Migration oVirt Engine from Dedicated Host to Self-Hosted Engine
by FERNANDO FREDIANI 19 Mar '18

19 Mar '18

Hello folks I currently have a oVirt Engine which runs in a Dedicated Virtual Machine in another ans separate environment. It is very nice to have it like that because every time I do a oVirt Version Upgrade I take a snapshot before and if it failed (and it did failed in the past several times) I just go back in time before the snapshot and all comes back to normal. Two quick questions: - Going to a Self-Hosted Engine will snapshots or recoverable ways be possible ? - To migrate the Engine from the current environment to the self-hosted engine is it just a question to backup the Database, restore it into the self-hosted engine keeping it with the same IP address ? Are there any special points to take in consideration when doing this migration ? Thanks Fernando

VM has been paused due to NO STORAGE SPACE ERROR ?!?!?!?!
by Enrico Becchetti 19 Mar '18

19 Mar '18

Dear All, Does someone had seen that error ? When I run this command from my virtual machine: # time dd if=/dev/zero of=enrico.dd bs=4k count=10000000 VM was paused due to kind a storage error/problem. Strange message because tell about "no storage space error" but ovirt puts virtual machine in a paused state. Inside events from ovirt web interface I see this: "VM has been paused due to lack of storage space" but no ERROR found in /var/log/vdsm.log. My oVirt enviroment 4.2.1 has three hypervivosr with FC storage and before now I haven't see any other problem during the normal functioning of the vm , it's seem that this error occurs only when there is massive I/O. Any ideas ? Thanks a lot.

How to disable the QoS settings (go back to 'Unlimited' state) in the vNIC profile by using oVirt REST API?
by Shao-Da Huang 19 Mar '18

19 Mar '18

Hi, I have a vNIC profile with a QoS object: <vnic_profile> <name>vnic_test</name> <network id="00000000-0000-0000-0000-000000000009"/> <qos id="74de92de-3cea-449c-b82e-4655802698c5"/> <pass_through> <mode>disabled</mode> </pass_through> <port_mirroring>false</port_mirroring> </vnic_profile> Now I try to update this object using PUT method and set the 'pass_through' mode to 'enabled', But I always got the error message "Cannot edit VM network interface profile. 'Port Mirroring' and 'Qos' are not supported on passthrough profiles." no matter I send the request body like: <vnic_profile> <name>vnic_test</name> <network id="00000000-0000-0000-0000-000000000009"/> <pass_through> <mode>enabled</mode> </pass_through> <port_mirroring>false</port_mirroring> </vnic_profile> OR <vnic_profile> <name>vnic_test</name> <network id="00000000-0000-0000-0000-000000000009"/> <pass_through> <mode>enabled</mode> </pass_through> </vnic_profile> Could anyone tell me how to disable the related QoS settings (namely go back to 'Unlimited' state) in a vNIC profile by using REST API?

Query about running ovirt-4.2.1 engine support 3.x nodes ?

--_000_DM5PR1601MB1307870A4A315F7E754AD0F688D10DM5PR1601MB1307_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Hello All, I have two hopefully easy questions regarding an ovirt-4.2.1 engine support= and 3.x nodes ? 1) Does an ovirt-4.2.x engine support 3.x nodes ? As This page states: "The cluster compatibility is set according to the version of the least cap= able host operating system in the cluster." https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks/ Which seems to indicate that you can run say a 4.2.1 engine with lower vers= ion nodes, but is that correct ? 2) And can you just upgrade the nodes directly from 3.x to 4.2.x as per the= se steps ? 1. Move the node to maintenance 2. Add 4.2.x repos 3. yum update 4. reboot 5. Activate (exit maintenance) I've looked in the release notes but wasn't able to find much detail on ovi= rt-nodes upgrades.
