[ACTION NEEDED] ovirt-engine-3.5 branch update
by Sandro Bonazzola 09 Jul '14

09 Jul '14

Hi, We're going to refresh ovirt-engine-3.5 branch tomorrow 2014-07-08 at 08:00 UTC. If you have any commits that are relevant only for 3.6 and not for 3.5, please don't merge them yet until we'll update the 3.5 stable branch. An email with the exact cutoff commits sha will be sent once the branch is updated. After branch update patch targeted to 3.5 will need to be cherry-picked to 3.5 branch too. -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

Hi, I want to create a live snapshot of VM, but it failed with the following error :- There are 3 event logs : - - Snapshot '3July' creation for VM 'test' was initiated by admin. - Failed to create live snapshot '3July' for VM 'test'. VM restart is recommended. - Failed to complete snapshot '3July' creation for VM 'test'. Please help me to find some workaround for this... Thanks, Punit

Best way to clone host
by Brad Bendy 09 Jul '14

09 Jul '14

Hi, Ive got host that im running on USB sticks, the install takes hours as the USB is such a slow write speed. Ive made a copy via DD and cloned to a new USB which works fine. But when I change the IP and after reboot the old IP goes back. My thought process was change the IP, then add the host into the GUI, it will not install any packages since it's all installed but would change the certs and everything else. Any ideal what the best way to handle this is? Or should I just take 2 hours and install each host on it's own? I would think the same concept could be used for users wanting to PXE boot multiple hosts. Thanks

oVirt Node ISO for 3.5-pre
by Fabian Deutsch 09 Jul '14

09 Jul '14

Hey, here is another draft ISO which is intended to be used for testing with oVirt 3.5. This ISO also provides for the first time the oVirt Node Hosted Engine plugin. http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt… We've learned from the past: To circumvent some SELinux issues, please append enforcing=0 to the kernel commandline on boot. And please provide us your feedback, so we can take a look and address the problem. Greetings fabian

Network setup
by Dwight Schauer 09 Jul '14

09 Jul '14

Hello oVirt users, I'm running into network setup problems. http://www.ovirt.org/Vdsm_Network Shows this as a supported topology. bridge1 --- v1 --- bond --- nic1 bridge2 --- v2 --/ \-- nic2 Problem is I have to configure at least this on each host in order to the connect to an activate: v1 --- bond --- nic1 \-- nic2 Which oVirt does not like because I already created the bond and attached a vlan interface to it. So I configured this ahead of time (without vdsm) bridge1 --- v1 --- bond --- nic1 bridge2 --- v2 --/ \-- nic2 Those work fine. I can use each bridge statically or with DHCP. Problem is that oVirt refuses to use the bridge interfaces (they don't show up in the web gui), it only wants to use the bond interface. If I was using libvirt/kvm-manager I would preconfigure this (without vdsm): bridge1 --- v1 --- bond --- nic1 bridge2 --- v2 --/ \-- nic2 And I'm be able to run VMs on other VLAN. (Which is what I want to achieve with oVirt). Is there a way I can achieve what I need to do (connecting VMs to either VLAN) with one of my preconfigured setups without resorting to another nic (or bonded pair?) -- Dwight

MASTER storage domain concept
by Nicolas Ecarnot 09 Jul '14

09 Jul '14

Hi, Some month ago, in a thread not directly related to this, someone from Redhat wrote that the limitation about the master storage domain is being worked on to get removed. This someone may have been Itamar but I'm not sure. May you explain a little bit further : - what is the difference between a master storage domain and a storage domain, except the master is the default and first one? - when this limitation will be removed, will the concept remain, but we will have the ability to migrate it, as we can do now with the SPM for example? - or will it remain but be hidden somewhere? - or will it be completely removed? There is no emergency on our side, just a need to understand. Thank you. -- Nicolas Ecarnot

Migrate from one system to another.
by John Gardeniers 09 Jul '14

09 Jul '14

Hi All, I've been googling but haven't found an answer to what I thought would be a fairly simple question. The systems involved are RHEV but, given that Red Hat support has been less than stellar and doesn't have a user discussion list and that RHEV is just Ovirt anyway, I thought I'd ask here. We need get get a VM from our client's system in the UK to our system in Australia, so this isn't just migrating between clusters or datacenters. I know it's easy enough to export a VM and copy its image file from the export storage area but what's the procedure to import it into the second system? Can I just plonk the file into out import/export storage (I really doubt it) or do I need to do something else with it? I know I can import it easily enough into a KVM/Qemu system and then do a V2V from there but that seems like a step that shouldn't be required. Have I missed something really obvious or is this one of those things people don't do very often? regards, John
