Hello Developers,
We are new to ovirt. We unfortunately managed to break our oVirt installati=
on. The engine VM does not seem to start after we updated to 4.0 from 3.6 a=
nd did a restart.
We are looking for someone specialized to fix this kind of issues. I have f=
ailed to find anyone who provides support for oVirt so resorting to the use=
rs list now. Already tried using the users list and someone did try to help=
but could not get it to work. You can see the thread below for reference a=
nd logs that I posted:
http://lists.ovirt.org/pipermail/users/2017-May/082309.html
Can anyone help please?

Host name already in use in oVirt Engine
by FERNANDO FREDIANI

--------------3A9AA83C242C9D0BB163DB52
Content-Type: text/plain; charset=utf-8; format=flowed

Hello.
I had a previous Datacenter and Cluster with a Host in it which I have
removed completelly from oVirt Engine. In order to remove I did the
following steps:
- Removed all Virtual Machines on the top of the Host
- Put the only Local Datastore in Maintenence mode (It didn't allow to
remove it for some reason. Said I had to remove the Datacenter instead)
- As the Datastore couldn't be remove so the Host. I then removed the
Datacenter and it removed everything.
Then I created a new Cluster and tried to add the same Host with the
same hostname in it and I am getting the message: "Cannot add Host. The
Host name is already in use, please choose a unique name and try again."
It seems that something was left lost in the Database which still
beleives that host exists in oVirt Engine. How can I clean that up and
add it again as I am not willing to change its name.
Thanks
Fernand

SPM in case of Failure
by Arsène Gschwind
This is a multi-part message in MIME format.
--------------2697A26DEF0A6FEBE4ECD7F9
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 8bit
Hi
Our setup looks like:
- 2 clusters in 2 different site connected with 10GBit LAN
- Storage based on FC SAN replicated on both site and available for both
site (The LUNs are available over 4 pathes, 2 from each site)
My observation:
In case one site goes down and this site owned SPM is it not possible to
move or force SPM on the second site.
On the site which is down it's possible to reset all VMs that crashed
using the "Confirm Host rebooted" menu on the oVirt Host but this does
not reset SPM.
The only solution I found was to bring the Host which owned SPM up again
to be able to move it to the other site and then reactivate the storage
domains.
Is this a normal behavior?
Is there any way to force SPM reelection ?
Thanks for your help or idea...
Regards,
Arsène

Python-SDK4: Managing accents?
by nicolas@devels.es
Hi,
We're running Python SDK (ovirt-engine-sdk-python) ver 4.1.4 and we're
having some issues getting values that contain accents. For example,
this snippet fails:
import ovirtsdk4 as sdk
import ovirtsdk4.types as types
# Create the connection to the server:
connection = sdk.Connection(
url='https://fqdn/ovirt-engine/api',
username='...',
password='...',
ca_file='...',
debug=True,
)
users_service = connection.system_service().users_service()
users = users_service.list()
connection.close()
This snippet fails in the "users = users_service.list()" line, because
one of the records have a tilde (ó).
The trace is:
Traceback (most recent call last):
File "lista_users", line 23, in <module>
users = users_service.list()
File
"/home/ovirt/prueba/ejemplo2/lib/python2.7/site-packages/ovirtsdk4/services.py",
line 22155, in list
return self._internal_get(headers, query, wait)
File

line 310, in _internal_read_body
return reader.Reader.read(response.body)
File
"/home/ovirt/prueba/ejemplo2/lib/python2.7/site-packages/ovirtsdk4/reader.py",
line 297, in read
cursor = xml.XmlReader(io.BytesIO(source.encode('utf-8')))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position
1899: ordinal not in range(128)
Opening the source code (ovirtsdk4/reader.py) file and seeking the exact
line that fails I can see:
if isinstance(source, str):
cursor = xml.XmlReader(io.BytesIO(source.encode('utf-8')))
If I add a line just after the 'if' being "cursor =
cursor.decode('utf-8')", it seems to work, but I guess the source code
should handle this kind of situations.
Is this a known issue? Should I open a BZ? Any workaround meanwhile?
Thanks.

