Re: [ovirt-users] Ovirt node host installation failing in engine
by Shalabh Goel
Hi
I just want to know if there is any way I can disable the yum looking for
updates on the internet on the node?
Please help me out here.
Thanks

planned jenkins and resources downtime
by Evgheni Dereveanchin
Hi everyone,
As part of a planned maintenance window I am going to
apply OS updates and reboot the Jenkins master along
with our resources file server.
Affected services:
jenkins.ovirt.org
resources.ovirt.org
This means that no new jobs will be started on the Jenkins
and our repositories will be unavailable for a short
period of time.
I will follow up on this email once all services
are back up and running.
Regards,
Evgheni Dereveanchin

How to migrate Self Hosted Engine
by Gianluca Cecchi
Hello,
I have an Hyperconverged gluster cluster with SEH and 3 hosts born in 4.0.5.
The installation was done starting from ovirt01 (named hosted_engine_1 in
webadmin gui) and then deploying two more hosts: ovirt02 and ovirt03 from
web admin gui itself.
All seems ok.
I can migrate a normal VM from one host to another one and nice that I
don't loose console now.
But if I try from webadmin gui to migrate the self hosted engine I get this
message:
https://drive.google.com/file/d/0BwoPbcrMv8mvY3pURVRkX0p4OW8/view?usp=sha...
Is this because the only way to migrate engine is to put its hosting host
to maintenance or is there anything wrong?
I don't understand the message:
The host ovirt02.localdomain.local did not satisfy internal filter HA
because it is not a Hosted Engine host..
some commands executed on hosted_engine_1 (ovirt01):
[root@ovirt01 ~]# vdsClient -s 0 glusterHostsList
{'hosts': [{'hostname': '10.10.100.102/24',

Released update for 4.0.5?
by Gianluca Cecchi
Hello,
in webadmin GUI I see on my 4.0.5 hosts a message related to updates
available
If I run yum update in my plain CentOS 7.2 hosts I get:
1) vdsm packages
vdsm x86_64 4.18.15.3-1.el7.centos ovirt-4.0
688 k

How can I manage gluster updates on gluster environment with 3 hosts?
Separated by vdsm updates or in the same run?
Any hint/caveat?
Thanks

deleted then rebuilt node still showing up in status
by Charles Kozler
I put the node in to maint. mode, removed all VMs from it, and then deleted
it from the web UI. I then rebuilt it with hosted-engine --deploy and
indicated it is now node 4 (was previously #3) and now in --vm-status it is
still showing up as stale data
What can I do?
In fact, it looks like ovirt thinks its still in maint mode I am presuming
because I used the same host name?

In web UI it does not show the node (node02 / Host ID #4) as being in

can't import vm from KVM host
by Nelson Lameiras
Hello,
I'm trying to import virtual machines from a KVM host (centos 7.2) to an oVirt 4.0.2 Cluster using the "import" feature on GUI.
If the original VM is using RAW/QCOW2 files as storage, everything works fine.
But if the original VM is using a special block special device as storage (like a LVM or SAN volume), it's simply not recognized.
The VM does appear in the import list of the KVM host, but it's disk count is 0!
Is this a known technical obstacle or am I doing something wrong ?
below is the storage part of the xml describing the original VM :
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source dev='/dev/mapper/vg_01-lv_sys'/>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</disk>
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source dev='/dev/sdc'/>
<target dev='vdb' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
</disk>
We have hundreds of virtual machines in production with this type of configuration... How can we migrate them safely to oVirt?
thanks

How to update ovirt on a single-host hosted-engine host
by Derek Atkins
Hi,
I've got ovirt running on a single host (with hosted-engine). I just
upgraded the engine from 4.0.4 to 4.0.5. That was pretty easy; I just
put the system into global maintenance mode, then yum update, then
engine-setup, then took the host out of maint mode. Easy peasy.
Now, I want to update the host itself. Since it's a single host system
I know I'll need to shut down all the VMs (because there's no place to
migrate them). This means I'll need to shut down the engine VM, too.
That would imply that I can't use the "Update" feature from the ui,
right?
So what IS the process to properly update a single-host host? My guess
is:
* shutdown all the VMs
* go into global maint mode (what IS the difference between global and
local?)
* shutdown the engine/engine VM
* yum update on the host
* restart services (or reboot, I guess)
* bring the system out of maintenance mode
Am I missing a step? Do I need to run hosted-engine --deploy again
similar to how I needed to run "engine-setup" on the engine? Or is
there something else I need to run?
Thanks,
-derek
