[ovirt-users] Setting DNS servers problem on ovirt

2016-10-31 Thread Thing 
Hi,

I have installed IPA across 3 nodes.  In order to point the ovirt server at
the new IPA/DNS servers and to clean up I ran engine-cleanup aiming to
delte the ovirt setup.   However it seems even though I ran this something,
"vdsm?" is still running and controlling the networking.

So down under /etc/sysconfig/network-scripts I see,

=
/etc/sysconfig/network-scripts
[root@ovirt1 network-scripts]# ls -l
total 256
-rw-rw-r--. 1 root root   130 Nov  1 10:32 ifcfg-enp0s25
-rw-r--r--. 1 root root   254 Sep 16  2015 ifcfg-lo
-rw-rw-r--. 1 root root   252 Nov  1 10:32 ifcfg-ovirtmgmt
8><-
==

So my first Q is why when I run engine-cleanup isnt the networking cleaned
up?  should I file this as a bugzilla?

After that I can see that ifcfg-ovirtmgmt is still controlling DNS,

==
8><
[root@ovirt1 network-scripts]# tail ifcfg-ovirtmgmt
ONBOOT=yes
IPADDR=192.168.1.34

MTU=1500
DEFROUTE=yes
NM_CONTROLLED=no
IPV6INIT=no
DNS1=192.168.1.240
[root@ovirt1 network-scripts]#
===

So I tried to set,

DNS1=192.168.1.31
DNS2=192.168.1.32
DNS3=192.168.1.33

rebooted and, no I see,

DNS1=192.168.1.240 again

So I also see that the vdsm service is still running,

why after cleaning up is this still active?

Next, I have grep'd under /etc/ and cannot find where its getting its
obsolete network DNS info info from.

So I need to know where this info is stored? so I can edit is via the CLI?
database?

There is no web ui running as engine-cleanup has removed that so I cant
work via the web ui.

Is there anything else I need to manually stop, disable and remove after
running engine-cleanup?

thanks

Hi Ben. Actually exactly today REST API for uploading disks was introduced
to master. It is supposed to get into the next 4.0.Z version, so if you
want you can update your version soon enough and use the API.

When you'll have the right version, you can use examples from "/api/Model"
to upload disks using oVirt's Python SDK.

If you need any help, please feel free to keep asking on the list.

Re: [ovirt-users] Kill a failed VM import

2016-10-31 Thread Juan Pablo 
Chris, which version are you using? I have the same issue running 4.0.4
importing a previously exported vm from export domain.
I have tried:

vdsClient -s 0 getAllTasksStatuses
found the task, did a stopTask and then let the engine clear the db.
no luck. the task is not shown anymore with vdsClient but it remains at the
engine web interface. I guess its a ddbb error...

ideas?

[ovirt-users] mass upload of disks?

2016-10-31 Thread Ben De Luca 
Hi,
I was wondering if there was a method on the cli/script to mass upload
disks to ovirt. The web loader is great, but also I have 20 disks that I
really just want to upload via shell.

I can't seem to find a tool to do it, I have found ovirt-image-uploader
(but that's for ovf files).

I hoped that I could just pull the date directly off nfs but that
doesnt seem to be possible, or I am blind?

Thanks

FTW, attaching physical local drives to VMs also works well.
Disks -> New -> Direct LUN -> Storage Type: Fibre Channel -> Use Host…
Your disk doesn't have to be Fibre Channel. Just any direct attached disk works 
well.

Re: [ovirt-users] Local and Shared storage in same datacenter

2016-10-31 Thread Pavel Gashev 
I think it's all about online VM migration. oVirt doesn't support online VM 
migration together with online storage migration. So any storage has to be 
accessible from any hosts in a datacenter. That's why local storages are too 
restricted.

Converting Local storages to Shared removes the restriction. Avoiding NFS layer 
locally removes the NFS performance drawback. And both allow to adhere to the 
oVirt way.

Why this 'workdaround' to share a local storage as NFS instead os just 
use it as a 'normal' Local storage ? Looks more like a chewing gum.

Is there any work in progress to change the way this storage pool 
manager works ?

