As already mentioned in the thread, perhaps Boxes can do the job, at
least on Gnome.
See
http://community.redhat.com/blog/2014/10/gnome-boxes-3-14-unboxed/
and https://www.ovirt.org/images/6/6c/Fergeau-ovirt-boxes.pdf for

yes, it is a mobile client.
There is a way to run it as a google chrome app using arc
welder so on a desktop (on fedora at least it works for me).
But this way it is more interesting than useful I'd say...

That's good to know. Is there a wiki page/script for how to externally clone
a VM for export?


need to check per storage type (which we'll do). for now, if you can 
clone it, we can register it.

netapp has a service that provides this in an integrated way.

Import existing, don't try to create one.

With hostusb some more host-dev virtualization could be added. Top of my

these should be covered in 3.6, though have some caveats, please try and

I had the same goal, but for multiple independent ovirt installs. My
work-around is to deal with it outside ovirt.

- create generic nfs export for my iso mirrors
- create iso export points for each install
- add iso mount to each install
- manually (or using puppet, etc) add mirror mount on each host node
- run a script that creates a symlink in each ovirt iso mirror for all the
   isos in the mirror export
   - 3.5 handles iso images in subdirectories, but 3.4 does not [1], so the
 script creates symlinks for every iso image in the top level of the iso
 export for 3.4, while only needing a symlnk to the distro directory fro
 3.5.

It's a hack, but it works.


This should work without any hacks. An ISO domain can be shared between 
multiple DCs or Engines.

Tal?





Robert

[1] 3.4 will descend to subdirectories to display the list of iso images
when attaching them in the UI, but the host will fail to boot because it
can't find the image unless it's at the top level.

Some "little things":

nfsv4 support (http://www.ovirt.org/Features/NFSv4)



are there specific gaps here still?


libgfapi


did not make it iirc, though some progress was made.
allon - is that opt-in, or totally not in codebase?



drbd support (http://www.ovirt.org/Features/DRBD)


Some concepts from IBM PowerHA look interesting:

I don't know if the term is correct but we'd like to be able to
group vm's together and create dependency's between them.
Something like, first start the database vm then the
authentication vm and last the webserver vm.


not in 3.6. if still relevant, please ask again in next poll.



/resource groups

(http://www-01.ibm.com/support/knowledgecenter/SSPHQG_7.1.0/com.ibm.powerha.concepts/ha_concepts_cluster_resources.htm)/
//Resource groups/allow you to combine related resources into a
single logical entity for easier configuration and management.
The//PowerHA SystemMirror//software handles the resource group
as a unit, thus keeping the interdependent resources together on
one node and keeping them highly available./
//


vm affinity is supposed to cover some of the above?



  * /Identifying the set of cluster resources that are essential
to the operation of an application, and combining those
resources into a resource group./
  * /Defining the resource group policies and attributes that
dictate howPowerHA SystemMirrormanages resources to
keep them highly available at different stages of cluster
operation (startup, fallover and fallback)./

/By identifying resources and defining resource group policies,
thePowerHA SystemMirrorsoftware makes numerous cluster
configurations possible, providing tremendous flexibility in
defining a cluster environment tailored to individual requirements.
/

We would also like to be able to split a cluster between two

/linked clusters/

/http://www-01.ibm.com/support/knowledgecenter/api/content/SSPHQG_7.1.0/com.ibm.powerha.concepts/ha_concepts_multi_linked.htm/
/A linked cluster is ideal for situations where each site is
located at a different geographical location. Typically, the
sites are far enough apart so that they cannot conveniently
share a common storage area network (SAN). Each site must have
its own active repository disk, and any backup repositories.
Linked clusters always use unicast to communicate between sites.
Linked clusters are a useful part of high availability disaster
recovery (HADR)./

We are currently developing a benchmarking system for ovirt and
test failover stuff by hand. Something like this would save
people a lot of time
/Cluster test tool/

