Looking for paid support long term
by vip＠ahit.be 27 Oct '21

Hi We are a server building company, we already supply 2-3 high availability storage clusters/virtualization per month based on commercial/paid software. For lower end clients we like to use oVirt hyperconverged, would like support/share knowledge with my team. I have a team of 5 technicians who need training. First we need help setting up a virtual oVirt cluster. Once this works, we will test performance/stability/features/.... If we're happy with the solution, my team needs training and also if we encounter a very difficult issue we would like to have a paid support channel. I would prefer a partner who has at least 3 engineers [ holidays etc ]. Do you have a lot of experience with your team, please PM me. Thanks.

Cancelling a running/stuck task
by Dominique D 26 Oct '21

Hello, Yesterday I had a network failure and my (3) oVirt 4.4.6 servers restarted. Two out of 3 servers are functional now but I have tasks (20) in progress which no longer work. How do I erase them? taskcleaner.sh? Are there any risks of using this script? Here is a printscreen of the tasks https://drive.google.com/file/d/1bZL0c4G6_MDgCtNfzmjXJb_snLYW9fDU/view?usp=…

TPM 2.0 Support in Ovirt
by bob.franzke＠mdaemon.com 22 Oct '21

22 Oct '21

Need to deploy a VM of a Windows 11 guest. Windows 11 requires TPM 2.0 support for it to be able to install. Does Ovirt support TPM devices somehow and if so how do I present the VM with a TPM device that can be detected by the Windows 11 setup installer? Thanks in advance for any help here.

The only workaround for now is to use a file based storage domain (e.g. NFS) for the ISO images. When the issue is fixed, you can copy the ISO disks to another storage domain, and remove the file based domain. Nir

install python package ovirt_imageio for Ovirt 4.3
by Grace Chen 21 Oct '21

21 Oct '21

I want to use python script running from a host to automate the remote kvm manager's vm backup. Our ovirt version is 4.3. I have installed ovirt-imageio-daemon on the host I tried to yum install ovirt-imageio-client (we use yum), it couldn't find the package. error message: Loaded plugins: ulninfo, vdsmupgrade, versionlock ovirt-4.3 | 3.0 kB 00:00:00 ovirt-4.3-extra | 3.0 kB 00:00:00 ovirt-master-snapshot | 3.0 kB 00:00:00 ovirt-master-snapshot-static | 3.0 kB 00:00:00 No package ovirt-imageio-client available. I tried to copy folder ovirt_imageio from ovirt-imageio to my python library directory, it could not compile the c file "ioutil.c" Can anybody help me install the python package? Am I installing on the correct place, do I need to use the python script only on the host that installed the kvm manager?

oVirt 4.4.8 Hyperconverged deploy failed
by dvx.mellin＠gmail.com 21 Oct '21

21 Oct '21

Hi everyone, I'm trying to deploy a hyperconverged ovirt cluster, but the the wizard in cockpit failed at the first step with the error "FQDN is not reachable". The goal is to have 3 nodes, with hosted engine on gluster FS. Here is the relevant information : - CentOS 8.4 - ovirt 4.4.8 - 2 network interfaces (1 for storage, 1 for production) The packages installed : cockpit-ovirt-dashboard, vdsm-gluster, ovirt-host, ovirt-engine-appliance, gluster-ansible-roles # rpm -qa | grep ovirt ovirt-imageio-client-2.2.0-1.el8.x86_64 ovirt-host-dependencies-4.4.8-1.el8.x86_64 ovirt-vmconsole-1.0.9-1.el8.noarch python3-ovirt-setup-lib-1.3.2-1.el8.noarch ovirt-provider-ovn-driver-1.2.34-1.el8.noarch ovirt-host-4.4.8-1.el8.x86_64 ovirt-vmconsole-host-1.0.9-1.el8.noarch ovirt-imageio-daemon-2.2.0-1.el8.x86_64 ovirt-hosted-engine-ha-2.4.8-1.el8.noarch ovirt-hosted-engine-setup-2.5.3-1.el8.noarch ovirt-engine-appliance-4.4-20210826223909.1.el8.x86_64 cockpit-ovirt-dashboard-0.15.1-1.el8.noarch python3-ovirt-engine-sdk4-4.4.15-1.el8.x86_64 ovirt-ansible-collection-1.6.2-1.el8.noarch ovirt-imageio-common-2.2.0-1.el8.x86_64 I didn't use the ovirt44-release package because we have to use our local repo. So we have cloned all necessary repo. Every package installation was passed without any issues. The /etc/hosts contains every FQDN/IP for the storage network (which is not exposed to the public), and the DNS server is reachable to respond to public FQDN. Passwordless connection is installed and works perfectly with sotrage and production FQDN. If you need more information, please tell me. Thanks in advance for your help. Regards
