Official Hyperconverged Gluster oVirt upgrade procedure?
by Hanson
Hi Guys,
Just wondering if we have an updated manual or whats the current
procedure for upgrading the nodes in a hyperconverged ovirt gluster pool?
Ie Nodes run 4.0 oVirt, as well as GlusterFS, and hosted-engine running
in a gluster storage domain.
Put node in maintenance mode and disable glusterfs from ovirt gui, run
yum update?
Thanks!

[vdsm] status update: running containers alongside VMs
by Francesco Romani
Hi everyone,
I'm happy to share some progress about the former "convirt"[1] project,
which aims to let Vdsm containers alongside VMs, on bare metal.
In the last couple of months I kept updating the patch series, which
is approaching the readiness to be merged in Vdsm.
Please read through this mail to see what the patchset can do now,
how you could try it *now*, even before it is merged.
Everyone is invited to share thoughts and ideas about how this effort
could evolve.
This will be a long mail; I will amend, enhance and polish the content
and make a blog post (on https://mojaves.github.io) to make it easier
to consume and to have some easy-to-find documentation. Later on the
same content will appear also on the oVirt blog.
Happy hacking!

# How to try how the experimental container support for Vdsm.
Vdsm is gaining *experimental* support to run containers alongside VMs.
Vdsm had since long time the ability to manage VMs which run containers,
and recently gained support for
[atomic guests](http://www.projectatomic.io/blog/2015/01/running-ovirt-guest-agent-as-privileged-container/).
With the new support we are describing, you will be able to manage containers
with the same, proven infrastructure that let you manage VMs.
This feature is currently being developed and it is still not merged in the
Vdsm codebase, so some extra work is needed if you want to try it out.
We aiming to merge it in the oVirt 4.1.z cycle.
## What works, aka what to expect
The basic features are expected to work:
1. Run any docker image on the public docker registry
2. Make the container accessible from the outside (aka not just from localhost)
3. Use file-based storage for persistent volumes
## What does not yet work, aka what NOT to expect
Few things are planned and currently under active development:
1. Monitoring. Engine will not get any update from the container besides "VM" status (Up, Down...)
One important drawback is that you will not be told the IP of the container from Engine,
you will need to connect to the Vdsm host to discover it using standard docker tools.
2. Proper network integration. Some steps still need manual intervention
3. Stability and recovery - it's pre-alpha software after all! :)
## 1. Introduction and prerequisites
Trying out container support affects only the host and the Vdsm.
Besides add few custom properties (totally safe and supported since early
3.z), there are zero changes required to the DB and to Engine.
Nevertheless, we recommend to dedicate one oVirt 4.y environment,
or at least one 4.y host, to try out the container feature.
To get started, first thing you need is to setup a vanilla oVirt 4.y
installation. We will need to make changes to the Vdsm and to the
Vdsm host, so hosted engine and/or oVirt node may add extra complexity,
better to avoid them at the moment.
The reminder of this tutorial assumes you are using two hosts,
one for Vdsm (will be changed) and one for Engine (will require zero changes);
furthermore, we assume the Vdsm host is running on CentOS 7.y.
We require:
- one test host for Vdsm. This host need to have one NIC dedicated to containers.
We will use the [docker macvlan driver](https://raesene.github.io/blog/2016/07/23/Docker-MacVLAN/),
so this NIC *must not be* part of one bridge.
- docker >= 1.12
- oVirt >= 4.0.5 (Vdsm >= 4.18.15)
- CentOS >= 7.2
Docker >= 1.12 is avaialable for download [here](https://docs.docker.com/engine/installation/linux/centos/)
Caveats:
1. docker from official rpms conflicts con docker from CentOS, and has a different package name: docker-engine vs docker.
Please note that the kubernetes package from CentOS, for example, require 'docker', not 'docker-engine'.
2. you may want to replace the default service file
[with this one](https://github.com/mojaves/convirt/blob/master/patches/centos72/syst...
and to use this
