Changing disk QoS causes segfault with IO-Threads enabled (oVirt 4.3.0.4-1.el7)
by jloh＠squiz.net
We recently upgraded to 4.3.0 and have found that when changing disk QoS settings on VMs whilst IO-Threads is enabled causes them to segfault and the VM to reboot. We've been able to replicate this across several VMs. VMs with IO-Threads disabled/turned off do not segfault when changing the QoS.
Mar 1 11:49:06 srvXX kernel: IO iothread1[30468]: segfault at fffffffffffffff8 ip 0000557649f2bd24 sp 00007f80de832f60 error 5 in qemu-kvm[5576498dd000+a03000]

Happy to supply some more logs to someone if they'll help but just wondering whether anyone else has experienced this or knows of a current fix other than turning io-threads off.

Oracle Virtualization Manager 4.5 anyone?
by Thomas Hoberg
Redhat's decision to shut down RHV caught Oracle pretty unprepared, I'd guess, who had just shut down their own vSphere clone in favor of a RHV clone a couple of years ago.
Oracle is even less vocal about their "Oracle Virtualization" strategy, they don't even seem to have a proper naming convention or branding.
But they have been pushing out OV releases without a publicly announced EOL almost a year behind Redhat for the last years.
And after a 4.4 release in September 22, a few days ago on December 12th actually a release 4.5 was made public.
I've operated oVirt 4.3 with significant quality issues for some years and failed to make oVirt 4.4 work with any degree of acceptable stability but Oracle's variant of 4.4 proved to be rather better than 4.3 on CentOS7 with no noticable bugs, especially in the Hyperconverged setup that I am using with GlusterFS.
I assumed that this was because Oracle based their 4.4 in fact on RHV 4.4 and not oVirt, but since they're not telling, who knows?
One issue with 4.4 was that Oracle is pushing their UE-Kernel and that created immediate issues e.g. with VDO missing modules for UEK and other stuff, but that was solved easily enough by using the RHEL kernel.
With 4.5 Oracle obviously can't use RHV 4.5 as a base, because there is no such thing with RHV declared EOL and according to Oracle their 4.5 is based on oVirt 4.5.4, which made the quality of that release somewhat questionable, but perhaps they have spent the year that has passed since productively killing bugs... only to be caught by surprise again, I presume, by an oVirt release 4.5.5 on December 1st, that no one saw coming!
Long story slightly shorter, I've been testing Oracle's 4.5 variant a bit and it's not without issues.
But much worse, Oracle's variant of oVirt seems to be entirely without any community that I could find.
Now oVirt has been a somewhat secret society for years, but compared to what's going on with Oracle this forum is teaming with life!
So did I just not look around enough? Is there a secret lair where all those OV users are hiding?
Anyhow, here is what I've tested so far and where I'd love to have some feedback:
1. Setting up a three node HCI cluster from scratch using OL8.9 and OV 4.5
Since I don't have extra physical hardware for a 3 node HCI I'm using VMware workstation 17.5 on a Workstation running Windows 2022, a test platform that has been working for all kinds of virtualization tests from VMware ESXi, via Xcp-ng and ovirt.
Created three VMs with OL8.9 minimal and then installed OV 4.5. I used the UEK default kernels and then had an issue when Ansible is trying to create the (local) management engine: the VM simply could not reach the Oracle repo servers to install the packages inside the ME. Since that VM is entirely under the control of Ansible and no console access of any type is possible in that installation phase, I couldn't do diagnostics.
But with 4.4 I used to have similar issues and there switching back to the Redhat kernel for the ME (and the hosts) resolved them.
But with 4.5 it seems that UEK has become a baked-in dependency: the OV team doesn't even seem to do any testing with the Redhat kernel any more. Or not with the HCI setup, which has become deprecated somewhere in oVirt 4.4... Or not with the Cockpit wizard, which might be in a totally untested state, or....
Doing the same install on OL 8.9 with OV 4.4, however, did work just fine and I was even able to update to 4.5 afterwards, which was a nice surprise...
...that I could not repeat on my physical test farm using three Atoms. There switching to the UEK kernel on the hosts caused issues, hosts were becoming unresponsive, file systems inaccessible, even if they were perfectly fine at the Gluster CLI level and in the end the ME VM simply would not longer start. Switching back to the Redhat kernel resolved things there.
In short, switching between the Redhat kernel and UEK, which should be 100% transparent to all things userland including hypervisors, doesn't work.
But my attempts to go with a clean install of 4.5 on a Redhat kernel or UEK is also facing issues. So far the only thing that has worked was a single node HCI install using UEK and OV 4.5 and upgrading to OV 4.5 on a virtualized triple node OV 4.4 HCI cluster.
Anyone else out there trying these things?
I was mostly determined to move to Proxmox VE, but Oracle's OV 4.5 seemed to be handing a bit of a life-line to oVirt and the base architecture is just much more powerful (or less manual) than Proxmox, which doesn't have a management engine.

