It would be useful to understand the errors you get in web ui, because they
could be similar also in command line deploy

I think you can follow what happened in 3.6 as described here:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Self-Hosted_Engine_Guide/chap-Installing_Additional_Hosts_to_a_Self-Hosted_Environment.html

For oVirt and CentOS I think that these below should be the commands to run
on your second host (see the other details explained in the web page above,
that could be different in some way in 4.0 vs 3.6)

# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm
# yum install ovirt-hosted-engine-setup
# hosted-engine --deploy

HIH,
Gianluca

Re: [ovirt-users] Can't connect to my VMs' consoles using any method

[summit hainey]

I believe I have setup the engine as a proxy, during the initial install, 
unless I'm remembering incorrectly, or misread something.

I ended up at least being able to connect using the "Native" client option, 
apparently, the TLS port was not being forwarded by default in the firewall 
settings oVirt setup during install. I got the console to work after opening 
the port and saving the .vv, and then running it manually, however this is not 
a good long term solution for my situation... ideally I'd like to get one or 
both of the browser clients working.


I think the issue may be one of three things, a cert issue, but I don't know 
how likely that is. Obviously I get an invalid cert issue from whatever browser 
I access oVirt with since it's just using the default local certs, but I've 
allowed them on both Firefox and Chromium, and I've gotten a websocket console 
to work in different management platforms (kimchi), however I read somewhere in 
my search that oVirt uses two certs, one for the main part of the client, and 
then another for websockets, however I don't know if this is accurate.

The other thing I suspect is that it could be another port/firewall related 
issue, although I cannot see what port it could be, and I have no real hints to 
go on.


Lastly I imagine the proxy could be ill-configured, but I don't know how seeing 
as everything is essentially set to default.

Actually, I just thought of another possibility though it seems like a bit of a 
stretch, but I'm running the oVirt host and the engine on the same machine, but 
not in a hosted-engine setup.

That's the best I've got, though.___

Why do you have 1 SD per VM?

Can you try and disable (mask) the lvmetad service on the hosts and see if
it improves matters?
Also /var/log/messages from the host may give us some clues.
TIA,
Y.

Today I had a similar problem. The time between the new host and the

[ovirt-users] Hosted Engine: Add another host

[gregor]

Hi,

I have a hosted-engine setup on one host. Today I try to add another
host from the UI but this gives me some errors without detail.

Is there a way to add a new host from the shell?
Not a node [1] because I plan to use docker as well on the host, it's a
test environment.
Or is it better to install the host as node?

cheers

A new oVirt Next Generation Node is now available[2].
If you update oVirt Next Generation Node you'll receive 4.0.6.1 image build
since we had to respin it due to a problem in the build we delivered
yesterday (wrong vdsm version included within the image).

I do thin it is. We are involved in the tooling, for their maintenance,
for documenting where things are, for suggesting better solutions,
ensuring security…

As for code, I think there is need for review, even more for design
documents, so I don't see why people are bothered by PRs, which is a
tool they already know fairly well.

For people with few git knowledge, the GitHub web interface allows to
edit files.

Yes, this official entry point and it needs to be clean.

We could indeed split the technical documentation. If people want to
experiment with the GH wiki pages, I won't interfere.

I read several people in this thread really miss the old wiki, so I
think it is time to remember why we did not stay in paradise. I was not
there at the time, but I know the wiki was not well maintained. People
are comparing our situation to the MediaWiki site, but the workforce is
nowhere to be compared. There is already no community manager, and noone
is in charge of any part really, whereas Mediawiki has people in charge
of every corner of the wiki. Also they developed tools over years to
monitor, correct, revert… and we don't have any of this. So without any
process then it was a total mess. More than one year later there was
still much cleanup to do, and having contributed to it a little bit, I
fear a sentimental rush to go back to a solution that was abandoned.

Having a header telling if this is a draft or published is far from
being sufficient. If noone cares you just pile up content that gets
obsolete, then useless, then misleading for newcomers. You may prefer
review a posteriori, but in this case you need to have the proper tool
to be able to search for things to be reviewed, and a in-content
pseudo-header is really not an easy way to get a todolist.