[sysconfig file](https://github.com/mojaves/convirt/blob/master/patches/centos72/sys....
Here I'm just adding the storage options docker requires, much like the CentOS docker is configured.
Configuring docker like this can save you some troubleshooting, especially if you had docker from CentOS installed
on the testing box.
## 2. Patch Vdsm to support containers
You need to patch and rebuild Vdsm.
Fetch [this patch](https://github.com/mojaves/convirt/blob/master/patches/vdsm/4.18.1...
and apply it against Vdsm 4.18.15.1. Vdsm 4.18.15.{1,2,...} are supported as well.
Rebuild Vdsm and reinstall on your box.
[centos 7.2 packages are here](https://github.com/mojaves/convirt/tree/master/rpms/centos72)
Make sure you install the Vdsm command line client (vdsm-cli)
Restart *both* Vdsm and Supervdsm, make sure Engine still works flawlessly with patched Vdsm.
This ensure that no regression is introduced, and that your environment can run VMs just as before.
Now we can proceed adding the container support.
start docker:
# systemctl start docker-engine
(optional)
# systemctl enable docker-engine
Restart Vdsm again
# systemctl restart vdsm
Now we can check if Vdsm detects docker, so you can use it:
still on the same Vdsm host, run
$ vdsClient -s 0 getVdsCaps | grep containers
containers = ['docker', 'fake']
This means this Vdsm can run containers using 'docker' and 'fake' runtimes.
Ignore the 'fake' runtime; as the name suggests, is a test driver, kinda like /dev/null.
Now we need to make sure the host network configuration is fine.
### 2.1. Configure the docker network for Vdsm
PLEASE NOTE
that the suggested network configuration assumes that
* you have one network, `ovirtmgmt` (the default one) you use for everything
* you have one Vdsm host with at least two NICs, one bound to the `ovirtmgmt` network, and one spare
_This step is not yet automated by Vdsm_, so manual action is needed; Vdsm will take
care of this automatically in the future.
You can use
[this helper script](https://github.com/mojaves/convirt/blob/master/patches/vdsm/cont-...,
which reuses the Vdsm libraries. Make sure
you have patched Vdsm to support container before to use it.
Let's review what the script needs:
# ./cont-setup-net -h
usage: cont-setup-net [-h] [--name [NAME]] [--bridge [BRIDGE]]
[--interface [INTERFACE]] [--gateway [GATEWAY]]
[--subnet [SUBNET]] [--mask [MASK]]
optional arguments:
-h, --help show this help message and exit
--name [NAME] network name to use
--bridge [BRIDGE] bridge to use
--interface [INTERFACE]
interface to use
--gateway [GATEWAY] address of the gateway
--subnet [SUBNET] subnet to use
--mask [MASK] netmask to use
So we need to feed --name, --interface, --gateway, --subnet and optionally --mask (default, /24, is often fine).
For my case the default mask was indeed fine, so I used the script like this:
# ./cont-setup-net --name ovirtmgmt --interface enp3s0 --gateway 192.168.1.1 --subnet 192.168.1.0
Thhis is the output I got:
DEBUG:virt.containers.runtime:configuring runtime 'docker'
DEBUG:virt.containers.command:* calling ['/bin/docker', 'network', 'inspect', 'ovirtmgmt']
Error: No such network: ovirtmgmt
DEBUG:virt.containers.command:* called ['/bin/docker', 'network', 'inspect', 'ovirtmgmt']
DEBUG:virt.containers.runtime.Docker:config: cannot load 'ovirtmgmt', ignored
DEBUG:virt.containers.command:* calling ['/bin/docker', 'network', 'create', '-d', 'macvlan', '--subnet=192.168.1.0/24', '--gateway=192.168.1.1', '--ip-range=192.168.1.0/24', '-o', 'parent=enp3s0', 'ovirtmgmt']
DEBUG:virt.containers.command:* called ['/bin/docker', 'network', 'create', '-d', 'macvlan', '--subnet=192.168.1.0/24', '--gateway=192.168.1.1', '--ip-range=192.168.1.0/24', '-o', 'parent=enp3s0', 'ovirtmgmt']
DEBUG:virt.containers.runtime:configuring runtime 'fake'
You can clearly see what the script did, and why it needed the root privileges. Let's deoublecheck using the docker tools:
# docker network ls
NETWORK ID NAME DRIVER SCOPE
91535f3425a8 bridge bridge local
d42f7e5561b5 host host local
621ab6dd49b1 none null local
f4b88e4a67eb ovirtmgmt macvlan local
# docker network inspect ovirtmgmt
[
{
"Name": "ovirtmgmt",
"Id": "f4b88e4a67ebb7886ec74073333d613b1893272530cae4d407c95ab587c5fea1",
"Scope": "local",
"Driver": "macvlan",
"EnableIPv6": false,
"IPAM": {
"Driver": "default",
"Options": {},
"Config": [
{
"Subnet": "192.168.1.0/24",
"IPRange": "192.168.1.0/24",
