Newbie Questions
by Dirk Streubel 20 Nov '19

20 Nov '19

Hello, i'am a new user and i have a few questions, maybe somebody can Help. It is possible to install the Server Management on a Raspberry PI 4 with 4GB. I find in the official Re Hat Document "Red Hat Virtualization Manager Hardware Requirements" that 4GB RAM is enough. And the PI has a 128 GB Flash Card. Would it work? Have somebody tested it? Another Question: Since yesterday i am trying to ad a host in my environment on ovirt Version 4.3.6. My Server Management runs under Fedora 31 under KVM/Virt-Manager without any problems. Adding a new Host doesn't work. I have tried to ad another VM with 8 Cores and 32 GB RAM as a host. This is not working, maybe VMs in VMs under ovirt is not possible, i don't know. So i try a physical Machine here as a Host. This and the other Installations fails with the Information: no route to Host. I found a bug and it says that the bug is closed. In the bug stand that maybe something wrong with the openvswitch. So i tried the following commands on the Server Management: ovn-nbctl show and ovn-sbctl show and the output was nothing. journalctl -xfe on the host that i want to migrate gave my the output: Nov 17 10:30:38 hypervisor1.linux.fritz.box sshd[12632]: Accepted keyboard-interactive/pam for root from 10.2.0.99 port 43260 ssh2 Nov 17 10:30:38 hypervisor1.linux.fritz.box systemd-logind[960]: New session 5 of user root. -- Subject: A new session 5 has been created for user root -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- Documentation: http://www.freedesktop.org/wiki/Software/systemd/multiseat -- -- A new session with the ID 5 has been created for the user root. -- -- The leading process of the session is 12632.

Re: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing

Hi Sahina, I have a strange situation: 1. When I try to access the file via 'sudo -u vdsm dd if=disk of=test bs=4M' the command fails on aprox 60MB. 2. If I run same command as root , remove the file and then run again via vdsm user -> this time no i/o error reported. My guess is that I need to check what's going on the bricks themselve ... Best Regards, Strahil Nikolov

Re: Warning: out of sync hosts ovirt-node3 ?
by Strahil 20 Nov '19

Go to Compute -> Hosts -> select the host and go to network tab. Click on it and check if it is 'out of sync'. There is a button (somewhere on the right ) to sync all networks.

I am new to this whole technology and I can't find anything about thin clients. I was wondering if I can even use oVirt with a thin client, if anyone knows how help would be much appreciated. I am also wondering if there is a way to use a Raspberry Pi as a thin client.
