Graphics are turned upside down when install QXL in Windows
by Karli Sjöberg
Heya!
Just thought that I´d report something hilarious:)
After installing the QXL driver in Windows 7 and 2008R2, in the SPICE
HTML5 browser client, all of the graphics are turned 180 degrees. It´s
not that the entire screen is flipped either, but all of the individual
elements are. E.g. the trashcan that should be in the top right corner
is now located in the bottom right, flipped upside down with the text
"above" it and text also flipped. Opening an explorer windows still has
the location and search bar at the top, with location bar first and
search bar to the right, as it should be, but with the graphics turned
upside down, plus that the text is still printed from left to right,
but upside down. And the "favorites" pane is still located to the left
but listed from bottom the top, Windows has never looked this funny:)
A picture says a thousand words. Behold!
http://imgur.com/a/32P12
The native client displays as it should.
Just letting you know.

oVirt Nodes Monitoring
by FERNANDO FREDIANI
Hi.
How do you guys monitor your hosts with Zabbix ?
I see the oVirt Nodes have snmpd service installed and could be used for
basic things but ideally, for Zabbix is good to use its agent.
What would be the best way to install its zabbix-agent package and make
it persistent ? Add its repository to the oVirt-Node in
/etc/yum.repos.d/ and install it with yum or install using a .rpm directly ?
Thanks

Error on Node upgrade

Hello.
I'm running oVirt-Node *4.1.0--0.20170201.0+1* on my hosts and tried a
normal upgrade. It detected it has to upgrade to
*4.1.1-0.3.rc1.20170303133657.git20d3594.el7.centos* from the
ovirt-4.1-pre repository.
The upgrade finished with the following problems:
...
Running transaction
Updating :
ovirt-node-ng-image-4.1.1-0.3.rc1.20170303133657.git20d3594.el7.centos.noarch

rm: cannot remove
‘/tmp/tmp.N6JgSdFcu6/usr/share/imgbased/*image-update*.rpm’: No such

umount: /tmp/tmp.N6JgSdFcu6: not mounted
...
So it seems it was not able to do it correctly.
This is the second time it happens and I had to remove manually these
packages containing 4.1.1 version.
Tried also:
# lvdisplay | grep ovirt-node-ng-4.1.1-0.20170303.0+1
LV Path /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1

fdisk: cannot open /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1: No
such file or directory
# vgchange -ay
# fdisk -l /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1 (then worked)
But the upon reboot it came back to 4.1.0 as if 4.1.1 never existed.
Is there any known solution of a full Node reinstall is the recommended ?
Thanks
Fernando

iscsi failover MD3820i
by Marcin Kruk
Hello I have got Dell MD3820i and four interfaces which was connected to
the hostst via switches.
But there is only one IP which I can set during the configuration of iSCSI
RHV storage.
Everything has been fine until I pluged off cable from the storage NIC
interface with IP configured in the RHV iSCSI section.
Now VDSMD got problem because it tries to connect via iscsiadm with exact
IP and does not use the configuration from the /var/lib/iscsi/, where are
tree extra paths to achive the LUN. In multipath -ll I see an active path,
of course with the second storage interface IP