"Gateway": "192.168.1.1"
}
]
},
"Internal": false,
"Containers": {},
"Options": {
"parent": "enp3s0"
},
"Labels": {}
}
]
Looks good! the host configuration is completed. Let's move to the Engine side.
## 3. Configure Engine
As mentioned above, we need now to configure Engine. This boils down to:
Add a few custom properties for VMs:
In case you were already using custom properties, you need to amend the command
line to not overwrite your existing ones.
# engine-config -s UserDefinedVMProperties='volumeMap=^[a-zA-Z_-]+:[a-zA-Z_-]+$;containerImage=^[a-zA-Z]+(://|)[a-zA-Z]+$;containerType=^(docker|rkt)$' --cver=4.0
It is worth stressing that while the variables are container-specific,
the VM custom properties are totally inuntrusive and old concept in oVirt, so
this step is totally safe.
Now restart Engine to let it use the new variables:
# systemctl restart ovirt-engine
The next step is actually configure one "container VM" and run it.
## 4. Create the container "VM"
To finally run a container, you start creating a VM much like you always did, with
few changes
1. most of the hardware-related configuration isn't relevant for container "VMs",
besides cpu share and memory limits; this will be better documented in the
future; unneeded configuration will just be ignored
2. You need to set some custom properties for your container "VM". Those are
actually needed to enable the container flow, and they are documented in
the next section. You *need* to set at least `containerType` and `containerImage`.
### 4.2. Custom variables for container support
The container support needs some custom properties to be properly configured:
1. `containerImage` (*needed* to enable the container system).
Just select the target image you want to run. You can use the standard syntax of the
container runtimes.
2. `containerType` (*needed* to enable the container system).
Selects the container runtime you want to use. All the available options are always showed.
Please note that unavailable container options are not yet grayed out.
If you *do not* have rkt support on your host, you still can select it, but it won't work.
3. `volumeMap` key:value like. You can map one "VM" disk (key) to one container volume (value),
to have persistent storage. Only file-based storage is supported.
Example configuration:
`containerImage = redis`
`containerType = docker`
`volumeMap = vda:data` (this may not be needed, and the volume label is just for illustrative purposes)
### 4.2. A little bit of extra work: preload the images on the Vdsm host
This step is not needed by the flow, and will be handled by oVirt in the future.
The issue is how the container image are handled. They are stored by the container
management system (rkt, docker) on each host, and they are not pre-downloaded.
To shorten the duration of the first boot, you are advised to pre-download
the image(s) you want to run. For example
## on the Vdsm host you want to use with containers
# docker pull redis
## 5. Run the container "VM"
You are now all set to run your "VM" using oVirt Engine, just like any existing VM.
Some actions doesn't make sense for a container "VM", like live migration.
Engine won't stop you to try to do those actions, but they will fail gracefully
using the standard errors.
## 6. Next steps
What to expect from this project in the future?
For the integration with Vdsm, we want to fix the existing known issues, most notably:
* add proper monitoring/reporting of the container health
* ensure proper integration of the container image store with oVirt storage management
* streamline the network configuration
What is explicitely excluded yet is any Engine change. This is a Vdsm-only change at the
moment, so fixing the following is currently unplanned:
* First and foremost, Engine will not distinguish between real VMs and container VMs.
Actions unavailable to container will not be hidden from UI. Same for monitoring
and configuration data, which will be ignored.
* Engine is NOT aware of the volumes one container can use. You must inspect and do the
mapping manually.
* Engine is NOT aware of the available container runtimes. You must select it carefully
Proper integration with Engine may be added in the future once this feature exits
from the experimental/provisional stage.
Thanks for reading, make sure to share your thoughts on the oVirt mailing lists!