/http://www-01.ibm.com/support/knowledgecenter/SSPHQG_7.1.0/com.ibm.powerha.concepts/ha_concepts_test_tool.htm/

/The Cluster Test Tool is a utility that lets you test
aPowerHA® SystemMirror®cluster configuration to evaluate
how a cluster behaves under a set of specified circumstances,
such as when a node becomes inaccessible, a network becomes
inaccessible, a resource group moves from one node to another,
and so forth./

/You can start the test, let it run unattended, and return later
to evaluate the results of your testing./

/If you want to run an automated suite of basic cluster tests
for topology and resource group management, you can run the
automated test suite from SMIT. If you are an
experiencedPowerHA SystemMirror//administrator and want to
tailor cluster testing to your environment, you can also create
custom tests that can be run from SMIT./

/It is recommended to run the tool after you initially
configurePowerHA SystemMirrorand before you put your
cluster into a production environment; after you make cluster
configuration changes while the cluster is out of service; or at
regular intervals even though the cluster appears to be
functioning well./


this could be an external utility, rather than core to ovirt?

I've always thought it would be a good idea to have a 'storage agent' to
run on storage domains, which could perform some operations more optimally
that the current system. For example, exporting/importing domains currently
reads the whole VM image over the network, then writes it back. In my case,
my storage is all located on the smae NFS server, which could simply do an
OS copy locally, instead of reading/writing gigabytes over the network. I
don't know if other storage type could perform similar optimizations



not in 3.6. doing native storage operations is for sure a top item in 
the storage list going forward.
notice you can do these operations today at disk level and register the 
externally cloned disks via the REST API.

since 3.5 you can also detach and attach storage domains across DCs/Engines

You can also export, manage, and view different log types.

Performance metric similar to what VMware calls "CPU Ready" would be very 
useful if it was available in the VM details in the admin portal.


It would provide great visibility on VM's performance in an environment with 
CPU overallocation.



I don't think we covered this in 3.6 (doron/michal)?

I guess what is asked for is something working "out of the box".

Yes It's supported by hostusb hook,
But this needs access to the host to list what what devices are
installed.
I have used once vSphere, and it allows to select which device to
attach,
I guess it would be nice to have this in future releases .

 Sure you will need more components, but we don't want to
 duplicate the effort,
 implementing ceph support directly in ovirt. Using
Cinder we can
 reuse the
 existing ceph support, and gain also support for other
Cinder
 drivers for
 free.

 On the host side, we will have of course ceph specific
support,
 so you will
 be able to create ceph volumes directly, and use vdsm
api to
 start vms using
 these volumes, if you want more "direct" support.

 I think this is the general long term approach; integrate
 openstack components
 instead of re-implementing the wheel.

For God's sake, please, prevent "secondary" storage domains (anything
other than the master, especially iso and export) to completely block
the whole thing when being unavailable.
To many users suffered from this in the last two years I participate at
this mailing list (including me).



removing the SPM (and the concept of master domain) made a lot of 
progress, but was deemed not cooked/stable enough to be merged for 3.6, 
so still in progress.

Opteron G1 is the first supported AMD processor

Re: [ovirt-users] Cannot add Posix Storage

Hi guys,

I think I found the source of problem. The oVirt's documentation says:

Any POSIX compliant filesystem used as a storage domain in oVirt *MUST*
support sparse files and direct I/O.

MooseFS is based on FUSE drivers so it doesn't support direct_io.

My question now is - Can I disable require of direct_io in oVirt? If not
in any option, maybe by little changes in source code?
Why would I do that and why I'm not afraid about I/O performance?
Because I use MooseFS via NFS now and it works perfect, so that's why I
think that Direct I/O is not necessary!



the direct_io requirement is about robustness, not performance. it is 
meant to prevent data corruption in various cases

trust me they want to get rid of this more than we do (think about them

hopefully the new upload/download api in 3.6 will solve this.