4.5.4 with Ceph only storage
by Maurice Burrows
Hey ... A long story short ... I have an existing Red Hat Virt / Gluster hyperconverged solution that I am moving away from.
I have an existing Ceph cluster that I primarily use for OpenStack and a small requirement for S3 via RGW.
I'm planning to build a new oVirt 4.5.4 cluster on RHEL9 using Ceph for all storage requirements. I've read many online articles on oVirt and Ceph, and they all seem to use the Ceph iSCSI gateway, which is now in maintenance, so I'm not real keen to commit to iSCSI.
So my question is, IS there any reason I cannot use CephFS for both hosted-engine and as a data storage domain?
I'm currently running Ceph Pacific FWIW.

ovirt-45-upstream GPG Key Error
by Matthew J Black
Hi All,
We just picked up a GPG Key error when running `dnf install ovirt-engine-appliance` in preparation of a fresh oVirt v4.5.5 install on RL v9.3:

An error? An issue with the repo definition? Can it safely be ignored (normally I'd say "No" but its from the oVirt Tam's own repo...)? Is the fingerprint above the correct one (and for that matter, where is the GPG Key's Fingerprint recorded on the oVirt Website so that we can check compliance ourselves)?
Anyway, thought I'd let people know (further details can be provide upon request)

Hi, for those who remember the Linux Counter project, if you'd like other
to know you're using oVirt and know some details about your deployment,
here's a way to count you in:

Internal pentest result : Ovirt-engine authentication bypass
by Jirka Simon
Hello ovirt comunity.
We had an internal pentest here and one finding is
*Ovirt-engine authentication bypass.*
Ovirt-engine, as deployed on ovirtm.XXX.XXX.cz, contains an
authentication bypass. It is
possible to directly call the CreateUserSessionCommand using runAction
exposed by /ovirt-
engine/webadmin/GenericApiGWTService.
*This action explicitly enables everyone to call it:*
```/
@Override
protected boolean isUserAuthorizedToRunAction() {
return true;
}
/```
The behavior of this call differs based on the
ENGINE_SSO_ENABLE_EXTERNAL_SSO configuration
option:
```
/boolean externalSsoEnabled =
EngineLocalConfig.getInstance().getBoolean("ENGINE_SSO_ENABLE_EXTERNAL_SSO");
DbUser dbUser = externalSsoEnabled ?
dbUserDao.getByUsernameAndDomain(params.getPrincipalName(), authzName) :
dbUserDao.getByExternalId(authzName, params.getPrincipalId());/
```
If this option is enabled, usernames are used to locate users. If it's
disabled, the externalId
(which seems to be a randomly generated GUID) is used to locate users.
If the specified user exists, a session is returned for the user. If the
specified user doesn't exist,
the user is created in the system. However, the user doesn't get
assigned any group membership
or rights, therefore the session creation fails because of the missing
Login right.
The attempt to modify the users table can be seen in the SQL error
message when attempting to
use a null value for the username (as the endpoint uses GWT, the payload
is mostly unreadable):
```
/POST /ovirt-engine/webadmin/GenericApiGWTService HTTP/1.1
Host: ovirtm.xxx.xxx.cz

Fortunately, in our deplyoment the ENGINE_SSO_ENABLE_EXTERNAL_SSO

set to false, so to create a session for the admin it would be necessary
to know the admin's user
externalId. However, as this is not the default configuration, it is
possible that a later
reinstallation could change the value. Still, it was possible to create
users in the system without
any authentication.
What is the best way to report this security issue?

can hosted engine deploy use local repository mirrors instead of internet ones?

Hi,
hosted-engine --deploy is failing as it is trying to connect to mirrorlist.centos.org:

[ INFO ] TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package]

Opening up access to the internet is a bureaucratic procedure for us, as would be for adding all the URLs to the proxy. We have a lot of repos mirrored locally - is it possible to get hosted-engine to use the local ones? Is there a list? I had a search for files that might contain these repos in various places, but to no avail.
Thanks for any help!

Nested Virtualization in AMD Ryzen
by LS CHENG
Hi all
I am running OLVM 4.5, this is a test setup which was running in my old
workstation with Intel CPU and is nested virtualization (with VMWare
Workstation), the host was running Windows 7 x64, I moved to AMD Ryzen
7950X3D a couple of days ago which runs Windows 11 x64 with 128GB memory
then moved OLVM VM's from the old workstation to this new workstation.
The problem I face now is the KVM hosts shows this error
*Host kvm1 moved to Non-Operational state as host CPU type is not supported
in this cluster compatibility version or is not supported at all*
I modified /etc/modprobe.d/kvm.conf and changed
options kvm_amd nested=0
to
options kvm_amd nested=1
reboot the kvm host but still getting same error, I verified the
modification and seems good
[root@kvm1 ~]# cat /sys/module/kvm_amd/parameters/nested
1
In Windows 11 I have hyper-v off and Memory Integrity is also off.
Am I missing any additional steps?
Thanks
