My vdsm log files are huge:
-rw-r--r-- 1 vdsm kvm 1.8G Nov 22 11:32 vdsm.log
And this is juste half an hour of logs:
$ head -1 vdsm.log
2018-11-22 11:01:12,132+0100 ERROR (mailbox-spm) [storage.MailBox.SpmMailMonitor] mailbox 2 checksum failed, not clearing mailbox, clearing new mail (data='...lots of data', expected='\xa4\x06\x08\x00') (mailbox:612)
I just upgraded vdsm:

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com
I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server.
I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template.
When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template.
It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue.
Has anyone else noticed this behavior? Is this expected or have I missed something?
Thanks for your input!

Libgfapi considerations
by Jayme
Are there currently any known issues with using libgfapi in the latest
stable version of ovirt in hci deployments? I have recently enabled it and
have noticed a significant (over 4x) increase in io performance on my vms.
I’m concerned however since it does not seem to be an ovirt default
setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

Hello, is there a way to poweroff or reboot (without stopped and running
state) a vm with the ovirt_vm ansible module?

supervdsm failing during network_caps
by Alan G
Hi,
I have issues with one host where supervdsm is failing in network_caps.
I see the following trace in the log.
MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps

A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind?
Running 4.2.8.2 with VDSM at 4.20.46.
I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix.
Thanks,

OVN and change of mgmt network
by Gianluca Cecchi
Hello,
I previously had OVN running on engine (as OVN provider with northd and
northbound and southbound DBs) and hosts (with OVN controller).
After changing mgmt ip of hosts (engine has retained instead the same ip),
I executed again on them the command:
vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host>
Now I think I have to clean up some things, eg:
1) On engine
where I get these lines below
systemctl status ovn-northd.service -l
. . .
Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp:
10.4.167.40:37272: no response to inactivity probe after 5 seconds,
disconnecting
Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp:
10.4.167.41:52078: no response to inactivity probe after 5 seconds,
disconnecting
The two IPs are the old ones of two hosts
It seems that a restart of the services has fixed...
Can anyone confirm if I have to do anything else?
2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34)
where I currently have this output
[root@ov301 ~]# ovs-vsctl show
3a38c5bb-0abf-493d-a2e6-345af8aedfe3
Bridge br-int

Port br-int

ovs_version: "2.7.2"
[root@ov301 ~]#
The IPs of kind 10.4.192.x are ok.
But there is a left-over of an old host I initially used for tests,
corresponding to 10.4.168.74, that now doesn't exist anymore
How can I clean records for 1) and 2)?
Thanks,
Gianluca

encrypted GENEVE traffic
by Pavel Nakonechnyi
Dear oVirt Community,
From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/).
Are there plans to introduce such support? (or explicitly not to..)
Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way)
Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic.
Such requirement arises when using oVirt deployment on third-party premises with untrusted network.
Thank in advance for any clarifications. :)

"gluster-ansible-roles is not installed on Host" error on Cockpit
by Hesham Ahmed
On a new 4.3.1 oVirt Node installation, when trying to deploy HCI
(also when trying adding a new gluster volume to existing clusters)
using Cockpit, an error is displayed "gluster-ansible-roles is not
installed on Host. To continue deployment, please install
gluster-ansible-roles on Host and try again". There is no package
named gluster-ansible-roles in the repositories:
[root@localhost ~]# yum install gluster-ansible-roles
Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist,
package_upload, product-id, search-disabled-repos,
subscription-manager, vdsmupgrade
This system is not registered with an entitlement server. You can use
subscription-manager to register.
Loading mirror speeds from cached hostfile
* ovirt-4.3-epel: mirror.horizon.vn
No package gluster-ansible-roles available.
Error: Nothing to do
Uploading Enabled Repositories Report
Cannot upload enabled repos report, is this client registered?
This is due to check introduced here:
https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js
Changing the line from:
[ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" }
to
[ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" }
resolves the issue. The above code snippet is installed at
/usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be
patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g'
/usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart
cockpit"

Or possibly implicit user session created when running the python script?

Any known problem?

How to extend timeout?
