[ovirt-users] LDAP

[Koen Vanoppen]

Hello everybody,

We updated our ovirt to 3.5, but now we see some errors concerning LDAP. I
already searched oonline for a guide for the AAA config, but can't seem to
find something...
Does anybody already has a clear how-to for the AAA config?

This is the error we get sometimes in our engine.log (we are still able to
login with ldap btw):

2014-11-20 06:42:06,539 ERROR
[org.ovirt.engine.extensions.aaa.builtin.kerberosldap.DirectorySearcher]

Hi,

Live snapshot indeed works, only live merge is not working. I guess we will 
have to wait until is available on CentOS.
Thanks!

Hm could it be you mix up live snapshot and live merge? Live snapshot

works since 3.4.3 quite will. Live merge however is still unsupported as

I think it requires some quite new stuff from libvirt. It will

eventually work on EL7 [1].

CCing Yair he might have a clue.

Would you like to test the next generation of LDAP provider? It should be much 
simpler than current provider, it uses only LDAP protocol, and enable you to 
customize almost everything.

It is available in ovirt-engine-3.5-snapshots repository, package name is 
ovirt-engine-extension-aaa-ldap, documentation is available within package and 
here[1], I will be glad to help if you decide to check it out.

Regards,
Alon Bar-Lev.

So i understand this is not 100% right?
Can you share more on the upgrade? Are you working with openldap? Have you 
upgraded anything else?

Re: [ovirt-users] LDAP

[Koen Vanoppen]

It's a complete update of ovirt 3.4.2 to 3.5. No DWH and reports installed
on the engine. Everything works fine. Even Ldap. It's just the error that
sometimes shows up now since the update. Ldap comes from active directory
(windows server 2012).

Well, it is new... as any new component first should be tested in 
semi-production, if it meets your needs you can promote.

It also provide much better performance.
I could release this now, but I am waiting to one first of ovirt-engine-3.5.1 
to make it easier to deploy,
And of course I would like more people to test this and report back results.

Re: [ovirt-users] LDAP

[Koen Vanoppen]

If it get's to ovirt 3.5.1 that indeed would be great. We don't have any
issues for the moment, so we can wait for that release. It's only a error
without problems :-).

Thanks in advance.

Just a guess since you do not mention this step; after an engine update 
it is *required* to run 'engine-setup'. See [1] for more info about 
upgrading oVirt engine.

Re: [ovirt-users] Gluster command[] failed on server ovhost1

[Fumihide Tani]

Hello Kanagaraj,

Resolved!
I have done yum's undo and retried yum update again.
engine.log's gluster errors are disappeared and now oVirt is working well.

Thank you so much.

Do you see any errors in /var/log/ovirt-engine/engine.log?

Also check if glusterd and vdsmd services are running on the servers.



My oVirt servers and VMs are not operational now.

[ovirt-users] Billing solution

[Nikos Zaharioudakis]

Hi list,

Is there a recommendation for any billing solution or the end user just
have to take the reports / create custom from the data-warehouse reporting
portal?
Of course I guess there is the option to ask over the API, but if someone
has invented the wheel ...

Best,

Nikos

Re: [ovirt-users] Gluster command[] failed on server ovhost1

[Fumihide Tani]

Hi, Daniel

Trouble was resolved by yum undo and retring yum update again.
Perhaps my trouble was different from engine update issue,
yum update installs only gluster modules not engine modules.

thanks a lot,
Fumihide

Please have a look on this lecture I had gave on hangouts :

I believe that it will make you understand the flow and the configuration

Yes, this is the point were you customizing the new agent 
this is basically a 2 step task

1) server side, you will have to add your fencing scripts and verify that it 
installs correctly in /usr/sbin/
   it must be called fence_
   it must obey to fence-agents package script parameters defined in
   https://fedorahosted.org/cluster/wiki/FenceArguments

2) engine side : use engine-config to configure your new agent

If you use direct LUN option for a VM image, you can take a snapshot of that 
LUN on the SAN and attach it as another direct LUN and eventually boot from 
that. Do you really need to take an online snapshot of the whole storage domain 
with all the VM in a single shot?

