OK, that makes sense. I think this is a bug in the server then. If the
users are not oVirt users we should just not report them, or maybe
report just the user name and domain, if available. But returning 404
and failing in that case isn't correct, in my opinion. I have opened the
following bug to track this issue:

  Don't fail with 404 if session user doesn't exist in the database

Re: [ovirt-users] Python-SDK4: How to list VM user sessions?

2017-04-10 Thread Giorgio Biacchi

Hi,
I'm taking over Giulio because he's not at work now. I'm starting to understand 
what's happening because we have not that users (and many others) in the users 
tab in the admin portal.


We have heavily modified the paradigm of ovirt, VM are bound to thin clients and 
not to users, this because we want to reproduce a lab/classroom environment and 
we don't use the user portal. We wrote an alternative administration portal 
where we define classrooms, thin clients and associations between clients and VMs.


Windows VMs are joined to a AD domain and linux VMs are joined to IPA, home dirs 
are remotely mounted upon user login.


So there's no need to have all that users (over 31000) in the admin portal 
because they have no permission on any VM, they can login from any client to the 
VM bound to that client.


In the admin portal, if I go to a VM with a logged in user in the "Guest info" 
tab I can see which user is logged in because, I think, the guest agents are 
aware of the logged in username, but there's no "user object" in the engine when 
I try to get that information via API.


Thanks for your time and patience..

Regards,
Giorgio

It's quite strange I can perform almost every other operation (e.g.
getting other VM parameters, running methods, etc.)




Finally, please run your script with the 'debug=True' option in the
connection, and with a log file, like here:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/list_vms.py#L20-L37



Then share that log file so that we can check what the server is
returning exactly. Make sure to remove your password from that log file
before sharing it.


Find attached produced log (passwords purged).

BTW: VM is a Fedora 24, with guest agents correctly installed (I can see
user sessions in admin portal and in postgresql DB).

Thanks,
Giulio

For best multimedia performance a resonable graphics card and cpu in
your thin client is needed and up-to-date remote viewer version.

I used thin clients from IGEL in many setups. If you want good
multimedia performance (watching full HD videos in your vm) you need
the UD5. IGEL is a good solution when it comes to managing thin clients
as they have a great management server for it. The downside is that
IGEL thin clients aren't really cheap and remote viewer comes in a
quite old version.

One of my customers uses Intel NUC devices with Fedora on it (PXE boot)
and has a much better performance as with IGEL UD5, but to be fair he
compared it with the 5 year old UD5 model. This is mainly because of
the newer processors in Intel NUC and new virt-viewer of Fedora.

Hope this helps.

René

the strange thing here is that the sosreport Eric provided showed no
selinux denials in ausearch -m avc output.
If it's selinux, it's tracked here:

Re: [ovirt-users] iSCSI storage domain and multipath when adding node

2017-04-10 Thread Ondrej Svoboda
Yes, this is what struck me about your situation. Will you be able to find
relevant logs regarding multipath configuration, in which we would see when
(or even why) the third connection was created on the first node, and only
one connection on the second?

[ovirt-users] EMC Unity 300

2017-04-10 Thread Colin Coe
Hi all

We are contemplating moving away from our current iSCSI SAN to Dell/EMC
 Unity 300.

I've seen one thread where the 300F is problematic and no resolution is
posted.

Is anyone else using tis with RHEV/oVirt?  Any war stories?

Ok, this evening I'm going to open a bugzilla for that.
Please keep in mind that on the already configured node (where before node
addition there were two connections in place with multipath), actually the
node addition generates a third connection, added to the existing two,
using "default" as iSCSI interface (clearly seen if I run "iscsiadm -m
session -P1")

Gianluca,

I can see that the workaround you describe here (to complete multipath
configuration in CLI) fixes an inconsistency in observed iSCSI sessions. I
think it is a shortcoming in oVirt that you had to resort to manual
configuration. Could you file a bug about this? Ideally, following the bug
template presented to you by Bugzilla, i.e. "Expected: two iSCSI sessions",
"Got: one the first node ... one the second node".

Edy, Martin, do you think you could help out here?

Is it node setup? Today i tried to upgrade my one node cluster, after that
VM's fail to start, it turns out that selinux prevents virtlogd to start.

ausearch -c 'virtlogd' --raw | audit2allow -M my-virtlogd

fixed things for me, YMMV.

