Network Address Change
by Paul.LKW
Hi All:
I just has a case, I need to change the oVirt host and engine IP address
due to data center decommission I checked in the hosted-engine host
there are some files I could change ;
in ovirt-hosted-engine/hosted-engine.conf
ca_subject="O=simple.com, CN=1.2.3.4"
gateway=1.2.3.254
and of course I need to change the ovirtmgmt interface IP too, I think
just change the above line could do the tick, but where could I change
the other host IP in the cluster ?
I think I have to be lost all the host as once changed the hosted-engine
host IP as it is in diff. sub net.
Does there any command line tools could do that or someone has such
experience could share?
Best Regards,
Paul.LKW

OVS switch type for hosted-engine
by Devin A. Bougie
Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If it's not possible to start out as OVS, instructions for switching from Legacy to OVS after the fact would be greatly appreciated.
Many thanks,
Devin

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

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
fail_mode: secure
Port "ovn-1dce5b-0"

Port "ovn-ddecf0-0"
Interface "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,

deprecating export domain?
by Charles Kozler
Hello,
I recently read on this list from a redhat member that export domain is
either being deprecated or looking at being deprecated
To that end, can you share details? Can you share any notes/postings/bz's
that document this? I would imagine something like this would be discussed
in larger audience
This seems like a somewhat significant change to make and I am curious
where this is scheduled? Currently, a lot of my backups rely explicitly on
an export domain for online snapshots, so I'd like to plan accordingly
Thanks!

Vm suddenly paused with error "vm has paused due to unknown storage error"
by Jasper Siero
Hi all,
Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month.
The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems.
The vm runs without problems after unpausing it.

i have not moved my most important server over to this cluster yet so i
can take some downtime to reinstall.

[Users] Problem Creating "oVirtEngine" Machine
by Richie＠HIP

I can't agree with you more. Modifying every box's or Virtual Machine's =
HOSTS file with a FQDN and IP SHOULD work, but in my case it is not. =
There are several reasons I've come to believe could be the problem =
during my trial-and-errors testing and learning.
FIRST - MACHINE IPs.
THe machine's "Names" where not appearing in the Microsoft Active =
Directory DHCP along with their assigned IPs; in other words, the DHCP =
just showed an "Assigned IP", equal to the Linux Machine's IP, with a =
<empty> ('i.e. blank, none, silch, plan old "no-letters-or-numbers") =
"Name" in the "Name" (i.e. machines "network name", or FQDN-value used =
by the Windows AD DNS-service) column. =20
if your IP is is appearing with an <empty> "name", there is no "host =
name" to associate the IP, it makes it difficult to define a FQDN; which =
isn't that useful if we're going to use the HOSTS files in all =
participating machines in an oVirt Installation.
I kept banging my head for three (3) long hours trying to find the =
problem.
In Fedora 18, I could't find where the "network name" of the machine =
could be defined. =20
I tried putting the "Additional Search Domains" and/or "DHCP Client ID" =
in Fedora's 18 Desktop - under "System Settings > Hardware > Network > =
Options > IPv4 Setting"
The DHCP went crazy; showing an "Aberrant-MAC-Address" (i.e. a really =
long-sting value where the machine's MAC address should be), and we knew =
the MAC address as we obtained using "ifconfig" on the machine getting =
it's IP from the DHCP. So we reverted these entries from the =
aforementioned, rebooted, and got an assigned IP, with proper MAC =
address, but still no "Name"
Kept wondering around the "Settings" and seeing which one made sense, =
but what the heck, I went for it. =20
Under "System Settings > System > Details" I found the information about =
GNOME and the machine's hardware. =20
There was a field for "Device Name" that originally had =
"localhost.localdomain"; I changed the value to "ovirtmanager". and =
under "Graphic" changed to "Forced Fallback Mode" to "ON". =20
I also installed all Kerberos libraries and client (i.e. authconfig-gtk, =
authhub, authhub-client, krb5-apple-clents, krb5-auth-dialog, =
krb5-workstation, pam-kcoda, pam-krb5, root-net.krb5) and rebooted
VOILA=85!!! =20
I don;t know if it was the definition of "Device Name" from =
"localhost.localdomain" to "ovirtengine", of the Kerberos libraries =
install, or both. But finally the MS AD DHCP was showing the =
Addigned-IP, the machine "Name" and the proper MAC-address. Regardless, =
setting the machine's "Network Name" under "System Settings > System > =
Details > Device Name", with no explanation of what "Device Name" meant =
or was used for, was the last place I would have imagined this network =
setting could be defined.
NOTE - Somebody has to try the two steps I did together, separately. to =
see which one is the real problem-solver; for me it is working, and "if =
it ain't broke, don't fix it=85"
Now that I have the DHCP / IP thing sorted, I have to do the DNS stuff.
To this point, I've addressed the DHCP and "Network Name" of the =
IP-Lease (required for the DNS to work). This still does't completely =
explain why, by modifying the HOSTS file (allowing be to set and IP and =
non-DNS FQDN). allows me to install the oVirtEngine "as long as I do not =
use default HTTPd service parameters as suggested by the install". By =
using the HOST file to "define" FQDNs, AND NOT using the default HTTPd =
suggested changes, I'm able to install the oVirtEngine (given that I use =
ports 8700 and 8701) to access the "oVirtEngine Welcome Screen", BUT =
NONE of the "oVirt Portals" work=85 YET=85!!!
More to come during the week