Question about Clusters and Storage usage
by FERNANDO FREDIANI

--------------AF09066F7B7B6BE6AE98327E
Content-Type: text/plain; charset=utf-8; format=flowed

Hello folks.
I have here a scenario where I have one Datacenter and inside it I have
one Cluster which has multiple hosts with Shared storage between them.
Now I am willing to add another standalone host with Local Storage only
and logic tells me to add to the same Datacenter created as they are in
fact in the same physical Datacenter, but as this host has only Local
Storage I shouldn't obviously add to the existing cluster.
Question is: As the Datacenter was created with Storage type Shared
- Should I create a new Cluster and add it to it, even though the
new Host has only Local Storage
- Or should I create another Datacenter with Storage Type Local, a
cluster within it and then add the Host there ?
Thanks
Fernando

hosted-engine network

Hi,
I've migrated our oVirt engine to hosted-engine located on a FC storage
LUN, so far so good.
For some reason I'm not able to start the hosted-engine VM, after
digging in the log files i could figured out the reason. The Network
device was set to "None" as follow:
devices={nicModel:pv,macAddr:00:16:3e:3a:6b:60,linkActive:true,network:*None*,deviceId:56cb4d71-13ff-42a8-bb83-7faef99fd3ea,address:{slot:0x03,bus:0x00,domain:0x0000,type:pci,function:0x0},device:bridge,type:interface}
I've created a new config file
/var/run/ovirt-hosted-engine-ha/vm.conf.new and set the nic device to
ovirtmgnt, the I could start the hosted-engine using :
hosted-engine --vm-start
--vm-conf=var/run/ovirt-hosted-engine-ha/vm.conf.new
The nic device line in vm.conf.new looks like:
devices={nicModel:pv,macAddr:00:16:3e:3a:6b:60,linkActive:true,network:*ovirtmgmt*,deviceId:56cb4d71-13ff-42a8-bb83-7faef99fd3ea,address:{slot:0x03,bus:0x00,domain:0x0000,type:pci,function:0x0},device:bridge,type:interface}
I tried to find out a way to change this setting on vm.conf but it is
constantly rewritten, even when using the webui is say's:
HostedEngine:
* There was an attempt to change Hosted Engine VM values that are locked.
Is there a way to modify/correct the hosted-engine vm.conf file so it
will stay and not be overwritten?
Thanks a lot for any hint/help
rgds,

<p>Hi,</p>
<p>I've migrated our oVirt engine to hosted-engine located on a FC
storage LUN, so far so good.<br>
For some reason I'm not able to start the hosted-engine VM, after
digging in the log files i could figured out the reason. The
Network device was set to "None" as follow:<br>
devices={nicModel:pv,macAddr:00:16:3e:3a:6b:60,linkActive:true,network:<b>None</b>,deviceId:56cb4d71-13ff-42a8-bb83-7faef99fd3ea,address:{slot:0x03,bus:0x00,domain:0x0000,type:pci,function:0x0},device:bridge,type:interface}</p>
<p>I've created a new config file
/var/run/ovirt-hosted-engine-ha/vm.conf.new and set the nic device
to ovirtmgnt, the I could start the hosted-engine using :<br>
hosted-engine --vm-start
--vm-conf=var/run/ovirt-hosted-engine-ha/vm.conf.new</p>
<p>The nic device line in vm.conf.new looks like:<br>
devices={nicModel:pv,macAddr:00:16:3e:3a:6b:60,linkActive:true,network:<b>ovirtmgmt</b>,deviceId:56cb4d71-13ff-42a8-bb83-7faef99fd3ea,address:{slot:0x03,bus:0x00,domain:0x0000,type:pci,function:0x0},device:bridge,type:interface}</p>

trouble when creating VM snapshots including memory
by Matthias Leopold
hi,
i'm having trouble creating VM snapshots that include memory in my oVirt
4.1 test environment. when i do this the VM gets paused and shortly
(20-30s) afterwards i'm seeing messages in engine.log about both iSCSI
storage domains (master storage domain and data storage where VM
resides) experiencing high latency. this quickly worsens from the
engines view: VM is unresponsive, Host is unresponsive, engine wants to
fence the host (impossible because it's the only host in the test
cluster). in the end there is an EngineException
EngineException:
org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException:
VDSGenericException: VDSNetworkException: Message timeout which can be
caused by communication issues (Failed with error VDS_NETWORK_ERROR and
code 5022)
the snapshot fails and is left in an inconsistent state. the situation
has to be resolved manually with unlock_entity.sh and maybe lvm
commands. this happened twice in exactly the same manner. VM snapshots
without memory for this VM are not a problem.
VM guest OS is CentOS7 installed from one of the ovirt-image-repository
images. it has the oVirt guest agent running.
what could be wrong?
this is a test environment where lots of parameters aren't optimal but i
never had problems like this before, nothing concerning network latency.
iSCSI is on a FreeNAS box. CPU, RAM, ethernet (10GBit for storage) on
all hosts involved (engine hosted externally, oVirt Node, storage)
should be OK by far.
it looks like some obvious configuration botch or performance bottleneck
to me. can it be linked to the network roles (management and migration
network are on a 1 GBit link)?
i'm still new to this, not a lot of KVM experience, too. maybe someone
recognizes the culprit...
thx
