[ovirt-users] Graphics are turned upside down when install QXL in Windows

2017-03-06 Thread 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.

I'm using oVirt 3.6.7 now. I want to enable tunnel migration feature. 
But when i set tunnel_migration value of vm as Ture through python

so i use SDK), then migrate the vm i got the following error message:

[ovirt-users] Storage balancer project

2017-03-06 Thread nicolas 

Hi,

I implemented a storage domain balancer [1], i.e. a script that tries to 
keep all storage domains under a defined threshold. We use our oVirt 
infrastructure for teaching so have several hundreds of users and cca. 
800 VMs at this time, so something like this is really needed 
considering that when students create their VMs they tend to create 
their disks under the same storage domain (normally the first available 
one). This results in one or two heavily used SDs and the rest 
underused.


I tried to keep it as simple as possible and doesn't have many features, 
but it seems to work (I tried it under our conditions: About 10 SDs, 
relatively highly used). If someone want to improve something on it, 
pull requests are welcome.


Might also be an inspiration on [2].

Regards.

Re: [ovirt-users] [ANN] oVirt 4.1.1 First Release Candidate

2017-03-06 Thread Christophe TREFOIS 
Good question.

But I can assure you that not everything is golden goose.

Sometimes there is legacy, lack of knowledge, and so on, and there are many use 
cases where a full test env is not a given.
It is desired yes, but currently not an option.

By the way, to quote some famous people, everyone has a test environment, only 
few of us are lucky enough to have prod env as well.

And based on the problems we encountered recently, which were upgrade related, 
it would have been difficult to have a 1:1 test env anyway, as this issue for 
sure would not have been caught.

[ovirt-users] oVirt Nodes Monitoring

2017-03-06 Thread 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
Fernando

ovirt-node is designed to just update itself as a firmware.
any additional packages is treated as 3rd party rpm which will be persisted
on upgrade.
In order to install the hooks on node you need to enable the ovirt
repositories in /etc/yum.repos.d

For installing the hooks on al new hosts during deploy you can do on the
engine host / vm:
# echo  vdsm-hook-macspoof >
/usr/share/ovirt-host-deploy/plugins/ovirt-host-deploy/vdsmhooks/packages.d/vdsm-hook-macspoof.centos
# echo  vdsm-hook-nestedvt >
/usr/share/ovirt-host-deploy/plugins/ovirt-host-deploy/vdsmhooks/packages.d/vdsm-hook-nestedvt.centos

And whenever you'll add a new node, those packages will be installed. Just
remember to enable the repository before adding the new host to the engine.
Packages and configuration will be persisted on upgrade.

As a side note:

What kind of data center do you run, that lacks any test environment?

If you don't have a testbed, than you have far worse problems than the
number of bugfixes and things which might (not) work in a new ovirt version.

Re: [ovirt-users] VM Permissions (3.6)

2017-03-06 Thread Oved Ourfali 
Hi Alexis,

Permissions in oVirt consist of three parts:
1. The user/group
2. The role
3. The object

So, if you want a user to be able to "use" a VM, it should be enough to
grant him a UserRole on the VM object (no need to go to the system
preferences for that one).
If you want a user to be the owner of a VM (allows more actions on that VM
than UserRole), then you should grant him with UserVmManager on the VM
object.

The role itself consists of actions that are allowed to be done with it.
You can view these actions in the UI through the system preferences dialog.

When you grant permissions on the system preferences dialog, then it means
the "object" you grant on is the "system" object, which is in the higher
part of the objects tree.
Normally you won't need that for users.

As for managing permissions, it can be done either via the UI, or the API,
or one of the SDKs.
I guess it is a matter of preference and needs.

Cheers,
Oved

Re: [ovirt-users] [ANN] oVirt 4.1.1 First Release Candidate

2017-03-06 Thread Andrea Ghelardi 
I somehow agree to this statement
While ovirt team is really doing an awesome job and ovirt is getting more and 
more polished at every release, a +100 critical bugfixes statement in a minor 
release tends to underline the flaws of 4.1.0 rather than the good things of 
4.1.1

Considering that

A)  there could be no test environment to check the upgraded version 
behavior and

B)  the upgrade itself may require more than a bit of effort when there are 
dozen hosts and multiple clusters involved,
this does not really encourage to always push the datacenter to the latest 
version available, especially if the in-production version is not misbehaving.

Please note I'm just sharing our company view and not blaming anyone.

 Note that between 4.0.6 and 4.1.0 there were ~1100 bugfix+enanchement
 fixed and in 4.1.1 there will be other ~400 bugfix+enhancements
 Being the 4.1.1 release scheduled in ~1 week, I would wait for it.

Those packages should be available from the oVirt repos as they are
built together with the vdsm package. Perhaps node has special
exclusions. Referring again to the node maintainers. Sandro? Fabian?

This was just GIU suggestion when I was creating the cluster it was asking

data.
I am not so sure if I can change the type of the glusterfs to triplicated
one in the running system, probably I need to destroy whole cluster.

We  have also several huge systems running with zfs quite successful over
the years. This was an idea to use zfs + glusterfs for the HA solutions.

Yes I saw that glusterfs is CPU/RAM hugry!!! 99% of all 16 cores used just
for healing 500GB vm disks. It was taking almost infinity compare with nfs
storage (single disk+zfs ssd cache, for sure one get an penalty for the

Hi Sandro,

We upgraded now to 4.1.0, just have to upgrade now the hosts.

We don’t have test env, so we’re in prod.

If we encounter some bugs fixed in 4.1.1, how could get to 4.1.1 RC?

Thanks,

Note that between 4.0.6 and 4.1.0 there were ~1100 bugfix+enanchement fixed
and in 4.1.1 there will be other ~400 bugfix+enhancements
Being the 4.1.1 release scheduled in ~1 week, I would wait for it.

Hello,

the packages you're referring are not available through yum on hosts.
I've seen that only specific packages are included from repos, does
these packages are excluded?

OVF is standard format for describing a VM:
https://en.wikipedia.org/wiki/Open_Virtualization_Format

All the VM that have a disk on a storage domain are stored in
the OVF_STORE disks using OVF format, so you can restore
all the VM from storage if you lost your engine database.

Or, if you want to move entire storage domain from one setup to another,
you can detach the storage domain from one setup, attach to the other
setup, and import all the VMs.

The OVF is also used by hosted engine to obtain engine vm setup from
storage, and start the engine vm after a host is rebooted.

[ovirt-users] Ubuntu VM does not complete reboot cycle without Console Open

2017-03-06 Thread Anantha Raghava 

Hi,

I have been observing that Ubuntu Precise VM, if restarted using a 
crontab at a given time, stops at the OS / Kernel Selection screen and 
does not complete the reboot. If we issue the reboot command with 
Console open, the same command works without any issues and the VM boots 
properly. This issue happens only with Ubuntu Precise and not with 
Trusty or Xeniel or even with any of Rehat distributions or CentOS.


Interestingly, it doesn't happen with VMWare ESXi.

I also read somewhere that this issue is with VDSM 3.6 and it seems to 
continue with VDSM 4 as well.


Any suggestions in this regard.
