Are you running all-in-one with only this host or do you have more hosts
attached to this engine?
Is your data storage domain local? Or is it shared / provided by a
different host?

[ovirt-users] Ovirt-Log-Collector - Engine Crashes During Use

2017-12-21 Thread Langley, Robert

I'm working with a Red Hat Engineer (running oVirt 4.1.2 and transitioning to 
RHEV) and thought I would mention that while I'm trying to get logs for the 
engineer, the Engine crashes. First time was pretty quick. The second time, it 
notified me that it finished getting 2 of the 3 hypervisor logs. It seems like 
it crashed while trying to still get the 3rd hypervisor diag info/logs.

[ovirt-users] Q: oVirt and NFS / GlusterFS High-Availability File Sync Algorithm

2017-12-21 Thread Andrei V

Hi,

I would like to ask how (almost) high-availability file sync algorithm
works with very simple setup:
2-node (1 main and another backup) + engine on separate PC;
each node - Xeon server with RAID L5 for data domain.

With GlusterFS copy of each VM disk(s) is being stored on each node data
domain and kept up-to-date by GlusterFS sync process automatically.
How this works if data domains are on NFS data domains / volumes ?

My current setup is really simple, and don't need to be complicated any
further. 1st (main) node runs all the time, 2nd (backup) activated only
if 1st suffer for example a hardware failure. Anyway, both data domains
linked to 2 nodes must be kept fully synced.
Right now I finished setup only of 1st node (with CentOS 7, not oVirt
node appliance which wipes out all custom software changes upon
upgrade). Node data domain runs on GlusterFS.
Upon finishing setup of 2nd node (with GlusterFS) they will be joined as
Replica 2, and all VMs will be marked as highly available.

Since during normal operation all VM disks are being active only on one
node, and synced to 2nd (backup), I hope to avoid GlusterFS split brain
issue.

Please correct me if I'm wrong here. Quite possible I don't entirely
understand all underlying algorithms.

Thanks in advance
Andrei

In 4.2 we have a better OVN support which should definitively help there.
Why not write and share a small blog post with your oVirt on OVH hints?

Of course no replica with replica 1, but you could start like that then add
other 2 hosts in the future and gain replica 3 just with a little
reconfiguration and probably also without any downtime.

*- if not can anyone please help me to install atleast on one to make me
understand where am i doing the mistake.*
I'm using oVirt on a OVH's dedicated server. The bare metal works as host
and the engine is installed on a OVH's public cloud VM. I've also nested
three other oVirts inside the host.
Maybe i could help you , what's your issue? I'd put my money on OVH network
configuration :)


@Martin Sivak



*- one of the new features of oVirt 4.2 is support for Replica 1 all in one

Interesting. Maybe I don't understand it because I'm a newbie but...what's
the meaning of a replica 1 solution? I mean, if i have only one host
where's the replica?

Re: [ovirt-users] oVirt 4.2.0 is now generally available

2017-12-21 Thread Blaster


What a great Christmas present!

I'm still running 3.6.3 All-In-One configuration on Fedora 22.  So it 
looks like I'll be starting from scratch.


Is there any decent way yet to take my on disk VM images and easily 
attach them?  I put in an RFE for that which looks like it didn't make 
it into 4.2, now slated for 4.2.1.


The old way I used to do this was to create new VMs with new disks, then 
just copy over my old VMs to the disk files of the new VMs.  I'm 
assuming I'll still have to use that method.

Updates are often problematic.

Whenever someone manages to do a 4.1 to 4.2 upgrade could
possibility post it to the Wiki. That will help a lot of people.

Well, we did :-) Our infra is running on 4.2.0: 
https://engine-phx.ovirt.org/ovirt-engine/

We are keeping it updates since 3.4 every time we release.

Hi,
I have additional info on the problem. I run
/usr/share/ovirt-engine/setup/dbutils/fkvalidator.sh and the
problem is on 4 templates subversions. In detail we have two
templates and each one has two subversions.

Other templates with no subversions have no problem.

Thanks again, I hope this helps in debugging.

Thanks Giorgio, do you mind open a bug on

Re: [ovirt-users] Live migration without shared storage

2017-12-21 Thread FERNANDO FREDIANI

That is going certainly to be a very welcome feature and if not yet 
should be on the top of th roadmap. For planned maintenances it solves 
mostly all downtime problems.

We don't have shared storage and currently we are using XenServer

started looking into KVM as an alternative and decided to try ovirt. 
To our surprise KVM supports live migration without shared storage but 
ovirt does not.

OK, reproduced.
The issue happens if and only if you changed system wide locales after
having installed ovirt-engine but before upgrading it to 4.2.
I'm going to open a bug to track it.

In engine-setup we are explicitly setting en_US.UTF-8 as the locale of the
engine DB but we are not touching at all the locale of postgres own DB
which match the system wide locale and your issue is indeed on the postgres
DB, not on the engine one.
pg_upgrade cannot change it on the fly on upgrades.

I tried to find a working fix with env variables but unfortunately nothing
I tired worked.
The only workaround I was able to find is to temporary set the locale you
had at first successful engine-setup execution time (en_US.UTF-8 in your
case but it varies) under /etc/locale.conf and only then execute
engine-setup to upgrade it to 4.2.
After that you could safely switch back /etc/locale.conf to whatever you
need.
All the env variable I tried seams absolutely not relevant for this
specific issue.

