Hello,
=20
last Wednesday I wanted to update my oVirt 3.5 hypervisor. It is a =
single Centos 7 server, so I started by suspending the VMs in order to =
set the oVirt engine host to maintenance mode. During the process of =
suspending the VMs the server crashed, kernel panic=E2=80=A6
After restarting the server I installed the updates via yum an restarted =
the server again. Afterwards, all the VMs could be started again. Some =
hours later my monitoring system registered some unresponsive hosts, I =
had a look in the oVirt interface, 3 of the VMs were in the state =
=E2=80=9Cnot responding=E2=80=9D, marked by a question mark.=20
I tried to shut down the VMs, but oVirt wasn=E2=80=99t able to do so. I =
tried to reset the status in the database with the sql statement
=20
update vm_dynamic set status =3D 0 where vm_guid =3D (select vm_guid =
from vm_static where vm_name =3D 'MYVMNAME');
=20
but that didn=E2=80=99t help, either. Only rebooting the whole =
hypervisor helped=E2=80=A6 afterwards everything worked again. But only =
for a few hours, then one of the VMs entered the =E2=80=9Cnot =
responding=E2=80=9D state again=E2=80=A6 again only a reboot helped. =
Yesterday it happened again:

vdsm high mem usage
by Michael Kleinpaste
Hi everybody.
So I ran into that high mem usage thing. The problem I have with patching
is that this is a live system so I can't do it mid day. Can anybody tell
me if it is possible to just restart the vdsm service or does the host have
to be in "maintenance mode" before restarting it? It is using gluster
storage, if that makes a difference as well.
Thanks,
--

VLAN with one NIC
by gregor
Hi,
is it possible to use different VLAN with one NIC in ovirt?
I can not add a logical network configured as VLAN to my ovirtmgmt
interface, I get "Cannot have a non-VLAN VM network and VLAN-tagged
networks on one interface."
The setup for the Port is a trunk of different tagged VLAN's and the
default VLAN1 is untagged. Normally this work under centos where I give
the nic eth0 an IP and create a nic eth0.10 for the VLAN with ID 10 and
set an IP for it.
cheers

Running an ovirt phyton scrit on a newly RHEL7 installed system

Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable
Hi,
I'm trying to retrieve datacenters clusters hosts and vms by using ovirt p=
ython script needing some imports :
import sys
from ovirtsdk.api import API
from ovirtsdk.xml import params
from threading import Thread
import time
import logging
Then I got following error :
=D8 python test2.py
Traceback (most recent call last):
File "test2.py", line 32, in <module>
from ovirtsdk.api import API
ImportError: No module named ovirtsdk.api
As I run it on a "fresh install" rhel7 server ( python has been added), I'm=
wondering what's the minimum packages list I've to install
on this machine to be able to run this script ? ( I run it correctly on th=
e system where the ovirt engine is installed)
Thanks.

Hi,
Ovirt quick start guide mentions this :
Install Hosts
After you have installed the oVirt Engine, install the hosts to run your vi=
rtual machines. In oVirt, you can use either oVirt Node, Fedora or CentOS a=
s hosts.
Is it O.K. to use a RHEL6 or 7 server as host to run Guest VMs ?
I assume that's ovirt engine is not installed on one of these hosts ( it's=
better to use a dedicated machine) ?
Thx

Strange fencing behaviour 3.5.3
by Martin Breault
Hello,
I manage 2 oVirt clusters that are not associated in any way, they each
have their own management engine running ovirt-engine-3.5.3.1-1. The
servers are Dell 6xx series and the power-management is configured using
idrac5 settings and each cluster is a pair of hypervisors.
The engines are both in a datacenter that had an electrical issue, each
cluster is at a different unrelated location. The problem I had was
caused by a downed switch causing the individual engines to continue to
function, however no longer have connectivity to their respective
clusters. Once the switch was replaced (about 30 minutes of downtime) ,
when connectivity was resumed, both engines chose to fence one of the
two "unresponsive hypervisors" by sending an iDrac command to power down.
The downed hypervisor Cluster1 for some reason, 8 minutes later, got a
iDrac command to power-up again. When I logged into the engine, the
guests that were running on the powered-down host were in "off" state.
I simply powered them back on.
The downed hypervisor on Cluster2 stayed off, and was unresponsive
according to the engine, however the VMs that were running on it were in
an unknown state. I had to power on the host and click the "host has
been rebooted" dialog for the cluster to free these guests to be booted
again.
My question is, is it normal for the engine to fence one or more hosts
when it loses connectivity to all thehypervisors in the cluster? Is
there a minimum of 3 hosts in a cluster for it to not fall into this
mode? I'd like to know what I can troubleshoot or how I can avoid an
issue like this should the engine be disconnected from the hypervisors
temporarily and then resume connectivity only to kill the well-running
guests.
Thanks in advance,
Marty

[HA] Restart guest on other node on network SAN problem
by Lionel Caignec
Hi,
i've ovirt nodes connected to a data network (provide disk for guest) with 10Gb networking.
Recently i face a problem : one of my node have lost connectivity to the SAN.
So ovirt put all guest in "Pause" state, but when connectivity came back ovirt did not restart the Guest.
So my question : is it possible on "disk connectivity lost" on one node, to restart guest on other node (HA features). Or at least auto resume guest when "disk connectivity" came back.
Thanks

lc_messages issue in 3.6 beta 5 upgrade
by Jon Archer
Hi all,
just wanted to share an error i'm seeing with the upgrade process from
3.5 to 3.6 b5.
when running engine-setup on the hosted-engine I'm seeing an error
saying that lc_messages should be en_US.utf8.
problem is that isn't my locale, nor would it be the case in quite a lot
of other installations. My lc_messages is set to en_GB.utf8

Problem with network VM
by Rocha Neto
Hello friends, okay with you? I hope you are well.
I've tried to get in some mailing lists and could not. Did you could get me
a question, or send me somewhere that I can study about?
I rode an environment with oVirt. I have the engine running on the IP
xx.xx.xx.45 and Host with the IP xx.xx.xx.46.
Everything works fine, datacenter, cluster, host, storage (iSCSI). But when
I create a VM, install CentOS for example. I can not access the network. I
can not ping any address out. What should I do? Is there some setting I
need to change?
The host has two interfaces eth0 and ovirtmgmt, all working perfectly well.
Could someone give me a light?
Thanks in advance!
Update:
I have /27 (Netmask 255.255.255.224)
xx.xx.xx.45 engine
xx.xx.xx.46 host (vdsm) ovirtmgmt bridge
xx.xx.xx.33 is my gateway
Network of VM is:
xx.xx.xx.52
xx.xx.xx.33 gw
