I am working on KubeVirt. I can't tell you how the integration in oVirt
works in detail and which capabilities you inherit from normal RHV flows,
but I can tell you a little bit about this from the kubevirt and openshift
perspective.
I think that you will need a bunch of openshift clusters (10+) to cope with
that number of VMs/Pods. Also keep in mind that you will have to use for
VDI something like citrix, windows remote desktop or so on. KubeVirt does
not support spice, just in case that this was your target.

Others can probably tell you more.

Best Regards,
Roman

Yaniv Bronheim mostly worked on it when the repo was moved to oVirt.

Sandro,  Simone, since he is now working on other things, do you guys
know anything about plans for updating the repo?

Note that latest fakevdsm is currently broken when using it with 4.0
releases, it only works on master.

You can check out the code from here

https://gerrit.ovirt.org/#/c/65333/

to get a working version for 4.0.

could you try running "mvn clean" before starting it again? Fakevdsm has a
cache and if something is wrong with that data there (e.g. a bug or
switching between engine versions) you can end up in such situations.
Running "mvn clean" cleans the cache too.

Thanks.

The bug is here: https://bugzilla.redhat.com/show_bug.cgi?id=1349745.

I thought about the solution and I see one possible problem with this
approach. It might be that the engine still thinks that the VM is on
the old cluster.
Let me know if this happens, we can work around that too.

That is correct, only the he-agents on each host decide where the
hosted engine VM can start

Also true, it is very limited what you can currently do with the
hosted engine VM.

That is indeed something the InClusterUpgrade does not take into
consideration. I will file a bug report.

 But what you can do is the following:

You can create a temporary cluster, move one host and the hosted
engine VM there, upgrade all hosts and then start the hosted-engine VM
in the original cluster again.

The detailed steps are:

1) Enter the global maintenance mode
2) Create a temporary cluster
3) Put one of the hosted engine hosts which does not currently host
the engine into maintenance
4) Move this host to the temporary cluster
5) Stop the hosted-engine-vm with `hosted-engine --destroy-vm` (it
should not come up again since you are in maintenance mode)
6) Start the hosted-egine-vm with `hosted-engine --start-vm` on the
host in the temporary cluster
7) Now you can enable the InClusterUpgrade policy on your main cluster
7) Proceed with your main cluster like described in
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Self-Hosted_Engine_Guide/Upgrading_the_Self-Hosted_Engine_from_6_to_7.html
8) When all hosts are upgraded and InClusterUpgrade policy is disabled
again, move the hosted-engine-vm back to the original cluster
9) Upgrade the last host
10) Migrate the last host back
11) Delete the temporary cluster
12) Deactivate maintenance mode

Adding Sandro and Roy to keep me honest.

You have to do a "force remove" in the UI (without clicking the
destroy checkbox) of that storage. Then it should be reimported
automatically.

I am not sure what will happen with the imported hosted engine storage
domain in ovirt-engine. It might still show the old path in the UI.
Adding Roy.
For me the steps look good but I never did it. Adding Martin and Simone.

[ovirt-users] Monitor your oVirt datacenter with Prometheus

2016-04-13 Thread Roman Mohr
Hi,

I created a blogpost on how to monitor your oVirt datacenter with
Prometheus [1].

This way you get access to real time metrics and can use the powerful
Prometheus query language, the Prometheus Alertmanager and visualization
tools like Grafana.

Tasks like finding hosts which are underutilized, finding VMs which are not
behaving or even comparing resource usage profiles of whole cluster over
days become only a matter of writing the right Prometheus query. Further
you can use the Prometheus Alertmanager for alerting.

An example which is also part of the post [1]: Visualizing the sum of the
CPU usage of all VMs for ever host is as simple as

sum(vm_cpu_user) by (host).

To close the gap between oVirt Engine and Prometheus I had to create two
services vdsm-prometheus (github[2], docker hub[3]) and
ovirt-prometheus-bridge (github[4], copr[5]).

An ansible role [6] to roll out vdsm-prometheus to all oVirt 3.5 or 3.6
hosts exists too.

So make sure to checkout the post [1] and let me know if you find this
useful.

Best Regards,
Roman

Just a guess, but could it be that the installed Windows onlhy
supports 4 processors [1]?

If not, could you share the domain xml of the running VM?

Oh I missed that. When that is configured correctly, as @Simone already

did you try to right click on the faulty host and click "confirm host has
been rebooted"? This might help.
Probably you have the situation described in [1], question 19.

Could you check if you see the file /etc/ovirt-hosted-engine/answers.conf
on the host where you want to copy the answer file from?
If not, most likely something went wrong when you set up the first node.
You will find your ansers file then in this
/var/lib/ovirt-hosted-engine-setup/answers/ folder.

You might find some errors in
/var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine*.log on the first
node. Could you provide the log from this node?

After copying the ansers file from
/var/lib/ovirt-hosted-engine-setup/answers/ over to
/etc/ovirt-hosted-engine/answers.conf you should no longer see this error
on the other hosts.

You should only be affected by that bug if you see something like

No such file or directory:
'/rhev/data-center/mnt/[...]/ha_agent/hosted-engine.metadata.

This is related to accessing metadata of other nodes through the storage
mounted by vdsm.

Did you install the gurest agent [1] on the VMs? This information is
collected from within the VM.

   This doesn't seem to affect any operation.   Why would this be?

Re: [ovirt-users] oVirt monitoring with libirt-snmp

2015-10-21 Thread Roman Mohr
Hi Kevin,


you should not change auth_unix_rw=sasl. I never used libvirt-snmp but it
is save to create another user like this:

> saslpasswd2 -a libvirt 

I did that several times on my hosts.
