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,

Is the udev settling issue more wide spread? Getting failed 'qemu-img -convert' also while copying disks between data and vmstore domains
by thomas＠hoberg.net 12 Aug '20

12 Aug '20

While trying to diagnose an issue with a set of VMs that get stopped for I/O problems at startup, I try to deal with the fact that their boot disks cause this issue, no matter where I connect them. They might have been the first disks I ever tried to sparsify and I was afraid that might have messed them up. The images are for a nested oVirt deployment and they worked just fine, before I shut down those VMs... So I first tried to hook them as secondary disks to another VM to have a look, but that just cause the other VM to stop at boot. Also tried downloading, exporting, and plain copying the disks to no avail, OVA exports on the entire VM fail again (fix is in!). So to make sure copying disks between volumes *generally* work, I tried copying a disk from a working (but stopped) VM from 'vmstore' to 'data' on my 3nHCI farm, but that failed, too! Plenty of space all around, but all disks are using thin/sparse/VDO on SSD underneath. Before I open a bug, I'd like to have some feedback if this is a standard QA test, this is happening to you etc. Still on oVirt 4.3.11 with pack_ova.py patched to wait for the udev settle, This is from the engine.log on the hosted-engine: 2020-08-12 00:04:15,870+02 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-67) []
