virt-viewer - working alternative
by lars.stolpe＠bvg.de
Hi all,
i tryed to use virt-viewer 11 (Windows) with oVirt 4.4 . I also tryed virt-viewer 10, 9, 8, and 7.
The older versions can't handle ISO residing in data domains, the latest version is crashing if try the media button.
Almost all links on the website are dead, no user guide, no prerequisites list...
Since virt-viewer is not working properly and seems to be abandoned, i'm looking for a working alternative.
Is there a working way to get a console of the virtual machines running in oVirt 4.4?

4.4.9 -> 4.4.10 Cannot start or migrate any VM (hotpluggable cpus requested exceeds the maximum cpus supported by KVM)
by Jillian Morgan
After upgrading the engine from 4.4.9 to 4.4.10, and then upgrading one
host, any attempt to migrate a VM to that host or start a VM on that host
results in the following error:
Number of hotpluggable cpus requested (16) exceeds the maximum cpus
supported by KVM (8)
While the version of qemu is the same across hosts, (
qemu-kvm-6.0.0-33.el8s.x86_64), I traced the difference to the upgraded
kernel on the new host. I have always run elrepo's kernel-ml on these hosts
to support bcache which RHEL's kernel doesn't support. The working hosts
still run kernel-ml-5.15.12. The upgraded host ran kernel-ml-5.17.0.
In case anyone else runs kernel-ml, have you run into this issue?
Does anyone know why KVM's KVM_CAP_MAX_VCPUS value is lowered on the new
kernel?
Does anyone know how to query the KVM capabilities from userspace without
writing a program leveraging kvm_ioctl()'s?
Related to this, it seems that ovirt and/or libvirtd always runs qmu-kvm
with an -smp argument of "maxcpus=16". This causes qemu's built-in check to
fail on the new kernel which is supporting max_vpus of 8.
Why does ovirt always request maxcpus=16?
And yes, before you say it, I know you're going to say that running
kernel-ml isn't supported.

ovirt 4.6 compatibility with el8
by Nathanaël Blanchet
Hello community!
I noticed that rhel9 doesn't not support anymore ISP2532-based 8Gb
Fibre Channel HBA.
Given that all of my ovirt hosts are ISP2532-based, I d'like to know if
ovirt 4.6 will be still compatible with el8 or will only support el9.

oVirt hosted-engine deployment times out while "Wait for the host to be up"
by brwsergmslst＠gmail.com
Hi all,
I am currently trying to deploy the hosted-engine without success.
Unfortunately I cannot see what I am missing here. It'd be nice if you could put an eye on it and help me out. Below is an excerpt of the logfile generated.

IBM ESS remote filesystem as POSIX compliant fs?
by arc＠b4restore.com
Hi all,
We are trying to mount a remote filesystem in oVirt from an IBM ESS3500. but it seems to be a little against us.
everyting i try to mount it i get this in supervdsm.log(two different tries):

i have tried earlier in the same oVirt version two map a SAN LUN directly to the hypervisor and create a local gpfs filesystem and that was able to mount with the below parameters within the gui:
Storage Type : POSIX Compliant FS
HOST : The host that has scale installed and mounted
Path : /essovirt01
VFS Type: gpfs
Mount Options: rw,relatime,dev=essovirt01
This works. but with a remote filesystem it does not. im not sure why as it should pretty close to a local filesystem as it is granted with : File system access: essovirt01 (rw, root allowed) and mounted with /essovirt01 on /essovirt01 type gpfs (rw,relatime,seclabel)
Anybody have a clue what to do ? seems weird there should be such a difference from a locally owned to a remote owned fs when mounted through gpfs remotefs/remotecluster option.
and just to verify, i have given the filesystem the correct permission for ovirt : drwxr-xr-x. 2 vdsm kvm 262144 Mar 31 10:33 essovirt01
Thanks in advance.

OVirt Self Hosted Enging VM issue
by linim＠gdls.com
Hello
If this is a repeat discussion, I do apologize but I am looking to see if anyone else out there as had or heard of this issue happening?
I am attempting to install a KVM hosts with a Self-Hosted-Engine. When it goes to install the OVIRT engine on the VM being created under its temporary IP, I am noticing that the VM will disconnect, and I lose all network connectivity on it.
This is in attempt to install OLVM using the self-hosted-engine referencing oracle Doc ID 2933018.1. I have engaged oracle support, but I am just hoping that perhaps someone else has run into this issue and they can offer up avenues of investigation?
If his is outside the scope of an oVirt discussion as it is OLVM, then this can be closed out.

Encrypted VNC request using SASL not maintained after VM migration
by Jon Sattelberger
I recently followed the instructions for enabling VNC encryption for FIPS enabled hosts [1]. The VNC console seem to be fine on the host where the VM is initially started (excluding noVNC in the browser). The qemu-kvm arguments are not maintained properly upon VM migration, declaring "password=on" in the -vnc argument. Subsequent VNC console requests will result in an authentication failure. SPICE seems to be fine. All hosts and the engine are FIPS enabled running oVirt-4.5.4-1.el8.
Is there a way to maintain the absence of "password=on"after VM migation? Perhaps a hook in the interim.
Initial VM start:
-object {"qom-type":"tls-creds-x509","id":"vnc-tls-creds0","dir":"/etc/pki/vdsm/libvirt-vnc","endpoint":"server","verify-peer":false} -vnc 192.168.100.67:0,tls-creds=vnc-tls-creds0,sasl=on,audiodev=audio1 -k en-us

Failing "change Master storage domain" from gluster to iscsi
by Diego Ercolani
In the current release of ovirt (4.5.4) I'm currently experiencing a fail in change master storage domain from a gluster volume to everywhere.
The GUI talk about a "general" error.
watching the engine log:

clock skew in hosted engine and VMs due to slow IO storage
by Diego Ercolani
I don't know why (but I suppose is related to storage speed) the virtual machines tend to present a skew in the clock from some days to a century forward (2177)
I see in the journal of the engine:
Mar 28 13:19:40 ovirt-engine.ovirt NetworkManager[1158]: <info> [1680009580.2045] dhcp4 (eth0): state changed new lease, address=192.168.123.20

Mar 28 13:29:40 ovirt-engine.ovirt NetworkManager[1158]: <info> [1680010180.2039] dhcp4 (eth0): state changed new lease, address=192.168.123.20

Apr 01 08:15:42 ovirt-engine.ovirt chronyd[1072]: Can't synchronise: no selectable sources
When this happens in the hosted-engine tipically:
1. the DWH became unconsistent as I stated here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/KPW5FFKG3AI6... or https://lists.ovirt.org/archives/list/users@ovirt.org/thread/WUNZUSZ2ARRL...
2. the skew causes the engine to kick off the nodes that appears "down" in "connecting" state
This compromises all the task in pending state and raise countermeasures to the ovirt-engine manager and also vdsm daemon.
I currently tried to put in engine's crontab every 5 minutes a "hwclock --hctosys" as it seem the hwclock don't skew
