Can't delete a disk after a failed upload
by lorenzobarbati02＠gmail.com
Hi,
After trying to upload an ISO via the web interface, the upload remains in the "paused by system" state.
When I click "cancel" in the upload menu the status stops at "finalizing cleanup".
Is there an alternative way to delete this disk?

Found a host rebooting - ways to watch?
by Chris Adams
I just noticed that one of my oVirt physical hosts has been rebooting
due to an apparent hardware voltage fault. It's a Dell, and I've got
their tools installed and am monitoring status, but the issue clears
itself. It has apparently been doing this for a bit now, and we didn't
catch it because (a) there weren't any VMs on it (probably were the
first time but they were restarted elsewhere fast enough that it wasn't
noticed) and (b) it reboots fast enough that at most it pops up in our
monitoring system for one pass and then clears so our NOC either didn't
see it or assumed it was okay since it cleared.
oVirt has been logging alerts when it happens, but seeing that requires
someone to log in and check the logs (and we've got a bunch of different
systems to manage, including multiple oVirt clusters, so nobody is doing
that on a regular basis). We monitor most things with SNMP and/or CLI
checks (we have PRTG, Nagios, and LibreNMS for various different
things).
What are people doing to monitor the health of their oVirt systems? Is
it possible to get alerts emailed to admins? Is there any SNMP support
in oVirt to allow external systems to monitor its health? This setup is
on 4.3.10 if that matters.

Re: EPYC CPU not being detected correctly on cluster
by Lucia Jelinkova
Hi,
oVirt CPU detection depends on libvirt (and that depends on qemu) CPU
models. Could you please run the following command to see what libvirt
reports?
virsh domcapabilities
That should give you the list of CPUs known to libvirt with a usability
flag for each CPU.
If you find out that the CPU is not usable by libvirt, you might want to
dig deeper by querying quemu directly.
Locate any VM running on the system by
sudo virsh list --all
Use the name of a VM in the following command:
sudo virsh qemu-monitor-command [your-vm's-name] --pretty
'{"execute":"query-cpu-definitions"}'
That would give you the list of all CPUs supported by qemu and it will list
all cpu's features that are not available on your system.
Regards,
Lucia

Upgrade hyperconverged self-hosted ovirt from 4.3 to 4.4
by ralf＠os-s.de
Hi,
has anyone attempted an upgrade from 4.3 to 4.4 in a hyperconverged self-hosted setup?
The posted guidelines seem a bit contradictive and not complete.
Has anyone tried it and could share his experiences? I am currently having problems when deploying the hosted engine and restoring. The host becomes unresponsive and has hung tasks.
Kind regards,
Ralf

change domain name from export domain
by jb
Hello,
I needed to rename all domain names from my NFS storage. VM data and
seconds data domains was no problem. But when I try to rename the domain
from export domain, a red popup on top opens with this message:
Uncaught exception occurred. Please try reloading the page. Details:
(TypeError) : ZOj(...) is null
Please have your administrator check the UI logs
I also notice that, when I rename the path an hit enter, it doesn't
write anything to the engine.log
Is this a known issue?
Best regards

Ovirt 4 2 NIC's
by Facundo Badaracco
Hi everyone!
Hope someone can help me with this..
I have 3 servers with centos 8 and ovirt 4 installed. Each server has 2 nic.
Server A = HE (HA)
Nic1= 192.169.2.24 Nic2=no ip
Server B = HE (HA)
Nic1= 192.169.2.25 Nic2=no ip
Server C = simply host.
Nic1= 192.169.2.26 Nic2=no ip
How can i configure the second NIC in each server in order to use it for
clients connect to the vms?. I want one nic for management, the other for
connections.

Can't use ovirt web interface (500 error)
by lorenzobarbati02＠gmail.com
Hi,
After updating to the latest version of ovirt (standalone installed with engine-setup) I am no longer able to use the web ui. After I log in, in fact, I get a modal error entitled "operation canceled" and with content "a request to the server failed, error 500"
Looking at the requests it actually receives an error 500 when it goes to make a request to "/ovirt-engine/webadmin/GenericApiGWTService" which replies "The call failed on the server; see server log for details"
These are the last lines of the engine.log: https://pastebin.com/uFgZASuW
Is anyone experiencing the same problem or know how to fix it?

How do you manage OVN?
by Alex McWhirter
I'm not sure if I' missing something, but it seems there is no way built
in to oVirt to manage OVN outside of network / subnet creation. In
particular routing both between networks and to external networks.
Of course you have the OVN utilities, but it seems that the provider API
is the preffered method of interaction?
As far as i can tell, the only utility that can use this API as intended
is ManageIQ, which is a bit a behemoth if you only need the OVN portion
of things.
So is that it then? Interface with the API directly or use ManageIQ?
Just curious what others are doing in regards to OVN.