Re: [ovirt-users] Ovirt 3.5.x Power failure recovery

[Itamar Heim]

On 02/09/2015 04:50 AM, Raymond wrote:

Hi,
Long time read-only user here :)
Unfortunately I need some info which I can't seem to find in the archives and 
on Google.

In the past 5 months we’ve had two very rare occasions of power failures in my 
hometown.
First one was a ms during spike or drop, just enough to cause a reboot, the 
other was a 30min failure.

Problem
After the power failure my ovirt nodes boot into CentOS 6.6 and are running 
fine.
In both cases my ovirt-engine-VM wouldn't start due to service Postgresql not 
starting.
I tried some things before reverting back to an older DB snapshot that was on 
the VM disk, but still not working.
Postgresql is not starting due to Duplicate UUID

My solution
Calm down girlfriend and don't sleep
Reinstall 1 node, create new ovirt-engine, recreate VM's and copy VM disk data 
from old store to new store.
Add second node

Other solutions I can think of
1. Start cluster without reinstall ;)
2. Buy UPS (€150 one time, extra €60 yearly power usage = €450 in 5 years)

At this moment I’m 1 click away from buying the UPS, but I prefer a more 
elegant solution.

After the last power failure I did NOT reinstall my second ovirt node and the 
old engine is also on storage available.
Is there someone that wants some data to troubleshoot/analyse?

Or is this just one of those things? Buy the UPS and get on with your life?

Short HW overview
2x ovirt 3.5.x (i3/32GB ram,1Gb eth VM network, dual x520 NFS eth)
1x NFS (i3/4GB ram, 5TB SAS and 6TB SATA on Dell PERC,1Gb eth mgmt, dual x520 
10Gb)

1Gb is used for VM networking, the 10Gb is connected via DAC cables and runs 
NFS-storage.
This works great! Whole cluster runs below 120w and VM disk performance is 
around 700MB/s :)
I bought all the HW with power usage in mind, PicoPSU's and 35w CPU's in all 
nodes.
So adding 30w extra just for the UPS feels a bit like killing an elephant 
with tissues...

kind regards
Raymond

engine and import the data domain

(i assume there is a way to fix the postgres issue itself as well)

Hi all,

I'm planning to migrate my ovirt el6 hosts to el7.
Excepting that el6 will not be supported in next release of ovirt, is
there a difference of performance between el7 and el6?
I mean, are qemu or libvirt for example at the same level of
performance/capabilities in el6 than in el7 (knowing that qemu-kvm 0.12
is still backported on el6) ?
I heard that el7.1 will support live merge, if true will el6.7 support
it as well or the difference between them is there?


I'm not aware of plans to backport live merge to el6.7
el7.x is expected to have much newer versions of qemu/libvirt than .el6.

Subject: [ovirt-users] Local and remote storage?

Hello,

I've run into an odd problem with oVirt 3.5.1.

I've two sets of VMs:
A) some fairly critical VMs which need HA and have access to shared storage
B) some less important systems which can be reconstructed in the event
of a disaster

My plan was to use the slack disk on my oVirt nodes to host the 'B'
systems while still allowing the 'A' systems to run there.  This seems
to not be allowed[1].

Is there a way I can utilize both the spare disk on my compute nodes and
have HA configured for some VMs with shared storage?


Currently indeed each datacenter must be configured as a shared or local 
storage one, no mix for the same datacenter.

For the next release (ovirt 3.6) we are going to have oVirt and GlusterFS hyper 
converged: you'll can use each host both for virtualization pourposes and for 
storages ones sharing the local spare disks into a shared GlusterFS volume to 
be used by oVirt hosts.
So you can also have HA capabilities and so on for the VM stored on the host 
disks shared in a GlusterFS volume; at the same time you could still use you 
state-of-the art SAN for critical VMs.

Here you can find some info an this architecture:
http://www.ovirt.org/images/6/6c/2015-ovirt-glusterfs-hyperconvergence.pdf

Than we are also going to have self-hosted engine over GlusterFS.


