[Michael Burman]

Hello Matt

Yes, there is a way, it can be done as part of our MultiHost Network
feature(since 3.4).
If you have the same logical network attached to multiple hosts in your DC,
you can update their vlan IDs via the 'Networks' main tab and this will
send a setup networks command through all of your hosts in the DC and
update the logical network with the new vlan ID.
- Note that this can be done when the VMs are running on the host/s as
well.

Good luck)

[ovirt-users] Two Problems On New Install

[Charles Tassell]

Hi Everyone,

  I recently installed oVirt 4.0 on two servers with an iSCSI 
backstore, and I'm having two issues I'm having trouble tracking down. 
First, the initial datastore that the hosted engine is running on won't 
connect.  It just says "Unattached" in the GUI, and I can't find an 
error message anywhere.  Not a huge deal, it just means I can't see the 
hosted engine itself in the GUI.


  More importantly: I can't migrate VMs.  They fail with errors like 
this in the vdsm.log of the destination host:


Thread-60381::ERROR::2017-02-14 
21:55:47,921::vm::767::virt.vm::(_startUnderlyingVm) 
vmId=`59f235cc-3ab2-4dae-b460-62be850e3d5d`::Failed to start a migration 
destination vm

raise MigrationError(e.get_error_message())
MigrationError: Domain not found: no domain with matching uuid 
'59f235cc-3ab2-4dae-b460-62be850e3d5d'


  If I shut the VM down and start it on the host it works fine, it just 
won't migrate.  I notice I'm also seeing a lot (like every 7 seconds) of 
this error:


JsonRpc (StompReactor)::ERROR::2017-02-14 
21:57:33,984::betterAsyncore::113::vds.dispatcher::(recv) SSL error 
during reading data: unexpected eof


  Which I can't seem to diagnose.  Any ideas?

[ovirt-users] Change Vlan ID's which are connected to the Host/VM's

[Matt .]

Hi Guys,

Is there a way to change Vlan ID's which are connected to the Hosts
when the VM's on it are down ?

As i need to change a lot of them it would be create if the engine can
perform some process which allows me to hammer my hosts with the new
vlan ID's for their bridges.

I hope someone has an idea.

Thanks!

If you're asking about VM conversion then the answer is no. virt-v2v
converts only to KVM, not the other way around.

If you're asking about the disks then the question is incorrect. The
right tool for this kind of operation is qemu-img. And yes, it can
convert from raw/QCow2 to VMDK.

Can virt-v2v convert back from ovirt format to VMware format?

just a quick update on the issue. The high amount of IOPS was

I think we already have hosted engine bug about doing to
many calls to vdsm
that cause reloads of lvm data; this can cause increased io.

Can you attach vdsm and hosted engine agent logs showing the
timeframe when
you have lot of iops on the server?

How many storages are you presenting to how many

Also, are your nodes all Hosted Engine Hosts? In my

Hi Andrea,

thanks for the insight; no I wasn't able to pinpoint
the issue to a single host, the load seems to be
evenly spread.
We have another cluster running 4.0.6 on a
compellent as well and we haven't experienced any
similar issues.

Hello Andrea,
I saw that happening on my HE hosts connected to

All HE hosts were hammering the SAN with 2~4k

Upgrading to 4.0.5 solved my case.
Are you able to check if IOPS are generated from
a particular host or rather spread among all nodes?

Hi,

We've got a 8-host cluster running oVirt 4.1;

Most of the VMs use barely any IOPS, however on

[ovirt-users] gdeploy error

[Ishmael Tsoaela]

Hi,


I am a new sys admin and trying to install glusterfs using gdeploy, I
started with a simple script to enable a service(ntpd).


 gdeploy --version
gdeploy 2.0.1

[root@ovirt1 gdeploy]# cat ntp.conf
[hosts]
ovirt1

[service1]
action=enable
service=ntpd

[service2]

The issue is that the gdeploy is returning error

Is there a simple way to debug or figure out how to fix this error?

It's not just disk format - imagine the network interface driver - the PV
Xen NIC driver vs. vmxnet3 (or however it's called) in VMware. Most of the
HW devices are different as well.

 Hi Andrea,

 thanks for the insight; no I wasn't able to pinpoint the issue to a
 single host, the load seems to be evenly spread.
 We have another cluster running 4.0.6 on a compellent as well and we
 haven't experienced any similar issues.

