[ovirt-users] Re: integration with openstack nove-compute

[Staniforth, Paul]

Can you use nested virtuliazation with KVM hypervisors?

Also there is OpenStack Platform director  for RHEV, I don't know if there is 
an equivalent for oVirt.

Subject: [ovirt-users] integration with openstack nove-compute

hello dear all,

is it possible to make a compute-nove VM inside oVirt, using which, to be able 
to create VM instances inside oVirt through openstack horizon?
to make it simple, is it possible to have oVirt has the hypervisor for 
openstack, while having a nova-compute node as a VM inside ovirt?
as a hint, the same thing is possible via vsphere vCenter, if we install 
vCenter driver on the nova-compute node.

thank you for your support!

[ovirt-users] silent install failing in 4.3.3.5-1 due to question on fqdn of host

[Brian Kircher]

Anyone happen to know if I can get the following into an answer file for a 
silent deployment? It’s asking to confirm or change from the fqdn of the host 
doing the HE install. Default is fine, but I have to connect in to the screen 
to answer this before it will continue. Default hostname changed to generic in 
below log.  Forward and reverse are both working via dns.

This seems to be a problem of the Ceph iSCSI gateway only, I didn't see

[ovirt-users] Cascade Lake CPU in oVirt

[Matthias Leopold]

Hi,

do I get it right that hypervisor hosts with Cascade Lake CPU could be 
used in oVirt, but would be recognized as "Skylake"? Cascade Lake 
specific features could only be used in VMs after CL is supported by 
libvirt (https://bugzilla.redhat.com/show_bug.cgi?id=1677209) and this 
libvirt is imported in oVirt? We're thinking about buying new hardware 
and I want to be sure it can be used...


thx

may be ovirt devs should confirm that.
do you have a hosted-engine or gluster enabled?

[ovirt-users] Re: Please Help, Ovirt Node Hosted Engine Deployment Problems 4.3.2

[Todd Barton]

Thanks again...I've done all the detail work back in the 3.x days and I thought 
(and was hoping) the node/cockpit setup would make this easier to get 
everything lined up for the HE deploy, but it is not working as expected.  I've 
followed best practices/recommendations, but realize there are not absolute 
specifics in these recommendations...there are a lot of either/or 
statements...which is why I was asking for recommendations.  I've reviewed many 
articles including the "up and running" one like 
https://ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluster-storage.html,
  In everything I've looked at there isn't anything new or different vs what 
I've already done or attempted.



I was very methodical in my initial attempts as I did in my initial install of 
v3.3 years ago which took many attempts and methodical configuration to get it 
up and setup the way I wanted.  What I'm trying to understand is why its not 
coming up in a lab setting with what I would consider to be a pretty remedial 
setup.



I'll get back to a basic setup and run through the process again today or 
tomorrow and post logs of the failure.



Regards,



Todd Barton

Much of such decisions is a matter of personal preferences, 

acquaintance with the relevant technologies and tooling you have 

around them, local needs/policies/mandates, existing infrastructure, 

etc. 



If you search the net, e.g. for "ovirt best practices" or "RHV best 

practices", you can find various articles etc. that can provide some 

good guidelines/ideas. 



I suggest to read around a bit, then spend some good time on planning, 

then carefully and systematically implement your design, verifying 

each step right after doing it. When you run into problems, tell us 

:-). Ideally, IMO, you should not give up on your design due to such 

problems and try workarounds, inferior (in your eyes) solutions, etc., 

unless you manage to find existing open bugs that describe your 

problem and you decide you can't want until they are solved. Instead, 

try to fix problems, perhaps with the list members' help. 



I realize spending a week on what is in your perception a simple, 

straightforward task, does not leave you in the best mood for such a 

methodical next attempt. Perhaps first take a break and do something 

else :-), then start from a clean and fresh hardware/software 

environment and mind. 



Good luck and best regards,

[ovirt-users] Upgrade 4.1.8 to 4.3.3

[christopher . jorgensen]

I am a little behind in updates but I couldn't find any specific instructions 
going from 4.1.8 to 4.3.3. From what I read so far, the process for upgrading 
should be as follows:

4.1.8 --> 4.1.9 
https://www.ovirt.org/documentation/upgrade-guide/chap-Upgrading_from_4.1_to_oVirt_4.2.html
4.1.9 --> 4.2.0 
https://www.ovirt.org/documentation/upgrade-guide/chap-Upgrading_from_4.1_to_oVirt_4.2.html
4.2.0 --> 4.2.8 (use instructions above to upgrade to the latest 4.2 before 
going to 4.3)
4.2.8 --> 4.3.3

Is this correct or should I add / remove upgrade versions?
