[ovirt-users] Re: CPU Compatibility Problem after Upgrading Centos 8 Stream Host

[k.gunasekhar--- via Users]

I also end up with the same problem today. How did rollback yum i see many yum 
updates in the yum history.

Here is what the error says. 

The host CPU does not match the Cluster CPU Type and is running in a degraded 
mode. It is missing the following CPU flags: model_IvyBridge, spec_ctrl. Please 
update the host CPU microcode or change the Cluster CPU Type.

Thanks Jeff Bailey,

The issue was with edk2-ovmf, rolling that package back and it started 
recognizing the CPU correctly.

[nsurma]

Hello,

I am also having the same issue after upgrading today but with the skylake CPU. 
Message states the following flag model_Skylake-Server-noTSX-IBRS is missing. 
Also running Centos 8 stream not the ovirt node. Thanks

[ovirt-users] issue creating disk with rest api using json format

[Pascal D]

I am unable to create disk using JSON however the same query in XML works 
great. In Json I get the following message back: 
{
  "detail": "For correct usage, see: 
https://ov1.butterflyit.com/ovirt-engine/apidoc#services/disks/methods/add";,
  "reason": "Request syntactically incorrect."
}

Both use POST /ovirt-engine/api/disks and the content-type is either 
application/json or application/xml

Here is the request in JSON:

{
   "id": "866770c3-acf9-4f67-b72c-05ed241908e4",
"name": "mydisk",
"description": "test disk",
"bootable": false,
"shareable": true,
"provisioned_size": 1024000,
"interface": "virtio",
"format": "cow",
"storage_domains": {
"storage_domain": {
  "name": "VMS"
}
}
}

And here it is in XML


false
mydisk
test Drive
virtio
1024000
cow

Meanwhile there is a workaround that should fix the situation.
You need to run (with root account) the following command:

chmod u+s /usr/libexec/cockpit-session

Please let us know if that works for you.

[ovirt-users] Re: Ovirt 4.4.6.8 High Performance VM quirkiness

[Don Dupuis]

I didn't change vm type. I would set the vm, let it run, do a shutdown, and
then when I went to edit to look at configuration is when it changed. I
will test using desktop VM type and if I do the same things and it stays
with what I expected, I will use desktop vm type and not mess with HP vm
type. One thing I did forget to mention is that the vm was created from a
template that was of HP vm type.

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.

If all the hosts are non-responding, the data center status is also non-
operational. Start with investigation why these hosts are down/non-responsive. 
If there are alive and you can ssh there, check is vdsmd service is running. 
If it's running, check vdsm logs (/var/log/vdsm/vdsm.log) if there are any 
error.

Also 3.4 is very old version, once you make it running, you should really 
consider to upgrade

was using the same settings in 4.3 and never exhibited this behavior. What
I have observed so for is that I disabled Headless, disabled cpu pinning,
and changed numa config. When I shutdown the vm, they revert to default of
Headless enabled, cpu pinning is set and the numa config changed. This is
not what I expect to happen. Has anyone else noticed this behavior?

Hi,
I tried to reproduce it (without update):
1. Create a VM with HP type.
2. Set it with console.
3. Edit the VM again, click OK.
4. Edit the VM to see the configuration.

Everything sticks to the first configuration.
Note that if you change the VM type to server/desktop and move it again to
High Performance, some configurations will change.
In 4.4.5 we added the auto pinning feature, to high performance VMs we
automatically set it to existing - which overrides the cpu pinning and numa
configuration of the VM.
This behavior executed each time you edited the VM in the UI, it wouldn't
change the headless, only the CPU pinning and NUMA.
However, in 4.4.6.6, we fixed a bug[1] to prevent this behavior to some
extent. If you change the type, it will change the policy, but if the VM is
already configured as High Performance and you didn't change it, it will
leave it as is.

The question would be if you change the VM type? If so, it is expected.
Liran.

[ovirt-users] Data Centers status Not Operational

[nexpron]

Hi everyone,
I found 3 servers (HV1, HV2, HV3) that contains VMs at another servers room. 
These servers are hosts based on KVM.
I logged into oVirt Engine Web Administration. Data Centers tab show me only 
one entry
Name: RCV
Storage: Shared
Status: Not Operational
Compability Version: 3.4 
Description: [Empty]
Webbrowser oVirt Engine Web Administrator show me
oVirt Engine Version: 3.4.0-1.el6
One VM on HV3 has stopped, Hosts tab show Non Responsive Status for every host 
(HV1-3); every VM in Virtual Machines tab  show Unknown status. 
What do I'll do to change status in Data Center? How to start debug the reason? 
Last administrator leave documentation in vestigial form :)

DataCenter: RCV
-->Cluster: RCV_Cluster
>Host: HV1 node
>Host: Hv2 node
>Host: HV3 engine

Best regards,
nexpron

[ovirt-users] Ovirt 4.4.6.8 High Performance VM quirkiness

[Don Dupuis]

I created a high performance vm and everything is fine. I stop the virtual
machine and make edits to it and again runs correctly. I shutdown the vm
and click the edit tab to look at what I changed and it is now back to the
defaults and my edits are gone. Is this now the intended result. I was
using the same settings in 4.3 and never exhibited this behavior. What I
have observed so for is that I disabled Headless, disabled cpu pinning, and
changed numa config. When I shutdown the vm, they revert to default of
Headless enabled, cpu pinning is set and the numa config changed. This is
not what I expect to happen. Has anyone else noticed this behavior?

Thanks
Don

[ovirt-users] Re: Error while deploying Hyperconverged oVirt 4.3.3(el7) + GlusterFS

[techbreak--- via Users]

I've tried also with command line using "hosted-engine --deploy" and following 
the guided tour, but then I end up with this error:

[ INFO  ] TASK [ovirt.hosted_engine_setup : Validate selected bridge interface 
if management bridge does not exists]
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The 
selected network interface is not valid"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing

How can I solve this problem?

[ovirt-users] CPU Compatibility Problem after Upgrading Centos 8 Stream Host

[Nur Imam Febrianto]

Hi,
This morning I have a problem that suddenly my Host (Using Centos 8 Stream, not 
oVirt Node) showing error with Cpu Compatibility. It says my CPU doesn’t have 
Haswell-noTSX and spec_ctrl flag. After downgrading the kernel back from 4.18.0 
– 305 to 4.18.0 – 301.1 and rollback yum update, it working again. Do anybody 
having same issue ?
I’m using Xeon E5-2695v4 with cluster compatibility Secure Intel Haswell. Using 
oVirt 4.4.6 on CentOS Stream host.

Thanks before.

Ah, that makes sense :)
I hope someone else with DR experience can share their thoughts.

Site A has volume data2 which geo-replicates to Site B

Site B has volume data1 which geo-replicates to Site A

I will look at the engine upgrade and ansible today.