2017-12-21 Thread Pujan Shah

We have a bit odd setup where some of our clients have dedicated hosts and
we also have some shared hosts. We can migrate client VMs from their
dedicated host to shared host if we need ot do some maintenance. We don't
have shared storage and currently we are using XenServer which supports
live migration without shared storage. We recently started looking into KVM
as an alternative and decided to try ovirt. To our surprise KVM supports
live migration without shared storage but ovirt does not. (
https://hgj.hu/live-migrating-a-virtual-machine-with-libvirt-without-a-shared-storage/)


I wanted to know if anyone has dealt with such situation and is this
something others are also looking for?

Pujan Shah

 Adding some people, I think one of your vms has an invalid

 saved in the db.

Sorry, previous mail started by mistake.
We have an upgrade guide which indeed needs some love:
https://ovirt.org/documentation/upgrade-guide/upgrade-guide/
But upgrade from 4.0 to 4.1 and 4.1 to 4.2 is not different, just different
ovirt-release rpm to be used.

Well, we did :-) Our infra is running on 4.2.0:

Seems an upgrade guide is more than needed for a 4.1 to 4.2 upgrade. 
Perhaps with all the feedback comming that can be done.

Re: [ovirt-users] Regarding Ovirt Installation

2017-12-21 Thread Martin Sivak

Hi,

one of the new features of oVirt 4.2 is support for Replica 1 all in
one setup using hosted engine and gluster in hyper-converged mode.

So it should be again possible to use just a single host for
everything, I am not sure we have a documentation ready for that
though.

Best regards

Martin Sivak

You could install Engine on a machine and re-use the same machine and
install it as a hypervisor. Apart from minor conflict between firewall
configurations, it should work.
See http://blog.domb.net/?p=2141 for such setup.

We don't have anymore an all-in-one installation where the engine and vdsm
runs altogether in the same machine; the proposed replacement is
hosted-engine which doesn't work with local storage since it's supposed to
be able to restart the engine VM somewhere else for HA reasons and the
local storage is against that by definition.
If you have three machines I'd suggest an hyperconverged gluster deployment
with replica 3.

If you want to try it on a single machine keep present that NFS in
loop-back is discouraged so maybe you could try iSCSI or, maybe with a
small hack, gluster in replica 1 in loopback

Re: [ovirt-users] Regarding Ovirt Installation

Hi,

if you bought a dedicated server with virtualization extensions
enabled you should have no problems.

Ask your provider if that extension is enabled. A friend of mine on
hetzner is using KVM without issues, but required some tweaks about
network that you can find in their docs.

Re: [ovirt-users] FC LUNs not detected

2017-12-21 Thread Nathanaël Blanchet


Have you choosed  the good datacenter/cluster/host?

What you see in the ui is the view from the selected host.

You may not have configured the lun to be available on the other ovirt 
hosts, and you chose one of these wrong hosts.


In every ways, you must make this lun available to all nodes of your 
cluster, otherwise, you won't be able to initiate your storage domain.

Whenever someone manages to do a 4.1 to 4.2 upgrade could possibility 
post it to the Wiki. That will help a lot of people.

[ovirt-users] missing vm in vm portal in statefull pool

2017-12-21 Thread Роман Черкалин

Hi all,

On ovirt 4.2 I make two pools 10 and 20 VMs, 1 vm for each user, and when 
overall number of vm more than 15 or so, on user login and start, VM has 
assigned but never appears in vm portal, if try to start again this message 
will be displayed:
"START_POOL failed [Cannot attach VM to VM-Pool. VM-Pool is already attached to 
a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User.,

Say if create one pool with 20 VM all happen again. Maybe I'm missing something?

[ovirt-users] Self hosted engine fails after 4.2 upgrade

2017-12-21 Thread Stefano Danzi


Hello!
I have a test system with one phisical host and hosted engine running on 
it.

Storage is gluster but hosted engine mount it as nfs.

After the upgrade gluster no longer activate nfs.
The command "gluster volume set engine nfs.disable off" doesn't help.

How I can re-enable nfs? O better how I can migrate self hosted engine 
to native glusterfs?

Re: [ovirt-users] Update to 4.2.0 failing in db check

2017-12-21 Thread Giorgio Biacchi


Hi,
I have additional info on the problem. I run 
/usr/share/ovirt-engine/setup/dbutils/fkvalidator.sh and the problem is on 4 
templates subversions. In detail we have two templates and each one has two 
subversions.


Other templates with no subversions have no problem.

Thanks again, I hope this helps in debugging.

Hello list,
I was about to upgrade from 4.1.8.2-1.el7.centos to 4.2.0 but
engine-setup fails. Here's the relevant output:

[ ERROR ] Failed to execute stage 'Setup validation': Failed checking

any ideas??


Adding some people, I think one of your vms has an invalid configuration
saved in the db.

Re: [ovirt-users] HA Broker fails after 4.2 upgrade

2017-12-21 Thread Martin Sivak

Btw lacking vdsm logs here this seems to be the same issue Jason
Brooks just reported here too. Hosted engine is trying to get storage
info from VDSM and gets error instead..

This simply means that the broker is not ready.