ovirt don't give "initiator name" to cinder when I'm launching a VM with a cinder volume
by herve
dear ovirt user community,
I can't sort out an ovirt issue I got with cinder for weeks, I hope
someone could give me a clue...
From mi ovirt manager 4.1, I can create and delete a cinder volume or
attach and detach a cider vomume from an ovirt VM.
The problem is I never had been able to launch an ovirt VM with a cinder
volume attached to it.
I just got a simple message from ovir web gui: "Failed to run VM
centoscinder (User: admin@internal-authz)".
what i am using is
a RDO newton release of openstack. the backend of cinder is a local lvm,
and the openstack VMs can use the cinder volumes from other compute node.
from the ovirt 4.1 fedora 24 server:
[root@rhevf24 ~]# rpm -qa | grep ovirt-engine-4
ovirt-engine-4.1.0.4-1.fc24.noarch
ovirt-engine-setup-plugin-ovirt-engine-4.1.0.4-1.fc24.noarch
[root@rhevf24 ~]#
from the ovirt server , through the iscsiadm command, I can see for
example the 2 disks attached to 2 diffents openstack instances,
but not the one I just created from ovirt which is attached to nothing ,
from the openstack rdo point of view.
[root@rhevf24 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.122.36
192.168.122.36:3260,1
iqn.2010-10.org.openstack:volume-f4c6c55c-e383-4781-8d24-d41b55870d29
192.168.122.36:3260,1
iqn.2010-10.org.openstack:volume-58844340-741e-45da-9aa7-b0ed08391df3
as I said previously From ovirt I can create /delete in cinder and
attach/detach volumes to ovirt VMs I don't get any troubles with that.
----
in ovirt engine.log almost nothing , except it can't aquire lock.. but
in openstack cinder, and with tcpdump I get more informations.
tcpdump give me when ovirt intent the iscsi connection something like:
json.key == "os-initialize_connection"
{. "os-initialize_connection" : {. "connector" : { }, },}
and I get from "tail -f /var/log/cinder/volume.log" :
2017-03-07 16:45:06.889 3856 ERROR cinder.volume.targets.iscsi
[req-b6d39a14-f9ea-4552-91e7-5db811217b1e
dd1dd33789274fb7ba228c75a07c0e94 0f68893965dd4f5dafd319cbffb33bb4 -
default default] The volume driver requires the iSCSI initiator name in
the connector.
...
...
2017-03-07 16:45:06.891 3856 ERROR oslo_messaging.rpc.server
InvalidInput: Invalid input received: Connector doesn't have required
information: initiator
So it looks like I didn't get or I can't provide the initiator name I
want to be connected to.
Cinder can't obviously guess which one I want. that's more or less
what's the cinder's logs are telling me.
I have searched for a long time in internet, it looks like at least
since ovirt 3.6, cinder is ont anymore an issue, and can even be
integrated with a ceph back end to ovirt...
cinder model an client are installed in the ovirt server...
Somebody get any clue to tell ma where i made a mistake in the cinder
integration with ovirt , which seems to be correct regarding the
create/delete attach /detach volume behavior...
Thank you
Herve

Second node ovirt 4.0 no ovirtmgmt bridge, non-operational issue
by Ian Neilsen
Hi all
I currently have a non-operational second node in my "ovirt 4.0
hosted-engine" installation running on Centos7, kernel
3.10.0-514.10.2.el7.x86_64.
When I ran "hosted-engine --deploy" on the second node, it produce the
following error(see bottom of email).
I now cannot set the second node into operational mode, no matter what I
try. I did notice a few things though.
#1 - no ovirtmgt bridge was created during hosted-engine deploy; should I
create this bridge and retry?
#2- vdsmd keep throwing start errors before I ran hosted-engine deploy. I
ran vdsm-tool configure --force this seem to fix it.
#3 - second node complained of no fencing agent, so I added in a DRAC fence
agent and it worked/tested fine. But still not able to go opertional on
second node.
#4 Ive tried restarting vdsmd, ovirt-ha-agent and ovirt-ha-broker. Both the
agent and broker throw error messages.(see bottom of email for errors)
Any advice of where to look next, what to fix?

oVirt global utilization trend
by Abi Askushi
Hi,
I see that the global utilization 24h trend graph (CPU, RAM, Disk) at
dashboard is showing only the last 3 hours. The line for previous hours is
flat (see attached). I remember that on a previous installation I had
tested it was showing the full 24 hours. Tried to run again engine-setup
but issue remains.
Any suggestions?
Thanx,
Alex

Problems adding iSCSI storage domain
by Simon Vincent
I have setup a small cluster running a hosted engine using iSCSI. I tried
to add a new iSCSI storage domain but this failed as not all hosts could
access the storage server. I fixed this problem but it now does not let me
add the new storage domain as it shows "lun is already part of storage
domain". The engine does not show any storage domains but if I look in the
database it shows up there.
How do I remove this broken storage domain and then re-add it?

3.5->3.6 did not import hosted engine storage domain
by Chris Adams
So, on to my next upgrade issue (sorry for all the questions and thanks
for everybody's help)... I upgraded my test cluster from 3.5 to 3.6
(latest version of each, all on CentOS 7 except the engine on CentOS 6).
Now I'm working on the next step, upgrading to 4.0 and migrating the HE
to the appliance.
When I went from 3.5 to 3.6, I ended up with an fhanswers.conf in the
shared storage that only contained "None"; I fixed that based on some
mailing list messages (but just mentioning it in case it could be
related).
My problem is that the hosted engine storage domain did not get imported
into the engine DB, so I can't proceed with "hosted-engine
--upgrade-appliance". I didn't see any errors, so I'm not sure how that
happened. I'm also not sure how to fix that.
Suggestions?
