USB3 redirection
by Rik Theys
Hi,
I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1
with USB redirection enabled.
I've created the following file in /etc/ovirt-engine/osinfo.conf.d:
01-usb.properties with content
os.other.devices.usb.controller.value = nec-xhci
and have restarted ovirt-engine.
If I disable USB-support in the web interface for the VM, the xhci
controller is added to the VM (I can see it in the qemu-kvm
commandline), but usb redirection is not available.
If I enable USB-support in the UI, no xhci controller is added (only 4
uhci controllers).
Is there a way to make the controllers for usb redirection xhci controllers?
Regards,
Rik

OVN routing and firewalling in oVirt
by Gianluca Cecchi
Hello,
how do we manage routing between different OVN networks in oVirt?
And between OVN networks and physical ones?
Based on architecture read here:
http://openvswitch.org/support/dist-docs/ovn-architecture.7.html
I see terms for logical routers and gateway routers respectively but how to
apply to oVirt configuration?
Do I have to choose between setting up a specialized VM or a physical one:
is it applicable/advisable to put on oVirt host itself the gateway
functionality?
Is there any security policy (like security groups in Openstack) to
implement?
Thanks,
Gianluca

Install hosted-engine - Task Get local VM IP failed
by florentl
Hi all,
I try to install hosted-engine on node : ovirt-node-ng-4.2.3-0.20180518.
Every times I get stuck on :
[ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed":
true, "cmd": "virsh -r net-dhcp-leases default | grep -i
00:16:3e:6c:5a:91 | awk '{ print $5 }' | cut -f1 -d'/'", "delta":

"stdout": "", "stdout_lines": []}
I tried with static IP Address and with DHCP but both failed.
To be more specific, I installed three nodes, deployed glusterfs with
the wizard. I'm in a nested virtualization environment for this lab
(Vmware Esxi Hypervisor).
My node IP is : 192.168.176.40 / and I want the hosted-engine vm has
192.168.176.43.
Thanks,

Host needs to be reinstalled after configuring power management
by Andrew DeMaria
Hi,
I am running ovirt 4.3 and have found the following action item immediately
after configuring power management for a host:
Host needs to be reinstalled as important configuration changes were
applied on it.
The thing is - I've just freshly installed this host and it seems strange
that I need to reinstall it.
Is there a better way to install a host and configure power management
without having to reinstall it after?
Thanks,
Andrew

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?

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 "ovn-ddecf0-0"

Port br-int
Interface br-int
type: internal
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. :)
