Any one uses Nvidia T4 as vGPU in production?
by Arman Khalatyan
Hello,
any successful stories of the Nvidia T4 usage with the Ovirt?
I was wondered if one would get 2 hosts each with T4s , are there live
migrations possible?
thanks,
Arman

Bad Gateway buhaa
by Vrgotic, Marko
Dear oVIrt,
Although it should be simple, I am failing to understand the connection between Default Gateway setting and Bad Gateway issue.
On which network I need to set default gateway:
Our ovirtmgmt is set not to be used by Guest VMs, only Hosted-Engine.
We have tenant1 network which is assigned to VM Guest instances and it has Default Gateway, working one 😊.
Why am I still seeing this message:
2019-07-04 12:53:08,991Z ERROR [org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-54) [2cfff521] Command 'org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand' failed: EngineException: (Failed with error Bad Gateway and code 5050)
What am I doing wrong?
If you need more info or log data, just let me know.
oVIrt 4.3.3
Kindly awating your reply.

Re: Anaconda crashing on start while trying to Install oVirt Node on bare metal
by Strahil
If you don't have a raid controller with battery-backed cache - disable the raid in bios.
Fake raids are just like software raid, use the cpu for calculations and could be a potential problem if the Motherboard dies.
Software raid (controlled by mdadm) and lvm raid (sane driver but controlled from lvm) can easily be recovered on any type of linux (as long as it is not too old ofc) and do not have the minuses of the fake raid.
Best Regards,

Re: lvm agregation of lun in a storage domain
by Strahil
I think the simplest way is to get a new LUN and migrate the VM disks to it.
Once the 2 old LUNs are free - you can release them both.
