Cinderlib RBD ceph template issues
by Sketch
This is on oVirt 4.4.8, engine on CS8, hosts on C8, cluster and DC are
both set to 4.6.
With a newly configured cinderlib/ceph RBD setup. I can create new VM
images, and copy existing VM images, but I can't copy existing template
images to RBD. When I do, I try, I get this error in cinderlib.log (see
below), which sounds like the disk already exists there, but it definitely
does not. This leaves me unable to create new VMs on RBD, only migrate
existing VM disks.

Import an exported VM using Ansible
by paolo＠airaldi.it
Hello everybody!
I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook.
I'm able to:
- Create a snapshot of the source VM
- create a clone from the snapshot
- remove the snapshot
- attach an Export Domain
- export the clone to the Export Domain
- remove the clone
- detach the Export domain from the source Datacenter and attach to the destination.
Unfortunately I cannot find a module to:
- import the VM from the Export Domain
- delete the VM image from the Export Domain.
Any hint on how to do that?
Thanks in advance. Cheers.
Paolo
PS: if someone is interested I can share the playbook.

did 4.3.9 reset bug https://bugzilla.redhat.com/show_bug.cgi?id=1590266
by kelley bryan
I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log
{2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

The bug 1590266 says it should report the engine VM IP address xxx.xxx.xxx.xxx while the Engines he_fqdn is xxxxxxxxx
I need to see what it thins is wrong as both dig fqdn engine name and dig -x ip return the correct information.
Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431
or is it because the vm fails or dies or ???

After upgrade to vdsm-4.40.90.4-1.el8 - Internal JSON-RPC error - how to fix?
by John Mortensen
Hi,
After we upgraded to vdsm-4.40.90.4-1.el8 on our two node cluster two things has happned:
1. First node that was upgraded now continuously logs this error:
VDSM <node name> command Get Host Statistics failed: Internal JSON-RPC error: {'reason': "'str' object has no attribute 'decode'"}
2. During import of two virtual machines from VMware (has done multible before upgrade) the import seems to never finish - currently running on day 2-3... any clues how to fix this?

Suggested upgrading path from CentOS based 4.4.8 to 4.4.9
by Gianluca Cecchi
I have a lab with an environment based on 4.4.8.6-1, with 3 CentOS Linux
8.4 hosts and a CentOS 8.4 external engine system (that is a VM on vSphere,
so that I can leverage a snapshot methodology for the process...).
I would like to pass to 4.4.9 and retain a full plain OS on hosts for the
moment, without going through oVirt nodes, but standing the repo problems
and CentOS 8.x going through EOL this is what I'm planning to do:
1. stop engine service on engine system
2. convert engine to CentOS Stream
This step needs some confirmation.
Could you provide an official link about the process?
I'm not able to find it again. Is it a problem of mine or all (CentOS
website, RHEL website) seem to point only to conversion from CentOS Linux
to RHEL??
Apart external websites provided workflows, I was only able to find a mid
January youtube video, when CentOS was based on 8.3, with these steps:
yum install centos-release-stream
yum swap centos-{linux,stream}-repos
yum repolist
yum distro-sync
reboot
The video link is here:
https://www.youtube.com/watch?v=Ba2ytp_8x7s
No mention at
https://www.redhat.com/en/blog/faq-centos-stream-updates
And on CentOS page I only found this:
https://centos.org/distro-faq/
with Q7 containing only the two instructions:
dnf swap centos-linux-repos centos-stream-repos
dnf distro-sync
What to use safely?
Is it possible to include some sort of documentation or links on oVirt
page, to migrate from CentOS Linux to CentOS Stream for oVirt upgrade
purposes?
3. After reboot implied, I think, in step 2., use the usual steps to update
engine to 4.4.9
4. update the first out of three hosts from CentOS Linux to CentOS Stream
and to 4.4.9.
4.a follow the same approach of engine (when defined) and pass it to Stream
retaining the 4.4.8.
4.b upgrade from the web admin gui to 4.4.9
5. Do the same for second host and third hosts
Any hints, comments, limitations in having mixed 4.4.8 and 4.4.9 hosts for
a while and such?
Thanks,
Gianluca

[FOSDEM][CFP] Virtualization & IaaS Devroom
by Piotr Kliczewski
We are excited to announce that the call for proposals is now open for the
Virtualization & IaaS devroom at the upcoming FOSDEM 2022, to be hosted
virtually on February 5th 2022.
This year will mark FOSDEM’s 22nd anniversary as one of the longest-running
free and open source software developer events, attracting thousands of
developers and users from all over the world. Due to Covid-19, FOSDEM will
be held virtually this year on February 5th & 6th, 2022.
About the Devroom
The Virtualization & IaaS devroom will feature session topics such as open

bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as
KubeVirt, Apache CloudStack, Foreman, OpenStack, oVirt, QEMU and OpenNebula.
This devroom will host presentations that focus on topics of shared
interest, such as KVM; libvirt; shared storage; virtualized networking;
cloud security; clustering and high availability; interfacing with multiple
hypervisors; hyperconverged deployments; and scaling across hundreds or
thousands of servers.
Presentations in this devroom will be aimed at users or developers working
on these platforms who are looking to collaborate and improve shared
infrastructure or solve common problems. We seek topics that encourage
dialog between projects and continued work post-FOSDEM.

Upgraded to oVirt 4.4.9, still have vdsmd memory leak
by Chris Adams
I have seen vdsmd leak memory for years (I've been running oVirt since
version 3.5), but never been able to nail it down. I've upgraded a
cluster to oVirt 4.4.9 (reloading the hosts with CentOS 8-stream), and I
still see it happen. One host in the cluster, which has been up 8 days,
has vdsmd with 4.3 GB resident memory. On a couple of other hosts, it's
around half a gigabyte.
In the past, it seemed more likely to happen on the hosted engine hosts
and/or the SPM host... but the host with the 4.3 GB vdsmd is not either
of those.
I'm not sure what I do that would make my setup "special" compared to
others; I loaded a pretty minimal install of CentOS 8-stream, with the
only extra thing being I add the core parts of the Dell PowerEdge
OpenManage tools (so I can get remote SNMP hardware monitoring).
When I run "pmap $(pidof -x vdsmd)", the bulk of the RAM use is a single
anonymous block (which I'm guessing is just the python general memory
allocator).
I thought maybe the switch to CentOS 8 and python 3 might clear
something up, but obviously not. Any ideas?
