oVirt 4.4 requires engine and hosts based on RH EL / CentOS 8, while your
current env in 4.3 has them based on RH EL 7 / CentOS 7. You have to
reinstall the node that you isolated with the engine.
So after taing the engine at its latest 4.3.x level and rebooting the 4.3
engine OS, you have to follow the steps described in 6.5: stop the
ovirt-engine service, take a backup and copy the generated file outside of
the env, scratch the engine and related node and reinstall it with 4.4
ovirt node and then on the host, now in 4.4, run the command

hosted-engine --deploy --restore-from-file=backup.bck

and so on...

[ovirt-users] Re: oVirt 4.3 DWH with Grafana

2021-10-03 Thread Aviv Litman 
Hi Tommy,
There was a bug in the way we calculate hosts CPU: we didn't consider
the count_threads_as_cores option in the calculation.
The count_threads_as_cores column is available only from ovirt-engine
4.4.6.7 version, and ovirt-dwh 4.4.7. Patches: ovirt-engine
 ovirt-dwh
 So you have to update
the version to 4.4.7.
I will also add a note in the Blog.

You can try to implement the patches I shared manually by changing the
relevant files in engine and dwh and run engine-setup.
*Important note: do not change the minimal version part in dwh
ovirt-engine-dwh.spec.in file.

Feel free to contact me if you have more questions.

Best,
Aviv

[ovirt-users]回复：Re: 回复：Re: 回复： Re: About the vm memory limit

2021-10-03 Thread ‪‪‪tommy‬ 
My virtual machine environment is advised by Oracle to use traditional huge pages and turn off transparent huge pages. At the same time, I have three choices on the KVM server: first, use the transparent huge page as the system default; second, use the traditional huge page as the VIRTUAL machine; third, disable the transparent huge page without activating the traditional huge page. I'd like to know if there is a recommendation order for these three plans？Because I feel that the amount of memory managed and used by the phisical machine is much larger than that of the virtrual machine, if large pages are not enabled on physical machines, will it be effective to enable large pages on virtual machines?Even it's possible to set traditional huge pages on virtual machines on this condation, but I'm not sure it will work as expected.发自我的华为手机 原始邮件 发件人： Strahil Nikolov 日期： 2021年10月3日周日 17:05收件人： sz_cui...@163.com, Strahil Nikolov via Users 抄送： Simon Coter 主题： Re: [ovirt-users]Re: 回复：Re: 回复： Re: About the vm memory limitFor 4.3 - yes.

Yeah, and just to elaborate on that a bit - it doesn't matter which
provider is set there. Even though it is set to KVM in that example, we
don't look at it
For OVA, the important part is to have the URL in the form of "ova://" and oVirt will figure out if it's an OVA that was generated by
oVirt or by a different platform regardless of the provider you set

vdsm supports dynamic allocation of Huge Pages, but 
https://access.redhat.com/solutions/4904441 indicates the issues in 4.3 related 
to hugepages (you can see the solution via RH dev subscription).

If you needed to set them manually and everything works normally, I would have 
picked something like 90-95% in HugePages.

 

Yet, due to the issues described in that solution - it's better to enable 
HugePages only in the Guest.

[ovirt-users] Hosted Engine ansible runner artifacts cleanup

2021-10-03 Thread Erez Zarum 
Hey,
I can't get the artifacts to cleanup, i have configured the ansible runner 
config.yml but it seems not to be running.
Should i restart the ovirt-engine service?

What is the best way to manually cleanup the artifacts (i can't get the correct 
ansible-runner command to clean it up) as it is starting to fill up disk space

Thanks

For 4.3 - yes. This is due to the issues in 4.3Once you move to 4.4 , you 
should be able to enable HugePages (not THP) on the Hypervisors without 
troubles.
I assume that your workload is 'in production' and stability (no downtime) is 
more important that some performance gain from HugePages on the Hypervisors.
@Simon,
any hints when OLVM 4.4 will be released ?