As for the current builder, it checks every minute for new content to
build. The current tool (Middleman) is a bit slow, and the machine is
not ultra speedy, but even in the worst case it should not take more
than half an hour to see the published result. So I don't know why
someone suggested to build "at least once a day". There is also an
experimentation to improve this part.

So to sum up:
  - the most needed thing here is not a tool but people in charge to
review the content (additions, cleanup old things, ask devs to update
some missing part…), this should also allow for faster publishing
  - I'm not against changing tool, just do not forget what you loose in
the process, and the migration pain
  - I think free editing without workflow in our specific case is not
gonna work because we do not have the needed workforce for things to
auto-correct

Mirrors are currently outdated, I guess they need more time to sync.
In the meanwhile you can uncomment the baseurl line in the .repo file and
comment the mirrorlist line to be sure you get latest repo content.

Re: [ovirt-users] Specifying the datastore on a VmPool creation via Python-SDK?

[nicolas]

Any ideas to this?

El 2017-01-10 08:43, nico...@devels.es escribió:

Hi,

We've several templates that have their disks replicated (copied) on
all our Storage Domains. Problem is that we create our VmPools using
PythonSDK, and it usually creates the pool on one of our Storage
Domains that has a small amount of free disk space.

Some of the Data Stores have plenty of space and when creating the
VmPool, we'd like to be able to specify on which of these Storage
Domains to create the VmPool. So far I see no parameter on the
params.VmPool class to do that. I've tried using an Action, but the
request is not correct:

  action = 
params.Action(storage_domain=api.storagedomains.get(name='...'))


  pool = params.VmPool(name='testlarge',
cluster=api.clusters.get(name='...'),
template=api.templates.get(name='Blank'), max_user_vms=1, size=1,
type_='manual', actions=action)
  pool = params.VmPool(name='testlarge',
cluster=api.clusters.get(name='...'),
template=api.templates.get(name='Blank'), max_user_vms=1, size=1,
type_='manual', actions=[action])

  api.vmpools.add(pool)

Both tries fail.

This is Python-SDK 3.x.

Is there a way to specify the destination Storage Domain onto where to
create the VmPool?

Thanks

Re: [ovirt-users] Max number of api calls per user?

[Grundmann, Christian]

@ What does 'simultaneously' mean exactly? Are you sending the requests in
parallel from different threads? Or from different processes? Or just
sending them in a loop?

I call the python script multiple times for different VMs from different
shells.

@ The /var/log/ovirt-engine/server.log, /var/log/ovirt-engine/engine.log and
/var/log/httpd/ssl_access_log files can help determine what is happening.
Can you check and maybe share the relevant part of those files?

Running yum clean does not have any effect.  Is there an issue with the

What does 'simultaneously' mean exactly? Are you sending the requests in
parallel from different threads? Or from different processes? Or just
sending them in a loop?

The /var/log/ovirt-engine/server.log, /var/log/ovirt-engine/engine.log
and /var/log/httpd/ssl_access_log files can help determine what is
happening. Can you check and maybe share the relevant part of those files?

[ovirt-users] Max number of api calls per user?

[Grundmann, Christian]

Hi,

is there a maximum number of sessions per user?

 

I am doing python-api calls to remove VMs

If I call my script 30 times simultaneously, one or two get an error.

 

Traceback (most recent call last):
  File "remove_vm.py", line 24, in 
if VMNAME in [vm.name for vm in api.vms.list()]:
  File
"/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/brokers.py", line
35761, in list
headers={"All-Content":all_content}
  File "/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/proxy.py",
line 46, in get
return self.request(method='GET', url=url, headers=headers, cls=cls)
  File "/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/proxy.py",
line 122, in request
persistent_auth=self.__persistent_auth
  File
"/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/connectionspool.py
", line 79, in do_request
persistent_auth)
  File
"/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/connectionspool.py
", line 162, in __do_request
raise errors.RequestError(response_code, response_reason, response_body)
ovirtsdk.infrastructure.errors.RequestError: 
status: 401
reason: Unauthorized
detail: User is not logged in.