Currently there is no billing solution, but you can open an RFE bug for it.
Please write in the description the use case and requirements in detail,

Thank you both for your contributions!

>From a software design PoV, we'd better not duplicate the extnet code.
If a bug is found and fixed in extnet,
http://www.ovirt.org/VDSM-Hooks/network-nat would have to be updated as
well.

It would be more elegant to ship an additional script with an independent
custom property, say "ovs_portgroup". This script would run after extnet
does, and would add the portgroup attribute to to the proper element.

Who's posting this to gerrit first?

Dan.

I agree with a separate custom property, but I think that we could make
extnet look for it too and set the port group itself. It would be backwards
compatible and simpler.

In particular, if you are willing to bill based on network/storage/cpu
usage, ovirt-engine does not yet keep track on that.

We are planning to implement part of it

Bug 1066570 - [RFE] Report actual rx_byte instead of a false rxRate

in ovirt-3.6, so that VM rx/tx consumption is accumulated, tracked, and
reported by the Engine.

Re: [ovirt-users] Cumulative VM network usagePERIOD_TIME

[Amador Pahim]

Hi Lior,

Thank you for this. Indeed I have seen multiple requests for this. I 
also have a bugzilla for it: 
https://bugzilla.redhat.com/show_bug.cgi?id=1108144. Some comments bellow.

Hello,

The need to monitor cumulative VM network usage has come up several
times in the past; while this should be handled as part of

I've written a small Python script that monitors those statistics,
attached here.

The script polls the engine via RESTful API periodically and dumps the
up-to-date total usage into a file. The output is a multi-level
map/dictionary in JSON format, where:
* The top level keys are VM names.
* Under each VM, the next level keys are vNIC names.
* Under each vNIC, there are keys for total 'rx' (received) and 'tx'
(transmitted), where the values are in Bytes.

The script is built to run forever. It may be stopped at any time, but
while it's not running VM network usage data will "be lost". When it's
re-run, it'll go back to accumulating data on top of its previous data.


This could be mitigated if along with rx and tx data, vdsm was reporting 
a timestamp reflecting the time when data was collected. So, even with 
gaps, we should be able to calculate the cumulative information.




A few disclaimers:
* I haven't tested this with any edge cases (engine service dies, etc.).
* Tested this with tens of VMs, not sure it'll work fine with hundreds.
* The PERIOD_TIME (polling interval) should be set so that it matches
both the engine's and vdsm's polling interval (see comments inside the
script), otherwise data will be either lost or counted multiple times.
 From 3.4 onwards, default configuration should be fine with 15 seconds.


Here we have another issue. In 3.4, 15 seconds is fine... backend and 
vdsm are in line with 15 seconds. But up to 3.3, vdsm is pooling the 
data every 5 seconds and backend is collecting data every 15 seconds. So 
2 in 3 vdsm poolings are droped. Since you're handling total bytes, this 
might not be a big issue.



* The precision of traffic measurement on a NIC is 0.1% of the
interface's speed over each PERIOD_TIME interval. For example, on a
1Gbps vNIC, when PERIOD_TIME = 15s, data will only be measured in 15Mb
(~2MB) quanta. Specifically what this means is, that in this example,
any traffic smaller than 2MB over a 15-second period would be negligible
and wouldn't be recorded.


Looking to the code, if "overhead" is bigger than "PERIOD_TIME", 
cumulative data for a given period will never be accurate. Anyway the 
script will fall in exception when that is the case (negative value for 
time.sleep()). The mentioned timestamp reported by vdsm could drop the 
need for the "overhead" calculation.

Actually vdsm is not reporting rx/tx bytes. They are "tx/rx rate". So, 
we're only able to see the average consumption for the time between 
pooling periods.

Forget the last sentence. It's a big issue since the data is not

Just waiting may not be enough: I'd love to understand what are the
metrics you'd like to use for billing.

I mentioned cummulative values of network, storage, and cpu per VM. Can
you consider anything else? The latter two are begging for an RFE to be
open, as well as the report-centric RFE requested by Shirly.

