One RHEV Virtual Machine does not Automatically Resume following Compellent SAN Controller Failover
by Duckworth, Douglas C 30 May '16

30 May '16

Hello -- Not sure if y'all can help with this issue we've been seeing with RHEV... On 11/13/2015, during Code Upgrade of Compellent SAN at our Disaster Recovery Site, we Failed Over to Secondary SAN Controller. Most Virtual Machines in our DR Cluster Resumed automatically after Pausing except VM "BADVM" on Host "BADHOST." In Engine.log you can see that BADVM was sent into "VM_PAUSED_EIO" state at 10:47:57: "VM BADVM has paused due to storage I/O problem." On this Red Hat Enterprise Virtualization Hypervisor 6.6 (20150512.0.el6ev) Host, two other VMs paused but then automatically resumed without System Administrator intervention... In our DR Cluster, 22 VMs also resumed automatically... None of these Guest VMs are engaged in high I/O as these are DR site VMs not currently doing anything. We sent this information to Dell. Their response: "The root cause may reside within your virtualization solution, not the parent OS (RHEV-Hypervisor disc) or Storage (Dell Compellent.)" We are doing this Failover again on Sunday November 29th so we would like to know how to mitigate this issue, given we have to manually resume paused VMs that don't resume automatically. Before we initiated SAN Controller Failover, all iSCSI paths to Targets were present on Host tulhv2p03. VM logs on Host show in /var/log/libvirt/qemu/badhost.log that Storage error was reported: block I/O error in device 'drive-virtio-disk0': Input/output error (5) block I/O error in device 'drive-virtio-disk0': Input/output error (5) block I/O error in device 'drive-virtio-disk0': Input/output error (5) block I/O error in device 'drive-virtio-disk0': Input/output error (5) All disks used by this Guest VM are provided by single Storage Domain COM_3TB4_DR with serial "270." In syslog we do see that all paths for that Storage Domain Failed: Nov 13 16:47:40 multipathd: 36000d310005caf000000000000000270: remaining active paths: 0 Though these recovered later: Nov 13 16:59:17 multipathd: 36000d310005caf000000000000000270: sdbg - tur checker reports path is up Nov 13 16:59:17 multipathd: 36000d310005caf000000000000000270: remaining active paths: 8 Does anyone have an idea of why the VM would fail to automatically resume if the iSCSI paths used by its Storage Domain recovered?

Re: [ovirt-users] oVirt 3.6 with ScaleIO

------=_Part_1525593_163252864.1464535747326 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit Thank you, Gianluca. The OpenStack integration with ScaleIO absolutely warrants further investigation on my part. It looks like a rather recent addition to ScaleIO, so I'll need to run that in a lab setting for a while. It looks like the best long term option. In the meantime, I think that I might be able to get this working by exposing a few, larger LUNs via NFS running on the ScaleIO nodes. I lose granular snapshot capabilities and MPIO in ScaleIO that way, though. If I need real MPIO-type performance on a VM, I guess I can just install the ScaleIO client in the guest and access the LUN that way. Also, I plan on learning more about the iSCSI Direct LUN logic in oVirt to see if there is enough similarity between the output of iscsiadm and the ScaleIO SDC/SDS utilities to request a direct ScaleIO integration feature. That might be a nice little side project for a while.

I was thinking that I would just set up iSCSI LUNs in ScaleIO and have oVirt point directly to one for the hosted engine setup. From there, my plan was to assign disks to VMs as direct LUNs. Unfortunately, it looks like ScaleIO dropped iSCSI support at around version 1.32 and I'm at a loss as to how I can expose ScaleIO LUNs to oVirt.

Changing Cluster CPU Type in a single Host with Hosted Engine environment
by Ralf Braendli 28 May '16

28 May '16

Hi I have the Problem that I selected the wrong CPU Type throw the setup process. Is it posible to change it without an new installation ? We have a single Host with a Hosted Engine installed. With this installation I can’t put the Host into Maintenance Mode because the Hosted Engine will run on this Host. The Version we us is 3.5.5-1 Best Regards Ralf Brändli

How to automate the ovirt host deployment?

27 May '16

Hi, I am looking some method to automate the host deployments in a cluster environment. Assuming we have 20 nodes with centos 7 eth0/eth1 configured. Is it possible to automate installation with ovirt-sdk? Are there some examples ? Thanks, Arman.

Problem upgrading Host from 3.5 to 3.6 in Centos 6
by Giulio D’Ippolito 27 May '16

27 May '16

Hi all, We are having a bit of hard time trying to upgrade oVirt from 3.5 release to 3.6. This is our setup: - All the hosts are running Centos 6.7 - The engine is a standalone machine - The engine is running Centos 6.7 - Upgrading the engine from 3.5.x to 3.6.6 was successful Now the problem was when we were trying to upgrade the hosts to 3.6 release. We put one host in maintenance and we were expecting the "Upgrade" option to be available but it wasn't. We have imported the 3.6 repository to the host and performed a "yum clean all" and a "yum update" to see which packages were marked to be upgrade. No packages in the oVirt 3.6 repository were available to upgrade. Then we tried to use the "Reinstall" option available in the GUI The reinstall failed with the following issue: *2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum queue package qemu-kvm-tools for install2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum processing package 2:qemu-kvm-tools-0.12.1.2-2.491.el6_8.1.x86_64 for install2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum package 2:qemu-kvm-tools-0.12.1.2-2.491.el6_8.1.x86_64 queued2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum queue package vdsm for install/update2016-05-27 09:46:51 DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum queue package vdsm-cli for install/update2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:142 Stage packages METHOD otopi.plugins.ovirt_host_deploy.vdsmhooks.hooks.Plugin._packages2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:142 Stage packages METHOD otopi.plugins.ovirt_host_deploy.vmconsole.packages.Plugin._packages2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:148 condition False2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:142 Stage packages METHOD otopi.plugins.otopi.packagers.dnfpackager.Plugin._packages2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:148 condition False2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:142 Stage packages METHOD otopi.plugins.otopi.packagers.yumpackager.Plugin._packages2016-05-27 09:46:51 DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum Building transaction2016-05-27 09:46:52 ERROR otopi.plugins.otopi.packagers.yumpackager yumpackager.error:100 Yum ['qemu-kvm-rhev-tools conflicts with 2:qemu-kvm-tools-0.12.1.2-2.491.el6_8.1.x86_64']* We fixed the issue via removing the qemu-kvm-tools and running the "Reinstall again". But effectively this was the only package that was installed/upgrade by running "Reinstall" again. I can see from the repository http://resources.ovirt.org/pub/ovirt-3.6/rpm/el6/x86_64/ that not many packages are available in this repository for Centos 6. For example vdsm package is still version vdsm-4.16.30-0.el6 which was installed in oVirt 3.5 Is this the expected outcome of the upgrade in the host? Thanks, Giulio
