Re: [ovirt-users] Storage Domain Not Found After upgrade from 3.3.2 to 3.4

[Gadi Ickowicz]

Hi Paul,

Looking at what you sent, it seems a bit strange - another domain was added to 
the data-center according to the logs you sent in the other mail (the ones 
after the upgrade). 
If you could send the engine logs for for the same time period and the engine 
upgrade log, there may be some information there, but currently the log you 
sent just starts from the fact that there is a missing storage domain, and it 
is already listed in the storage pool's metadata.

In any case, it is (somewhat) good to hear that reverting to 3.3.2 at least 
returned the system to a sane state.

Thanks,
Gadi Ickowicz

Hi Gadi,

Thanks for the response.

I've only just had chance to restore that node back, which completed 
fine and the DC and it's storage domains activated ok.  So the 
ovirt-node is now fully functional again on the 3.3.2 version; the 
ovirt-engine server remains untouched on 3.4 and is working fine.

I collected the requested info, but it doesn't list the ID you pulled 
out of the vdsm.log:

[root@ovirt-node ~]# vdsClient -s 0 getStorageDomainsList
e637bb04-a8b7-4c77-809c-d58051494c52

0a897f2e-1b01-4577-9f91-cd136ef4a978

I tried anyway to list against that ID and I get the storage domain 
doesn't exist error, but maybe that's because it really doesn't exist!?
[root@ovirt-node ~]# vdsClient -s 0 getStorageDomainInfo 
9a4a80a1-5377-4a94-ade3-e58183e916ae
Storage domain does not exist: ('9a4a80a1-5377-4a94-ade3-e58183e916ae',)

I grabbed the info against all the Storage Domain IDs from the list 
without issue:
[root@ovirt-node ~]#

I checked the logfile for today and since the restore there are no 
errors about this storage domain not existing:

[root@ovirt-node vdsm]# grep "04-29" vdsm.log|grep 
"StorageDomainDoesNotExist"
[root@ovirt-node vdsm]#

I also checked the IDs listed on the ovirt-engine server just on the 
off-chance, but the ID throwing the error doesn't exist on that either:

[root@ovirt-engine ~]# vdsClient -s 0 getStorageDomainsList
feb04d94-4ea8-471c-b759-3ed95943e9a3
b3c02266-2426-4285-b4dc-0acba75af530

79178b6b-8d98-45e4-93f2-3ce1d7a270a5

None of the storage domains exist on the root VG partitions, they are 
completely separate disks in separate VGs.  I did delete some Storage 
Domains on both the ovirt-engine and the ovirt-node a number of weeks 
back, but if it was due to this I would have expected the issues on both 
servers, not just one.

Have you found anything else that looks interesting in the log?

Thanks, Paul

Re: [ovirt-users] IP forwarding... Cannot access guest IP

[richard . seguin]

Dan,

I knew that something didn't quite make sense when I tried this earlier today.  
I'm glad that I set this up on my home lab, because I got it working using the 
advice that you folks provided.  Now that I know that this is a viable 
solution, I can go back and start learning this correctly, from the beginning.  
 

Thank you :)

Richard Seguin

Would you confirm that once you have set macspoof=true, libvirt's domxml
for the relevant VM has lost its  element? (virsh -r dumpxml
would verify that)

This should allow you to ping out of the Xen guest outside of the KVM
host. If it doesn't, we'd have to debug this to understand what drops
your packets.

I'm not quite sure what you mean by "promiscuous mode". What VMWare
calls promiscuous mode is not unlike oVirt's port mirroring, but I'm not
convinced that this is what you are looking for.

Dan.

[ovirt-users] Unable to make Single Sign on working on Windows 7 Guest

[Felipe Herrera Martinez]

On the case I'll be able to create an installer, what is the name of the 
Application need to be there, in order to ovirt detects that Ovirt Guest agent 
is installed?

I have created an installer adding OvirtGuestService files and the Product Name 
to be shown, a part of the command line post installs..

I have tried with "ovirt-guest-agent" and "Ovirt guest agent" Names for the 
application installed on Windows 7 guest and even both are presented on ovirt 
VM Applications tab, 
on any case LogonVDScommand appears.

There is other option to make it work now?

Thanks in advance,
   Felipe

All of the other hypervisors that I am reading about allows for promiscuous

Re: [ovirt-users] IP forwarding... Cannot access guest IP

Hi Alex,

I already did that part. 

