This is a multi-part message in MIME format. --------------475BA67D91FEE60A922CE8E8 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit Hello, I've a Epyc-based Supermicro Server that should act as ovirt host by using ovirt-node-next installed on ISCSI Boot Target. I already installed an EFI bootable OS (Ubuntu 16.04) on the Hardware using ISCSI Target as Boot-Disk. So far that works. If I try to install ovirt-node-next (tried ovirt-node-ng-installer-ovirt-4.2-2018032906.iso, ovirt-node-ng-installer-ovirt-4.2-2018040306.iso mounted via KVM as CD) I'm not able to use auto-partitioning nor manual partitioning to set the system up. Accessing the ISCSI Target (50GB) works. I created all the mount-points, including /boot and EFI System Partition /boot/efi. The installer automatically proposes /, /var /home and swap on thinpool LVMs which is ok. After having it ready the installer either doesn't accept "Done" as if no EFI Partition was prepared. If I highlight the EFI Partition and click Done it works but the Installer overview doesn't allow to start installation and storage configuration ist marked with a warning sign. The system is booted definitely via EFI from th installer CD.

Q: Change MAC address of an existing VM
by Andrei Verovski 04 Apr '18

04 Apr '18

Hi, Change MAC address of an existing VM: Compute -> Virtual machines -> Edit network -> Custom Mac Address This will change MAC address of only ONE VM, right ? Not for all VMs connected to the same ovirt-mgmt interface. Thanks Andrei

Disable OVS?
by Jayme 03 Apr '18

03 Apr '18

I'm constantly seeing this error in all of my host syslogs: ovs-vsctl: ovs|00001|db_ctl_base|ERR|unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory) My cluster is set to linux bridge and not using OVS. How can I stop the error message or disable ovs?

Why is host rebooted after updates, can it be disabled?
by Jayme 03 Apr '18

03 Apr '18

I notice that almost every time I perform an oVirt host upgrade the host is automatically rebooted. Why is this done and is there a way to disable the automated reboot process?
