Adding Phillip and Doron ( Bug 1363900
 - Specific Host(s)
radio button doesn't work) . I see bug has been targeted to 4.0.7 but maybe
some of your questions may be answered earlier.

 ok, I will raise a bug. Yes it is very frustrating just having button
 not work without explanation.
 I don't know if this is related, the new host that I am having troubles
 with is running 4.0.1.1-1,
 other other host is running 4.0.0.6-1

 I was planning on migrating VMs then upgrade the older host.
 Also Cluster is still in 3.6 mode, also waiting for upgrade of older
 node.
 All storage domains are on older node, its the NFS server.


 hmm, just retried migration so I could get vdsm logs from both hosts.
 1 VM worked, the other 3 failed.
 And I still can't assign VMs to new node.

 VM that worked: f4cd4891-977d-44c2-8554-750ce86da7c9

 Not sure what's special about it.
 It and 45f4f24b-2dfa-401b-8557-314055a4662c are clones from same
 template.


 Attaching logs from 2 nodes and engine now.

Did you happen to save the logs? They might reveal the issue.

[ovirt-users] Choose default auth backend

[James Michels]

Greetings,

We have several auth backends (LDAP, AD...), and we'd like to establish de
default one to one of them. 'internal' seems to be the default now.

Is there a way to override the default backend on the login page?

This is ovirt 4.0.2

Thanks

yes, we have such feature since 4.0.
You can see details in doc text of following bug:

 https://bugzilla.redhat.com/show_bug.cgi?id=1296274

Doc text:
With this update, a new configuration variable, 
ovirt.engine.aaa.authn.default.profile, has been added to the authn 
configuration file. Setting this variable ensures that the profile 
drop-down menu on the login page defaults to the selected profile. To 
configure this feature, add ovirt.engine.aaa.authn.default.profile to 
the authn configuration file for a selected profile and set the value to 
true then restart the ovirt-engine service. If the 
ovirt.engine.aaa.authn.default.profile variable is not defined in the 
authn configuration file the drop-down menu defaults to internal.




This is ovirt 4.0.2

Thanks

James

This is the URL yuo want - It contains the builds based on the latest
stable release.

Tho I see that it wasn't updated lately.
Sandro, can we publish a new ISO for 4.0.3?

In the mean time you can take the iso from
http://jenkins.ovirt.org/job/ovirt-node-ng_ovirt-4.0_build-artifacts-el7-x86_64/
Which is building the stable isos

Yep, these are nightly builds, and probably unstable.

4.0.2 iso wasn't ready and missed the release. 4.0.3 is currently under
testing to be released this week if no blockers will be found. It's
available here:
http://resources.ovirt.org/pub/ovirt-4.0-pre/iso/ovirt-node-ng-installer/

[ovirt-users] Problem starting VMs

I am unable to launch vms on one of my host.  The problem is vm is 
stuck at "waiting for launch" and never comes up. I see the following

Typically it takes at least 5 minutes with abnormal monitoring
conditions before engine will make a host non-operational,
is this realy superfast?

I think the main issue was mixing of storage monitoring and lvm
refreshes, unneeded serialization of lvm commands, and bad
locking in engine side. The engine side was fixed in 3.6, and
the vdsm side in 4.0.
See https://bugzilla.redhat.com/1081962

In rhel/centos 7.2, lot of lot of multipath related issues were fixed,
and ovirt multipath configuration was fixed to prevent unwanted
io queuing with some devices, that could lead to long delays and
failures in many flows. However, I think our configuration is too
extreme, and you may like to use the configuration
in this patch:
https://gerrit.ovirt.org/61281

I guess trying 4.0 may be too bleeding edge for you, but
hopefully you will find that your iscsi setup is much more reliable
now.

Please file bugs if you still have issues with 4.0.

[ovirt-users] Upgrade from CentOS 6.8 (oVirt 3.5) to CentOS 7 (oVirt 4.0)

[Fedele Stabile]

I would upgrade my CentOS 6.8 to 7 on my cluster of 5 ovirt nodes
(actually I'm running oVirt 3.5 and glusterfs 3.7). 
Anyone has experienced troubles for this upgrade?