It's strange... The xen guest can ping dom0... but nothing beyond it... yet 
dom0 can ping other addresses... and the guests...  It almost sounds like I 
have a nat going on here...

If the mac address is the issue wouldn't it be easier for him to just edit the 
VM and in custom properties set macspoof to true?

Re: [ovirt-users] Storage Domain Not Found After upgrade from 3.3.2 to 3.4

[regpm]

Hi Gadi,

Thanks for the response.

I've only just had chance to restore that node back, which completed 
fine and the DC and it's storage domains activated ok.  So the 
ovirt-node is now fully functional again on the 3.3.2 version; the 
ovirt-engine server remains untouched on 3.4 and is working fine.


I collected the requested info, but it doesn't list the ID you pulled 
out of the vdsm.log:

I checked the logfile for today and since the restore there are no 
errors about this storage domain not existing:


[root@ovirt-node vdsm]# grep "04-29" vdsm.log|grep 
"StorageDomainDoesNotExist"

[root@ovirt-node vdsm]#

I also checked the IDs listed on the ovirt-engine server just on the 
off-chance, but the ID throwing the error doesn't exist on that either:


[root@ovirt-engine ~]# vdsClient -s 0 getStorageDomainsList
feb04d94-4ea8-471c-b759-3ed95943e9a3

79178b6b-8d98-45e4-93f2-3ce1d7a270a5

None of the storage domains exist on the root VG partitions, they are 
completely separate disks in separate VGs.  I did delete some Storage 
Domains on both the ovirt-engine and the ovirt-node a number of weeks 
back, but if it was due to this I would have expected the issues on both 
servers, not just one.


Have you found anything else that looks interesting in the log?

Thanks, Paul

Hi Paul,

I am still looking into this log, but from a quick first assessment, it looks

[ovirt-users] [Events] Creating an oVirt Speaker's Bureau

[Brian Proffitt]

All:

As we work to raise awareness about oVirt at events around the world, we are 
always seeking community members who would be willing to attend events on 
behalf of oVirt to give general oVirt talks, help out with booths/stands, and 
give workshop-oriented talks. But the problem is that right now, it is not 
entirely clear where all of you are physically located.

So, to help with this, I want to take a census of anyone who is interested in 
helping with event work, to create a speakers bureau list. This information 
would be private and maintained by me so if an event that's "local" for someone 
happens, we can directly let you know about it and gauge your interest.

If you are interested in speaking at events or helping with workshops, please 
send me the following information:

Name
Email (or better contact info)
Location (City, Country)
Topics of Interest

Thanks!

Re: [ovirt-users] Live migration failing

[Dafna Ron]

I don't think that there is an inconsistency, there seem to have been a 
problem in your setup which cause an issue in migration at that time. if 
you are able to migrate it means that the issue was resolved.
It might be a bug or there might have been a problem with the network or 
storage at the same time you were trying to migrate but it's ok now.

In any case, this is what I see in the logs:

I can see that the migration was stuck:

The migration reached 79% and than there was a problem connected to the 
vm's disk (perhaps there was an intermittent issue with your network 
connection to the storage making it intermittently unavailable from the 
host?)

yes, that's what I'm suggesting. But this requires having the hook

Re: [ovirt-users] Live migration failing

[Dafna Ron]

Actually, the best way to debug this would be to look at both des and 
src vdsm logs.

is this happening on all vm's or just one of them?
was this vm launched from an iso? is that iso still available?
are there any snapshots?
what are the vdsm, libvirt and qemu versions?

Thanks.

Hi, in both cases the core issue is

ibvirtError: Unable to read from monitor: Connection reset by peer

can you share the libvirtd and qemu logs?

Hopefully we can find some more information on those logs.

If the mac address is the issue wouldn't it be easier for him to just edit the

I cannot say that I understand your setup, but if you have nested
virtuallization (such as a Xen udom) you may experience ovirt's
no-mac-spoofing rule: by default we disallow our VMs to emit traffic
that has different mac address from the one assigned by oVirt.

To avoid this, follow http://www.ovirt.org/Vdsm_Hooks#Installing_a_hook
and report if that's the issue.

Re: [ovirt-users] IP forwarding... Cannot access guest IP

[richard . seguin]

Hi Dan,

Yes I am an ovirt user.  Basically, I am running into an issue running xen 
inside of kvm.  Our scenario is that this is lab environment, and we enjoy the 
luxury of spinning up kvm instances (as opposed to installing on bare metal 
each time we need something). Our product uses Xen, and we are pretty much 
stuck with it for the time being.