 Thanks,
 Andrea

OK, a bit of confusion here:
ovirt-hosted-engine-setup is going to create a VM for you based on
ovirt-engine-appliance (with the engine).
If you manually create a VM (L1) on your physical host (L0) to run
hosted-engine-setup there, hosted-engine-setup will create a VM (L2) for
the engine running inside the L1 VM and this requires nested virtualization
support which I think it's not enabled by default on oVirt hosts.
But the point is that you simply have to run ovirt-hosted-engine-setup on
your physical host and not on a VM otherwise all the HA mechanism of
hosted-engine will make no sense if nothing is bringing up your virtual
hosts for you.

hosted-engine-setup requires an host with no others running VMs so, if it's
already managed my an engine, move it to maintenance and remove it from
your cluster.

Yes, I assume it should be configured for virtualisation, since this
VM I'm creating to replace the bare-metal engine is running on one of
the two hosts that make up the cluster, and host 30 other running VMs
currently. Should it not run on the same cluster perhaps?

My steps are:

1. Create a VM on the cluster. Install the ovirt release rpm, install
the packages ovirt-hosted-engine-setup and ovirt-engine-appliance
2. run hosted-engine --deploy

...and that is as far as I have gotten so far.

Re: [ovirt-users] high number of IOPS from ovirt hosts

[Andrea Fagiani]

Hi,

just a quick update on the issue. The high amount of IOPS was indeed due 
to having the hosted-engine on the EQL storage; we worked around the 
issue by moving the hosted-engine to a gluster storage instead.


Thanks to everyone involved,
Andrea

Andrea, can you send also logs from ovirt-hosted-engine-ha?
(I'm not sure about the name of the service or the location of the logs)

I think we already have hosted engine bug about doing to many
calls to vdsm
that cause reloads of lvm data; this can cause increased io.

Can you attach vdsm and hosted engine agent logs showing the
timeframe when
you have lot of iops on the server?

Andrea,
I don't want to point any fingers but Mark Greenall faced
some issues with Ovirt 4.06/4.1 linked to equallogic as well.
You may want to search posts in this ML with subject "
Ovirt 4.0.6 guests 'Not Responding' " to see if you find
any similarities.
How many storages are you presenting to how many clusters?
Also, are your nodes all Hosted Engine Hosts? In my old
configuration, normal hosts read IOPS ranged from 50 to
500 while HE ones peaked even ~3000

Are you able to check if IOPS are generated from a
particular host or rather spread among all nodes?

Hi,

We've got a 8-host cluster running oVirt 4.1; each
host is connected via iscsi to a EQL 4100 storage (2x).
Most of the VMs use barely any IOPS, however on our
storage controller we've noticed a constant steam of
reads, about 2000 IOPS; any idea what might cause the
ovirt hosts to hammer on the storage so much?

Looking at iotop, it seems that systemd-udevd is
being activated every few seconds (and its IO% is
usually fairly high) so I assume this might be
somehow related.

Thanks,
Andrea

Is your CPU properly configured for virtualization? Are you running on a

Re: [ovirt-users] What is the libcacard-ev.x86_64 ??

Hello,
I reconnect to this thread, as I have similar problem/doubt relatd to
libcacard / libcacard-ev packages.
I had a cluster composed by two nodes, plain CentOS 7.3 nodes.
They were installed in 4.0.6 (on 21/01) and this involved installation of
libcacard-ev-2.3.0-31.el7.16.1.x86_64 package.
Then I updated to 4.1 (on 08/02) using "yum update" strategy and nothing
changed about this package.
Yesteray I added a third node, but I notice that on it I don't have
libcacard-ev but libcacard-2.5.2-2.el7.x86_64

Source for the -ev package is qemu-kvm-ev-2.3.0-31.el7.16.1.src.rpm and
build host el7-vm28.phx.ovirt.org and this makes me think it is the right
package.
But it is not pulled in into the new host where I think I have the standard
CentOS one with source RPM libcacard-2.5.2-2.el7.src.rpm and Packager
CentOS BuildSystem

The strange thing is that in their changelog I have:

- for standard libcacard:
* Fri Mar 18 2016 Miroslav Rezanina  - 2.5.2-2.el7
- Obsolete libcacard-rhev (bz#1315953)

* Fri Jan 29 2016 Miroslav Rezanina  - 2.5.2-1.el7
- Initial build

- for libcacard-ev
* Fri Jul 08 2016 Sandro Bonazzola  -
ev-2.3.0-31.el7_2.16.1
- Removing RH branding from package name

* Thu Jun 16 2016 Miroslav Rezanina  -
rhev-2.3.0-31.el7_2.16
- kvm-vga-add-sr_vbe-register-set.patch [bz#1347185]
- Resolves: bz#1347185
  (Regression from CVE-2016-3712: windows installer fails to start)
...

What to choose and to do?
Thanks,
Gianluca
