Hi Nicolas, please note that this procedure was intended only for migrating
across different distribution version (el6 -> el7) and not for usual engine
upgrades.
Our existing documentation would need some rework, but the correct
procedure here would be set the hosted engine to global  maintenance
following
https://www.ovirt.org/documentation/self-hosted/chap-Maintenance_and_Upgrading_Resources/#maintaining-the-self-hosted-engine
and then perform an engine upgrade following
https://www.ovirt.org/documentation/upgrade-guide/chap-Updates_between_Minor_Releases/

[ovirt-users] Re-spin of the 4.2.2 GA

[Lev Veyde]

Hi,

We found an issue [1] in the ovirt-engine, and it was decided that even
though we already released the 4.2.2 GA, that the issue is serious enough
for the re-release of the GA to be performed.

We also rebuilt the appliance, to use this new ovirt-engine (version
4.2.2.6).

Users that managed to already install the originally released version, are
encouraged to get the latest one.

Our apologies for the possible inconvenience.

Thanks in advance,

 Hi folks,

 I am facing frequently the following issue:

 On some large VMs (Windows 2016 with two disk drives, 60GB and 500GB)
 when attempting to create a snapshot of the VM, the VM becomes
 unresponsive.

 The errors that I managed to collect were:

Hi Artem,

Thanks.  3 compute hosts, 3 gluster hosts. Checked them all, they're all unique 
(1, 2, 6, 101, 102 and 103), so that isn't the problem.

Found another datapoint that I'm not entirely sure what to do with. Tried 
reinstalling the afflicted host - call it host1. Moved the HE off of it, 
removed it from the GUI, reinstalled. At this point, the SPM was on host3. 
After it was back up, we moved the SPM to host1. The problem ceased on host1 
for several hours and then returned. But most notably, the problem started 
happening on host3!

So it seems somehow related to/influenced by the SPM. And I'm deeply confused.

You can also 'and' and 'or' different parameters, for instance

api/vms?search=name%3DVM1+or+name%3DVM2

which will return VM1 and VM2 if they exist. Note that you will need to URL 
encode your search string to replace all the '=' with %3D and space with +, 
etc. The only = that shouldn't be encoded is the = after search.

For an easy way to find what is available to search on for a particular 
entity, if you go into the webadmin in the search bar you can start typing and 
it will auto complete the different available options. AFAIC those match 
exactly to the search in the REST api.

In order to run the clone operation you must pas the VM name, so you
know the name, so later to fetch the VM you can just run:

api/vms?search=name=thenameofclonnedvm

You can read more about search engine here:


https://www.ovirt.org/documentation/admin-guide/appe-Using_Search_Bookmarks_and_Tags/

So if you have for example following VMs in system:

 vm
 vm1
 vm2
 vm3

And you do search like:

  api/vms?search=name=vm

It will return only single Vm called 'vm', but it always return a 
collection, but with just single item.


And you do search like:

 api/vms?search=name=vm*

It will return all VMs starting on 'vm' string. So it's collection of 
vm, vm1, vm2 and vm3.


So by default it search for exact string, but you may use wildcards to
improve the search.

Re: [ovirt-users] Any monitoring tool provided?

[Peter Hudec]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Hi SHIRLY,

first why zabbix. Zabbix is our primary monitoring tool. Zabbix have
native implementation for VmWare monitoring, which we of course use.
The idea was to use the same monitoring system, alerting for our NOC.

The performance problem is due the how zabbix works, especially zabbix
agent. You could return only one value each query, to to get stat for
VM you have to do  about 10-15 queries. Zabbix agent needs to for the
process ... So overhead is twice, to get the data using api and
forking process.

I see the grafana integration,
https://www.ovirt.org/blog/2018/01/ovirt-report-using-grafana/. This
seems to be dependent on oVirt version, as I see the table names.

So my next steps are:
a)
I took look at the ovirt metrics, looks good. Is it stable on 4.2?
b)
take a look on zabbix sender, but  this have another sets of issues.
For example how to send data olny for some VM/Hosts, not for all if I
do not want to monitor while platform. Data could be collected from
API or DWH
c)
try to do the oVirt poller into zabbix ??

Generally what we need is monitoring and alerting system.
 - alert if Vm is down
 - alert if VM CPU usage is high for period of time
 - alert if there is storage problem /latency, usage, .../
