[ovirt-users] Maximum time node can be offline.

2018-02-07 Thread Thomas Letherby
Hello all,

Is there a maximum length of time an Ovirt Node 4.2 based host can be
offline in a cluster before it would have issues when powered back on?

The reason I ask is in my lab I currently have a three node cluster that
works really well, however a lot of the time I only actually need the
resources of one host, so to save power I'd like to keep the other two
offline until needed.

I can always script them to boot once a week or so if I need to.

Thanks,

Thomas

[ovirt-users] Issue with 4.2.1 RC and SSL

2018-02-07 Thread ~Stack~
Greetings,

I was having a lot of issues with 4.2 and 95% of them are in the change
logs for 4.2.1. Since this is a new build, I just blew everything away
and started from scratch with the RC release.

The very first thing that I did after the engine-config was to set up my
SSL cert. I followed the directions from here:
https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/

Logged in the first time to the web interface and everything worked! Great.

Install my hosts (also completely fresh installs - Scientific Linux 7
fully updated) and none would finish the install...


I can send the full host debug log if you want, however, I'm pretty sure
that the problem is because of the SSL somewhere. I've cut/pasted the
relevant part.

Any advice/help, please?

Thanks!
~Stack~

[ovirt-users] oVirt CLI Question

2018-02-07 Thread Andrei V
Hi,

How to force power off, and then launch (after timeout e.g. 20sec)
particular VM from bash or Python script?

Is 20sec is enough to get oVirt engine updated after forced power off ?

What happened with this wiki? Seems like it is deleted or moved.
http://wiki.ovirt.org/wiki/CLI#Usage

Is this project part of oVirt distro? It looks like in state of active
development with last updates 2 months ago.
https://github.com/fbacchella/ovirtcmd

Thanks !

[ovirt-users] qcow2 images corruption

2018-02-07 Thread Nicolas Ecarnot

Hello,

TL; DR : qcow2 images keep getting corrupted. Any workaround?

Long version:
This discussion has already been launched by me on the oVirt and on 
qemu-block mailing list, under similar circumstances but I learned 
further things since months and here are some informations :


- We are using 2 oVirt 3.6.7.5-1.el7.centos datacenters, using CentOS 
7.{2,3} hosts

- Hosts :
  - CentOS 7.2 1511 :
- Kernel = 3.10.0 327
- KVM : 2.3.0-31
- libvirt : 1.2.17
- vdsm : 4.17.32-1
  - CentOS 7.3 1611 :
- Kernel 3.10.0 514
- KVM : 2.3.0-31
- libvirt 2.0.0-10
- vdsm : 4.17.32-1
- Our storage is 2 Equallogic SANs connected via iSCSI on a dedicated 
network
- Depends on weeks, but all in all, there are around 32 hosts, 8 storage 
domains and for various reasons, very few VMs (less than 200).
- One peculiar point is that most of our VMs are provided an additional 
dedicated network interface that is iSCSI-connected to some volumes of 
our SAN - these volumes not being part of the oVirt setup. That could 
lead to a lot of additional iSCSI traffic.


From times to times, a random VM appears paused by oVirt.
Digging into the oVirt engine logs, then into the host vdsm logs, it 
appears that the host considers the qcow2 image as corrupted.
Along what I consider as a conservative behavior, vdsm stops any 
interaction with this image and marks it as paused.

Any try to unpause it leads to the same conservative pause.

After having found (https://access.redhat.com/solutions/1173623) the 
right logical volume hosting the qcow2 image, I can run qemu-img check 
on it.

- On 80% of my VMs, I find no errors.
- On 15% of them, I find Leaked cluster errors that I can correct using 
"qemu-img check -r all"
- On 5% of them, I find Leaked clusters errors and further fatal errors, 
which can not be corrected with qemu-img.
In rare cases, qemu-img can correct them, but destroys large parts of 
the image (becomes unusable), and on other cases it can not correct them 
at all.


Months ago, I already sent a similar message but the error message was 
about No space left on device 
(https://www.mail-archive.com/qemu-block@gnu.org/msg00110.html).


This time, I don't have this message about space, but only corruption.

I kept reading and found a similar discussion in the Proxmox group :
https://lists.ovirt.org/pipermail/users/2018-February/086750.html

https://forum.proxmox.com/threads/qcow2-corruption-after-snapshot-or-heavy-disk-i-o.32865/page-2

What I read similar to my case is :
- usage of qcow2
- heavy disk I/O
- using the virtio-blk driver

In the proxmox thread, they tend to say that using virtio-scsi is the 
solution. Having asked this question to oVirt experts 
(https://lists.ovirt.org/pipermail/users/2018-February/086753.html) but 
it's not clear the driver is to blame.