Re: [ovirt-users] Local and Shared storage in same datacenter

2016-10-31 Thread Pavel Gashev 
Mike,

As workaround it's not very hard to create a mount command wrapper that 
converts local NFS mounts to bind-mounts. The propper way I think is to patch 
the VDSM service to handle local NFS mounts. In result, a NFS storage will work 
like a local storage if it's local.

I installed a nfs server on the hypervisor and am using it that way at 
the moment.
It feels 'wrong' but it seems to work okay and it is fast as far as I 
can tell.
Still would like to see another solution without the added latency of 
nfs and be able to utilize directio, etc.

Hi Pavel,

Mike,

You can share and use your local storage via NFS. So all your storages are 
shared, and can be used in the same datacenter.
I installed a nfs server on the hypervisor and am using it that way at 
the moment.
It feels 'wrong' but it seems to work okay and it is fast as far as I 
can tell.
Still would like to see another solution without the added latency of 
nfs and be able to utilize directio, etc.

Subject: [ovirt-users] Local and Shared storage in same datacenter

Hi guys,

There have been a few related questions already that I could find, but I
did not find anything relating to my specific use case.

Currently it is not possible to mix local storage with shared storage in
the same datacenter.
The reason seems to be because of the storage pool manager (SPM).
This is a role in the datacenter provided to one specific host.

While I understand that this makes having local storage impossible, I
believe there is a use case to have local storage in a shared storage
datacenter.
Consider the following:
I have a few applications that require 1 milli second latency and at
most 2 milli second.
That is not consistenly achievable with shared storage, to that end I
added flash storage to a few hypervisors.
About 5% of my servers require this and are not that resource hungry to
require a dedicated physical server.
That same 5% also has no requirement to be migrated if a host fails.

So in short I have 5 heavy hosts running ovirt with a shared storage
domain on NFS for 95% of my servers.
All running fine, but I am now unable to run my remaining 5%.

To finish up my summary I have been testing various virtualization
technologies, like VmWare and Hyper-V.
They allow such configurations as I mentioned.

I already had some chat on irc with various guys and they suggested that
I put this on the mailing list, so here goes.

My suggestion would be to evoluate from SPM to SDM.
SDM stands for Storage Domain Manager.
This would create the possibility to have all nodes in the datacenter
participate in the storage handling.
A extra benefit would be that local storage could be added.

What do you think?

Thanks for reading.

I have 5 hosts and dedicating 2 hosts for 5% seems a gigantic waste if you

So I cannot do that.


Not real solutions, but you might consider:

Using nested-kvm and "virtual hosts"

Copying the data to a local scratchpad upon every reboot, and perhaps rsync
back to shared storage on shutdown.

Thanks, it might be an angle to look at.

[ovirt-users] Updated ovirt-guest-agent puppet module

2016-10-31 Thread René Koch 

Hi,

there's an updated version of scrat14/ovirt-guest-agent available at 
https://forge.puppet.com/scrat14/ovirt_guest_agent


Latest version includes support for installing oVirt guest agent on RHEV 
hypervisors in addition to oVirt nodes.
Furthermore this module will now use rhevm-guest-agent-common for RHEL 7 
machines from rhel-7-server-rh-common-rpms repository by default 
(instead of ovirt-guest-agent-common from EPEL).

Hello oVirt community,

In oVirt 4.0.4, I can see ram/cpu usage in a very nice way, but I can not 
access easily the total RAM and number of CPUs. 
The only way to find this information in GUI is to edit a vm and see the system 
tab (and that's when the "edit" context menu is available, which is not always) 

Am I missing something? 
This information is very usefull and sometimes critical (when migrating VM to 
hosts which are already low on free RAM, specially when balloning is involved) 

I would like to see this information always on screen, like a (un)checkable 
column... does it seem doable ? 
Maybe it would be possible to show it while hoovering the memory/cpu 
information with the mouse ? 


You can vote for custom columns :)

Thx for the advice Barak!

I was looking for a roadmap to follow, like the "trello" one used for the
openshift project https://trello.com/b/nlLwlKoz/atomicopenshift-roadmap but
I was not able to find one. I love to hear things like the "SPM was planned
to be removed" as it gives me a better understanding of the direction the
project has. Any good resource to follow this and other things to come?

