[ovirt-announce][ANN] oVirt 4.1.7 Second Release Candidate is now available
by Lev Veyde 28 Sep '17

28 Sep '17

The oVirt Project is pleased to announce the availability of the Second Release Candidate of oVirt 4.1.7, as of September 28th, 2017 This update is the seventh in a series of stabilization updates to the 4.1 series. Starting from 4.1.5 oVirt supports libgfapi [5]. Using libgfapi provides a real performance boost for ovirt when using GlusterFS . Due to a known issue [6], using this will break live storage migration. This is expected to be fixed soon. If you do not use live storage migration you can give it a try. Use [7] for more details on how to enable it. This release is available now for: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later * oVirt Node 4.1 See the release notes draft [3] for installation / upgrade instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available - oVirt Live is already available[4] - oVirt Node is already available[4] Additional Resources: * Read more about the oVirt 4.1.7 release highlights: http://www.ovirt.org/release/4.1. <http://www.ovirt.org/release/4.1.7/>7 <http://www.ovirt.org/release/4.1.7/>/ <http://www.ovirt.org/release/4.1.7/> * Get more oVirt Project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] https://www.ovirt.org/community/ [2] https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt [3] http://www.ovirt.org/release/4.1. <http://www.ovirt.org/release/4.1.7/>7 <http://www.ovirt.org/release/4.1.7/>/ <http://www.ovirt.org/release/4.1.7/> [4] http://resources.ovirt.org/pub/ovirt-4.1-pre/iso/ [5] http://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Features/lib… [6] https://bugzilla.redhat.com/show_bug.cgi?id=1306562 [7] http://www.ovirt.org/develop/release-management/features/storage/glusterfs-… Thanks in advance, -- Lev Veyde Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev(a)redhat.com | lveyde(a)redhat.com <https://red.ht/sig> TRIED.

Renaming or deleting ovirtmgmt
by Gianluca Cecchi 28 Sep '17

28 Sep '17

Hello, I notice that in a cluster I can create a new network and then select it as the Management network, but at the same time the default "ovirtmgmt" logical network in "Manage Networks" is always checked as both as "Assign" and "Required" and also grayed so that I cannot change anything of it... and any host in this cluster must have ovirtmgmt even if it doesn't use it at all.. Is there any RFE to change this model? So for example to be able to change its name or delete it after we have defined a new network as management one. It seems something similar to the concept of the"Default" DC that now we can finally rename and /or delete Gianluca

Huge pages in guest with newer oVirt versions
by Gianluca Cecchi 28 Sep '17

28 Sep '17

Hello, I would like to go again in deep with what preliminary tested and already discussed here: http://lists.ovirt.org/pipermail/users/2017-April/081320.html I'm testing an oVirt node in 4.1.6-pre I don't find the vdsm hook for huge pages; doing a search I get these: vdsm-hook-ethtool-options.noarch : Allow setting custom ethtool options for vdsm controlled nics vdsm-hook-fcoe.noarch : Hook to enable FCoE support vdsm-hook-openstacknet.noarch : OpenStack Network vNICs support for VDSM vdsm-hook-vfio-mdev.noarch : Hook to enable mdev-capable devices. vdsm-hook-vhostmd.noarch : VDSM hook set for interaction with vhostmd vdsm-hook-vmfex-dev.noarch : VM-FEX vNIC support for VDSM Did anything change between 4.1.1 and 4.1.5/4.1.6? I'm making preliminary tests with an Oracle RDBMS and HammerDB in both a physical server and a "big" VM inside another same hw server configured with oVirt. Results are not bad, but I would like to see having huge pages inside the guest how could change results. Just for reference: The 2 Physical server are blades with each one: 2 sockets, each one with 14 cores and ht enabled, so in total 56 computational threads 256Gb ram huge pages enabled VM configured with this virtual hw on one of them: 2 sockets, each one with 6 cores and ht so in total 24 computational threads 64Gb ram no huge pages at the moment Oracle SGA is 32Gb on both physical rdbms and virtual one. Thanks for any insight to test huge pages in guest Gianluca

oVirt Node update question
by Matthias Leopold 28 Sep '17

28 Sep '17

hi, i still don't completely understand the oVirt Node update process and the involved rpm packages. We have 4 nodes, all running oVirt Node 4.1.3. Three of them show as available updates 'ovirt-node-ng-image-update-4.1.6-0.1.rc1.20170823083853.gitd646d2f.el7.centos' (i don't want run release candidates), one of them shows 'ovirt-node-ng-image-update-4.1.5-1.el7.centos' (this is what i like). The node that doesn't want to upgrade to '4.1.6-0.1.rc1' lacks the rpm package 'ovirt-node-ng-image-update-4.1.3-1.el7.centos.noarch', only has 'ovirt-node-ng-image-update-placeholder-4.1.3-1.el7.centos.noarch'. Also the version of ovirt-node-ng-nodectl is '4.1.3-0.20170709.0.el7' instead of '4.1.3-0.20170705.0.el7'. This node was the last one i installed and never made a version update before. I only began using oVirt starting with 4.1, but already completed minor version upgrades of oVirt nodes. IIRC this 'mysterious' ovirt-node-ng-image-update package comes into place when updating a node for the first time after initial installation. Usually i wouldn't care about all of this, but now i have this RC update situation that i don't want. How is this supposed to work? How can i resolve it? thx matthias

Dear Ovirt documents maintainers is this document still valid? https://www.ovirt.org/documentation/data-warehouse/Data_Warehouse_Guide/ When I go one level up it is bringing an empty page: https://www.ovirt.org/documentation/data-warehouse/ Thanks, Arman.

Qemu prevents vm from starting up properly
by M R 27 Sep '17

27 Sep '17

Hello! I have followed instructions in https://www.ovirt.org/ develop/developer-guide/vdsm/hook/qemucmdline/ After adding any command for qemu cmdline, vm will try to start, but will immediately shutdown. Is this a bug? or is the information in the link insufficient? If it would be possible to confirm this and if there's a way to fix, I would really like to have step by step guide of how to get this working. thank you, Mikko

Restrict a single storage domain for users/roles
by Marco Paolone 27 Sep '17

27 Sep '17

Hello, this is my first message on ML. First off, a short recap: I'm setting up an oVirt test environment based on version 4.1.5.2. Once in production, I'm planning to let users access the dashboard with a custom role for basic operations (like startup, shutdown or creation of VMs). For storage domains I'm using both NFS and Cinder, and I'd like to know if there's a way to limit, for users, creation of new volumes only on Cinder. Best regards, Marco

Hi, I was trying to initialize more than one nic via cloud init using ansible as shown below vars: myNicList: [ { nic_name: "eth0, nic_boot_protocol: "dhcp", nic_on_boot: "true"},{ nic_name: "eth0, nic_boot_protocol: "dhcp", nic_on_boot: "true"} ] ovirt_vms: auth: "{{ ovirt_auth }}" name: test ... cloud_init_nics : "{{ myNicList }}" Here I am getting error object is type none. When I tired to debug ovirt_vms module it showed me below outpu: cloud_init_nics: [ {}, {} ] My quesion is, how can I pass list of dictionary in ansible to ovirt_vms via variable ? Please help me, I am stuck. Thanks, ~Rohit