It's not exact description of the situation.

1) both nodes up => everything is working properly
2) second node power off
3) first node still have interfaces up (ovirtmgmt -> ens1f0 just without
link detected) => first node is switched into Non-Operational mode
(there should be at least some switch if I require link detected)
4) ping is working correctly over ovirtmgmt (checked via tcpdump)
between remaining node and hosted engine running on that node

I switch back to the problematic situation and ensure I'm not saying
misleading information (ens1f0 is network interface for ovirtmgmt):
ovirtmgmt: flags=4163  mtu 9000
ens1f0: flags=4099  mtu 9000
# ethtool ens1f0

Re: [ovirt-users] Billing solution

[Nikos Zaharioudakis]

Hi Dan (et all),

you know that the customers are always unsatisfied:-(

The first important stuff would be to have in place the metrics of
consumption of the
resources some hoster "sell" to a customer. So usage metrics on
CPU / RAM /  DISK / Network (over provisioned or not is another story)
There is an aspect on actual usage versus provisioned usage.
{vm provisioned 10 GB of RAM bus os+app uses just 5 GB of them etc)
But let's keep it simple.

Should we have the usage reference then a GUI that the can define
the cost plans, would be ideal. A way to query if possible that
database, would ease existing ERPs and invoicing software to
produce / send invoices. This is for mostly post paid use cases.

For prepaid situations, there must be some regular accounting that
will stop the service through our current API. It sounds a bit scaring to
actually shutdown the provisioned vm. So at least on first step stop the
networking 
I guess that the base is to create a separate database that will keep the
consumed metrics, so that customers could actually use it to
enforce some business logic. (as explained above).
Should there be a minimal gui that could a small hoster create
his owns plans and perhaps issue some "invoice" would be ideal.
Since there are a number of open source billing systems out there,
perhaps the integration is not that complicated. A second thought would
be to extend the data ware house gui to create the "invoice" outputs
as most of the usage info is there.
I know that ovirt is supposed to be a virtualization solution and not
a full monty billing system.

Thanks for reading so far.

I had a similar problem with a fresh install of oVirt 3.5.0 on RHEL 6.6 bare
metal.  I installed the Engine, then DWH and Reports on the same host.

Oddly, reports for Hosts worked, but reports for for Virtual Machines did not
collect data (for example, report BR10C = Resource Usage of Virtual Machine
--- by Hour of Day).

I looked at logs DHW, vdsm, engine, etc logs, and I did not see any errors
relating to database connectivity, pollers not collecting data, etc.  The
service ovirt-engine-dwhd was running.

So, yesterday, I made the assumption that perhaps there was a problem with the
installer and re-ran "engine-setup".  This morning, I checked the report
BR10C, and the graphs for "CPU Usage by Hour of Day", "Memory Usage by Hour of
Day" now have bar graphs (they work!).

However, the "Top Five Busiest Disks Usage by Hour of Day" and "Top Three
Businest Network Interfaces Usage" report "No Data Available".  The VM does
have the oVirt 3.5 guest software installed.

How do I troubleshoot the "No Data Available" for 'Disk Usage' and 'Network
Interfaces'?

Re: [ovirt-users] Live Merge Functionality disabled on CentOS 6.6 Node and oVirt 3.5.0

[Bob Doolittle]

Are there any bugs related to the changes in question that we can track
so we know when the changes are reflected in our distros of interest?

Thanks,
Bob

Thanks!

Would you know how one could track to see if there is a plan for e,g.
Fedora 20 to include that version at some point? I suspect every distro
is different. F20 at this point includes 1.1.3. I'd like to know if I'll
have to upgrade to Fedora 21 in order to get this functionality, as this
will require some planning on my part.

Thanks again,
Bob

[ovirt-users] Upgrade to Ovirt 3.5.0 Authentication Fails to IPA

[Ondra Machacek]

Hi,

just tried it too.
I was not successfull to reproduce, but the problem is that
the domain part of LDAPSecurityAuthentication is uppercase
as Cameron wrote.

