Hi Lionel,

Sorry for the delay in replying you.

If it's possible from your side, syncing the data and destroying old disk
sounds about right.

In addition, it seems like you're having this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1509629
And it was fixed for version 4.1.9. and above.



*Regards,*

Re: [ovirt-users] Cannot activate storage domain

[Bruckner, Simone]

Hello, I apologize for bringing this one up again, but does anybody know if 
there is a change to recover a storage domain, that cannot be activated?

Thank you,

Hi all,

  I managed to get the inactive storage domain to maintenance by stopping all 
running VMs that were using it, but I am still not able to activate it.

Trying to activate results in the following events:

For each host:
VDSM  command GetVGInfoVDS failed: Volume Group does not exist: 
(u'vg_uuid: 813oRe-64r8-mloU-k9G2-LFsS-dXSG-hpN4kf',)

And finally:
VDSM command ActivateStorageDomainVDS failed: Storage domain does not exist: 
(u'b83c159c-4ad6-4613-ba16-bab95ccd10c0',)

Is there anything I can do to recover this storage domain?

Thank you and all the best,

Hi,

  we are still struggling getting a storage domain online again. We tried to 
put the storage domain in maintenance mode, that led to "Failed to update OVF 
disks 809cc8d7-7687-46cf-a342-3be48674a9b3, OVF data isn't updated on those OVF

Trying again with ignoring OVF update failures put the storage domain in 
"preparing for maintenance". We see the following message on all hosts: "Error

Querying the storage domain using vdsm-client on the SPM resulted in

Betreff: [ovirt-users] Cannot activate storage domain

Hi all,

  we run a small oVirt installation that we also use for automated testing 
(automatically creating, dropping vms).

We got an inactive FC storage domain that we cannot activate any more. We see 
several events at that time starting with:

VM perftest-c17 is down with error. Exit message: Unable to get volume size for 
domain b83c159c-4ad6-4613-ba16-bab95ccd10c0 volume

Trying to activate the strorage domain results in the following alert event for 
each host:

VDSM  command GetVGInfoVDS failed: Volume Group does not exist: 
(u'vg_uuid: 813oRe-64r8-mloU-k9G2-LFsS-dXSG-hpN4kf',)

And after those messages from all hosts we get:

VDSM command ActivateStorageDomainVDS failed: Storage domain does not exist: 
(u'b83c159c-4ad6-4613-ba16-bab95ccd10c0',)

Checking the hosts with multipath -ll we see the LUN without errors.

We run oVirt 4.2.1 on CentOS 7.4. Hosts are CentOS 7.4 hosts with oVirt 
installed using oVirt engine.
Hosts are connected to about 30 FC LUNs (8 TB each) on two all-flash storage

[ovirt-users] The timezone in the guest differs from configuration (Windows)

My windows VMs have this error, but the time zones are setup correctly.

In engine, the VM shows: "Hardware Clock Time Offset: Pacific Standard Time"
In Windows, doesn't matter if I leave the time zone automatic or manually

I need to create user accounts in oVirt that can only manage a specific set
of VMs and I don't want them to see any other ones.
example:
User1 can only see VM1, VM2, VM3, VM4
User2 can only see VM5, VM6, VM7
Admin can see all of them.
How do I accomplish this?

[ovirt-users] ovirt Node 4.2.1 on 2 node : problem with ha broker and HE storage

[Nicolas Vaye]

Hello,


I'd installed oVirt Node 4.2.1 on two host, i'd deployed HE on the first, via a 
storage NFS.
The administration portal seem to be OK but i can't see the HE VM, the portal 
indicate there is one VM, but impossible to get it into the list of the VM.
I can't see the storage that host the HE-VM too.
Where is the problem ?

I'd added the second host into the cluster and i haven't the option to deploy 
the HE into it during the "add Host" operation.
After added the second node, i can put into maintenance mode and then reinstall 
with the option DEPLOY for HE but the result is :
"Cannot edit Host. You are using an unmanaged hosted engine VM. Please add the 
first storage domain in order to start the hosted engine import process."



