Several virtual machines all with the same MAC address ?
by Li Xo 17 Mar '20

17 Mar '20

Hello, I need to replicate some file servers that must have the same MAC address to work properly and which will be placed on different VLANs to avoid MAC conflicts. With VMware and VirtualBox this is quite simple and works without particular problems but it seems that oVirt does not allow it or I did not find how to proceed. So 2 questions: - does it is possible ? - what must be done to allow oVirt to handle it ? Thanks, Li

Storage Domain already attached to a Data Center
by Anton Louw 17 Mar '20

17 Mar '20

Hi All, I created a little test environment for myself, just to test a few things. The initial test I wanted to do was to see if I can create a new HE, add it to a different Storage Domain, and then import my existing Storage Domains. Everything went through 100%, except for the little option I forgot to select, and that is to put the original Data Center in maintenance. Now, when I want to import my storage domains, it tells me that the storage domain is already attached to a data center. Is there any way that I can remove this storage domain from my original data center through one of my nodes? I would power up the old HE, but I have powered it off just before deploying a new HE. I am having the same issue with a node as well, so if there is a way to remove the node from the Data Center as well, that would be awesome. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

I configured my DWH scale with scales that I would like to report on. I checked this morning, and the last row in my PostgreSQL DB is from the 9th. I checked the logs, and I see that it is referring to an “ETL Service” which I am not familiar with. I have attached the lines in the text document. Where is this from? If from the engine db, please check also: /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log Then try to (re)start it with: systemctl restart ovirt-engine-dwhd.service ETL is a common name in the industry for what dwhd does: Extract, Transform, Load. > > > > If anybody could point me in the right direction, it would be greatly appreciated. > > > > Thank you > > > Anton Louw > Cloud Engineer: Storage and Virtualization at Vox > ________________________________ > T: 087 805 0000 | D: 087 805 1572 > M: N/A > E: anton.louw(a)voxtelecom.co.za > A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg > www.vox.co.za > > > > > > > > > Disclaimer > > The contents of this email are confidential to the sender and the intended recipient.

Hi All, What would be the easiest way to migrate my hosted engine disk from one storage domain, to another? I see that I can click on the disk, and select move, but for some reason I feel nervous about it :) Thanks

Client separation on bridge level
by Hendrik Peyerl 16 Mar '20

16 Mar '20

Hello everyone, is there a way to seperate the traffic between VMs on the same bridge on one oVirt-node with built-in tools from ovirt? We have VMs using the same bridge which should never be able to talk to each other. We are currently using ebtables for that, but its not working very good anymore now that we upgraded to 4.3 with firewalld. Any suggestions would be greatly appreciated. Best regards, Hendrik
