VM login info
by fawzi＠kdsplumbing.com
Hi guys,
After a lot of attempts, i was finally able to open a VM (centos8-cld) using virt-viewer on my mac (catalina). but i am faced with a login screen. So, where do i get this information from?
or should i be using a different method to log into a vm?
This goes for all of the VMs available by default.
can someone please help me with this?
thanks

4.4 regression: engine-setup fails if admin password in answerfile contains a "%"
by Stephen Panicho
I encountered this error when deploying the Hosted Engine via Cockpit:
[ INFO ] TASK [ovirt.engine-setup : Run engine-setup with answerfile]

The important bit is this: Failed to execute stage 'Initializing': '%' must
be followed by '%' or '(', found: '%JUUj'"
Hey! Those are the last few characters of the admin password. Note that I
don't mean the root password to the VM, but the one for the "admin" user of
the web interface. I added some debug lines to the Ansible play to see the
answerfile that was being generated.
OVESETUP_CONFIG/adminPassword=str:&6&yGfcWf#b%JUUj
Apparently engine-setup can no longer handle an answerfile with a "%"
character in it. This same password worked in 4.3.
Once I changed the admin password, installation progressed normally.

Import VM from export domain using oVirt-4.4
by Joop
Hi All,
I'm testing a shiny new oVirt-4.4.02, selfhosted engine HCI gluster, and
found a problem when importing my VMs from an export domain.
Import is OK but can't start the VM due to the fact that the BIOS is set
to Legacy. Manually setting the BIOS type to Cluster Default, through VM
properties, will let the VM start.
I couldn't find anything about it in the ReleaseNotes
As a side note: using gluster still doesn't install
gluster-ansible-roles and glusterfs-server and vdsm-gluster or checks
for its existance. See also another user who reported problems due to
the latter not being installed, had the same experience.
Regards,
Joop

Recuring error in the Administration Portal
by Krist van Besien
When using the Administration Portal after a while I start to get errors like this:
'Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'isEval' of undefined
Please have your administrator check the UI logs'
'Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : null is not an object (evaluating 'b.b.b.a')
Please have your administrator check the UI logs'
These errors appear when I use Brave, but also appear after a while in Firefox, Chrome or Safari. The count listed in the upper right corner continuously increases if I do nothing.
I find these errors in the ui.log as well: For example:

What is going on? A bug? A misconfiguration? Database corruption?
This is an ovirt 4.4 cluster I setup on Centos 8. The cluster uses gluster storage, and was setup only a few days ago.

Which VLANs changed during the reboot of the host?
Just the VLANs on the hosts NICs, in a way the VMs are still connected to
the correct VLANs?

It is possible to run a network configuration, which does not persist and

Please find more details in
http://ovirt.github.io/ovirt-engine-api-model/master/#services/host/metho...
or the
"Save network configuration" checkbox in the "Setup Host Networks" dialog.
In recent oVirt versions this checkbox cannot be unselected anymore to
avoid unexpected situations.

If a virtual NIC is connected to a logical network with a VLAN tag, there
is no intended way for the VM to modify this tag.

VM Networking
by Anton Louw
Hi Everybody,
I had a strange incident today.. One of my nodes restarted (Still busy investigating why), but my VMs powered own and moved to different nodes, the only issue is, it seemed to have changed the vlan ID on the NICs? Has anybody seen this before? I am just trying to establish if this was changed on the node networking side, or inside of the VM.
Thank you

Problem with oVirt 4.4
by minnie.du＠vinchin.com
Hello,
We have met a problem when testing oVirt 4.4.
Our VM is on NFS storage. When testing the snapshot function of oVirt 4.4, we created snapshot 1 and then snapshot 2, but after clicking the delete button of snapshot 1, snapshot 1 failed to be deleted and the state of corresponding disk became illegal. Removing the snapshot in this state requires a lot of risky work in the background, leading to the inability to free up snapshot space. Long-term backups will cause the target VM to create a large number of unrecoverable snapshots, thus taking up a large amount of production storage. So we need your help.

Problems creating bricks for new Gluster storage 4.4
by Jaret Garcia
Hi guys I'm trying to deploy a new ovirt environmet based in version 4.4 so I set up the following:
1 engine sever (stand alone) Version : 4.4.0.3
3 host servers (32 GB RAM, 2CPUs 8 core Xeon 5160, 500GB OS drive, 1 storage 8TB drive and 1 SSD 256GB (I'm trying to create a brick with SSD cache with no success)
Detail of versions running on servers
[
OS Version:
RHEL - 8 - 1.1911.0.9.el8
OS Description:
oVirt Node 4.4.0
Kernel Version:
4.18.0 - 147.8.1.el8_1.x86_64
KVM Version:
4.1.0 - 23.el8.1
LIBVIRT Version:
libvirt-5.6.0-10.el8
VDSM Version:
vdsm-4.40.16-1.el8
SPICE Version:
0.14.2 - 1.el8
GlusterFS Version:
glusterfs-7.5-1.el8
CEPH Version:
librbd1-12.2.7-9.el8
Open vSwitch Version:
openvswitch-2.11.1-5.el8
Nmstate Version:
nmstate-0.2.10-1.el8
]
Engine server working fine, all 3 host servers already part of the default cluster as hypervisors, then when I try to create a brick in any of the servers, using the 8TB HHDD and SSD as cache the process fails, in the GUI it just says "failed to creat brick on host"
However in engine log as well as in brick-setup log I see: "err" : " Physical volume \"/dev/sdc\" still in use\n" "failed" : true,, (sdc in this case is the 8TB HHDD)
Attached files of both logs.
Thanks in advance,
Jaret Garcia

Mixing OS versions
by Stack Korora
Greetings,
We've been using Scientific Linux 7 quite successfully with oVirt for
years now. However, since there will not be a SL7 we are transitioning
new servers to CentOS8. I would like to add a new oVirt hypervisor node.
How bad of an idea is it to have a 8 system when the rest are 7 even
though the version of oVirt will be the same?
Thanks!