[ovirt-users] More Hosted Engine 3.6 Qusetions

[C Williams]

Hello,

I have found that I can import thin-provisioned VMs from VMWare ESXi into
an oVirt (3.6 Hosted-Engine) iSCSI  storage domain as thin-provisioned VMs
by doing the following :

1 . Import the thin-provisioned VMWare VM into an NFS storage domain.
2.  Export the thin-provisioned VM from the NFS storage domain.into the
oVirt Export domain.
3.  Import the thin-provisioned VM into an iSCSI Storage Domain from the
oVirt Export domain

Is there a simpler way to do this using the 3.6 Import capability ? Or, do
we need to follow the above procedure to get VMs into oVirt from VMWare as
thin-provisioned VMs ?

Thank You For Your Help !

[ovirt-users] Uncaught exception issue

[James Michels]

Hi,

I'm trying to de-obfuscate an uncaught exception error and I've reached
this page for instructions:
http://www.ovirt.org/uncategorized/engine-debug-obfuscated-ui/

However, images are broken and its kind of difficult to follow instructions
without seeing them.

Could you please guys fix it?

Thanks

Why not import the thin-provisioned VMWare VM directly into a block storage
domain?

What do you get in this case?

Udev in 6.8 seems to be broken, breaking block storage.
See https://access.redhat.com/solutions/2576511

I would avoid this upgrade, or test it on one hypervisor and report
ovirt bug.

Upgrading to 3.6 or 4.0 and centos 7.2 is recommended.

Since 3.6.5 or 6, the deobfuscation happens automatically if you installed the 
mapping files described in the wiki page. You can look at UI.log and it should 
be deobfuscated. It is important that the rpm version of your engine match the 
rpm version of the mapping files.

my ultimate goal would be to have a cluster with last version of Centos

so my question is
what are the best steps:
first upgrade Centos of first upgrade oVirt?

You cannot upgrade ovirt on centos 6, since 3.5 is the last version
supporting it.

Best would be to upgrade the hypervisors to centos 7, which will
pull latest ovirt anyway.

> The ovirt-engine is hosted

Upgrading the hosted engine vm is not related and more delicate,
It should be possible using hosted engine setup.

Adding Simone to add more info on that.

I misread your question - you seems to already run centos 6.8.

I guess you are not using block storage (iSCSI/FC), do you?

On 4.0 we have a new --upgrade-appliance feature on hosted-engine-setup:
 
https://www.ovirt.org/develop/release-management/features/hosted-engine-migration-to-4-0/

The tool will ask you to take a backup pf your engine DB with
engine-backup, then the tool will re-deploy a 4.0/el7 appliance
automatically injecting there the backup of your 3.6 engine.
The supported path is 3.6 -> 4.0 so you have also to do 3.5 -> 3.6 before that.

[ovirt-users] How to import a qcow2 disk into ovirt

Re: [ovirt-users] How to import a qcow2 disk into ovirt

[Maor Lipchuk]

Hi lifuqiong,

There are several ways to import disks into oVirt

Does the disk contains any snapshots?
if not, the disk file can be copied to the storage domain and you can
register it using the Register button (see
https://bugzilla.redhat.com/show_bug.cgi?id=1138139)

You can also take a look at the image-uploader, see
http://www.ovirt.org/develop/release-management/features/storage/image-upload/

What is the use case that you want to do? What is the origin of the disk
(Was it an oVirt disk?), as asked before, does the disk includes any
snapshots.

Regards,
Maor

Re: [ovirt-users] 3.6 : Hosted engine High Availability

[Alexis HAUSER]

Thank you for your explanations, this is very clear now :)



Actually I was confused because "this host" is used in several different 
contexts, if I am right :

1 - For the engine (which is not a host, but a guest) :
"Enter the name which will be used to identify this host inside the 
Administrator Portal [hosted_engine_2]"

2 - For the Host
It asks the same things for the FQDN, but not for the engine this time, for the 
real "host"

Please confirm me this, so I will know if I have to open a bug for this.



