upgrading from 3.6 -> 4.1, vm restarts at 4.0 mandatory?
by Darrell Budic
I’m upgrading my main cluster from 3.6 to 4.1, and I’m currently at 4.0. I’ve upgraded the cluster and datacenter compatibility versions to 4.0, and now all my VMs are pending restart to update their configs to 4.0.
My question is “Do I need to do this here, or can I go ahead and update the engine and host nodes to 4.1, update compatibility to 4.1, and then restart all the VMs to get them on 4.1”? Or is that unsafe, will I screw them up if I go to 4.1 compatibility in this state?
Thanks,
-Darrell

oVirt 4.1 Release Stops at Installing host on enrrolling serial console certificate
by Manuel Luis Aznar
Hello there,
I am doing a very litle installation at home, just with one machine (Asus
X99-E WS and Intel Core i7 6850K), all is fine until I reached the
installation of the host (adding host).
The web admin interface get stopped and the last event is Enrrolling Serial
Console Certificate and in few litle seconds the web admin interface stops
responding. To make the web admin interface back again I need to do
engine-cleanup and engine-setup...
Hope somebody can help me,
Thanks

Restoring Hosted Engine to failed
by Logan Kuhn
Hi
I'm in the process of trying to restore our previous hosted engine onto
new, permanent, storage. I've followed this guide:
https://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-en...
It went pretty smoothly up until the hosted engine deploy tried to add the
host to the environment. The error was Unable to add HEVM to the manager.
However, I can login to the environment just fine, but it does not have the
HEVM and the host it's currently running on is down.
I've attached the hosted engine setup log. Let me know if there are any
other logs that will be helpful

ovirt 4.1.0.4 error..
by Thomas Davis
I am getting this error message:
Unexpected character ('<' (code 60)): expected a valid value (number,
String, array, object, 'true', 'false' or 'null') at [Source:
java.io.StringReader@4c65dbb1; line: 1, column: 2]
in both screen after login on ovirt, and in the engine.log.
Any ideas one what it is looking for this?
This ovirt setup has gone from 3.5 -> 3.6 -> 4.0 -> 4.1.
I am currently blocked on doing any VM management in ovirt due to this..

Recognize HE iSCSI volume size change
by Chris Adams
I'm testing upgrading an oVirt 3.5 setup, and I have run into a problem
when going from 3.5 to 3.6 on a physical machine configured for the
hosted engine. I upgraded the engine itself okay, but when I upgraded
the first physical machine, it cannot be re-activated; it gets an error
connecting to the storage domain.
Checking the logs, it looks like it is looping trying to create a new LV
in the HE VG. I assume this is for moving the HE config to the shared
storage? It is failing because it is trying to create a 1G LV, but the
VG only has 512M free space.
I extended the iSCSI volume, but there doesn't appear to be anyway to
get the HE nodes to recognize this; they both still see the original
size, no matter what I try. Is there a way to get them to see the
larger PV, so the new LV(s) can be created?

Troubleshoot failed storage migration

I had an outage during live storage migration of a VM disk between two iSCS=

Since the outage prevented Ovirt to cleanly remove stuff on the destination=
iSCSI when the failure occurred, I think there's leftovers on the destinat=
ion iSCSI. The result is that any further attempt to live storage migrate t=
his VM disk fails with error "Cannot create Logical Volume"
How can I troubleshoot / fix this ?

Two Problems On New Install
by Charles Tassell
Hi Everyone,
I recently installed oVirt 4.0 on two servers with an iSCSI
backstore, and I'm having two issues I'm having trouble tracking down.
First, the initial datastore that the hosted engine is running on won't
connect. It just says "Unattached" in the GUI, and I can't find an
error message anywhere. Not a huge deal, it just means I can't see the
hosted engine itself in the GUI.
More importantly: I can't migrate VMs. They fail with errors like
this in the vdsm.log of the destination host:
Thread-60381::ERROR::2017-02-14
21:55:47,921::vm::767::virt.vm::(_startUnderlyingVm)
vmId=`59f235cc-3ab2-4dae-b460-62be850e3d5d`::Failed to start a migration
destination vm
Traceback (most recent call last):
File "/usr/share/vdsm/virt/vm.py", line 733, in _startUnderlyingVm
self._completeIncomingMigration()
File "/usr/share/vdsm/virt/vm.py", line 3113, in
_completeIncomingMigration
self._incomingMigrationFinished.isSet(), usedTimeout)
File "/usr/share/vdsm/virt/vm.py", line 3196, in

raise MigrationError(e.get_error_message())
MigrationError: Domain not found: no domain with matching uuid
'59f235cc-3ab2-4dae-b460-62be850e3d5d'
If I shut the VM down and start it on the host it works fine, it just
won't migrate. I notice I'm also seeing a lot (like every 7 seconds) of
this error:
JsonRpc (StompReactor)::ERROR::2017-02-14
21:57:33,984::betterAsyncore::113::vds.dispatcher::(recv) SSL error

Which I can't seem to diagnose. Any ideas?

import from Oracle VM possible?
by Gianluca Cecchi
Hello,
I'm just trying to see if I can import from Oracle VM a bunch of VMs.
I'm trying from gui in 4.1 using XEN (via RHEL) as Source and in URI I put
this
xen+ssh://root@oracle_vm_host
I use one of my oVirt hosts as proxy (ovmsrv05 with ip 10.4.168.74)
>From ovmsrv05 I verified I can ssh with public key and without password
input to the oracle_vm_host
But when I click the "Load" button in oVirt GUI, in /var/log/secure of
Oracle VM Host I get a series of these messages:
Feb 23 15:22:25 oracle_vm_host sshd[25707]: Failed password for root from
10.4.168.74 port 54792 ssh2
Feb 23 15:22:25 oracle_vm_host sshd[25707]: Failed password for root from

Feb 23 15:22:25 oracle_vm_host sshd[25710]: Connection closed by 10.4.168.74
What I'm doing wrong here?

ova conversion errors: where to search?
by Gianluca Cecchi
Hello,
testing some VMware ova imports.
In a test that I'm doing I get failure in conversion; in engine.log
2017-02-17 17:39:02,992+01 INFO
[org.ovirt.engine.core.bll.exportimport.ConvertVmCallback]

environment failed: Job u'cdb31877-3ebb-400d-88da-1f645b1261ae' process
failed exit-code: 1
where to find more details regarding reasons for failure? Other files on
engine or should I see at host side?
In case I have to import a windows VM ova, which iso should I attach near
the "Attach VirtIO-Drivers" checkbox? Any "official" iso? I
downloaded oVirt-toolsSetup-4.1-3.fc24.iso but I don't know if it is the
right iso for this.
Thanks,
