[Users] oVirt 3.4 test day - Template Versions
by Federico Simoncelli 27 Jan '14

27 Jan '14

Feature tested: http://www.ovirt.org/Features/Template_Versions - create a new vm vm1 and make a template template1 from it - create a new vm vm2 based on template1 and make some changes - upgrade to 3.4 - create a new template template1.1 from vm2 - create a new vm vm3 from template1 (clone) - content ok - create a new vm vm4 from template1.1 (thin) - content ok - create a new vm vm5 from template1 last (thin) - content ok (same as 1.1) - try to remove template1 (failed as template1.1 is still present) - try to remove template1.1 (failed as vm5 is still present) - create a new vm vm6 and make a template blank1.1 as new version of the blank template (succeeded) - create a vm pool vmpool1 with the "latest" template from template1 - create a vm pool vmpool2 with the "template1.1" (last) template from template1 - start vmpool1 and vmpool2 and verify that the content is the same - create a new template template1.2 - start vmpool1 and verify that the content is the same as latest (template1.2) - start vmpool2 and verify that the content is the same as template1.1 Suggestions: - the template blank is special, I am not sure if allowing versioning may be confusing (for example is not even editable) - as far as I can see the "Sub Version Name" is not editable anymore (after picking it) -- Federico

[Users] Hosted-engine runtime issues (3.4 BETA)
by Frank Wall 27 Jan '14

27 Jan '14

Hi, finally I've got the new hosted-engine feature running on RHEL6 using oVirt 3.4 BETA/nightly. I've come across a few issues and wanted to clarify if this is the desired behaviour: 1.) hosted-engine storage domain not visible in GUI The NFS-Storage I've used to install the hosted-engine is not visible in oVirt's Admin Portal. Though it is mounted on my oVirt Node below /rhev/data-center/mnt/. I tried to import this storage domain, but apparently this fails because it's already mounted. Is there any way to make this storage domain visible? 2.) hosted-engine VM device are not visible in GUI The disk and network devices are not visible in the admin portal. Thus I'm unable to change anything. Is this intended? If so, how am I supposed to make changes? 3.) move hosted-engine VM to a different storage Because of all of the above I seem to be unable to move my hosted-engine VM to a different NFS-Storage. How can this be done? Thanks - Frank

[Users] Cluster compatibility
by Piotr Kliczewski 27 Jan '14

27 Jan '14

I wanted to install two hosts one on f19 and the second on el6. I created additional cluster for el6. Host installation for el6 worked well and it joined the cluster without any issues. Whereas host in f19 was successfully deployed but it failed to join the cluster due to: Host fedora is compatible with versions (3.0,3.1,3.2,3.3) and cannot join Cluster Default which is set to version 3.4. Here are the versions that I use: engine: Name : ovirt-engine Arch : noarch Version : 3.4.0 Release : 0.5.beta1.fc19 Size : 1.5 M Repo : installed >From repo : ovirt-3.4.0-prerelease fedora host: Name : vdsm Arch : x86_64 Version : 4.14.1 Release : 2.fc19 Size : 2.9 M Repo : installed >From repo : ovirt-3.4.0-prerelease el6 host: Name : vdsm Arch : x86_64 Version : 4.14.1 Release : 2.el6 Size : 2.9 M Repo : installed >From repo : ovirt-3.4.0-prerelease Both clusters are set to be compatible with 3.4. Is there anything that I am missing? Piotr

Hi, Seem to be suffering an issue in 3.4 where if a vm is rebooted it actually shuts down, this occurs for all guests regardless of OS installed within. Anyone seen this? Jon

[Users] Issues starting hosted engine VM
by Andrew Lau 27 Jan '14

27 Jan '14

Hi, With the great help from sbonazzo, I managed to step past the initial bug with the hosted-engine-setup but appear to have run into another show stopper. I ran through the install process successfully up to the stage where it completed and the engine VM was to be shutdown. (The engine has already been installed on the VM and the host has been connected to the engine). The issue starts here that the host finds itself not able to start the VM up again. VDSM Logs: http://www.fpaste.org/69592/00427141/ ovirt-hosted-engine-ha agent.log http://www.fpaste.org/69595/43609139/ It seems to keep failing to start the VM.. when I restart the agent I can see the score drop to 0 after 3 boot attempts. The interesting thing seems to be in the VDSM Logs "'Virtual machine does not exist', 'code': 1}}" I'm not sure where else to look. Suggestions? Cheers, Andrew

[Users] Power saving cluster policy (3.4 test day)
by Lior Vernia 27 Jan '14

27 Jan '14

Hello, Just wanted to drop a line here about this feature I tested last week, which I thought was cool. I only tested it with two hosts and a single VM, using one of the hosts as a reserve, but it was quite satisfying to see the hosts being powered off and on as the VM was being run and stopped. This could be interesting to look at for those of you running a moderately-sized deployment, if often the load on your hosts is low. Yours, Lior.

[Users] sanlock leases on VM disks
by José Luis Sanz Boixader 27 Jan '14

27 Jan '14

I have an oVirt testing setup with 3 hosts running for a few weeks: CentOS 6.4, oVirt 3.3.1, VDSM 4.13.0, iSCSI based storage domain. I have just realized that sanlock has no leases on VM disks, so nothing prevents vdsm/libvirt from starting a VM on two different hosts, corrupting disk data. I know that something has to go wrong on oVirt engine to do it, but I've manually forced some errors ("Setting Host state to Non-Operational", "VM xxxx is not responding") for a "Highly available" VM and oVirt engine started that VM on another host. oVirt engine was not aware, but the VM was running on two hosts. I think this is a job for libvirt/sanlock/wdmd, but libvirt is not receiving "lease" tags for disks when creating domains. I think it should. What's left in my config? What am I doing wrong? Thanks

[Users] oVirt 3.4 test day: iscsi multipath
by Francesco Romani 27 Jan '14

27 Jan '14

Hi everyone, During the last oVirt 3.4 test day I played a bit with ISCSI multipath: http://www.ovirt.org/Feature/iSCSI-Multipath#Configure_iSCSI_Multipathing It took me longer than expected to properly set up things but, once done, everything looked fine at the config level (both seen from engine and the actual OS configuration) and worked well on my tests, including physical disconnections mid-I/O. Well done! :) -- Francesco Romani RedHat Engineering Virtualization R & D IRC: fromani
