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

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"
Interface "ovn-1dce5b-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.32"}
Port "ovn-ddecf0-0"
Interface "ovn-ddecf0-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.33"}

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

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.

CentOS Linux release 7.1.1503

Ovirt-engine-ha cannot to see live status of Hosted Engine
by asm＠pioner.kz
Good day for all.
I have some issues with Ovirt 4.2.6. But now the main this of it:
I have two Centos 7 Nodes with same config and last Ovirt 4.2.6 with Hostedengine with disk on NFS storage.
Also some of virtual machines working good.
But, when HostedEngine running on one node (srv02.local) everything is fine.
After migrating to another node (srv00.local), i see that agent cannot to check livelinness of HostedEngine. After few minutes HostedEngine going to reboot and after some time i see some situation. After migration to another node (srv00.local) all looks OK.

As we can see, agent thinking that HostedEngine just in powering up mode. I cannot to do anythink with it. I allready reinstalled many times srv00 node without success.
One time i even has to uninstall ovirt* and vdsm* software. Also here one interesting point, after installing just "yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm" on this node i try to install this node from engine web interface with "Deploy" action. But, installation was unsuccesfull, before i didnt install ovirt-hosted-engine-ha on this node. I dont see in documentation that its need bofore installation of new hosts. But this is for information and checking. After installing ovirt-hosted-engine-ha node was installed with HostedEngine support. But the main issue not changed.
Thanks in advance for help.

disk locked after export as OVA
by adam_xu＠adagene.com.cn
Hello, everyone. I tried to export a vm as OVA. I got a error in webui:
VDSM ovirt1.ntbaobei.com command HSMGetAllTasksStatusesVDS failed: Volume Group not big enough: (u'Not enough free extents for extending LV d9f2378f-92f0-4bc1-96a8-20a0f2c575cb/c515a3f9-0590-4ebe-81c5-9d0993f1fec9 (free=848, needed=872)',)
seems no enough space in the storage domain.
I deleted the vm which i wanted to export as OVA before, but I saw a disk with id 8140d2e7-6908-438e-a646-23e58a33913e left in the storage and the status is locked.
here's some log in the engine.log:

I think maybe some command did not been excuted after I export the vm as OVA. I can find the similar case here:
https://access.redhat.com/solutions/1298893
I have used the tool unlock_entity.sh but cannot find any disk that is locked.
So what should I do to delete the disk that is been locked?

Hi,
so i was running a 3.4 hosted engine two node setup on centos 6, had
some disk issues so i tried to upgrade to centos 7 and follow the path
3.4 > 3.5 > 3.6 > 4.0. i screwed up dig time somewhere between 3.6 and
4.0, so i wiped the drives, installed a fresh 4.0.3, then created the
database and restored the 3.6 engine backup before running engine-setup
as per the docs. things seemed to work, but i have the the following

I have searched a bit and not really found a solution, and have come to
the conclusion that i have made a mess of things, and am wondering if
the best solution is to export the VMs, and reinstall everything then
import them back?
i am using remote NFS storage.
if i try and add the hosted engine storage domain it says it is already
registered.
i have also upgraded and am now running oVirt Engine Version:
4.0.4.4-1.el7.centos
hosts were installed using ovirt-node. currently at
3.10.0-327.28.3.el7.x86_64
if a fresh install is best, any advice / pointer to doc that explains
best way to do this?
i have not moved my most important server over to this cluster yet so i
can take some downtime to reinstall.
thanks!

Unable to get vm.conf from OVF_STORE, falling back to initial
vm.conf<br>
<br>
I have searched a bit and not really found a solution, and have come
to the conclusion that i have made a mess of things, and am
wondering if the best solution is to export the VMs, and reinstall
everything then import them back?<br>
i am using remote NFS storage.<br>
if i try and add the hosted engine storage domain it says it is
already registered.<br>
i have also upgraded and am now running <span
class="gwt-InlineLabel">oVirt Engine Version: 4.0.4.4-1.el7.centos<br>
hosts were installed using ovirt-node. currently at
3.10.0-327.28.3.el7.x86_64<br>
if a fresh install is best, any advice / pointer to doc that
explains best way to do this?<br>
i have not moved my most important server over to this cluster yet
so i can take some downtime to reinstall.<br>
thanks!<br>

Any plans for oVirt and SBD fencing (a.k.a. poison pill)
by hunter86_bg＠yahoo.com
Hello Community,
Do you have any idea if SBD fencing mechanism will be implemented in the nearest future?
It will be nice to be able to resset a host just like corosync/pacemaker cluster implementation.

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
