upgrading from 3.6 -> 4.1, vm restarts at 4.0 mandatory?
by Darrell Budic 26 Feb '17

26 Feb '17

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 26 Feb '17

26 Feb '17

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 Manuel

Restoring Hosted Engine to failed
by Logan Kuhn 26 Feb '17

26 Feb '17

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-engi… 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 Logan

ovirt 4.1.0.4 error..
by Thomas Davis 26 Feb '17

26 Feb '17

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.. thomas

Recognize HE iSCSI volume size change
by Chris Adams 24 Feb '17

24 Feb '17

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? -- Chris Adams <cma(a)cmadams.net>

Two Problems On New Install
by Charles Tassell 24 Feb '17

24 Feb '17

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 _attachLibvirtDomainAfterMigration 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 during reading data: unexpected eof Which I can't seem to diagnose. Any ideas?

import from Oracle VM possible?

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 10.4.168.74 port 54792 ssh2 Feb 23 15:22:25 oracle_vm_host sshd[25710]: Connection closed by 10.4.168.74 What I'm doing wrong here?

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, Gianluca