I would suggest to read our Installation Guide at

I think it will help you getting a proper setup in place starting from a
clean minimal system.
Once the system is up, I would suggest to read also our Administration

Thanks, that helps. What the engine isn't finding is the user, not the
virtual machine. Can you provide more information about that user? I
mean, take the virtual machine and find via the GUI which user is using
it. Then go to https://.../ovirt-engine/api/users and find that user.
Share the definition of that user that you get there, if possible.

 Giulio, you should never get a 404 error from that URL, unless the
 virtual doesn't exist or isn't visible for you. What user name are you

Hi Everyone,

  Just an update, I installed a new Ubuntu guest VM and it was doing 
the same thing regarding the network going down, then I disabled IPv6 
and it's been fine for the past 10-15 minutes.  So the issue seems to be 
IPv6 related, and I don't need IPv6 so I can just turn it off.  The eth1 
NIC disappearing is still worrisome though.

Hello Charles,

First, can you give us more information regarding the duplicated
IPv6 addresses? Since you are going to reinstall the hosted
engine, could you make sure that NetworkManager is disabled
before adding the second vNIC (and perhaps even disable IPv6 and
reboot as well, so we have a solid base and see what makes the
difference)?

I disabled NetworkManager on the hosts (systemctl disable 
NetworkManager ; service NetworkManager stop) before doing the oVirt 
setup and rebooted to make sure that it didn't come back up.  Or are 
you referring to on the hosted engine VM?  I just removed and re-added 
the eth1 NIC in the hosted engine, and this is what showed up in dmesg:

so, could you file a bug against VDSM networking and attach

No problem, find attached a snippet of server.log.

Hi,
I'm trying to obtain a list of users connected to a VM, using python SDK
v4.
Here's what I'm doing:

vm = vms_service.list(search="name=vmname")[0]
vm_service = vms_service.vm_service(vm.id)
sessions = vm_service.sessions_service().list()

But "sessions" is None.

Same result using:

s = connection.follow_link(vm.sessions)

"s" is None.

I tried also using curl, and if I connect to:

https://my.ovirt.host/ovirt-engine/api/v4/vms//sessions

I get a beautiful 404.

Also using v3 of python SDK I obtain the same behaviour.

So I suspect that retrieving user sessions via API is not implemented,
is it? If not, what I'm doing wrong?

I'm using RHV 4.0.6.3-0.1.el7ev

Thanks in advance,
Giulio



Giulio, you should never get a 404 error from that URL, unless the
virtual doesn't exist or isn't visible for you. What user name are you
to create the SDK connection? An administrator or a regular user?



I tried with a regular domain user (with superuser role assigned) and
admin@internal, with same result.


Also, please check the /var/log/ovirt-engine/server.log and
/var/log/ovirt-engine/engine.log when you send that request. Do you see
there something relevant?


server.log reports:

2017-03-31 10:03:11,346 ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n]
(default task-33) RESTEASY002010: Failed to execute:
javax.ws.rs.WebApplicationException: HTTP 404 Not Found

(no surprise here, same message obtained by curl).

engine.log is full of:

ERROR [org.ovirt.engine.core.aaa.filters.SsoRestApiAuthFilter] (default
task-7) [] Cannot authenticate using authentication Headers:
invalid_grant: The provided authorization grant for the auth code has
expired

(indipendently of my request)

It's quite strange I can perform almost every other operation (e.g.
getting other VM parameters, running methods, etc.)




Finally, please run your script with the 'debug=True' option in the
connection, and with a log file, like here:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/list_vms.py#L20-L37


Then share that log file so that we can check what the server is
returning exactly. Make sure to remove your password from that log file
before sharing it.


Find attached produced log (passwords purged).

BTW: VM is a Fedora 24, with guest agents correctly installed (I can see
user sessions in admin portal and in postgresql DB).

Thanks,
Giulio

When you change something in the HE Vm using the web ui, it has to be saved
also on the OVF_STORE to make it permanent for further reboot.
Martin can you please elaborate here?

As far as I know there is no way to "force" moving the host to
maintenance, at least not with the API. I'd suggest that you check the
logs (/var/log/ovirt-engine/engine.log and
/var/log/ovirt-engine/server.log) and see if there is some relevant
message when you try that. If so, share those messages.