In 3.4 it is OK when it's upper case - everything works OK,
but in 3.5 it's not.

I checked differences and something like this would be enough, Yair?

One of the migrations took about 1 minute and the progress bar was never
updated.

did you have the browser with webadmin focused? It lowers the update frequency 
when you focus some other window.
Also, could you please provide VDSM logs from such migration?
thanx,
Tomas

Sorry if I get off topic but it is related. Why is the migration bar on 
the webUI in the vm list ??


I think that a more appropriate site would be the task tab. Migration is 
a task (not all time present) and differs of metrics as 
cpu/memory/network. Also the vm list is "over populated" with items and 
is hard to visualize in small screens.

[ovirt-users] Hosted-Engine Resource Upgrade Method

[Steve Atkinson]

I was wondering what the recommended method is for adding RAM/CPUs etc. to
the VM that runs the hosted-engine. If I attempt this from the manager, the
response is "Cannot Edit: This VM is not managed by the engine" and I don't
readily see a way to make changes to the VMs config from outside of the
engine. vdsClient does not show that VM as running either.

Thanks

[ovirt-users] Simple way to activate live merge in FC20 cluster

[Markus Stockhausen]

Hi Bob,

if your are on a cluster with FC20 hypervisor nodes wthout virt-preview 
(like we run it with qemu 1.6.2) the simplest way to get live merge features 
should be - beware NOT FULLY TESTED!

1) choose a single host (we only need a single one if we think about the 
required setup)
2) Install libvirt from virt-preview repos. DON'T UPDATE QEMU AS YOU BREAK LIVE 
MIGRATION!
3) migrate VMs you want to live merge to the host
4) do the live merge
5) migrate VMs back to original host

A quick test revealed:

# systemctl stop vdsmd
# systemctl stop libvirtd
# cd /etc/yum.repos.d
# wget http:/wget 
http://fedorapeople.org/groups/virt/virt-preview/fedora-virt-preview.repo
# yum update libvirt
...
# systemctl start libvirtd
# systemctl start vdsmd
# 
# vdsClient -s 0 getVdsCaps | grep -i merge
---> liveMerge = 'true'

Best regards.

Markus

Thanks!

Would you know how one could track to see if there is a plan for e,g.
Fedora 20 to include that version at some point? I suspect every distro
is different. F20 at this point includes 1.1.3. I'd like to know if I'll
have to upgrade to Fedora 21 in order to get this functionality, as this
will require some planning on my part.

Thanks again,
Bob

Re: [ovirt-users] Simple way to activate live merge in FC20 cluster

[Bob Doolittle]

Thanks Markus, but I have a single, self-hosted node, so cannot migrate VMs.

Is it your assumption that F20 will never be updated with libvirt 1.2.9?

If that's the case, my best course (in a month or so when F21 is
released) is probably to export all my VMs, install F21,
reinstall/reconfigure oVirt, import the old Export Domain, and then
import my VMs again.

Re: [ovirt-users] Simple way to activate live merge in FC20 cluster

[Markus Stockhausen]

Hi Bob,

looking at http://koji.fedoraproject.org/koji/packageinfo?packageID=91 
I think FC20 will stay at 1.1.3. History shows:

2013/12/14: official 1.1 build libvirt-1.1.3.2-1.fc20 
2013/12/17: FC20 release
2014/01/21: first 1.2 build libvirt-1.2.1-1.fc21
2014/11/20: as of today still no 1.2 build for FC20

Regarding the fact that qemu 1.6.2 is already 11 months old and did
not see many patches in FC20 jumping onto the FC21 bandwagon
might be a reasonable solution. So a lot of ways to accomplish your goal:

- Stay with what you have: No live merge
- Take libvirtd from virt-preview
- Take everything from virt-preview
- Wait for FC21
- Wait for Centos 21

Still a long way to go to get all the beloved features out of the box.

