Migrating to a Hosted Engine does not work as expected. Cluster name/id problem?
by Gustavo Campos 26 Apr '15

26 Apr '15

Hi, I've been trying for sometime to migrate from a bare metal to a hosted engine. Failed about 6-7 times now. Facts: - Ovirt Engine version is 3.4 - 6 hosts on a cluster named "MYCLUSTER", Westmere CPU Type - About 50 VM's on "MYCLUSTER" cluster. - NFS Storage domain - Cluster "Default" is empty: no hosts, no VM's, only the "Blank" template (I didn't know I could just rename it when I deployed it) The first times I tried to deploy it, the hosted-engine VM and host ended up in the "Default" cluster. So I renamed the "Default" cluster "Default1" and then "MYCLUSTER" to "Default" using the web gu on the bare metal manager, prior to generating the backup I later restored on the hosted one. This time, the host was correctly added to "Default" together with the other hosts and VM's, but the hosted engine VM was added to the "Default1" cluster. I'm then left with: - a HostedEngine VM which looks down on the engine, even though I'm looking at the web-gui running on it. - a host that shows 1 vm running on it, but have no Vm's listed - trying to do anything with the HostedEngine Vm on the web-gui issues "VM is not managed by this engine" error - trying to move it to the "Default" cluster shows the same error I then decided to take a look at the engine DB and tried to alter tables vm_static and vm_dynamic to reflect the correct cluster (vds_group_id) and host configuration, but that did not work (I didn't have a lot of hope anyway). I'm now back to a working bare metal engine. Is there a way to go around this problem? -- Gustavo Campos

Doubts about performance qcow2 and raw in newer versions of KVM
by Tácio Andrade 25 Apr '15

25 Apr '15

Staff would like to know if anyone here in the group has done a comparison between RAW and qcow2 discs to see if the performance loss is even as large as speak. I ask this because I saw on the KVM project site a comparative table, however is based on a version of qemu 2009 apparently, so I wonder if it is still valid or hear improvements in qcow2. http://www.linux-kvm.org/page/Qcow2 <https://mailtrack.io/trace/link/2cd1d17a672a9ef035e4ccde270c972ff570e5bd?ur…> Another doubt that I have with respect to this article, which he said is the IDE driver has outperformed virtio, the new version is so? I question this because I always read the virtio driver is the most suitable for an installation using KVM. Thank you in advance for help. Att.

Hi, I try a testsetup on a CentOS 6.6. I want to setup all on a single host so far. When I try to create a local storage on the host i got always the message "Error while executing action Add Storage Connection: General Exception" I trie the video howto in combination with the Quick Start Guide and http://www.ovirt.org/Feature/AllInOne I understand, that I've to generate a answer-file in cause of a bug for VDSM?

ManageIQ : Attach an already attached storage domain
by Nicolas Ecarnot 23 Apr '15

23 Apr '15

Hello, According to what I understood, ManageIQ VM appliance needs to attach to every storage domain it has to scan. 1 : I'm new to ManageIQ and the above is what I think I have understood from the answer of the ManageIQ team. If anyone here knows more about it, please comment. 2 : When trying to do the above, oVirt is showing red frightening warning, so I did not dare yet to approve. I intended to attach these LUNs in read only mode, hoping this checkbox will get respected. Once again, may the wisest users comment? Have a nice day. -- Nicolas Ecarnot