 

 

Is there some setting I can tune?

 

Thx Christian

 This option opens a dialog, with a lateral menu of tabs. one of those
 tabs is "MAC Address Pools". just go there and add your new range.

Re: [ovirt-users] Not Enough Mac address pool

[Michael Burman]

Hi Budur

On 3.5 you should increase or create the MAC pool range via the
engine-config:

Example:
engine-config -s MacPoolRanges=00:00:00:00:00:00-FF:FF:FF:FF:FF:FF
restart engine service

Good luck

It seems that you (or any other administrator) configured the engine to use a 
specific range of mac addresses for your virtual machines, and this range was 
not enough for the number of vms you want to use. you need to add a new range 
of mac addresses or expand the existing one, if possible. You can find this 
settings on the "Configure" menu, right top of ovirt engine admin portal, if 
you have the required permissions.

Re: [ovirt-users] Leaving maintenace mode

[Martin Sivak]

Hi,

we will focus on this exact issue (and couple of similar ones) in the
next release, but the reason is actually pretty simple.. the ISO
domain is mounted to the /rhev space and a when a simple traversal
hits the unavailable NFS ISO domain, it gets stuck.. and the timeout
is somewhat long.

node-ng should have vdsm-4.18.21-1.el7.centos.noarch; I fear that the build
job took outdated mirrors to make the compose.
I'm going to re-trigger the build and re-publish it today.
In the meanwhile, yum update should let you update vdsm within the node
host.
I'm sorry for the issue.

Re: [ovirt-users] [ANN] oVirt 4.0.6 Release is now available

[Grundmann, Christian]

Hi,
Release Nodes showing “BZ 1374988 MOM 
causes Vdsm to slow down, high number of 'vmGetIoTunePolicy' API calls – vdsm “
Bugzilla shows “Target Release:   4.18.16”

yum update ovirt-node-ng-image gave me ovirt-node-ng-image-4.0.6-1.el7
which installs vdsm-4.18.15.3-1

Is it fixed or not?


Thx Christian

I don't have at hand a rhel 5.8 iso but I reproduced the same problem with rhel

I verified that in edit VM, console, the only "Video Type" option that works is 
"Cirrus", while with QXL and VGA I get the same problem described by you.
I think you can install in graphic mode with Cirrus video type and then setup 
the operating system for QXL in a second time, also taking in account what 
detailed in this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=890230
(or keep Cirrus+VNC graphical access also after install)

In effect it is strange.
Inside official docs for RHEV 4.0 we have:
Administration Guide
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/administration-guide/52-cluster-tasks

"
5.2.2.2. Optimization Settings Explained
Memory Balloon
Selecting the Enable Memory Balloon
Optimization check box enables memory
overcommitment on virtual machines running
on the hosts in this cluster. When this option
is set, the Memory Overcommit Manager
(MoM) will start ballooning where and when
possible, with a limitation of the guaranteed
memory size of every virtual machine.
...
It is important to understand that in some
scenarios ballooning may collide with KSM. In
such cases MoM will try to adjust the balloon
size to minimize collisions. Additionally, in
some scenarios ballooning may cause sub-
optimal performance for a virtual machine.
Administrators are advised to use ballooning
optimization with caution.
"

So it seems it is indeed possible to enable ballooning (note the
considerations about KSM that could partially answer to your question...)

But then in Virtual Machine Management Guide here
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/virtual-machine-management-guide/33-installing-guest-agents-and-drivers

I see
"
3.3.1. Red Hat Virtualization Guest Agents and Drivers

virtio-balloon

Virtio-balloon is used to
control the amount of
memory a guest actually
accesses. It offers improved
memory over-commitment.
The balloon drivers are
installed for future
compatibility but not used by
default in Red Hat
Virtualization.
"

So it seems it is not possible to enable it for guests
Any clarification?

Thanks,
Gianluca
