This applies mostly to host networking, there are cases when host
networking dual stack works fine, the issue is that it has many quirks.
oVirt cannot ensure that those quirks won't happen which might break your
connection.
In VM networks oVirt cares only for L2, with OVN it can also care for L3.
So configuration on your VM networks is up to you.
I can imagine that you could safely mix IPv4 and IPv6 for VM networks
without breaking any hosts, but I did not try that personally.

You can fill RFE but I am afraid that it won't get far due to lack of
manpower.

[ovirt-users] Inquiries regarding missing data in the calendar table created/inserted into the ovirt_engine_history DB.

2021-06-27 Thread whoisjmh 
I recently discovered that the spark-line chart is not displayed in the 
dashboard of the ovirt admin page. As a result of looking up the code and 
query, the data of the calendar table in the ovirt_engine_history DB of 
ovirt-dwh was only available until 2021-01-01 00:00:00, so a query statement ( 
https://github.com/oVirt/ovirt-engine/blob/master/frontend/webadmin/modules/frontend/src/main/resources/org/ovirt/engine/ui/frontend/server/dashboard/dao/HostDwhDAO.
 RIGHT OUTER JOIN of properties) was not getting the correct data. First, the 
existing "generate_series('2011-01-01 00:00'::timestamp, '2021-01-01 00:00', '1 
hours')" part was temporarily modified and applied until 2051. , it was 
confirmed that the spark-line chart was displayed normally.

For this, is there a way I can directly edit the file 
(https://github.com/oVirt/ovirt-dwh/blob/master/packaging/dbscripts/upgrade/03_05_0060_updated_insert_calendar_table_values_script.sql)
 to commit or request a correction? I would like to know.

Confirmed, excluding edk2-ovmf will solve the issue.
Thanks for your info 😊

If it's the same problem that I ran into then it's the latest version of 
edk2-ovmf.  I'm not sure why it was pushed into the repos without a fixed 
libvirt to go with it.

I’m using Xeon E5-2695v4 with cluster compatibility Secure Intel Haswell. Using

[ovirt-users] Question about Template and Storage Domain

2021-06-27 Thread Nur Imam Febrianto 
Hi,

Want to ask about template. For example I have a several template (with disk) 
stored in some Storage Domain. If I create a VM from the template, and when I 
change the parameter of cloned disk into another storage domain (different with 
where the template are stored). The VM always failed to be created. This only 
occurs in VM creation phase, if I create the VM at same storage domain where 
the templates are stored, it created successfully. Is this are “normal” 
behavior ?

Thanks before.

Nur Imam Febrianto

I have dual stack VMs in my deployment and it works fine.
I suspect this is talking about the engine and host infrastructure.

Hello,

I see this tidbit:

Dual-stack addressing, IPv4 and IPv6, is not supported
Switching clusters from IPv4 to IPv6 is not supported.
If I'm understanding this correctly... does that mean I cannot run some VMs 
with IPv4, and other VMs with IPv6, in the same cluster?

If so, that's incredibly disappointing and frustrating.

Is Dual-stack addressing a possible feature request?
IPv4 addresses are expensive... and I have a couple of customers who only 
needs IPv6, so would really prefer to avoid having to pay for IPv4 
addresses for them.