[1] we keep calling it that way _only_ internally, because it's a short
name we are used to. After the merge/once we release it, we will use
a different name, like "vdsm-containers" or something like it.

I don't think I ever replied to this, but I can confirm that in RHEV 3.6
it works with NFS.

Lowering the bar for wiki contribution?
by Roy Golan
I'm getting the feeling I'm not alone in this, authoring and publishing a
wiki page isn't as used to be for long time.
I want to suggest a bit lighter workflow:
1. Everyone can merge their page - (it's a wiki)
Same as with (public and open) code, no one has the motivation to publish
a badly written
wiki page under their name. True, it can have an impact, but not as with
broken code
2. Use Page-Status marker
The author first merges the draft. Its now out there and should be updated
as time goes and its
status is DRAFT. Maintainers will come later and after review would change
the status to
PUBLISH. That could be a header in on the page:
---
page status: DRAFT/PUBLISH
---
Simple I think, and should work.

Hello,
In oVirt 4.1 web admin gui I see events about users logging out (they have
been created on internal domain with ovirt-aaa-jdbc-tool command), but I
don't see the corresponding log in event.
The same is true for the default admin@internal user.
Is there any reason or is it a bug?

ovirt-ha-agent cpu usage
by Gianluca Cecchi
Hello,
I have a test machine that is a nuc6 with an i5 and 32G of ram and SSD
disks.
It is configured as a single host environment with Self Hosted Engine VM.
Both host and SHE are CentOS 7.2 and oVirt version is 3.6.6.2-1.el7
I notice that having 3 VMs powered on and making nothing special (engine
VM, a CentOS 7 VM and a Fedora 24 VM) the ovirt-ha-agent process on host
often spikes its cpu usage.
See for example this quick video with top command running on host that
reflects what happens continuously.
https://drive.google.com/file/d/0BwoPbcrMv8mvYUVRMFlLVmxRdXM/view?usp=sha...
Is it normal that ovirt-ha-agent consumes all this amount of cpu?
Going into /var/log/ovirt-hosted-engine-ha/agent.log I see nothing special,
only messages of type "INFO". The same for broker.log
Thanks,
Gianluca

Hosted engine Single Sign-On to VM with freeIPA not working

Hi,
I am having an issue with getting SSO to work when a standard user(UserRole)
logs in to the UserPortal.
The user has permission to use only this VM, so after login the console is
automatically opened for that VM.
Problem is that it doesn't login on the VM system with the provided
credentials. Manual login at the console works without any issues.
HBAC-rule check on IPA shows access is granted. Client has SELINUX in
permissive mode and a disabled firewalld.
On the client side I do see some PAM related errors in the logs (see details
below). Extensive Google search on error 17 "Failure setting user
credentials" didn't show helpful information :-(
AFAIK this is did a pretty standard set-up, all working with RH-family
products. I would expect others to encounter this issue as well.
If someone knows any solution or has some directions to fix this it would be
greatly appreciated.
Thanks,
Paul
------------------------------------------------------
System setup: I have 3 systems
The connection between the Engine and IPA is working fine. (I can log in
with IPA users etc.) Connection is made according to this document:

VM has been paused due to storage I/O problem
by Gianluca Cecchi
Hello,
my test environment is composed by 2 old HP blades BL685c G1 (ovmsrv05 and
ovmsrv06) and they are connected in a SAN with FC-switches to an old IBM
DS4700 storage array.
Apart from being old, they seem all ok from an hw point of view.
I have configured oVirt 4.0.6 and an FCP storage domain.
The hosts are plain CentOS 7.3 servers fully updated.
It is not an hosted engine environment: the manager is a vm outside of the
cluster.
I have configured power mgmt on both and it works good.
I have at the moment only one VM for test and it is doing quite nothing.
Starting point: ovmsrv05 is in maintenance (since about 2 days) and the VM
is running on ovmsrv06.
I update qemu-kvm package on ovmsrv05 and then I restart it from web admin
gui:
Power Mgmt --> Restart
Sequence of events in pane and the problem in subject:

Watching the timestamps, the culprit seems the reboot time of ovmsrv05 that
detects some LUNs in owned state and other ones in unowned
Full messages of both hosts here:
https://drive.google.com/file/d/0BwoPbcrMv8mvekZQT1pjc0NMRlU/view?usp=sha...
and
https://drive.google.com/file/d/0BwoPbcrMv8mvcjBCYVdFZWdXTms/view?usp=sha...
At this time there are 4 LUNs globally seen by the two hosts but only 1 of
them is currently configured as the only storage domain in oVirt cluster.

I don't know exactly the meaning of owned/unowned in the output above..
Possibly it detects the 0:0:1:3 and 2:0:1:3 paths (those of the active
group) as "owned" and this could have created problems with the active node?
On active node strangely I don't loose all the paths, but the VM has been
paused anyway

I'm not an expert of this storage array in particular, and of the rdac
hardware handler in general.
What I see is that multipath.conf on both nodes:
# VDSM REVISION 1.3
defaults {
polling_interval 5
no_path_retry fail
user_friendly_names no
flush_on_last_del yes
fast_io_fail_tmo 5
dev_loss_tmo 30
max_fds 4096
}
devices {
device {
# These settings overrides built-in devices settings. It does not
apply
# to devices without built-in settings (these use the settings in
the
# "defaults" section), or to devices defined in the "devices"
section.
# Note: This is not available yet on Fedora 21. For more info see
# https://bugzilla.redhat.com/1253799
all_devs yes
no_path_retry fail
}
}
beginning of /proc/scsi/scsi

Any hint on how to tune multipath.conf so that a powering on server doesn't
create problems to running VMs?
Thanks in advance,