Pat

[1] http://www.ovirt.org/OVirt_Administration_Guide#Preparing_Local_Storage


also in 3.6 we are working on removing the hopefully last obstacle to 
allow mixed local/shared (which will require work to allow that, post 3.6)

if you need lower granularity then that, you need to give the

(at the more granular level you can use

you just need to deactivate the domain you don't want to be the master

should be possible using qemu args: -usbdevice

in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:

if this option is not exposed in ui you can use vdsm-hooks[1] to modify the

Subject: [ovirt-users]  USB Modem in a VM



Hi,

Can you tell me if I can use an USB modem through one of the
hypervisor hosts to a Windows VM ?

I’d like to install a Windows Fax Server.

Thank you for your answers.



should be possible using qemu args: -usbdevice host:vendor_id:product_id

in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:

domain type='kvm'
   name.../name
   …
   devices
 …
 hostdev mode='subsystem' type='usb'
   source
 vendor id='0x@VENDOR@'/
 product id='0x@DEVICE@'/
   /source
 /hostdev
   /devices
/domain

if this option is not exposed in ui you can use vdsm-hooks[1] to modify the 
libvirt configuration and inject such device.

Regards,
Alon

Hello,

Is there a way to add “Xeon” or another class of CPU Type to oVirt? We

The only two CPU Types that will work in oVirt are Conroe  Penryn.
Inside of a VM, it reports “Core 2 Duo”.

Host reports:

VM reports:

Is there a way to have the VM report the correct CPU? It doesn’t appear
to cause any performance or other issues, but seems to be just a display

hosts with E5- or E3- processors. Can someone confirm this

you can set the VM to use the host cpu (it won't be migratable, but you

the pool needs a master domain. if one doesn't exist, it is re-created.
this should hopefully go away in 3.6.

Re: [ovirt-users] qemu update Windows activation

[Itamar Heim]

Hello,

we just build a new cluster with FC20 + virt-preview repos enabled.
Idea behind that is to enable snapshot live merge feature. This
seems to work quite well.

The only culprit is the Windows activation. For some reasons the
VM hardware of the old qemu 1.6/seabios 1.7.3 hypervisors is
different to the new qemu 2.1/seabios 1.7.5. So the OS is no longer
activated.

We already activated the VMs twice. During first install on VMware
and then afterwards after the migration to OVirt. I have no problem
to reactivate them a third time. I have more fears that I must
reactivate them with each new hypervisor generation. That can
be quite a lot of phone calls.

An interesting article from the Proxmox guys can be read here:
http://forum.proxmox.com/archive/index.php/t-19743.html
Conclusion of the discussion: After you go from qemu 1.7 to 2.1
you can force the old hardware layout using -M pc-i440fx-1.7

Looking at the qemu command line in OVirt I can see our VMs
are fired up with pc-1.0,accel=kvm,usb=off - regardless of an
old (FC20) or a new hypervisor (FC20+virt-preview). So I would
guess that everything should work without a new reactivation.

Any ideas?

Thanks Itamar.I heard the other day that NFS v4.2 is supposed to contain
server side copy, so it's possible that we might see this kind of
support in one of more storage domain available to ovirt at some stage
perhaps next year (in Fedora at least).Is this something that Gluster
will also likely provide in a subsequent release once we have proper
gfapi support?
I'd be interested to hear if others on the list are clamouring for
server side offload support in some form.

I hope the ceph integration will provide this, though that doesn't solve

Just to note you can do this today by either:
- vdsm custom hook

- iirc, also possible by editing the specific osinfo config file to add the 
flags there

   Without these flags, my testing shows a completely idle 4 vcpu win slave

 An official supported way to import existing raw disk images would be nice.


 please review:
 http://www.ovirt.org/Features/virt-v2v_Integration


 I dont think thats what we are looking for. With this process, if I have an X size virtual disk, I have to come up with X+2X more storage to go through this silly import process. With ESXi, I just right click, add to inventory and Im off.

