By online updating you mean hotplug? Or just normal update of fields which
don't need restart (like description)? Because both are possible even with

Re: [ovirt-users] oVirt storage best practise

2017-06-13 Thread Idan Shaby 
Direct luns are disks that are not managed by oVirt. Ovirt communicates
directly with the lun itself, without any other layer in between (like lvm
in image disks).
The advantage of the direct lun is that it should have better performance
since there's no overhead of another layer in the middle.
The disadvantage is that you can't take a snapshot of it (when attached to
a vm, of course), can't make it a part of a template, export it, and in
general - you don't manage it.

Idan

[ovirt-users] New installation

2017-06-13 Thread david caughey 
Hi Folks,

I just got the go ahead to install oVirt to use as a lab.
The servers are:
1xdl360 4x30010k in raid 10 for OS (Manager) should this be clustered with
another server for resiliency
5xdl380 2x30010k for OS 6x1TB7.2k RAID5 on each for a data store
It will all be behind a proxy and be connected with 1GB links, (2x4 bonds)

My plan is to have 1 manager as this is a lab scenario and not production,
(yet), or is it better to have a cluster.

Is it ok to have a data store on each host, (they won't let me have
dedicated storage yet)?
Is it wise to share these data_stores between hosts or should 1 store be
dedicated to each host individually?

There is no need for performance, basically as long as it runs it will work.
The final intention is to have templates for OpenStack and CEPH plus lots
of Linux examples set up with SDN etc.
We have a 90% Windows shop but it is all rapidly changing to OpenStack et
al and I want to try and give people the opportunity to use Linux in the
lab before they are let lose in production.
Plus it gives me the chance to show management exactly what ovirt can do.

Any help, advice or links would be greatly appreciated,

BR/David

[ovirt-users] Ovirt adding routes

Hi,

When installing an ovirt host I got these routes automatically added

default dev ovirtmgmt  table 2886865805  scope link
172.18.19.128/26 via 172.18.19.141 dev ovirtmgmt  table 2886865805

What is their intended purpose? It seems to be stopping packets from being

Re: [ovirt-users] Host name already in use in oVirt Engine

2017-06-13 Thread FERNANDO FREDIANI 

Replying on my own email.

I managed to add the host again but had to do some very manual steps:

- Removed /etc/vdsm/vdsm.id from the Host
- engine=# select vds_id from vds_static where host_name = 'host.name';
- engine=# delete from vds_statistics where vds_id = 'host.name.uuid';
- engine=# delete from vds_dynamic where vds_id = 'host.name.uuid';
- engine=# delete from vds_static where vds_id = 'host.name.uuid';
- uuidgen > /etc/vdsm/vdsm.id on the Host

Should I report it as a bug as when I removed everything from the Admin 
Web Interface it should have done all this clean up in the Database ?

[ovirt-users] problems migrating to hosted engine from bare metal

2017-06-13 Thread cmc 
Hi,

I created a new host to deploy a hosted engine, and then used a backup
from the bare metal engine and restored this, as per the procedure in:

http://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Metal_to_an_EL-Based_Self-Hosted_Environment/

Everything worked fine up until step 15 ('Continue setup') as the
script said the engine was not responding. I tried the reboot option
(option 3), but still it would not connect. So I could not do the
final step involving the internal CA, adding the host to an existing
cluster (of which there were two other hosts). I was able to connect
via vnc and ssh fine to the engine, and from here I could see that the
ovirt-engine service was up. I had to install the aaa-ldap extension
package to enable ldap auth separately however, but once done I was
able to log in, and it showed the old cluster as it was on the bare
metal engine. I added the host that I created the hosted engine on,
and it installed various packages and then I configured the network
and it looked fine, apart from the fact that I could not see a VM
named 'HostedEngine' in the list of VMs. I think however that this was
not a properly working setup, as the NFS storage I used to setup the
hosted engine became unavailable and I think this killed the hosted
engine, which caused it to reboot the host it was on. The hosted
engine has not come back since then, so I'm guessing it either isn't
properly set up for HA or it needs the NFS storage or something else
was not properly done by me in the setup. I've restarted the bare
metal engine for now as I needed it running for now.

 My questions are:

1. My understanding is that the NFS storage is initially used to
create the hosted engine disk image, and is temporary, and that the
hosted engine later gets migrated to the storage used by the rest of
the cluster (which in my case is directly attached to the hosts via
fibre channel). I suspect that this did not happen. The bare metal
engine had some local ISO storage (on a hard disk local to it), which
will not be replicated to the hosted engine VM - will this cause a
problem for the deployment? I can create some new ISO storage later if
not.

2. What is the recommended way to recover from this situation? Should
I just run 'hosted-engine --deploy' again and try and find out what is
going wrong at step 15?

I can probably get the disk image that was on NFS and mount it to find
out what went wrong on the initial deployment, or I can run the
deployment again and then get the log when it fails at step 15.

Ovirt version was 4.1.2.2

Thanks for any help,

Cam

It could be a sanlock issue.
The SPM uses sanlock on the storage domain, so once the SPM host will
be rebooted and sanlock will be released from the storage domain (IINM
after 80 seconds) another Host can obtain a lock on that storage
domain and become the new SPM.
What is the message in the logs that you get when you try to do that?

I would try to attach the storage domain ( detach it first if it is
already attached) so you could register any VMs/Templates/Disks that
were added in the original env.

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 
   users = users_service.list()

   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.

It is a but. I think it was introduced recently. Please try to use
version 4.1.3 and check if it works correctly. Open a bug reporting the
results. We will probably need to do something like this to fix it:

Re: [ovirt-users] Python-SDK4: Managing accents?

2017-06-13 Thread nicolas 
Currently all our scripts are python2-based, not sure if running them 
with Python3 would need a major change, but currently we're happy with 
Python2. I'm still not clear if this is a bug or an additional option 
should be supplied in order to make this work.


Thanks.

What do you mean by "reducing system performance"? on hypervisor side
or manager side?

We're planning to move serveral TBs of vm, splitted in several SD of
1TB of size.


Do you suggest creating a big storage domain of several terabytes?
It would be easier also for our deployment scripts, but we're still
valuating if is a good choice.

> There are also downsides with having big domains, like less flexability

Exactly what i was thinking: how do i replace a component of a storage domain?

Sorry for that, I haven't checked.

I've replaced the log file with a new version which should work i hope.

Many Thanks.

Hi all,

Yanir is right, the local vm.conf is just a cache of what was
retrieved from the engine.

I might be interesting to check what the configuration of the engine
VM shows when edited using the webadmin. Or enable debug logging [1]
for hosted engine and add the OVF dump we send there now and then (the
xml representation of the VM).

[1] See /etc/ovirt-hosted-engine-ha/agent-log.conf and change the
level for root logger to DEBUG

Best regards

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:0x,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:0x,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
