Nesting Hyper-V
by Nathan Llaneza 07 Oct '14

07 Oct '14

Hello All, I work for a educational institution, and we currently use oVirt in our datacenter. We are on the latest stable build of oVirt 3.4.4. Most of our hypervisors run CentOS 6.5; however, we have recently been asked if we could assign virtual hypervisors (Server 2012 R2) to some of our classes for learning purposes. I have been doing some research and found that I needed atleast kernel 3.10; therefore, I took one hypervisors and converted it to CentOS 7 fully patched. I also installed the nestedvt hook as described here <http://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kvm/>. I am all researched/googled out, and I am having no luck. After I do a typical install of Server 2012 R2 it will not let me install the Hyper-V role. I quote "Hyper-V cannot be installed: A hypervisor is already running". When I run the command cat /sys/module/kvm_intel/parameters/nested it comes back with a "Y". If I look in the host hooks it shows the nestedvt and macspoof. The VM has a custom property of macspoof = true. Did I miss something? Is this possible? Has anyone done this before? Thank you in advance for all you do. Your work on this project has helped our community college greatly and our student even more. Because of this project we have be able to give students virtual resources to complete their labs from anywhere at anytime.

Hi All, This is not a issue or problem, more like a question... Is it possible for the next upcomming ovirt release to put all the necesarry file back in 1 repo in stead of 3 or 4 different ones? Because when you have your own local mirrors... This is not so nice to manage... Just asking... :-) Kind regards, Koen

Restoring backed up VM

This is a multi-part MIME message. --=_reb-r3E2C9F17-t5431F02A Content-Type: text/plain; charset="utf-8"; format=flowed Content-Transfer-Encoding: 7bit Hi I am trying to backup and restore the VM using the flow suggester at Features/Backup-Restore API Integration <http://www.ovirt.org/Features/Backup-Restore_API_Integration#VM_Backup.2FRe…> When I tried to restore the VM using the following steps, _*Full Virtual Machine Restoration*_ 1. Create disks for restore 2. Attach the disks for restore to the virtual appliance (Restore the data to it) 3. Detach the disks from the virtual appliance. 4. Create a vm using the configuration that was saved as part of the backup flow - (added capabillity to oVirt as part of the Backup API) 5. Attach the restored disks to the created vm. I encountered following error at step 4. <fault> <reason>Operation Failed</reason> <detail>[Import VM failed - _*VM Id already exist in the system*_. Please remove the VM (RHEL_65_CL1_CLONE2) from the system first]</detail> </fault> I have not deleted/removed the backed up VM from the system. Is it expected behaviour? Should it not overwrite the existing VM or Create new VM with different VM Id, if the backup up VM exists?

Harmful to rename a cluster?
by Nicolas Ecarnot 07 Oct '14

07 Oct '14

Hi, For reasons beyond sanity, I will have to rename a cluster to something, then rename it back to its previous name. - Is it only a label with no impact on a production datacenter? - Will it be possible to rename it back? Won't oVirt remember a previous similar name was used and prevent me from doing so? Thank you -- Nicolas Ecarnot

Proper way to change and persist vdsm configuration options
by Trey Dockendorf 07 Oct '14

07 Oct '14

I'm running ovirt nodes that are stock CentOS 6.5 systems with VDSM installed. I am using iSER to do iSCSI over RDMA and to make that work I have to modify /etc/vdsm/vdsm.conf to include the following: [irs] iscsi_default_ifaces = iser,default I've noticed that any time I upgrade a node from the engine web interface that changes to vdsm.conf are wiped out. I don't know if this is being done by the configuration code or by the vdsm package. Is there a more reliable way to ensure changes to vdsm.conf are NOT removed automatically? Thanks, - Trey

[QE][ACTION REQUIRED] oVirt 3.5.0 status - Go / No Go
by Sandro Bonazzola 07 Oct '14

07 Oct '14

Hi, We started composing oVirt 3.5.0 GA yesterday 2014-10-06 and we finished collecting rpms this morning. While we would have liked to be able to release it, bugzilla shows 2 new fresh blockers, so it's another No Go. The bug tracker [1] shows 2 blockers: Bug ID Whiteboard Status Summary 1149637 virt ASSIGNED Cannot start VM with attached ISO 1149705 storage NEW VM abnormal stop after LV refreshing when using thin provisioning on block storage This means a RC5 build will be issued once the above 2 bugs will be fixed and GA will follow after testing. Please provide an ETA for above bugs. The bugs keyworded as Regression have been reviewed by maintainers and not marked as blockers[4] Features completed are marked in green on Features Status Table [2] There are still 33 bugs [3] targeted to 3.5.0 which will be moved automatically to 3.5.1 once the build will be released. Maintainers / Assignee: If you're aware of something that should block the release, please raise it as soon as possible.

Add additional iSCSI path in ovirt 3.3.4
by Thomas Scofield 06 Oct '14

06 Oct '14

I am trying to add a second path to my iSCSI LUNs but I can’t get the changes to persist. I can get the SPM to login to the second path, and from the server side the multipath –ll output looks good. I can then move the SPM around to force all the other systems to login to the iSCSI LUNs. But when I reboot a node I lose the second path. I have also been searching through the database to see what might be missing on the backend and I noticed that the second path is not listed in the storage_server_connections table. I tried adding an entry for the second path, but that did not resolve the problem. What is the proper way to add an additional path?

Re: [ovirt-users] Can not configure with simple LDAP.

Hi, Alon, Without waiting until the weekend, I have finished the flesh install of the oVirt 3.5 RC3 today. As a result, with same AAA settings, My OpenLDAP's users became possible to login to the Web User Portal now. Yes, RC3 is good for integrating with newest OpenLDAP 2.4.23, RC2 is not.