 Right now, Im looking at moving my AIO configuration to a new host. Ill have to create the new AIO host, create a new storage domain on the old disks, create new VMs that look like the old ones, create new virtual disks, then go rummage around the storage, figure out whats what in these user unfriendly UUID names, then move the old images onto the new ones.

 With ESXi, I just reinstall the hypervisor, create the new VM, then right click, add to inventory on the old disk image, and Im done.

 https://bugzilla.redhat.com/show_bug.cgi?id=1049604

 The concept of storage domains seems rather clumsy and limited to me.

If your existing raw images are from an ovirt storage domain you can keep it as is and import the entire storage domain or specific vms from it.
That's a new 3.5 feature. Mind you yii must first upgrade the storage domain to 3.5 before reinstalling

Re: [ovirt-users] Local storage with self-hosted mode

On 12/10/2014 05:47 PM, Jason Greene wrote:

Thanks for the suggestions.

Following Maor’s suggestion I was able to add a local domain, but that required 
maintenance mode, so I had to failure the engine over to another host to  make 
the change to the current host.

I like the appliance solution a little better, although I think it’s best if I 
were to run it under its own private KVM process unmanaged by ovirt, so that 
its possible to edit and cycle the host. Unfortunately it’s still a bit 
cumbersome as you need to have an engine appliance per system or shuffle around 
the image with some sort of disaster recovery plan.

I also looked into using gluster or cephfs as a way to share state, but noticed 
the BZs about the lack of complete atomicity leading to duplicate engines.

This is probably not the right place for dev musings, but IMO it would be great 
if in a future release there could be a solution that doesn’t require shared 
storage, which for smaller use-cases is often too pricey of a requirement. 
Ideally, under such a “horizontal” setup, each host could govern its own 
management data, and the engine could act more as an authoritative aggregator, 
thereby reducing the need for ha (if it fails just reinstall a clean one and 
let it reimport everything). It seems like most of the pieces are already 
there, with the per host-vdsm instance already containing much of the data. I’m 
guessing the missing element is having the engine support pulling that 
information as opposed to just pushing it. This is sort of like a capability 
that an unnamed proprietary competitor has, so it might have some sort of 
appeal. Of course such setups do have limitations, like you still need shared 
storage for live migrations and so on. So I certainly understand!

 the ratio
nal behind the existing design. Anyway it’s just some food for thought.

before we go so far out... gluster should work with 3 hosts, we are 
working on improving the flow for this for 3.6. today it requires quite 
a few manual steps to do so.




Thanks

Is there any way to use local storage with self-hosted mode for VMs other
than the engine? The interface does not seem to allow it. I can hack in
local storage on vdsm, but its not discovered/used by the engine (so i
assume this is because it keeps its own metadata). I tried using a posix
domain but there seems to be an expectation that the posix domain is
accessible to all other hosts.

My use case is 2 physical servers with no shared storage options, and we
need
fast I/O since the VMs are used for CI, so local storage is the ideal
setup.

Hi all,

I already manage a first engine and I'm about to deploy a second engine
to an other site.
I have thought about several possibilities:

  * create a new independant engine on the future site
  * create a second datacenter in the first engine so that all my vms
are aggregated in a same place and contact hosts with public
addresses (hum...) or via a vpn.
  * the last one is a question : like centreon does with monitoring, is
there a way to use the first engine as a master (or central) and the
second or many other ones as poller/satellite which are supposed to
deal locally with hosts?
This architecture is interesting because the workload is reparted
between several engines and once link is needed between poller and
central. More, all my vms are shown in the same ui.

Can someone give me his point of view about this?
Thank you.

no nesting of engines. you can manage a remote cluster from a single 
engine, or deploy 2 engines.
take a look at ManageIQ for orchestrating/monitoring across multiple 
engines.