The logs for the first node indicate this error (very often, every ~ 30sec) 
below :

ovirt-ha-broker ovirt_hosted_engine_ha.broker.status_broker.StatusBroker.Update 
ERROR Failed to read state. Traceback (most recent call last): File 
"/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/broker/status_broker.py",

With this problem, i can't move the HE vm on the second host. so there is no HA.

Thanks.

Hello,

I found this KB : https://bugzilla.redhat.com/show_bug.cgi?id=1529607

No, the script that packs the OVA is executed with root permissions.

The path is the path to an export domain ?

Not necessarily.

The skipped part above is the most interesting one that may enable us to
investigate the error, can you share it? it would be best to file a bug [1]
and add the full log as an attachment (that can be made private if needed,
btw).

I've never used it, but https://www.bareos.org/ could be a good product.
It isn't specific for VMs, but it can help.

Re: [ovirt-users] Open source backup!

[Niyazi Elvan]

Hi,

If you are looking for VM image backup, you may have a look at Open Bacchus
https://github.com/openbacchus/bacchus

Bacchus is backing up VMs using the oVirt python api and final image will
reside on the Export domain (which is an NFS share or glusterfs) in your
environment. It does not support moving the images to tapes at the moment.
You need to use another tool to stage your backups to tape.

Hope this helps.

Note that support for Skylake-Server is already in oVirt 4.2.2, once you’re 
running on a hypervisor which supports that(e.g. RHEL 7.5 beta) it should work, 
when you run on the exsiting 7.4 it just won’t work (the option is there 
though, and we separated the generic former “Skylake” to Skylake-Client and 
Skylake-Server)

Re: [ovirt-users] oVIRT 4.1 / iSCSI Multipathing

[Sergei Hanus]

Hi, Nicolas.
As long, as you are able to set up two separate iscsi sessions, which are
bount to two separate paths - multipath driver will handle the rest.
As I understand, Yaniv is talking about iscsi bonding, which is a bit more
broad sort of multipath (per description -
https://www.ovirt.org/documentation/admin-guide/chap-Storage/) - it creates
all possible paths between all possible initiators and targets within bond.
Personally, I don't think it's necessary - it's always better to control
the connections the way you described - two vlans, each vlan contains one
server NIC and one storage NIC, that's it.

 Sergei.

We'll need more details on the VM configuration. I assume you are using raw
(and not qcow2), using virtio or virtio-SCSI, enabled IO threads, etc.
What are you using the measure the performance?

Re: [ovirt-users] Any Kind of Storage IO Limitation?

[Thomas Fecke]

Hey Yaniv,

thanks in advance

ethtool eno2 | grep Speed

always brings up 10.000. So i tought there is maybe a config File in ovirt that 
change it or something.

Or will it use the OS information direct?

Im not sure why the VM´s are getting slow. But when I run an Monitor tool to 
check the Bandwith it never excet 1000. Maybe he just don’t need more for the 
Copy Job

I have no explanation

fact ist – when I deploy the same Template about 10-15 Times they are getting 
rly slow.

The RAM and CPU is morgen then 70% Free.



Ill tried to Stress the Storage a bit.

Opened nload and created some VM´s, created Templates, created Pools and and and

An I was wrong:

Max: 8.09 GBit/s

I can life with that. The Performance issues sees to be Gone for now. Maybe it 
was just the 4.2 Upgrade. I have no idea

But everything seems to work fine. Sorry for wasting your tim e

You should use CA certificate if you use default one it's:

Re: [ovirt-users] oVIRT 4.1 / iSCSI Multipathing

[Nicolas Ecarnot]

Hello,

[Unusual setup]
Last week, I eventually managed to make a 4.2.1.7 oVirt work with 
iscsi-multipathing on both hosts and guest, connected to a Dell 
Equallogic SAN which is providing one single virtual ip - my hosts have 
two dedicated NICS for iscsi, but on the same VLAN. Torture-tests showed 
good resilience.


[Classical setup]
But this year, we plan to create at least two additional DCs but to 
connect their hosts to a "classical" SAN, ie which provides TWO IPs on 
segregated VLANs (not routed), and we'd like to use the same 
iscsi-multipathing feature.