Now my error is the following :

"[ ERROR ] Failed to execute stage 'Closing up': Specified cluster does not 
exist: Default"

I think it assume I didn't change the name of the default cluster after 
deploying the first host. I will try to workaround with this by renaming the 
datacenter
I will check if a bug if open on the bugzilla about this and if not I'll open 
one.

'Please provide the address of THIS host.' means that you have to
enter/validate the address of the host you are going to add (the host
where you are running hosted-engine --deploy command).

Let's try to recap:
the fqdn of your engine VM is 'vm-rhemgr.mydomain.com',
the fqdn of your host is currently 'localhost.localdomain' but it's
not acceptable (try to run 'ssh localhost.localdomain' on the engine
VM and see where are you getting...)

So you have just to configure a valid fqdn on your additional host
(something like 'my2ndhost.mydomain.com') and confirm it when asked by
that question.

Normally we suggest to rely on a properly configured DNS; you can just
work entering values under '/etc/hosts' but it's up to you to properly
maintain it:
- the engine VM should be able to resolve the address of all the hosts
to contact them: this is not true in your env, with
'localhost.localdomain' your engine VM will not reach your host...
- each host should be able to resolve the address of all the other
hosts and also the address of the engine VM: this is not true in your
env as I read 'RuntimeError: vm-rhemgr.mydomain.com did not resolve
into an IP address'

[ovirt-users] How to manually restore backup

[Hanson]

Hi Guys,

Just wondering what the proper way to restore a backup to a hosted-engine?

I've tried doing the deploy, then cleanup, and backup --mode=restore, 
but then engine-setup needs internet access. (which it doesn't have)


Is there a way to restore the backup over the current data of a 
currently deployed new host?


ie like a --mode=restore --option=force ?

or is there another way to restore?


Thanks,

Hanson

No, in both the case it's referring to the host you are going to add to
your engine (the host where you are running hosted-engine --deploy): the
first one is a label to easily identify your host, the second one the
address to reach it.

You can try 'engine-setup --offline'.

No, but you can try running 'engine-cleanup'.

Also, engine-backup only checks for the databases, not files. So you can try:

service postgresql stop
rm -rf /var/lib/pgsql/data
then restore again.

Thanks, then it means only the default label is wrong, right ? It should be 
[host_2] (refering to the host itself) instead of [hosted_engine_2] (refering 
to the engine itself), no ?

We are proposing  hosted_engine_1 for the first host involved in
hosted_engine and hosted_engine_n for additional hosts.
A lot of users got confused by this so we are going to remove and simply
use by default the host address as its label; the user will always be able
to rename it from the engine.

[ovirt-users] Import of exported VMware VM fails

[Cam Mac]

Hi,

I've use ovftool to create an .ova of a VMWare guest (in this case W2012),
and then have converted it with virt-v2v, outputting to the oVirt export
domain (virt-v2v -i ova /space/w2012-test.ova -o ovirt -os
ovirt-engine:/mnt/export-vm -of qcow2). This appears to work, though it
reports a warning:

I can then see the exported VM available for import in the oVirt GUI. When
I import it however, it just says it fails to import, and having a look at
the engine log I can't see what is wrong specifically:

This was fixed in 4.18.0:

These warnings should show only when you start a vm - are you starting

First step, you have to edit
/etc/ovirt-hosted-engine/hosted-engine.conf on all your hosted-engine
hosts to ensure that the storage field always point to the same entry
point (host01 for instance)
Then on each host you can add something like:
mnt_options=backupvolfile-server=host02.yourdomain.com:host03.
yourdomain.com,fetch-attempts=2,log-level=
WARNING,log-file=/var/log/engine_domain.log

Then check the representation of your storage connection in the table
storage_server_connections
of the engine DB and make sure that connection refers to the entry point
you used in hosted-engine.conf on all your hosts, you have lastly to set
the value of mount_options also here.