You need to install package ovirt-scheduler-proxy and also enable it via

Hello,
I have 2 VMs with the negative Affinity.
I am looking some way to force the VMs running on different selected hosts.
Assuming I have hosts c1-c8: Can I tell VM to run on c1-c8 but not c2 and c4?
Thanks,

This is a nice feature, but as detaching (then removing) is needed, my
question still remains.



master storage domains is a normal storage domain. it only happens to be
using its special metadata part as the master. so all storage domains
have it. if its down, engine will automatically select another one.


Itamar, and others,

Just a little word to explain that I've just finished to test the
feature you described above (automatic master storage domain switching)
and it is working nicely, and very quickly.
This is very cool and useful.


Trying something very similar, but on a production setup, so I don't
want to mess everything : Can I put a master storage domain into
maintenance mode, when it contains some running VMs?
Is yes, what will be the effect?
Will it only transfer the master metadata parts to another storage
domain, or will it also put it into read-only mode or other actions?

Thank you.



if the running VMs are from that storage domain, it shouldn't allow you 
to move it to maintenance (I hope)

[ovirt-users] Ubuntu/Debian support?

[Itamar Heim]

So, a quick non-scientific poll...

Motivation: It has been suggested that adding ubuntu or debian distro 
support could broaden the reach of the oVirt community.
To date, there has been some work towards this goal, but it is not 
coming to a conclusion.


Questions that comes to mind:

1) Is this still an issue?
2) Can we afford to dilute the focus we have as it is hard enough to
   stabilize the currently supported distro's? is it worth the
   potential impact?
3) Would it have maintainers catering to it so it won't be left behind
   / delay development?
4) Why bother with host support, ovirt-node can be used?
5) Why bother with engine support, a virtual appliance or a docker
   image could be used?
6) if we do it, should we focus on Ubuntu or Debian distro first?
7) if we do it, should we focus on host or engine first?

Thoughts?

Thanks,

oVirt seems to want to install a very old version of qemu, version 0.12.1 in
fact. Version 2.1.2 is now available. Is there any way to make oVirt use a
newer version or use/leave what’s already installed?



Hi John,
oVirt does not choose the qemu version. It uses the one available
in centos[1] or the other relevant distro repo.
Having that said, you need to bare in mind there's a whole stack build on top
of qemu (libvirt, vdsm, etc) and jumping forward may destabilize the setup
you're using.

you should also remember while the version did not change since the last 
distro rebase for .el6, it contains any feature ovirt/rhev is using via 
feature backports, so while its 0.12.1, it has way more advanced 
features in it.

E.g `rhevmcommand -lrt -p password `

Rhevmcommand is written in bash script, which internally calls REST api

Password is similar that of rhevm manager database.

Now I want something like

One question related to host reinstall vs yum update vdsm* comes into
my mind now..

On one of my all-in-one environments, which started from 3.0 days and
now is at 3.5 through progressive updates, I recently noticed some
*.rpmnew packages related to both engine and vdsm components.
I always updated the host part through yum update on this all-in-one
server.
This situation forced me to compare running .conf file vs .rpmnew ones
and to clean then the situation.

The question is: in general when you run reinstall host from engine
gui, does this process run a yum update and so you should care about
possible change in .conf files format, or does it go through
uninstall/install?


yum update

Re: [ovirt-users] Understanding Cluster / Datacenter upgrades

Hello,

I seem to have some issues understating what and when something happens
if I change a cluster or datacenter to a higher version after upgrading
engine.
Maybe somebody could help me understand how this works in general and
when features will get enabled? If possible, pinpoint it to concrete
features added in 3.5.

My assumptions learned form experience so far, upgrading oVirt 3.4 to
3.5; please correct if wrong:
- New features are enabled if I set the cluster compat version to a
newer version after upgrade


unless the features don't need a host change, so engine may just support 
them on your previous cluster level as well.

(or some even at host level upgrade)


- Prior to upgrading a datacenter all cluster need to run the higher
version (seems logical).


yes.


- This involves Engine database updates (?) and, more crucial, it will
change settings and data on the storage domains.


storage domains are only changed on DC upgrade, not cluster upgrade.