I think what I am running into is a double bridge issue... Xen has a bridge, 
and so does kvm obviously.  I am able to ping dom0 (which is just the bridge 
itself) on Xen from the outside world, but I am not able to ping udom... and... 
udom doesn't have access out either.   When I was using vmware, I enabled 
promisc mode on the virtual switch, and this solution worked fine... 

If we ignore the types of technology that I am using,  and just focus on the 
networking, what would I be looking at as possibilities?  Or... a better 
question would be, does ovirt have a promiscuous flag somewhere that I can set?

Are you an oVirt user, or are you considering to migrate?

I don't quite understand your question. Could you describe your use case
again (maybe with example of your network). I'd love to understand from
where you'd like to access your guest IP.

Re: [ovirt-users] Pass through for serial port

[Daniel Helgenberger]

Hello Neil,

AFAIK there is know such thing out of the box right know. I have an
ongoing question right know concerting pretty much the same thing (pass
through of a scsi device).

I think you should have a look at the 'hostusb' vdsm hook. It will need
a little bit of rewriting of course (I have no time to do this right
know myself...)

Cheers,

[ovirt-users] Pass through for serial port

[Neil]

Hi guys,

We are running Ovirt 3.2.2 and would like to assign or allocate the
serial port of one of the processing hosts through to a guest, I'm
assuming that we'd need to disable migration to achieve this to ensure
the port mapping never changes, but how do we achieve this pass
through?

Is it possible to do this?

We have googled around for possible solutions but haven't found one yet.

Thank you.

Regards.

Neil Wilson.

It shouldn't - that is the whole point of an export domain - do be able to move

Hi, in both cases the core issue is

ibvirtError: Unable to read from monitor: Connection reset by peer

can you share the libvirtd and qemu logs?

Hopefully we can find some more information on those logs.

Re: [ovirt-users] Copying VM from one datacenter to another

[Gadi Ickowicz]

Hi,

AFAIK the way to copy a vm from one DC to another is:

1. Export vm to export domain
2. deactivate + detach export domain from source DC
3. attach and activate export domain to target dc
4. import the vm

Hello! 




De facto; I have two datacenter: 

- 1 with one host, configured with local storage, just added in the engine; 
- 1 with 3 host, 2 shared storage domain, 1 ISO and 1 Export 

For some backup reasons ( cold backup) I want to copy machines from second

Is there some documented way of doing this? 
Any hints, thoughts, similar experience?

[ovirt-users] iso-uploader with hosted-engine

[Garry Tiedemann]

Hi guys,

I built my hosted-engine with three nodes (3.4, CentOS), and built a 
Gluster ISO domain, connected it up, all good.


Until I come to engine-iso-uploader, it is present on the hosted-engine 
but not on the VMs.
And my gluster subnet is not routed. So the VM can't see it to upload 
ISOs into.


How are other people getting around this?

I can see:
1. Obvious - make the Gluster LAN routed. It wouldn't hurt, just for 
transferring a few ISOs.
2. Add a second NIC to the hosted-engine VM, so that it can see the 
gluster LAN

3. put engine-iso-uploader on one of the nodes, is that possible?

My preference is to connect hosted-engine to the Gluster LAN.

Is it possible to add another NIC to the VM, after it's built? (I don't 
want to rebuild if avoidable; I've done that enough times).
I know that the ovirt GUI isn't aware of the first NIC on the VM, so I 
haven't dared to try adding a NIC there. Is that safe?


Thanks in advance for your thoughts on this.

cheers,

*Garry

Re: [ovirt-users] [Users] Failure to connect to engine with Nagios

[Sven Kieske]

Hi,

for the record:

we have no problems
connecting nagios with
check_rhev3 (v 1.4)
using ldap user.
this is on engine 3.3.3

so maybe it's related to ipa
or to the connection
between ipa and engine, or a change
in ovirt after 3.3.3.
But I guess most likely it's
the connection.

There is one for fedora 20: https://bugzilla.redhat.com/show_bug.cgi?id=1037663
Looks like Fedora rebased sos to 3.0 also on Fedora 19, introducing the 
conflict.
Workaround on F19 is to downgrade to sos-2 and then add sos to exclude in 
/etc/yum.conf.

exclude=sos

I'll retarget bug 1037663 to 3.4.2.