I agree with the answer Yaniv Kaul gave to me, saying I have to properly 
report the issue, so I'm longing to know which peculiar information I 
can give you now.


As you can imagine, all this setup is in production, and for most of the 
VMs, I can not "play" with them. Moreover, we launched a campaign of 
nightly stopping every VM, qemu-img check them one by one, then boot.

So it might take some time before I find another corrupted image.
(which I'll preciously store for debug)

Other informations : We very rarely do snapshots, but I'm close to 
imagine that automated migrations of VMs could trigger similar behaviors 
on qcow2 images.


Last point about the versions we use : yes that's old, yes we're 
planning to upgrade, but we don't know when.

Re: [ovirt-users] Ovirt backups lead to unresponsive VM

2018-02-07 Thread Shani Leviim
Hi Alex,
Sorry for the mail's delay.

>From a brief look at your logs, I've noticed that the error you've got at
the engine's log was logged at 2018-02-03 00:22:56,
while your vdsm's log ends at 2018-02-03 00:01:01.
Is there a way you can reproduce a fuller vdsm log?

[ovirt-users] Migration of a VM from ovirt 3.6 to ovirt 4.2

2018-02-07 Thread eee ffff
Dear ovirt-users,

I would like to copy the VMs that I have now on a running ovirt 3.6 Data Center 
to a new ovirt 4.2 Data Center, located in a different building. An export 
domain is not an option,
 as I would need to upgrade the ovirt 3.6 host to 4.2 and (as this is an 
operation that I would have to do multiple times) constantly upgrading and 
downgrading a host, so that it would be compatible to the ovirt environment 
does not make sense.
 Do you have other suggestions?

Cheers,
Eli

Re: [ovirt-users] 4.1 slot user portal vm creation

2018-02-07 Thread Staniforth, Paul
Hello,

   After further testing and restoring the engine to a test system it 
seems that even when listing templates using the web API  it is very slow 
whereas listing VMs isn't slow.

Even if using admin@internal and  --header 'Filter:True' it's slow whereas 
without the header it's fast.

As our test system has no storage or hosts is it possible to delete templates 
from the database as a restore from October doesn't seem to have the problem.


Thanks,

Paul S.

Hello,

In the admin portal it lists the templates with no problem.

How many users using that user portal do you have? It may be just that slow 
because it's too many
Note it's completely removed from 4.2 and teh ovirt-web-ui does provide only 
limited New VM capabilities - but it should perform much better

Thanks,

We are running 4.1.9 on the engine and nodes.

Any help appreciated.

I will open the issues for that. I feel the new interface has been a 
nice improvement but if it doesn't contain all the former 
functionalities it's not useful at all. Our users create their machines 
from scratch with no template (they are engineering students and they 
need to know how to do some basic stuff).

Re: [ovirt-users] Add a disk and set the console for a VM in the user portal

2018-02-07 Thread nicolas
Sorry, but I don't understand what's the new VM portal purpose then... I 
mean, you can create a VM but you can't modify the console type, nor add 
disks, nor add NIC interfaces?


If that's how the new VM portal works, we can't upgrade our oVirt 
infrastructure because as I said, we extensively use the VM portal and 
users need to create their VMs and fully customize them.

[ovirt-users] Fwd: A possible bug on Fedora 27

Have you been able to have a look at this issue?

Thanks in advance

 Forwarded Message 
Subject:[ovirt-users] A possible bug on Fedora 27

Hi Community,

Recently we discovered that our VM's became unstable after upgrading
from Fedora 26 to Fedora 27. The journalctl log shows the following

Jan 29 20:03:28 host1.project.local libvirtd[2741]: 2018-01-29
19:03:28.789+: 2741: error : qemuMonitorIO:705 : internal error: End

Jan 29 20:10:29 host1.project.local libvirtd[2741]: 2018-01-29
19:10:29.584+: 2741: error : qemuMonitorIO:705 : internal error: End
of file from qemu monitor

A similar bug report is already present here:
https://bugzilla.redhat.com/show_bug.cgi?id=1523314 but doesn't reflect
our problem entirely. This bug seems to be triggered only when a VM is
shut down gracefully. In our case this is being triggered without
attempting to shutdown a VM. Again, this is causing the VM's to be
unstable and eventually they'll shut down by themselves.

Do you have any clue what could be causing this?