Markus

Re: [ovirt-users] Migration Progress Bar UI question, was Migration Progress Bar not updating

[Einav Cohen]

interesting suggestion. this will also allow tracking 
progress of tasks on multiple business entity types if / 
once supported) all at once. 
Moreover, if we will have more than one task running on 
a single VM in parallel (e.g. Host migration and Snapshot 
creation - not sure if possible today, it is just an 
example for clarification), it would be nice to display 
progress per task, rather than somehow "squeeze in" all 
of this information within the vm list somehow. 

However: I think that having this information available 
*only* in the Tasks pane (i.e. instead of within the vm list) 
is problematic at the moment, since if we have 100 migrations 
happening in parallel, tracking down the migration progress 
for a particular VM that I am interested in may be difficult. 

[this, of course, can be resolved by improving the current 
tasks-pane to allow filtering, for example]

another reason to keep this data in the vm list is the 
fact that it gives a very clear graphical indication that 
this VM is currently "going through some critical process", 
so the user can make a more educated work-flow decision 
quicker. 

I agree with your comment on the already-overloaded VMs 
grid real-estate. Note that this particular issue may be 
resolved more generically in the context of [1]. 

so to summarize: I think that the state today is reasonable, 
but can be greatly improved. I assume it will be somewhat 
improved once [1] is addressed. 

proposal for further improvement:

- have the tasks progress information available twice:

  a. [detailed information] in a Tasks context. This can be 
in either one of the following, preferably both: 

 * a global Tasks context, i.e. the Tasks bottom pane. 

 * a "local" Tasks context, i.e. only for the VM, e.g.

Re: [ovirt-users] Migrate Ovirt to/from RHEV

[John Gardeniers]

Thanks Dan,

If that's the case it would be an extremely time-consuming and painful 
process, even to the point where it may not even be viable. :-(


It's increasingly looking to me like a deliberate decision has been 
taken to make it as difficult as possible to migrate VMs away from 
Ovirt/RHEV. It's the only virtualisation system I've encountered that 
doesn't have a real export system (export domains don't cut it).

John

Re: [ovirt-users] Migrate Ovirt to/from RHEV

[Dan Yasny]

Not going to argue with that, it's rather pointless, but:
http://www.ovirt.org/OVirt_3.5_Release_Notes#Import_Storage_Domain

Now this feature only needs to make it into RHEV.

My suggestion is as safe as it gets, in fact I migrated a large setup from
2.2 to 3.4 this summer with no problems

The motivation for the semicolons was to eliminate the (albeit remote)
chance of of this bridge name colliding with a previously-defined
network. It was introduced two years ago http://gerrit.ovirt.org/9562
and it is a bit two entrenched by now. Modifying it to another string,
while it is used by multiple VM in a distributed cluster of host is a
painful hassle.

It would be much more advisable for puppet to support all device names
acceptable by Linux (anything but ':. \t\0', without adding its own
limitations. I have a vague memory that Foreman encountered the same
problem, and fixed it.

Regards,
Dan.

Hello,
following the flow, as I have now an all-in-one environment based on F20
and oVirt 3.5. As it is both my engine and my hypervisor, I should be in
the best situation
live merge is supposed to be supported on file based storage, that should
match what I have (local on Host).

In fact, installing oVirt AIO on F20 automatically gives the virt-preview
repo through the ovirt-3.5-dependencies.repo file and I see:

[root@tekkaman qemu]# rpm -q libvirt
libvirt-1.2.9.1-1.fc20.x86_64

[root@tekkaman qemu]# vdsClient -s 0 getVdsCaps | grep -i merge
liveMerge = 'true'

[root@tekkaman qemu]# rpm -q qemu
qemu-1.6.2-10.fc20.x86_64

Created a CentOS 7 x86_64 VM with a VirtIO-SCSI disk and after install I
powered off and run it normally.
Then I took a snapshot (while VM powered on) and then ran a yum update.
At the end I reboot the VM with the new kernel installed and tried to
delete the snapshot and the task indeed started:
Snapshot 'test per live merge' deletion for VM 'c7' was initiated by admin.

but about a minute later I got error:
Failed to delete snapshot 'test per live merge' for VM 'c7'.

here below relevant parts in log files.
What did I miss in the workflow?