Re: [ovirt-users] More 4.1 Networking Questions

2017-04-10 Thread Ondrej Svoboda
Hello Charles,

First, can you give us more information regarding the duplicated IPv6
addresses? Since you are going to reinstall the hosted engine, could you
make sure that NetworkManager is disabled before adding the second vNIC
(and perhaps even disable IPv6 and reboot as well, so we have a solid base
and see what makes the difference)?

What kind of documentation did you follow to install the hosted engine? Was
it this page? https://www.ovirt.org/documentation/how-to/hosted-engine/ If
so, could you file a bug against VDSM networking and attach
/var/log/vdsm/vdsm.log and supervdsm.log, and make sure they include the
time period from adding the second vNIC to rebooting?

Second, even the vNIC going missing after reboot looks like a bug to me.
Even though eth1 does not exist in the VM, can you see it defined for the
VM in the engine web GUI?

The steps you took to install the hosted engine with regards to networking
look good to me, but I believe Sandro (CC'ed) would be able to give more
advice.

Sandro, since we want to configure bonding, would you recommend to install
the engine physically first, move it to a VM, according to the following
method, and only then reconfigure networking?
https://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Metal_to_an_EL-Based_Self-Hosted_Environment/

Thank you,
Ondra

Re: [ovirt-users] engine upgrade 4.1.0 => 4.1.1, no more engine console available

2017-04-10 Thread Rafał Wojciechowski

hi,

I have similiar issue(I also started my mailthread) after upgrade 4.0 to 4.1

Version 4.1.1.8-1.el7.centos (before it was some 4.1.0.x or similiar - 
update not fixed it)


to run VM I have to set in Console tab Headless mode - without it I got 
libvirtd segfault(logs attached in my mailthread).


So I am able to run VMs only without Console - do you also have to set 
headless before run VM?


I noticed that libvirt-daemon was also upgraded to 2.0 version during 
ovirt upgrade - I dont think that 4.1 was not testes due to such 
libvirtd upgrade... but maybe?

Rafal Wojciechowski

[ovirt-users] More 4.1 Networking Questions

2017-04-10 Thread Charles Tassell

Hi Everyone,

  Okay, I'm again having problems with getting basic networking setup 
with oVirt 4.1  Here is my situation.  I have two servers I want to use 
to create an oVirt cluster, with two different networks.  My "public" 
network is a 1G link on device em1 connected to my Internet feed, and my 
"storage" network is a 10G link connected on device p5p1 to my file 
server.  Since I need to connect to my storage network in order to do 
the install, I selected p5p1 has the ovirtmgmt interface when installing 
the hosted engine.  That worked fine, I got everything installed, so I 
used some ssh-proxy magic to connect to the web console and completed 
the install (setup a Storage domain and create a new network vmNet for 
VM networking and added em1 to it.)


  The problem was that when I added a second network device to the 
HostedEngine VM (so that I can connect to it from my public network) it 
would intermittently go down.  I did some digging and found some IPV6 
errors in the dmesg (IPv6: eth1: IPv6 duplicate address 
2001:410:e000:902:21a:4aff:fe16:151 detected!) so I disabled IPv6 on 
both eth0 and eth1 in the HostedEngine and rebooted it.  The problem is 
that when I restarted the VM, the eth1 device was missing.


  So, my question is: Can I add a second NIC to the HostedEngine VM and 
make it stick, or will it be deleted whenever the engine VM is 
restarted?  Is there a better way to do what I'm trying to do, ie, 
should I setup ovirtmgmt on the public em1 interface, and then create 
the "storage" network after the fact for connecting to the datastores 
and such.  Is that even possible, or required?  I was thinking that it 
would be better for migrations and other management functions to happen 
on the faster 10G network, but if the HostedEngine doesn't need to be 
able to connect to the storage network maybe it's not worth the effort?


  Eventually I want to setup LACP on the storage network, but I had to 
wipe the servers and reinstall from scratch the last time I tried to set 
that up.  I was thinking that it was because I setup the bonding before 
installing oVirt, so I didn't do that this time.


  Here are my /etc/sysconfig/network-scripts/ifcfg-* files in case I 
did something wrong there (I'm more familiar with Debian/Ubuntu network 
setup than CentOS)


ifcfg-eth0: (ovirtmgmt aka storage)