The discussion below could lead to think that oVirt needs the two iscsi 
VLANs to be routed, allowing the hosts in one VLAN to access to 
resources in the other.

As Vinicius explained, this is not a best practice to say the least.

Searching through the mailing list archive, I found no answer to 
Vinicius' question.


May a Redhat storage and/or network expert enlighten us on these points?

Regards,

I’ve skipped this message entirely yesterday. So this is per

With regular storage it is quite easy to achieve using 'iSCSI bonding'.
I think the Dell storage is a bit different and requires some more 
investigation - or experience with it.

 Y.


Yaniv, thank you for answering this. I’m really hoping that a solution 
would be found.


Actually I’m not running anything from DELL. My storage system is 
FreeNAS which is pretty standard and, as far as I know, iSCSI 
practices dictates segregate networks for proper working.


All other major virtualization products supports iSCSI this way: 
vSphere, XenServer and Hyper-V. So I was really surprised that oVirt 
(and even RHV, I requested a trial yesterday) does not implement ISCSI 
with the well know best practices.


There’s a picture of the architecture that I take from Google when 
searching for ”mpio best practives”: 
https://image.slidesharecdn.com/2010-12-06-midwest-reg-vmug-101206110506-phpapp01/95/nextgeneration-best-practices-for-vmware-and-storage-15-728.jpg?cb=1296301640


Ans as you can see it’s segregated networks on a machine reaching the 
same target.


In my case, my datacenter has five Hypervisor Machines, with two NICs 
dedicated for iSCSI. Both NICs connect to different converged ethernet 
switches and the iStorage is connected the same way.


So it really does not make sense that a the first NIC can reach the 
second NIC target. In a case of a switch failure the cluster will go 
down anyway, so what’s the point of running MPIO? Right?


Thanks once again,
V.

[ovirt-users] Users/Groups Permissions

[Markus.Schaufler]

Hi!

Still new to oVirt and got another question:

I have many Windows and Linux VMs and created for each the Windows and Linux 
machines two Usergroups (limited and admins).
Now I want to grant the groups according permissions to according VMs. How can 
I do this without clicking through every VM manually (e.g. by mark several vms 
in the UI and manage their permissions or via CLI)?

Many thanks in advance,

Re: [ovirt-users] Installation using virtual machines

[Fred Rolland]

Hi,

The ovirt engine can be run in a virtual engine. Look for "hosted engine".

What do you mean by "guests" ?
If you mean the hosts running the VMs, it is possible but not recommended.
Real hardware is the best way.

Re: [ovirt-users] Ovirt 4.2.1 Storage with Fibre Channel Protocol

[Fred Rolland]

Hi,

All hosts in the Data Center should have access to the storage.
Think of the DC as a migration domain. If one of the hosts fails and you
need to migrate the VMs to another host, the VMs disks needs to be
available in the new host.

You cannot use the same LUN in different domains.
Either ask the storage administrator to split the LUN into 3 smaller LUNs
or maybe use an NFS server for the ISO domain.

Fred

Re: [ovirt-users] Troubleshooting VM SSO on Windows 10 (ovirt 4.2.1)

[Cristian Mammoli]

Anyone???

Hi, I'm trying to setup sso on Windows 10, vm is domain joined, has
agent installed and credential provider registered.Of course I setup an
AD domain and the vm has sso enabled

Whenever I log to the user portal and open a VM I'm presented with the
login screen and nothing happens, it's like the engine doesn't send the
command to autologin.

In the agent logs there's nothing interesting but the communication
between the engine and the agent is ok: for example the command to
lock-screen on console close runs and works:

Dummy-2::INFO::2018-03-01
09:01:39,124::ovirtagentlogic::322::root::Received an external command:
lock-screen...

This is an extract from engine logs when I login in the user portal and
start a connection:

When clicking on one of those machines and selecting 'Cancel

On the vdsm side I see:

So no error on the vdsm side log.