Please tune also the value of network.ping-timeout for your glusterFS volume
to avoid this:
 https://bugzilla.redhat.com/show_bug.cgi?id=1319657#c17

[ovirt-users] unable to update to 4.0

[Jeb Baxley]

Hi All,

I have Ovirt 3.6.7 installed and running.  However, when attempting to
update to 4.0 I receive this error when running engine-setup.

Failed to execute stage 'Setup validation': Trying to upgrade from
unsupported versions: 3.5

I find this pretty strange as I haven't run 3.5 in a long time and can
confirm that I'm running 3.6.7.

[ovirt-users] vdsm memory consumption (ovirt 4.0)

[Federico Alberto Sayd]

I have issues with my ovirt setup related to memory consumption. After
upgrading to 4.0 I noted a considerable grow in vdsm memory consumption.
I suspect that the grow is related to a memory leak.

When I boot up the system and activate the host the memory consumption
is about 600MB. After 5 days running and host in maintenance mode the
memory consumption is about 1,4 GB.

I need to put my hosts in maintenance and reboot to free memory.

Can anyone help me to debug this problem?

Hi,

Unfortunately not. Engine log may be there, if it is not rotated

I have two more servers of the same configuration. Let me try & simulate

Hi,

The migration is working fine with Cluster Switch set to "Legacy"
Mode.

But I have run into a different problem. Yesterday, for some
reason, I had to restart the hosts. But the Hosts never came
online. Hosts were constantly in Non Responsive state. I manually
fenced it, and Vds command timed out.

I found that NIC was down for some reason. I brought it up and
again fenced the hosts. Again the Vds command timed out. I
manually attempted to restart the VDSM service, but host reported
there is no such service. Starting VDSMD service resulted in failure.

Finally, I had to forcefully remove the hosts, reinstalled base
(CentOS 7) on hosts and re-added them to oVirt with the storage
domain intact. All hosts, storage domains went online and all VMs
were intact.

Post reinstallation, I set the Cluster Switch mode to "Legacy" and
tried migration and it worked fine.

I fail to understand what went wrong while rebooting the hosts.

installed properly and when I attempted to migrate the
running VM, the migration failed.

Engine log, Host 1 log and Host 2 logs are attached for
your reference. Since logs are running into several
MBs, I have compressed them and attached here.

Can someone help us to solve this issue?

This message means that you have one or more cluster/dc with 3.5
compatibility version. You can check the setup log for more details. Please
upgrade them to 3.6 and try again.

Hi, ovirt 3.6 is supported only on Fedora 22.
oVirt 4.0 supports Fedora 23 as tech preview.
oVirt master (will become 4.1) support Fedora 24 as tech preview.

Your help testing what will become oVirt 4.1 on Fedora 24 will be really
appreciated.
Instructions on how to install master nightlies are here:

Re: [ovirt-users] Import of exported VMware VM fails

[Shahar Havivi]

Check for permissions,
All the directory hierarchy and the images as well as the ovf needs to reached
by the vdsm user, its best to change the owner to vdsm:kvm (e.g. 36:36).

Re: [ovirt-users] How to import a qcow2 disk into ovirt

[Amit Aviram]

Hi
Actually, if you have the latest oVirt 4, you can just do that from the UI.
just go to disks tab and select "upload" -> "start".

Before doing that, make sure to make your browser trust oVirt's CA by
downloading its CA certificate from:
https://{your_engine's_URI}/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA


Let me know if that's works for you.

You can restart vdsm (systemctl restart vdsmd) instead, running vms
are not effected by this.

We had a memory in vdsm-4.18.5, fixed  in vdsm-4.18.11. Since you
are running 4.18.11, there may be another leak.

Please enable health monitoring by creating
/etc/vdsm/vdsm.conf.d/50-health.conf

[devel]
health_monitor_enable = true

And restart vdsm.

Please run with this setting for couple of hours, maybe one day,
and then share the vdsm logs from this timeframe.

You may disable health monitoring by setting

[devel]
health_monitor_enable = false

Or by renaming or deleting this configuration file:

/etc/vdsm/vdsm.conf.d/50-health.conf.disabled
