches the value you get with
 grep host_id /etc/ovirt-hosted-engine/hosted-engine.conf

Re: [ovirt-users] virt-manager not able to connect to my ovirt-instance

Thanks Paul, 
I have tried opening it using "remote-viewer", but I get error message as 

"Unable to connect to the graphic server /tmp/mozilla_saji0/console.vvCould not 
connect to 192.168.59.95: No route to host"
This has something to do with the permission than, route issues, because I can 
access the server through the browser as well as I can ping it also 
I have to see what permissions or port blocked at the ovirt server level
Thanks

Yes it's ok.
You should also change it in the answer files so if you add new nodes it will 
be set automatically.

Sounds like a general NFS issue, nothing specific to oVirt.

You might want to use normal debugging means - tcpdump, strace, google :-), etc.

I think your last error is because you need the portmapper port (111) open.
You should see this easily with tcpdump or strace.

Also please note that it's not considered a good idea to use one of the
hosts as an nfs server, although some people happily do that. See also:

Re: [ovirt-users] ovirtmgmt bridge creation fails 100% during hosted-engine 4.1 install

[Edward Haas]

Hello Ian,

Please share your vdsm.log, supervdsm.log and Engine logs from the time you
had this failure.
(please specify the date/time you started the process so we can know where
to look in the log)

Thanks,
Edy.

Re: [ovirt-users] virtio-scsi drive order?

Hi list!
When we upgraded our ovirt environment to 4.1 we get the virtio-scsi

We have seen a difference in drive order from when we used the virtio

Before when we added disks the order of the drives were set by which order
the disks was created.
So if i had 1 disk as os disk it became vda and added a 50 GB disk that
disk became vdb and then added another 8GB disk that became vdc.

But now when i add two additional disks with the virtio-scsi interface like
the above when i reboot the vm the 50GB disk become sdc and the 8GB disk
become sdb even that i created the 50GB disk first?
How is the order decided in the virtio-scsi interface?
What can i do to ensure that the disks come in the order that i create them?


Based on their id on the scsi bus. Use /dev/disk-by-id or so and not sdX
which might change.

[ovirt-users] virt-manager not able to connect to my ovirt-instance

[John Joseph]

Hi ,I was able to install ovirt, and I am able to create virtual machines and 
it is running fine, I can see the instance using browser 
But when I try connecting to the ovirt machine using virt-manager I am getting 
the following error 

"Unable to connect to libvirt.
authentication failed: authentication failed
Verify that the 'libvirtd' daemon is running
on the remote host."
Through the browser I am able to see the virtual machines running, is there 
anything else for me to do, for allowing "Virtual Machine Manager" to work 
thanksJoseph John
