Cannot access Engine VM
by Steven Bach 18 Aug '20

18 Aug '20

Hello All, I installed Ovirt node 4.4.1.5 from the ovirt ISO, IP 192.168.1.53/24 I setup the self hosted engine by logging into the web interface, configured it for 192.168.1.55/24 IP on the default generated bridge interface and setup a FQDN that is resolvable via DNS. Setup NFS storage, and all seems good. The Engine VM is running, but I cannot access it at all outside the node. SSH'd in the node I can ping the engine, anything else on that same subnet cannot SSH or even ping it (Again, DNS is resolving correctly to the IP Address). I am able to SSH into the engine from the node. While SSH'd into the Engine from the node, I can only ping the Node and nothing beyond that, not able to install ovirt repo, nothing. Any ideas are greatly appreciated, thank you, -- Steven Bach sbach(a)bachnetworks.com

Uploading images from the UI was available in ovirt 4.4.0, but is fully functional since ovirt 4.4.1. We know about hone issue - if you replaced apache certificates with 3rd party certificates, uploading via ovirt-imageio service on engine host (as a proxy) will not work: https://bugzilla.redhat.com/1866745 https://bugzilla.redhat.com/1862107 If you are using engine built certificates, upload and download should work. We may have more info about the failure in engine log. Please share the log showing the time when you tried to upload an image. Nir

How to diable dhcp in ovirt network
by Adam Xu 17 Aug '20

17 Aug '20

Hi everyone Recently, when I install okd on ovirt. The installation process was failed because the vm automatically acquired an IP address from DHCP before the installer assigned it. Our DHCP is enabled by a layer 3 switch, I tried to diable dhcp using network filter. but there is no entry related to blocking the DHCP feature. Is there any way for ovirt to disable DHCP? -- Adam Xu

oVirt nested on oVirt works, when you enable MAC spoofing on host VMs
by thomas＠hoberg.net 13 Aug '20

13 Aug '20

Howto: Create a new network profile that doesn't have the MAC spoofing filter included. In my case I used one without any filters, you may want to be more careful. Background: I had tried the nested approach with the default settings and found that the hosted-engine setup worked just find to the point where it was running as a nested VM on the install node, but that it failed to tie in the other gluster nodes or to communicate to the outside: There was something wrong with the network, but no obivous failures. I tried using other, simpler "client hypervisors" (it's all KVM anyway) VirtualBox and 'native' KVM and the symptoms were the same: The VMs ran just fine, but the network didn't connect. And then I remembered that obviously a Hypervisor need to override the MAC for each client VM if you want full network access and I had come across "no-mac-spoofing" often enough it somehow stayed on my mind... and finally it clicked. Anyhow, validing full functionality now and the main interest in this is the ability to do a full simulation/testing of oVirt 4.3->4.4 upgrades on 3-node HCI setups, which I'd rather not do on the live physical system. Of course, it's also quite cool!

Support for Shared SAS storage
by Vinícius Ferrão 13 Aug '20

13 Aug '20

Hello, I’ve two compute nodes with SAS Direct Attached sharing the same disks. Looking at the supported types I can’t see this on the documentation: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html There’s is local storage on this documentation, but my case is two machines, both using SAS, connected to the same machines. It’s the VRTX hardware from Dell. Is there any support for this? It should be just like Fibre Channel and iSCSI, but with SAS instead. Thanks,