Please don't take my statement as being official in any way. Despite
writing from a @redhat.com address, I'm writing my personal thoughts.

I have stated that I've no data to back what I've said. This is all
just a guess based on what I know of oVirt/RHV development processes.
I'm most certainly not someone who makes decisions about any of theses
things.

Please do not take my statement as indicating of any conscious design
decision. I was just trying to gauge where oVirt/RHV development might
head given that RedHat typically puts its resources where its current
and potential customers tell it do. Case to point:

1. Ephemeral local state VMs are supported with the scrathcpad hook because
   its been shown to be useful for Build/Test/CI systems.
2. Singular host with local storage and non-migrating VMs is supported for
   cases where one simply wants resource convergence.

The 3rd case we're discussing here where the same host can run both
local persistent VMs and migrating ones had not been supported so far.
I'm __guessing__ that this is because demand seen so far did not
outweigh
the technical difficulty to achieve this (Just to indicate the difficulty,
the SPM was planned to be removed in 4.0, it did not make it).

> Anyways, question has been answer "yes, is technically possible but by

This is definitely not the bottom line, I way trying to guess and
explain why this __did_not__ happen __so_far__. I never meant to say
it will not.

If you are a RHV reseller or integrator, your input is very valuable
for RedHat. While this list is one way to reach some RedHat
developers, you should certainly make an effort to use other channels
available to you to make your input known.

Not sure how you got this impression from current discussion. On the

[ovirt-users] Chinese oVirt community

2016-10-31 Thread Yedidyah Bar David 
Hi all,

Recently, more and more questions are posted to users@ovirt.org in
what seems like a result of a google translation of Chinese to
English. These are usually hard to understand, and I expect the
replies are also hard to understand. A recent example is [1].

Two years ago there was a discussion [2] about this on
users@ovirt.org. Now, when searching, I find:
1. There seems to have been a domain ovirt-china.org , but it's dead
now (no info about it in dns or whois). The only version of it I can
find on archive.org is [3].
2. There is a github org [4].
3. There is a google group [5] , but it requires registration to view
(and I didn't try to register).

If there is an active Chinese community of oVirt users, perhaps we
should give it more publicity, to make it easier to find. Otherwise,
perhaps we can help by creating a list on lists.ovirt.org , or
something like that.

If a GPU is used as a passthrough device can it be used on several vm's or
is it restricted to 1 vm?


Single card for single VM meaning 1:1 mapping only for now.


If 2 GPU's are used can 1 be used as a dedicated passthrough to 1 vm and
the other shared between the remaining vm's?


As stated above, no. Most typical home lab setup uses 2 GPUs, one for
hypervisor and other one to be assigned to a VM.


Is CentOS/RH the best platform for ovirt?


For playing around and general usage, yes (in my opinion :) ).


Is it okay/advisable to load the latest kernel, (4.8 ish), on to CentOS
before installing ovirt?


I wouldn't really do that, you'd have to bump up version of KVM,
possibly QEMU and libvirt -- in the end you'd end up running fedora.

Re: [ovirt-users] Local storage & shared in same cluster

Thx for the answsers. I see that it's the second time that someone from RH
points out that customers are not interested in this feature. While I can't
argue with that, what I do can say is that "non-customers" (most of
companies out there using vsphere or hyper-v) feel dissapointed towards
this solution for things like this one (for this case, 2 of my customers
are missing this, we are deploying RHV to one of them this week).

I don't see how this lack of flexibility is something good, and so far from
my experience with customers which I'm trying to convince to start using
RHV, when they finally do agree to start with one or two servers (following
the RHCI roadmap evolution to the hybrid cloud), they see things like this
and dismiss this solution sooner than later.

Anyways, question has been answer "yes, is technically possible but by
design it is not going to happen", and I wouldn't like to convert this
thread or abuse your kindness deviating the subject :)

Thx again guys for the help,

Not real solutions, but you might consider:

Using nested-kvm and "virtual hosts"

Copying the data to a local scratchpad upon every reboot, and perhaps rsync
back to shared storage on shutdown.