BTW: both during the live snapshot and during the live merge I got
disconnected both from spice console and from an ssh session open into VM
(I could reconnect on both): is this expected? I hope not so..

[ovirt-users] Jumbo Frames

[Phil Daws]

Hello:

am really enjoying oVirt but have now hit an issue with iSCSI.  As there is 
only one NIC in the host I have had to enable an MTU of 9000 on ovirtmgmt.  
Then have vNIC profiles on that interface which are using a custom hook for 
Openvswitch.  I have created a specific vLAN for iSCSI traffic and on the 
initiator and targets have set their respective interface MTUs to be 9000.  
When I connect to a LUN it is timing out straight away with a 1011 error.  If I 
drop the MTU back to 1500 all works okay.  This is all fine on my other KVM, 
non-oVirt, system so am wondering if I have missed a step ?

Thanks, Phil

OK, I reply to myself
The error above is explanatory...
I didn't notice that only the libvirt part is included in the
ovirt-3.5-fedora-virt-preview repo:

"
[ovirt-3.5-fedora-virt-preview]
name=Virtualization packages from Rawhide built for latest Fedora
baseurl=
http://fedorapeople.org/groups/virt/virt-preview/fedora-$releasever/$basearch
enabled=1
skip_if_unavailable=1
gpgcheck=0
includepkgs=libvirt*
"

SO I think I need qemu-2.1.2-6.fc20.x86_64.rpm and probably other packages
as provided by virt-preview.
What could be the safest way to include further qemu packages?
How stable is qemu 2.1.2 at this time?

Thanks,
Gianluca

[ovirt-users] 答复: 答复: How to Use VLAN?

[Xie, Chao]

Hi, Lior
Thanks for replying. Yesterday I tested  VLAN successfully  in the 
normal 3.5 environment. As the release Note, 
(http://www.ovirt.org/OVirt_3.5_Release_Notes), Hosted Engine 3.5 supports the 
new function of VLAN。 Is it meaning the "rhevm" logical network use "VLAN" ? If 
 I am right, can you help to teach me how to use it? (I think it must be 
creating a VLAN manually before deploy hosted engine, then we should choose the 
vlan when deploying?)

Hello Xie,

This is what leads me to believe that your DHCP server (which is in charge of 
allocating IP addresses) only receives non-tagged traffic. Is it possible you 
need to configure other ports to pass the VLAN-tagged traffic?

Re: [ovirt-users] Jumbo Frames

[Dan Yasny]

Why do you use OVS at all? If you have VLANs, all you need is to tag the
mgmt traffic, and create a VM traffic VLAN with a different MTU. The bridge
and underlying NICs will have MTU=9000 and the VM bridge will have MTU=1500

Re: [ovirt-users] Simple way to activate live merge in FC20 cluster

[Markus Stockhausen]

Wow. Very quick test. Thanks for sharing the results. I will have a look what 
qemu 1.6.2 might need.

Regarding stability of qemu 2.1.2: You should scan the qemu stable mailing list 
if some severe fixes have been  posted after the release. If you feel 
comfortable take qemu from  the preview repos too.

Just a simple yum update.

Remark: With the advent  of FC21 virt-preview for FC20 might see  no further  
fixes.

OK, I reply to myself
The error above is explanatory...
I didn't notice that only the libvirt part is included in the 
ovirt-3.5-fedora-virt-preview repo:

"
[ovirt-3.5-fedora-virt-preview]
name=Virtualization packages from Rawhide built for latest Fedora
baseurl=http://fedorapeople.org/groups/virt/virt-preview/fedora-$releasever/$basearch

"

SO I think I need qemu-2.1.2-6.fc20.x86_64.rpm and probably other packages as 
provided by virt-preview.
What could be the safest way to include further qemu packages?
How stable is qemu 2.1.2 at this time?

Thanks,
Gianluca

Hey,

could you please explain the exact flow you tried?

What branch did you use to build your iso?

And for SELinux denials: Catch /var/log/audit/audit.log and create new rules 
using
audit2allow.