- Because of that, downgrade is not possible any more
- Also, its usually safer to keep the old cluster version while using a
newer engine version; because it is more likely to run into regressions
with an upgraded datacenter (see regression blockers for oVirt 3.5.1).

My questions so far:
- What happens if I only upgrade the cluster and *not* yet the datacenter?


you can use new features at host/cluster level (if any), but not DC 
level (storage usually, sometimes network) yet.



- In case of 3.5; exactly when could I have used the new NUMA
management? I assume after upgrading the cluster?


because its unrelated to storage, so its host or cluster level.


- In case of 3.5; exactly when could I have used the new QoS settings
(like disk profiles) - here I assume after upgrading the datacenter?


I think while these are storage, they only relate to VM behavior, not 
to storage domains, so cluster level sounds like the right level.

doron/allon?



If the the case of NUMA policy is not true but happens only after
upgrading the datacenter, what is the purpose of the cluster compat
version setting? I can think of making sure a certain minimum VDSM
version is running?


simply put:
host level (automatic) - engine may base some features on making sure
host has the right version

cluster level - features which require all hosts to have the new version 
to simplify things (we don't want to not be able to schedule a VM using 
a new feature only on some hosts, so we only allow them after cluster 
level upgrade.


dc level - since storage domains (mostly), and some network definitions, 
span multiple clusters, and for storage, all hosts in the DC may be 
asked to perform the new storage operations, hence DC level makes sure 
all hosts at DC level can do these actions.


and no, I don't have a mapping of which features require which...

You should keep the users list cc'ed so everybody with the same
questions can find the answers too :)

Well I never have seen lost vms in ovirt, but if you want to move
vms between storage domains afaik the only way to currently do so
is to export a vm from a data domain to an export domain and than
import from this export domain to another data domain.

export domains are basically nfs storage systems, so you want to make
sure your firewall and selinux settings are correct.

it's also possible to detach export domains, tar them
and then untar them in another ovirt einvironment and import
this whole export domain (use the -S flag if you have sparse vms!).

this should also be possible for data domains somehow:

http://www.ovirt.org/Features/ImportStorageDomain

but I didn't try this myself yet, so I don't know if this really
works yet (new features tend to need a point release until they
are matured enough ;) )

HTH



3.5 adds ability to see VMs on the domain not in the engine and add them 
(part of import domain).
not intended for lost vm's, except maybe after recovery of engine from 
old backup.

Hello,
now with oVirt 3.5 there is also iSCSI with NFS as backed
storage for
Hosted Engine.
What is the limitation about the storage domain? The integration in
setup scripts or due to storage type itself in engine mgmt?


Both ;) The storage is managed via vdsm so whatever vdsm supports HE
should support, but it requires some work in setup and the agent code.


What I mean is: if in some way one initially configures the
engine on an
external server (physical or virtual), could then be feasible
migrating
it manually in the oVirt environment (with backup/restore steps)?


- yes


Sorry,
do you mean that I can have a Gluster storage domain, with an external
engine and then backup/restore the egine inside a vm on this Gluster
environment as a self hosted engine?



we didn't add gluster due to concerns about how it works without replica 
3. we're looking with the gluster team around making sure this works 
together going forward

Hi,

I think this question did not get answered so far and I think this is a
crucial point. While it's cool you can integrate ovirt with openstack
I don't think it should be necessary when you want certain features.

Because, like Daniel wrote: Why should I install ovirt if I need
multiple openstack components anyway? I could just go on and deploy
openstack and not use ovirt?

But I also have the same opinion as Daniel: openstack ist too big
to deploy for traditional vm workloads.

So it would be much appreciated if this questions could get answered.


we are looking at integration in places we think they make sense and 
benefit ovirt by opening more options for users. we do try to provide 
the openstack services in a virtual appliance to make them easier to 
consume.

glance - image repo with a default glance.ovirt.org
neutron - for opening the ecosystem of SDN network solutions
   integrating with it
future: cinder - for opening the ecosystem of storage providers
   integrating with it.