Interesting.  The messages above indicate that the VM was attempted 
to
migrate, but the migration got temporarily rejected on the 
destination
due to the number of already running incoming migrations (the limit 
is 2

incoming migrations by default).  Later, Vdsm was asked to cancel the
outgoing migration and it successfully set a migration canceling 
flag.

However the action was reported as an error to Engine, due to hitting
the incoming migration limit on the destination.  Maybe it's a bug, 
I'm
not sure, resulting in minor confusion.  Normally it shouldn't 
matter,
the migration should be canceled shortly after anyway and Engine 
should

be informed about that.

However the migration apparently wasn't canceled here.  I can't say 
what
happened without complete Vdsm log.  One of possible reasons is that 
the
migration has been waiting on completion of another migration 
outgoing
from the source (only one outgoing migration at the time is allowed 
by

default).  In any case it seems the migration either wasn't actually
started at all or it just started being set up and that has never 
been

completely finished.



I'm attaching the log. Basically the storage backend was restarted by 
fencing
and then this issue happened. This was on 26/02 at about 08:52 (log 
time).


Thank you for the log, but VMs are already “migrating” at its 
beginning,

there had to be some problem already earlier.


I already tried restarting ovirt-engine but it didn't work.


Here the problem is clearly on the Vdsm side.

Could someone shed some light on how to cancel the migration status 
for

these
machines? All of them seem to be running on the same host.


Did the VMs get unblocked in the meantime?  I can't know what's the


No, they didn't. They're still in a "Migrating" state.

actual state of the given VMs without seeing the complete Vdsm log, 
so
it's difficult to give a good advice.  I think that Vdsm restart on 
the
given host would help BUT it's generally not a very good idea to 
restart

Vdsm if any real migration, outgoing or incoming, is running on the
host.  VMs that aren't actually being migrated (despite being 
reported
as migrating) at all should simply return to Up state after the 
restart,

but VMs with any real migration action pending might get return to Up
state without proper cleanup, resulting in a different kind of mess 
or
maybe something even worse (things should improve in oVirt 4.2, but 
it's

still good to avoid Vdsm restarts with migrations running).



I assume this is not a real migration as it has been in this state for 
several

days. Would you advice restarting vdsm in this case then?


I'd say try it.  Since nothing has changed for several days, restarting
Vdsm looks like appropriate action at this point.  Just don't make a
habit of it :-).



Thanks, that made it.

Regards.

[ovirt-users] oVirt network tries to reassign my bridge address to herself

[Anastasiya Ruzhanskaya]

Hello!
I have two VM - they are machines on which I test installation. I don't
want any clusters, advanced features. My goal is two connect engine and
host, shut down everything,  then turn on and have right configuration.

However my VMs are connected via bridge, and oVirt also use another bridge
to connect them. Because of this on startup I have a problem, that two
bridges are trying to assign the same address.

What can be done in this case?

[ovirt-users] Problem Storage Iscsi

[João Floriano - Magnet]

Hello everyone!

I am facing the following problem with ovirt 4.2.1, out of nowhere all
virtual machines are paused and only return operals if log in via ssh on
the host and execute a "virsh destroy domain", it is necessary to
reactivate disk and network after this process. In the events I get the
following message: VM X has been paused due to storage I / O problem.

Currently I have iscsi storage configured on a server with target and based
on some test I did not identify problems of communication of the hosts to
the storage

can you help me?

[ovirt-users] Ovirt 4.2.1 Storage with Fibre Channel Protocol

[Sérgio Marques]

Hello,

I'm new in Ovirt, loving it, but i'm having some doubts when it comes to
add FCP Storage. I have two clusters, one called Production and the other
Development, each cluster with two nodes and i want to configure Data
Domain. My doubts are:

1 - Every nodes must have connection to de FCP? If only de SPM have it, if
it falls, who can connect to the storage?

2 - I have only one LUN in EVA HSV300 for me and i want to add three
Storage Domains (Data, ISO e Export). Is it possible? How? This is because
when i add data storage domain and choose the only LUN available it warn me
that all data is going to be lost "This operation might be unrecoverable
and destructive"

3 - Any advice about best practices about implementation?

Thanks