the <b>Microsoft Active Directory DHCP</b> along with their assigned =
IPs; in other words, the DHCP just showed an "Assigned IP", equal to the =
Linux Machine's IP, with a <empty> ('i.e. blank, none, silch, plan =
old "no-letters-or-numbers") "Name" in the "Name" (i.e. machines =
"network name", or FQDN-value used by the Windows AD DNS-service) =
column. </li><li>if your IP is is appearing with an <empty> =
"name", there is no "host name" to associate the IP, it makes it =
difficult to define a FQDN; which isn't that useful if we're going to =
use the HOSTS files in all participating machines in an oVirt =
Installation.</li><li>I kept banging my head for three (3) long hours =
trying to find the problem.</li><ul><li>In Fedora 18, I could't find =
where the "network name" of the machine could be defined. =
</li><li>I tried putting the "Additional Search Domains" and/or =
"DHCP Client ID" in Fedora's 18 Desktop - under "System Settings > =
Hardware > Network > Options > IPv4 Setting"</li><ul><li>The =
DHCP went crazy; showing an "Aberrant-MAC-Address" (i.e. a really =
long-sting value where the machine's MAC address should be), and we knew =
the MAC address as we obtained using "ifconfig" on the machine getting =
it's IP from the DHCP. So we reverted these entries from the =
aforementioned, rebooted, and got an assigned IP, with proper MAC =
address, but still no "Name"</li></ul><li>Kept wondering around the =
"Settings" and seeing which one made sense, but what the heck, I went =
for it. </li><ul><li>Under "System Settings > System > =
Details" I found the information about GNOME and the machine's hardware. =
</li><li>There was a field for "Device Name" that originally had =
"localhost.localdomain"; I changed the value to "ovirtmanager". and =
under "Graphic" changed to "Forced Fallback Mode" to "ON". =
</li><li>I also installed all Kerberos libraries and client (i.e. =
authconfig-gtk, authhub, authhub-client, krb5-apple-clents, =
krb5-auth-dialog, krb5-workstation, pam-kcoda, pam-krb5, root-net.krb5) =
and rebooted</li><li>VOILA=85!!! </li></ul><li>I don;t know if it =
was the definition of "Device Name" from "localhost.localdomain" to =
"ovirtengine", of the Kerberos libraries install, or both. But =
finally the MS AD DHCP was showing the Addigned-IP, the machine "Name" =
and the proper MAC-address. Regardless, setting the machine's =
"Network Name" under "System Settings > System > Details =
> Device Name", with no explanation of what "Device Name" meant =
or was used for, was the last place I would have imagined this =
network setting could be defined.</li><li><b>NOTE</b> - Somebody has to =
try the two steps I did together, separately. to see which one is the =
real problem-solver; for me it is working, and "if it ain't broke, don't =
fix it=85"</li></ul></ul><div><br =

this point, I've addressed the DHCP and "Network Name" of the IP-Lease =