I don't think currently the other services in openstack are relevant to 
ovirt.

not to use oVirt at all? ATM OpenStack seems to me like the literal
sledgehammer to crack a nut.

Hi,

I have some custom OS templates...how i can use my those OS template on my
another Ovirt Datacenter ??

I tried with export the template on another location and then try to add the
same NFS to another datacenter ...but can not add because of the data domain
already existsso i rename the nfs folder and create it and then move the
data under images from previous folder to new folderbut it didn't
workis there any way to copy or move the Templates and can use later on
the same datacenter or another datacenter ???

Thanks,
Punit



export the template to the export domain,
then move the export domain to maintenance and detach it from the current 
data-center.

now attach (import existing domain) the export domain to the new data-center, 
and activate (not sure if this happens automatically or not).
now you can import the template to the new  data-center,
if its the same ovirt setup, i assume you will need to select the 'clone' 
option and give it a new name

let me know if it helps

  Last week I upgraded to 3.5 and on the engine side everything went absolutely fine. Now I'm wondering what to do about my hosts (full CentOS 6

  Should I expect impact on running VM's, eg. from restarting vdsm?


 Looks like we have a documentation gap here.
 I tried to search the oVirt site for pointing you to a section
 describing how to upgrade hosts but did not found one.

 I think that we need to finish
 http://www.ovirt.org/DraftInstallationGuide
 and probably prepare an upgrade guide too.

 You'll need to install the ovirt-release35 rpm on your hosts
 since the engine is not able to add the new repository (yet?
 maybe an RFE on this should
 be filled for easing the upgrade process of the hosts).

i wasn't aware there is a nehalem without AES.
this causes libvirt to not identify/report any identified cpu, rather a

is this what you also get from 'vdsClient -s 0 getVdsCaps | grep cpu' ?

Re: [ovirt-users] ovirt-engine 3.5 rpm missing for el7

Hi,

The below response from Sandro on 12/08 in appears to answer the first
question:

  Is there any roadmap for supporting ovirt-engine on centos 7 ?

  It's not in 3.5 features so it will probably land in 3.6.

  You can install oVirt Hosted Engine on centos 7 host and use centos
6.5 for the engine VM only.

As to the second question – the above response implies that mixing el6
engine with el7 hosts with ovirt 3.5 is ok. However just to confirm, is
anyone running this combination and if so did you experience any major
issues or missing/broken functionality?

Cheers,

Chris Sullivan

Hi,

I’m testing hosted-engine v3.5.0 on el7 and it’s mostly progressing ok,
however when I go to install ovirt-engine 3.5 on the hosted engine VM
(also running el7) the rpm is missing. I’ve checked the repo locations
on resources.ovirt.org and it appears that ovirt-engine is not being
built for el7, whereas it exists for el6/f19/f20.

Are there plans to build ovirt-engine 3.5 for el7 or are there blockers
specific to that OS version? Alternatively, can I mix and el6 engine
with el7 hosts all running ovirt 3.5?


yes, an .el6 engine can manage .el7 hosts with 3.5

Re: [ovirt-users] [ovirt-devel] Building vdsm within Fedora

I don't belive Vdsm is soon to be used by anything outside oVirt. But if
software purists win, oVirt would publish only tarballs.
Fedora/Debian/whatever would build, package, and deploy them all, and
the ovirt repo would become redundant.

I did not expect to hear much support for keeping Vdsm in Fedora. Given
what I've heard, how about taking the in-between road?

- Keep Vdsm in Fedora, abiding to Fedora rules.
- Hope that Engine and qemu-kvm-rhev join, too.


we did the work to add engine, but it was useless without its gui, and 
was impossible to add gwt to fedora.
qemu-kvm-rhev is not needed in fedora as fedora has a full blown 
qemu-kvm with all features enabled.

you only need qemu-kvm-rhev on .el6 hosts.


- Until they do, build vdsm.rpm with non-Fedora quirks (such as the
   qemu-kvm-rhev requirement)
