Unable to upgrade ovirt-engine 3.5.5 to 3.6.1 on EL6
Hi, I've just tried to upgrade my ovirt-engine 3.5.5 which is still running on EL6, but it failed due to a dependency error regarding slf4j: # engine-setup [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup Configuration files: ['/etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf', '/etc/ovirt-engine-setup.conf.d/10-packaging.conf', '/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf'] Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20151231233407-lmovl5.log Version: otopi-1.4.0 (otopi-1.4.0-1.el6) [ INFO ] Stage: Environment packages setup [ INFO ] Stage: Programs detection [ INFO ] Stage: Environment setup [ INFO ] Stage: Environment customization --== PRODUCT OPTIONS ==-- --== PACKAGES ==-- [ INFO ] Checking for product updates...

Not really true - fake_kvm_support enables QEMU emulation instead of hardware virtualization (e.g. VT-x) instructions. It is also quite broken in it's current state and fix is pending in cpuinfo branch at gerrit. I don't really understand the reason why fake_kvm would be used in this case as AMD-v is enabled according to svm flag present - following instructions should be correct for getting the flag passed to the VMs.

Hi all, OK, it seems I am confused. Nested KVM is NOT the same as fake KVM.... If so, I installed vdsm-hook-nestedvt on the hypervisor (only). Trying to run ovirt-Node on a VM it complains there 's no virtualization, despite the kvm_amd module is loaded with nested=1 How to enable nested-kvm for oVirt 3.6?

How to enable nested-kvm for oVirt 3.6?
First, make sure that you're enabling the nested feature for amd (just noticed that the example used intel). Please show us the output of # cat /sys/module/kvm_intel/parameters/nested on the host (physical machine), lscpu inside the VM and VM XML - use # virsh -r list # virsh -r dumpxml {machine_id found in the list} Thanks, mpolednik

Hi,
I've just tried to upgrade my ovirt-engine 3.5.5 which is still running on EL6, but it failed due to a dependency error regarding slf4j:

I've followed the upgrade guide [1], and yes, I'm aware that AiO is no longer supported on EL6 [2], but this is just my Hosted-Engine VM, *not* an AiO host. So I thought it would still work.
I haven't attached any further logs, because this error is really obvious I guess. These are the currently installed oVirt packages:

Nobody's using EL6 anymore? :) I'd switch my Hosted-Engine VM to EL7 if it wouldn't be such a pain. The only "Upgrade Guide" I could find for Engine VM is this: http://www.ovirt.org/OVirt_Hosted_Engine_Backup_and_Restore No fun. :( FWIW, my oVirt nodes are all running EL7. Regards - Frank

On the contrary - in RHEV we still support only el6 for the engine: https://bugzilla.redhat.com/show_bug.cgi?id=1195123 I still didn't try to reproduce your failure, no idea. It should work. Perhaps to aid debugging you can try this, but _do_not_ press Enter: yum --disableplugin=versionlock update ovirt-engine Kill it (or reply 'no'). What does it output?

Thanks for the pointer. And... well, sorry for wasting your time. It was not working for me due to my yum-priorities configuration. Actually this was the very first time yum-priorities bit me. I guess it was the first time that a centos-base package was replaced by oVirt, too. Normally I wouldn't allow (or expect) any repo to replace a "base" package, thus my yum-priorities configuration. :) I've fixed the priorities for the oVirt repositories to be higher than the CentOS repositories, and now everything is working as expected. Maybe this should be added to the oVirt 3.6 errata (for EL6). Thanks - Frank

Didn't try that myself, but I think it should work. It only deals with the engine, though. Whatever other stuff you had on the engine machine, including an iso domain, extra packages/services/conf/etc., you'll have to recreate (or copy if relevant). -- Didi
