[ovirt-users] VM with attached host USB device failed to run

[Дровалев Роман]

Hello,

I connected a USB to the VM, writes this error: VM Win2012 is down with
error. Exit message: local variable 'device' referenced before assignment.

I found this bug - https://bugzilla.redhat.com/show_bug.cgi?id=1261075

Does anyone have a working USB forwarding in a virtual machine? If
"YES", how did you solve this problem?

If this problem is not solved, unfortunately, the ovirt will have to
completely abandon. ((

Fernando,

Which ovirt version are you running? Please share the logs so I could
check what caused the hosts to become unresponsive.

Thanks,

Re: [ovirt-users] oVirt and FreeNAS

Hi,

1. Is it in production?


Not really, just for testing purposes to provide some kind of shared 
storage for OVirt. I like FreeNAS, it's a very nice system but for 
production we use a setup with distributed/mirrored storage that 
tolerates the loss of a storage device or even a complete server room 
(Datacore on FC infrastructure). I haven't tested OVirt with Datacore 
yet, maybe I'll have time and hardware for this next year.


2. Can you share details about your FreeNAS installation - hardware 
used, RAM installed, Type of Disks - SATA, SAS, SSD, network cards 
used? Do you have SSD for ZIL/L2ARC? 3. The size of your data

domain? Number of virtual machines? .


Nothing spectacular: HP microservers or white boxes with 16-32 GB ECC 
Ram and 4-6 Sata disks (500GB - 2TB), 2x1 Gbit/s (Intel) for iSCSI. The 
network is the limiting factor, no extra SSDs used/needed.

The used capacity should be consistent on all nodes - I see you have a
discrepancy with the data volume brick. What does "gluster vol heal data

Can you provide the glustershd logs?

https://bugzilla.redhat.com/show_bug.cgi?id=1450152 - was fixed to use
chronyd instead of ntpd in gdeploy.

If you're still seeing the issue, can you re-open the bug with version

Re: [ovirt-users] oVirt and FreeNAS

Using it here on production since the last 3 years, no problems so far.
iscsi and nfs shares.

2 servers on supermicro x10srl with xeon E5-2603 v3 @ 1.60GHz , 128Gb ram
each, 2 intel ssd for zil 2 ssd for l2arc, 16 sata disks. using ibm
1015hba's flashed as 'it' mode.
I had to tune it a lot to get best performance both on the nodes and on the
storage side, sysctl. no rule of tumb. also many changes at hand to get
full multipath, failover, queue depth, reqs, io schedulers, etc.
network cards, all Intel.

Re: [ovirt-users] Communication Problems between Engine and Hosts

[FERNANDO FREDIANI]

Hello Piotr. Thanks for your reply

I was running version 4.1.1, but since that day I have upgraded to 4.1.5 
(the Engine because the hosts remain on 4.1.1). I am not sure the logs 
still exists (how long they are kept normally).


Just to clarify the hosts didn't become unresponsive, but the 
communication between the Engine and the Hosts in question (each in a 
different Datacenter was interrupted - but locally the hosts were fine 
and accessible). What was strange was that since the Hosts could not 
talk to the Engine they seem to have got 'confused' and started several 
VM live migrations which was not expected. As a note I don't have any 
Fencing policy enabled.


Regards
Fernando

Hello.

Yesterday I had a pretty strange problem in one of our architectures. My
oVirt which runs in one Datacenter and controls Nodes locally and also
remotelly lost communication with the remote Nodes in another Datacenter.
To this point nothing wrong as the Nodes can continue working as expected
and running their Virtual Machines each without dependency of the oVirt
Engine.

What happened at some point is that when the communication between Engine
and Hosts came back Hosts got confused and initiated a Live Migration of ALL
VMs from one of the other. I had also to restart vdsmd agent on all Hosts in
order to get sanity my environment.
What adds up even more strangeness to this scenario is that one of the Hosts
affected doesn't belong to the same Cluster as the others and had to have
the vdsmd restarted.

I understand the Hosts can survive without the Engine online with reduced
possibilities but can communicated between them, but without affecting the
VMs or even needing to do what happened in this scenario.

Am I wrong on any of the assumptions ?

[ovirt-users] oVirt Node with bcache

[FERNANDO FREDIANI]

Hello

I just wanted to share a scenario with you and perhaps exchange more 
information with other people that may also have a similar scenario.


For a couple of months I have been running a oVirt Node (CentOS 7.3 
Minimal) with bcache (https://bcache.evilpiepirate.org/) for caching a 
SSD with HDD disks. The setup is simple and was made for a prof of 
concept and since them has been working better than expected.
This is a standalone host with 4 disks being: 1 for Operating System, 2 
x 2TB 7200 RPM in software RAID 1 and 1 x PCI-E NVMe 400GB SSD which 
plays the caching device for both reads and writes. The VM storage 
folder is mounted as a ext4 partition on the logical device created by 
bcache (/dev/bcache0). All this is transparent to oVirt as all it sees 
is a /folder to put the VMs.


We monitor the IOPS on all block devices individually and see the 
behavior exactly as expected: random writes are all done on the SSD 
first and them streamed sequentially to the mechanical drives with 
pretty impressive performance. Also in the beginning while the total 
amount of data was less than 400GB ALL read used to come from the 
caching device and therefore didn't use IOPS from the mechanical drives 
leaving it free to do basically writes. Finally at sequential IOPS (as 
described by bcache) are intelligently passed directly to the mechanical 
drives (but they are not much).


Although bcache is present on kernel 3.10 I had to use kernel-ml 4.12 
(from Elrepo) and I had also to compile the bcache-tools as I could not 
find it available in any repository.

[ovirt-users] Ldap authentification filtering with custom attribute

[Jean-mathieu CHANTREIN]

Hello. 

Here is a way to filtering a group of ldap user by one of custom attribute and 
not by groups ? By example, I tryed (without success) to put this entry in 
/etc/ovirt-engine/extensions.d/my-ldap-authz.properties : 

search.simple-resolve-groups-memberOf.search-request.filter = 
&(myCustomAttribute=nameOfAttributeToFilter) 

And if it's possible, can I have filtering with more than one attribute (i.e.: 
each attribute will be discriminate like a group) ? 

Thanks for your help.

[ovirt-users] Ovirt Network NAT

[Simms, Peter]

Hi all,

I am trying to setup a NAT network for my networks so my VMs can just use NAT 
instead of getting their own IP.  I seem to be struggling on how to do this, I 
found the below link, however can't seem to get this working.  Is this still 
the best way to achieve this or what is the best way to achieve a NAT network 
that my VM's can use?

http://www.ovirt.org/develop/developer-guide/vdsm/hook/network-nat/

Any help would be appreciated, thank you

Can you check if you have vdsm-gluster rpm installed on the hosts?

Nice!
It'd be great if you could write an ovirt.org blog about setting it up and
how it worked for you in.
Have you considered using dm-cache?
Y.

Re: [ovirt-users] VM Portal looking for translators

[Nicolás]

Hi,

Why do I see a red lock on the translation page claiming "This 
project-version is readonly. It cannot be edited"? Do I have to be 
granted access specifically on the language site to translate?


(Not sure if related: Requested access to some language groups like 
described in [3], but it's still pending).


Thanks.

Nicolás
