routing table and wrong ip rule attribution on hosts
by Nathanaël Blanchet
Hi all,
I 've finished migration from 4.4.4 to 4.4.9 and I'm facing a strange
issue with routing table on my hosts: all IP addressed interfaces (and
in particular gluster and migration ones that requiere an IP) are not
part of the "254" or "0" usual ip rule.
for instance:
[root@fuego ~]# nmcli con sh gluster |grep ipv4.route-table
ipv4.route-table: 202179335
[root@fuego ~]# nmcli con sh migration |grep ipv4.route-table
ipv4.route-table: 316605387
but ovirtmgmt:
[root@fuego ~]# nmcli con sh ovirtmgmt |grep ipv4.route-table
ipv4.route-table: 254 (main)
and obviously the main route table is empty:
[root@ ~]# ip ro
default via 10.34.100.65 dev ovirtmgmt proto dhcp metric 425
10.34.100.0/24 dev ovirtmgmt proto kernel scope link src 10.34.100.116
metric 425
None of the concerned hosts can ping each other on such interface, and
live migrations systematically fail.
This behaviour is new with 4.4.9 and I don't know if it is a new (and
not achevied) network feature introduced with centos stream to deal
network filtering packets.
A simple workaround would be "nmcli connection mod migration
ipv4.route-table 0 && nmcli con up migration", but I'd like to
understand why such strange (and unuseful ?) rule table are now
randomly attributed?

Updating hosted-engine from 4.4.5 to latest(4.4.9) fail with "DNF name '_get_key_for_package' is not defined"
by rene.purcell＠gmail.com
Hi! I'm having issue updating my nodes, normally I just clicked on them and update each of them without problem. I haven't updated since few months, now I'm unable to. So I checked the doc and saw that I probably should update my engine first so that's what I tried.
Info on my setup:
2 nodes
hosted-engine is ran as a vm on the same cluster
storage is hosted on a NFS share on my qnap.
I'm following the doc (https://www.ovirt.org/documentation/upgrade_guide/#updates-between-minor-...) Fast recap I've put hosted-engine in global maintenance mode, installed the latest ovirt-release44.rpm on engine, engine-upgrade-check, yum update ovirt\*setup\* and finally ran the engine-setup which did not complete successfully..
Here's the error I get:
[....]

I can't find more info in the log specified in the output, I understand there's something wrong with the list of packages the script try to load/update but can't find any bug reports or other people having this issue so I'm running out of idea..
Anybody have a solutions to try fixing this and complete my engine upgrade to 4.4.9?
Thanks a lot, have a great day!!

hosted engine vm not present
by Nathanaël Blanchet
Hello
I successfully migrated from HE 4.3.10 to HE 4.4.9, but I think I
commited a mistake:
The HostedEngine vm was running on the host (haboob) where I deployed
the upgrade path.
Everything was ok except that I deployed it on the wrong host (haboob).
So I live migrated the HostedEngine on the centos prexisting host
(kilimanjaro) and erase haboob. Then I reinstalled a new host (fuego) to
replace haboob. The HostedEngine is able to migrate between kilimajaro
and fuego but now the vm seems to not be seen by any host when doing:
[root@fuego ~]# hosted-engine --vm-status

When doing hosted-engine --console, it returns:
[root@fuego ~]# hosted-engine --console

'74d2966c-2efa-41f0-a5c3-dd383f690a92'} failed:
(code=1, message=Virtual machine does not exist: {'vmId':
'74d2966c-2efa-41f0-a5c3-dd383f690a92'})
The engine VM is not on this host
It is like the vmID was the old 4.3.10 HostedEngine that doesn't exist
anymore.
How can I make the new HostedEngine vmID be the good one known by HA and
hosts?
*I'm afraid to lose the HostedEngine vm when stopping it!*
Thank you for your precious help.

Re: Creating VMs from templates with their own disks
by Strahil Nikolov
Yep.
Your code:
cloud_init:
custom_script: |
host_name: "{{ vm_fqdn }}"
user_name: myadmin
user_password: <password>
write_files:
- path: /tmp/setup.sh
permissions: '0755'
content: |
#!/bin/bash
echo "$(hostnamectl)" >> /tmp/myhostname.txt
Yet, in "custom_script" there is no "host_name" (indentation shows that host_name is part of the custom script, not to mention the "|" character).
Try with:
cloud_init:
host_name: "{{ vm_fqdn }}"
user_name: myadmin
# I can't find this one in https://docs.ansible.com/ansible/latest/collections/ovirt/ovirt/ovirt_vm_...
#user_password: <password>
root_password: <vaulted_password>
custom_script: |
write_files:
- path: /tmp/setup.sh
permissions: '0755'
content: |
#!/bin/bash
echo "$(hostnamectl)" >> /tmp/myhostname.txt

These should be part of the cloud-init dictionary and are strict about indentation.

Attaching LVM logical volume to VM
by th3penguinwhisperer＠gmail.com
Hi,
I've just migrated from Libvirt/kvm to oVirt.
In libvirt I had a VM that had an LVM logical volume that was attached to a guest as a disk.
However in oVirt I can't immediately find such a capability. I understand that this would "pin" my VM to this host but that's perfectly fine.
Any pointers how this can be done?
Thanks in advance!

Hosted Engine Deploy Failure

The other option is to create a cloned VM and this will copy the Templates disk to the VM so it's no longer dependent.
